She asks the TED community to help her build a Charter for Compassion -- to help restore the Golden Rule as the central global religious doctrine.
Accepting his 2008 TED Prize, physicist Neil Turok speaks out for talented young Africans starved of opportunity: by unlocking and nurturing the continent's creative potential, we can create a change in Africa's future. Turok asks the TED community to help him expand the African Institute for Mathematical Sciences by opening 15 new centers across Africa in five years. By adding resources for entrepreneurship to this proven model, he says, we can create a network for progress across the continent -- and perhaps discover an African Einstein.

Clifford Stoll could talk about the atmosphere of Jupiter. Or hunting KGB hackers. Or Klein bottles, computers in classrooms, the future. But he's not going to. Which is fine, because it would be criminal to confine a man with interests as multifarious as Stoll's to give a talk on any one topic. Instead, he simply captivates his audience with a wildly energetic sprinkling of anecdotes, observations, asides -- and even a science experiment. After all, by his own definition, he's a scientist: "Once I do something, I want to do something else."

Alan Russell studies regenerative medicine -- a breakthrough way of thinking about disease and injury by helping the body to rebuild itself. He shows how engineered tissue that "speaks the body's language" has helped a man regrow his lost fingertip, how stem cells can rebuild damaged heart muscle, and how cell therapy can regenerate the skin of burned soldiers. This new, low-impact medicine comes just in time, Russell says -- our aging population, with its steeply rising medical bills, will otherwise (and soon) cause a crisis in health care systems around the world. Some graphic medical imagery.
In this deceptively casual talk, Charles Leadbeater weaves a tight argument that innovation isn't just for professionals anymore.

Negative images of Africa dominate the news: famine and disease, conflict and corruption. But Ngozi Okonjo-Iweala, the former Finance Minister of Nigeria and now a director of the World Bank, says there's a less-told story unfolding in many African nations: one of reform, economic growth and business opportunity. Cracking down on corruption -- and the perception of corruption -- will be the key to its success. She tells how high-ranking Nigerian officials taking money illicitly have been jailed, and how citizens and prospective business partners are getting at least a partial picture now of where money flows.
Author Robert Wright explains "non-zero-sumness," a game-theory term describing how players with linked fortunes tend to cooperate for mutual benefit. This dynamic has guided our biological and cultural evolution, he says -- but our unwillingness to understand one another, as in the clash between the Muslim world and the West, will lead to all of us losing the "game." Once we recognize that life is a non-zero-sum game, in which we all must cooperate to succeed, it will force us to see that moral progress -- a move toward empathy -- is our only hope.

Stunning imagery of cosmological wonders show us the universe as we know it now. Speaking as "a concerned member of the human race," Rees harkens to the wisdom of Einstein, calling for scientists to act as moral compasses, confronting the coming developments and ensuring our role in "the immense future."
In this bracingly honest and funny talk, international security strategist Thomas P.M. Barnett outlines a post-Cold War solution for the foundering US military: Break it in two.

As machines take on more jobs, many find themselves out of work or with raises indefinitely postponed. Is this the end of growth? No, says Erik Brynjolfsson -- it’s simply the growing pains of a radically reorganized economy. A riveting case for why big innovations are ahead of us … if we think of computers as our teammates. Be sure to watch the opposing viewpoint from Robert Gordon. Erik Brynjolfsson examines the effects of information technologies on business strategy, productivity and employment.
When we drive, we get into a glass bubble, lock the doors and press the accelerator, relying on our eyes to guide us — even though we can only see the few cars ahead of and behind us. But what if cars could share data with each other about their position and velocity, and use predictive models to calculate the safest routes for everyone on the road? Jennifer Healey imagines a world without accidents. (Filmed at TED@Intel.)

Taylor Wilson was 14 when he built a nuclear fusion reactor in his parents' garage. Now 19, he returns to the TED stage to present a new take on an old topic: fission. Wilson, who has won backing to create a company to realize his vision, explains why he's so excited about his innovative design for small modular fission reactors — and why it could be the next big step in solving the global energy crisis.
Economics PhD Sebastião Salgado only took up photography in his 30s, but the discipline became an obsession. His years-long projects beautifully capture the human side of a global story that all too often involves death, destruction or decay. Here, he tells a deeply personal story of the craft that nearly killed him, and shows breathtaking images from his latest work, Genesis, which documents the world's forgotten people and places.
What if Andy Warhol had it wrong, and instead of being famous for 15 minutes, we’re only anonymous for that long? In this short talk, Juan Enriquez looks at the surprisingly permanent effects of digital sharing on our personal privacy. He shares insight from the ancient Greeks to help us deal with our new “digital tattoos.”
Rita Pierson, a teacher for 40 years, once heard a colleague say, "They don't pay me to like the kids." Her response: "Kids don't learn from people they don’t like.’” A rousing call to educators to believe in their students and actually connect with them on a real, human, personal level.
In this well-argued talk, Timothy Bartik makes the macro-economic case for preschool education — and explains why you should be happy to invest in it, even if you don't have kids that age (or kids at all). The economic benefits of well-educated kids, it turns out, go well beyond the altruistic. (Filmed at TEDxMiamiUniversity.)
For foreigners, learning to speak Chinese is a hard task. But learning to read the beautiful, often complex characters of the Chinese written language may be less difficult. ShaoLan walks through a simple lesson in recognizing the ideas behind the characters and their meaning — building from a few simple forms to more complex concepts. Call it Chineasy.
Until recently, many teachers only got one word of feedback a year: “satisfactory.” And with no feedback, no coaching, there’s just no way to improve. Bill Gates suggests that even great teachers can get better with smart feedback — and lays out a program from his foundation to bring it to every classroom.
It took a life-threatening condition to jolt chemistry teacher Ramsey Musallam out of ten years of “pseudo-teaching” to understand the true role of the educator: to cultivate curiosity. In a fun and personal talk, Musallam gives 3 rules to spark imagination and learning, and get students excited about how the world works.
Pearl Arredondo grew up in East Los Angeles, the daughter of a high-ranking gang member who was in and out of jail. Many teachers wrote her off as having a problem with authority. Now a teacher herself, she’s creating a different kind of school and telling students her story so that they know it's okay if sometimes homework isn’t the first thing on their minds.
Young poet, educator and activist Malcom London performs his stirring poem about life on the front lines of high school. He tells of the “oceans of adolescence” who come to school “but never learn to swim,” of “masculinity mimicked by men who grew up with no fathers.” Beautiful, lyrical, chilling.
Why, why, why does our education system look so similar to the way it did 50 years ago? Millions of students were failing then, as they are now — and it’s because we’re clinging to a business model that clearly doesn’t work. Education advocate Geoffrey Canada dares the system to look at the data, think about the customers and make systematic shifts in order to help greater numbers of kids excel.
In a heart-melting moment, TED Talks Education host John Legend sits at the piano to sing "True Colors," giving the lyrics a special meaning for kids and teachers. "So don't be afraid / to let them show / your true colors / are beautiful, like a rainbow."
Leaving a high-flying job in consulting, Angela Lee Duckworth took a job teaching math to seventh graders in a New York public school. She quickly realized that IQ wasn’t the only thing separating the successful students from those who struggled. Here, she explains her theory of “grit” as a predictor of success.
Sir Ken Robinson outlines 3 principles crucial for the human mind to flourish — and how current education culture works against them. In a funny, stirring talk he tells us how to get out of the educational "death valley" we now face, and how to nurture our youngest generations with a climate of possibility.
Clinical psychologist Meg Jay has a bold message for twentysomethings: Contrary to popular belief, your 20s are not a throwaway decade. In this provocative talk, Jay says that just because marriage, work and kids are happening later in life, doesn’t mean you can’t start planning now. She gives 3 pieces of advice for how twentysomethings can re-claim adulthood in the defining decade of their lives.
In our digital world, social relations have become mediated by data. Without even realizing it, we’re barricading ourselves against strangeness — people and ideas that don't fit the patterns of who we already know, what we already like and where we’ve already been. A call for technology to deliver us to what and who we need, even if it’s unfamiliar. (Filmed at TED@Intel.)
Can a person disappear in plain sight? That’s the question Liu Bolin‘s remarkable work seems to ask. The Beijing-based artist is sometimes called “The Invisible Man” because in nearly all his art, Bolin is front and center — and completely unseen. He aims to draw attention to social and political issues by dissolving into the background.
Why can't two slices of pizza be used as a slide clicker? Why shouldn't you make music with ketchup? In this charming talk, inventor Jay Silver talks about the urge to play with the world around you. He shares some of his messiest inventions, and demos MaKey MaKey, a kit for hacking everyday objects.
It's not a demo, more of a philosophical argument: Why did Sergey Brin and his team at Google want to build an eye-mounted camera/computer, codenamed Glass? Onstage at TED2013, Brin calls for a new way of seeing our relationship with our mobile computers — not hunched over a screen but meeting the world heads-up.
If you're lucky enough to live without want, it's a natural impulse to be altruistic to others. But, asks philosopher Peter Singer, what's the most effective way to give? He talks through some surprising thought experiments to help you balance emotion and practicality — and make the biggest impact with whatever you can share. NOTE: Starting at 0:30, this talk contains 30 seconds of graphic footage.
In art school, Phil Hansen developed an unruly tremor in his hand that kept him from creating the pointillist drawings he loved. Hansen was devastated, floating without a sense of purpose. Until a neurologist made a simple suggestion: embrace this limitation ... and transcend it.
Thinking about death is frightening, but planning ahead is practical and leaves more room for peace of mind in our final days. In a solemn, thoughtful talk, Judy MacDonald Johnston shares 5 practices for planning for a good end of life.
Designer Alastair Parvin presents a simple but provocative idea: what if, instead of architects creating buildings for those who can afford to commission them, regular citizens could design and build their own houses? The concept is at the heart of WikiHouse, an open source construction kit that means just about anyone can build a house, anywhere.
In her quest to become a world-famous violinist, Ji-Hae Park fell into a severe depression. Only music was able to lift her out again — showing her that her goal needn’t be to play lofty concert halls, but instead to bring the wonder of the instrument to as many people as possible.
When the Museum of Modern Art's senior curator of architecture and design announced the acquisition of 14 video games in 2012, "all hell broke loose." In this far-ranging, entertaining, and deeply insightful talk, Paola Antonelli explains why she's delighted to challenge preconceived ideas about art and galleries, and describes her burning wish to help establish a broader understanding of design.
Domestic violence and sexual abuse are often called "women’s issues.” But in this bold, blunt talk, Jackson Katz points out that these are intrinsically men’s issues — and shows how these violent behaviors are tied to definitions of manhood. A clarion call for us all — women and men — to call out unacceptable behavior and be leaders of change.
It’s the dream of kids all around the world to see giant beasts walk the Earth again. Could — and should — that dream be realized? Hendrik Poinar gives an informative talk on the next — really — big thing: The quest to engineer a creature that looks very much like our furry friend, the woolly mammoth. The first step, to sequence the woolly genome, is nearly complete. And it’s huge. (Filmed at TEDxDeExtinction.)
What happens when a dream you've held since childhood … doesn't come true? As Lisa Bu adjusted to a new life in the United States, she turned to books to expand her mind and create a new path for herself. She shares her unique approach to reading in this lovely, personal talk about the magic of books.
What is it like to raise a child who's different from you in some fundamental way (like a prodigy, or a differently abled kid, or a criminal)? In this quietly moving talk, writer Andrew Solomon shares what he learned from talking to dozens of parents — asking them: What's the line between unconditional love and unconditional acceptance?
What's a proven way to lower your energy costs? Would you believe: learning what your neighbor pays. Alex Laskey shows how a quirk of human behavior can make us all better, wiser energy users, with lower bills to prove it.
Journalist Anas Aremeyaw Anas has broken dozens of stories of corruption and organized crime all over Ghana — without ever revealing his identity. In this talk (in which his face remains hidden) Anas shows grisly footage from some of his investigations and demonstrates the importance of facing injustice.
For 28 years, Denise Herzing has spent five months each summer living with a pod of Atlantic spotted dolphins, following three generations of family relationships and behaviors. It's clear they are communicating with one another — but is it language? Could humans use it too? She shares a fascinating new experiment to test this idea.
Filmmaker Martin Villeneuve talks about Mars et Avril, the Canadian sci-fi spectacular he made with virtually no money. In a charming talk, he explains the various ways he overcame financial and logistical constraints to produce his unique and inventive vision of the future.
Economist Andrew McAfee suggests that, yes, probably, droids will take our jobs -- or at least the kinds of jobs we know now. In this far-seeing talk, he thinks through what future jobs might look like, and how to educate coming generations to hold them. Andrew McAfee studies how information technology affects businesses and society.
In a robot lab at TEDGlobal, Raffaello D'Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D'Andrea show drones that play catch, balance and make decisions together -- and watch out for an I-want-this-now demo of Kinect-controlled quads. Roboticist Raffaello D'Andrea explores the possibilities of autonomous technology by collaborating with artists, architects and engineers.
Greece has been the poster child for European economic crisis, but former Prime Minister George Papandreou wonders if it's just a preview of what's to come. “Our democracies," he says, "are trapped by systems that are too big to fail, or more accurately, too big to control” -- while "politicians like me have lost the trust of their peoples." How to solve it? Have citizens re-engage more directly in a new democratic bargain. George Papandreou draws on lessons learned from the Greek debt crisis as he helps guide the EU through difficult waters.
As a novelist, Daniel Suarez spins dystopian tales of the future. But on the TEDGlobal stage, he talks us through a real-life scenario we all need to know more about: the rise of autonomous robotic weapons of war. Advanced drones, automated weapons and AI-powered intelligence-gathering tools, he suggests, could take the decision to make war out of the hands of humans. Daniel Suarez concocts thrilling reads from terrifying (and not-so-farfetched) near-future scenarios.
There's no actual law against women driving in Saudi Arabia. But it's forbidden. Two years ago, Manal al-Sharif decided to encourage women to drive by doing so -- and filming herself for YouTube. Hear her story of what happened next. Manal al-Sharif advocates for women’s right to drive, male guardianship annulment, and family protection in Saudi Arabia.
The 2007-2008 financial crisis, you might think, was an unpredictable one-time crash. But Didier Sornette and his Financial Crisis Observatory have plotted a set of early warning signs for unstable, growing systems, tracking the moment when any bubble is about to pop. (And he's seeing it happen again, right now.) Didier Sornette studies whether it is possible to anticipate big changes or predict crises in complex systems.
Tech communities are booming all over Africa, says Nairobi-based Juliana Rotich, cofounder of the open-source software Ushahidi. But it remains challenging to get and stay connected in a region with frequent blackouts and spotty Internet hookups. So Rotich and friends developed BRCK, offering resilient connectivity for the developing world. Juliana Rotich is the co-founder of Ushahidi, open-source software for collecting and mapping information -- and of iHub, a collective tech space in Nairobi, Kenya. She is a TED Senior Fellow.
A refugee now living in the US, Joseph Kim tells the story of his life in North Korea during the famine years. He's begun to create a new life -- but he still searches for the family he lost. Joseph Kim escaped alone from North Korea at the age of 16, first to China and then to the United States.
In 1985, architect Paul Pholeros was challenged by the director of an Aboriginal-controlled health service to "stop people getting sick" in a small indigenous community in south Australia. The key insights: think beyond medicine and fix the local environment. In this sparky, interactive talk, Pholeros describes projects undertaken by Healthabitat, the organization he now runs to help reduce poverty--through practical design fixes--in Australia and beyond. (Filmed at TEDxSydney.) Paul Pholeros is a director of Healthabitat, a longstanding effort to improve the health of indigenous
Photographer Camille Seaman has been chasing storms for 5 years. In this talk she shows stunning, surreal photos of the heavens in tumult. TED Senior Fellow Camille Seaman photographs big ice and big clouds.
When Lesley Hazleton was writing a biography of Muhammad, she was struck by something: The night he received the revelation of the Koran, according to early accounts, his first reaction was doubt, awe, even fear. And yet this experience became the bedrock of his belief. Hazleton calls for a new appreciation of doubt and questioning as the foundation of faith -- and an end to fundamentalism of all kinds. Writer Lesley Hazleton is the author of 'The First Muslim,' a new look at the life of Muhammad.
As a young surgeon, Peter Attia felt contempt for a patient with diabetes. She was overweight, he thought, and thus responsible for the fact that she needed a foot amputation. But years later, Attia received an unpleasant medical surprise that led him to wonder: is our understanding of diabetes right? Could the precursors to diabetes cause obesity, and not the other way around? A look at how assumptions may be leading us to wage the wrong medical war. Both a surgeon and a self-experimenter, Peter Attia hopes to ease the diabetes epidemic by challenging what we think we know and improving the scientific rigor in nutrition and obesity research.
The New Yorker receives around 1,000 cartoons each week; it only publishes about 17 of them. In this hilarious, fast-paced, and insightful talk, the magazine's longstanding cartoon editor and self-proclaimed "humor analyst" Bob Mankoff dissects the comedy within just some of the "idea drawings" featured in the magazine, explaining what works, what doesn't, and why. Bob Mankoff is the cartoon editor of The New Yorker, as well as an accomplished cartoonist in his own right.
The gastric brooding frog lays its eggs just like any other frog -- then swallows them whole to incubate. That is, it did until it went extinct 30 years ago. Paleontologist Michael Archer makes a case to bring back the gastric brooding frog and the thylacine, commonly known as the Tasmanian tiger. (Filmed at TEDxDeExtinction.) Paleontologist Michael Archer is working to bring back his favorite extinct animal: the Tasmanian tiger.
Scaremongers play on the idea that robots will simply replace people on the job. In fact, they can become our essential collaborators, freeing us up to spend time on less mundane and mechanical challenges. Rodney Brooks points out how valuable this could be as the number of working-age adults drops and the number of retirees swells. He introduces us to Baxter, the robot with eyes that move and arms that react to touch, which could work alongside an aging population -- and learn to help them at home, too. Rodney Brooks builds robots based on biological principles of movement and reasoning. The goal: a robot who can figure things out.
It's a standard assumption in the West: As a society progresses, it eventually becomes a capitalist, multi-party democracy. Right? Eric X. Li, a Chinese investor and political scientist, begs to differ. In this provocative, boundary-pushing talk, he asks his audience to consider that there's more than one way to run a successful modern nation.
Collecting global health data was an imperfect science: Workers tramped through villages to knock on doors and ask questions, wrote the answers on paper forms, then input the data — and from this gappy information, countries would make huge decisions. Data geek Joel Selanikio talks through the sea change in collecting health data in the past decade — starting with the Palm Pilot and Hotmail, and now moving into the cloud. (Filmed at TEDxAustin.)
The border between our physical world and the digital information surrounding us has been getting thinner and thinner. Designer and engineer Jinha Lee wants to dissolve it altogether. As he demonstrates in this short, gasp-inducing talk, his ideas include a pen that penetrates into a screen to draw 3D models and SpaceTop, a computer desktop prototype that lets you reach through the screen to manipulate digital objects.
All under the age of 16, brothers Jonny, Robbie and Tommy Mizzone are from New Jersey, a US state that's better known for the rock of Bruce Springsteen than the bluegrass of Earl Scruggs. Nonetheless, the siblings began performing bluegrass covers, as well as their own compositions, at a young age. Here, they play three dazzling songs in three different keys, passing the lead back and forth from fiddle to banjo to guitar.
When the son of the president of a desperately poor country starts buying mansions and sportscars on an official monthly salary of $7,000, Charmian Gooch suggests, corruption is probably somewhere in the picture. In a blistering, eye-opening talk (and through several specific examples), she details how global corruption trackers follow the money — to some surprisingly familiar faces.
Building a skyscraper? Forget about steel and concrete, says architect Michael Green, and build it out of … wood. As he details in this intriguing talk, it's not only possible to build safe wooden structures up to 30 stories tall (and, he hopes, higher), it's necessary.
Apes, dolphins and elephants are animals with remarkable communication skills. Could the internet be expanded to include sentient species like them? A new and developing idea from a panel of four great thinkers — dolphin researcher Diana Reiss, musician Peter Gabriel, internet of things visionary Neil Gershenfeld and Vint Cerf, one of the fathers of the internet.
Over 85 percent of all pancreatic cancers are diagnosed late, when someone has less than two percent chance of survival. How could this be? Jack Andraka talks about how he developed a promising early detection test for pancreatic cancer that’s super cheap, effective and non-invasive — all before his 16th birthday.
For some reason, says educator Al Vernacchio, the metaphors for talking about sex in the US all come from baseball — scoring, getting to first base, etc. The problem is, this frames sex as a competition, with a winner and a loser. Instead, he suggests a new metaphor, one that's more about shared pleasure, discussion and agreement, fulfillment and enjoyment. Let's talk about … pizza.
Bernie Krause has been recording wild soundscapes — the wind in the trees, the chirping of birds, the subtle sounds of insect larvae — for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's symphonies, from the grunting of a sea anemone to the sad calls of a beaver in mourning.
You don't need to plan an exotic trip to find creative inspiration. Just look up, says Gavin Pretor-Pinney, founder of the Cloud Appreciation Society. As he shares charming photos of nature's finest aerial architecture, Pretor-Pinney calls for us all to take a step off the digital treadmill, lie back and admire the beauty in the sky above.
More and more people worldwide are living in countries not considered their own. Writer Pico Iyer — who himself has three or four “origins” — meditates on the meaning of home, the joy of traveling and the serenity of standing still.
Once it's created, plastic (almost) never dies. While in 12th grade Miranda Wang and Jeanny Yao went in search of a new bacteria to biodegrade plastic — specifically by breaking down phthalates, a harmful plasticizer. They found an answer surprisingly close to home.
In a highly entertaining performance, beatboxer Tom Thum slings beats, comedy and a mouthful of instrumental impersonations into 11 minutes of creativity and fun that will make you smile. (Filmed at TEDxSydney.)
Philosopher John Searle lays out the case for studying human consciousness — and systematically shoots down some of the common objections to taking it seriously. As we learn more about the brain processes that cause awareness, accepting that consciousness is a biological phenomenon is an important first step. And no, he says, consciousness is not a massive computer simulation. (Filmed at TEDxCERN.)
"I love paper, and I love technology," says physicist and former sheep herder Kate Stone, who's spent the past decade working to unite the two. Her experiments combine regular paper with conductive inks and tiny circuit boards to offer a unique, magical experience. To date, applications include a newspaper embedded with audio and video, posters that display energy usage in real time, and the extremely nifty paper drumkit and set of DJ decks she demonstrates onstage.
Roberto D'Angelo and Francesca Fedeli thought their baby boy Mario was healthy — until at 10 days old, they discovered he'd had a perinatal stroke. With Mario unable to control the left side of his body, they grappled with tough questions: Would he be "normal?” Could he live a full life? The poignant story of parents facing their fears — and how they turned them around.
Currency — the bills and coins you carry in your wallet and in your bank account — is founded on marketing, on the belief that banks and governments are trustworthy. Now, Paul Kemp-Robertson walks us through a new generation of currency, supported by that same marketing … but on behalf of a private brand. From Nike Sweat Points to bottles of Tide (which are finding an unexpected use in illegal markets), meet the non-bank future of currencies.
As a young child, Tania Luna left her home in post-Chernobyl Ukraine to take asylum in the US. And one day, on the floor of the New York homeless shelter where she and her family lived, she found a penny. She has never again felt so rich. A meditation on the bittersweet joys of childhood — and how to hold them in mind.
Designer Bastian Schaefer shows off a speculative design for the future of jet planes, with a skeleton inspired by strong, flexible, natural forms and by the needs of the world's, ahem, growing population. Imagine an airplane that's full of light and space — and built up from generative parts in a 3D printer.
As a young EMT on a Jerusalem ambulance, Eli Beer realized that, stuck in brutal urban traffic, they often arrived too late to help. So he organized a group of volunteer EMTs — many on foot — ready to drop everything and dash to save lives in their neighborhood. Today, United Hatzlah uses a smartphone app and a fleet of “ambucycles” to help nearby patients until an ambulance arrives. With an average response time of 3 minutes, last year, they treated 207,000 people in Israel. And the idea is going global.
Showing spectacular clips from productions such as Frida, The Tempest and The Lion King, director Julie Taymor describes a life spent immersed in theater and the movies. Filmed right as controversy over her Broadway production of Spider-Man: Turn Off the Dark was at its peak, she candidly describes the tensions inherent within her creative process, as she strives both to capture the essence of a story—and produce images and experiences unlike anything else.
During a Formula 1 race, a car sends hundreds of millions of data points to its garage for real-time analysis and feedback. So why not use this detailed and rigorous data system elsewhere, like ... at children’s hospitals? Peter van Manen tells us more. (Filmed at TEDxNijmegen.)
Frustrated by not being able to sing two notes at the same time, musical inventor Beardyman built a machine to allow him to create loops and layers from just the sounds he makes with his voice. Given that he can effortlessly conjure the sound of everything from crying babies to buzzing flies, not to mention mimic pretty much any musical instrument imaginable, that's a lot of different sounds. Sit back and let the wall of sound of this dazzling performance wash over you.
Why do we argue? To out-reason our opponents, prove them wrong, and, most of all, to win! ... Right? Philosopher Daniel H. Cohen shows how our most common form of argument — a war in which one person must win and the other must lose — misses out on the real benefits of engaging in active disagreement. (Filmed at TEDxColbyCollege.)
Good design looks great, yes — but why shouldn't it also feel great, smell great and sound great? Designer Jinsop Lee (a TED Talent Search winner) shares his theory of 5-sense design, with a handy graph and a few examples. His hope: to inspire you to notice great multisensory experiences.
From simple alphabets to secret symbolic languages, graphic designer Saki Mafundikwa celebrates the many forms of written communication across the continent of Africa. He highlights the history and legacy that are embodied in written words and symbols, and urges African designers to draw on these graphic forms for fresh inspiration. It's summed up in his favorite Ghanaian glyph, Sankofa, which means "return and get it" — or "learn from the past."
To all appearances, Eleanor Longden was just like every other student, heading to college full of promise and without a care in the world. That was until the voices in her head started talking. Initially innocuous, these internal narrators became increasingly antagonistic and dictatorial, turning her life into a living nightmare. Diagnosed with schizophrenia, hospitalized, drugged, Longden was discarded by a system that didn't know how to help her. Longden tells the moving tale of her years-long journey back to mental health, and makes the case that it was through learning to listen to her voices that she was able to survive.
Born three and a half months prematurely, Derek Paravicini is blind and has severe autism. But with perfect pitch, innate talent and a lot of practice, he became an acclaimed concert pianist by the age of 10. Here, his longtime piano teacher, Adam Ockelford, explains his student’s unique relationship to music, while Paravicini shows how he has ripped up the "Chopsticks" rule book. (Filmed at TEDxWarwick.)
Gayla Benefield was just doing her job — until she uncovered an awful secret about her hometown that meant its mortality rate was 80 times higher than anywhere else in the U.S. But when she tried to tell people about it, she learned an even more shocking truth: People didn’t want to know. In a talk that’s part history lesson, part call-to-action, Margaret Heffernan demonstrates the danger of "willful blindness" and praises ordinary people like Benefield who are willing to speak up. (Filmed at TEDxDanubia.)
Long before sustainability was a buzzword, Pritzker Prize-winning architect Shigeru Ban had begun his experiments with ecologically sound building materials such as cardboard tubes. His remarkable structures are often intended as temporary housing for disaster-struck nations such as Haiti, Rwanda, Japan. Yet often the buildings remain a beloved part of the landscape long after they have served their intended purpose. (Filmed at TEDxTokyo.)
Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health.
Can we edit the content of our memories? It’s a sci-fi-tinged question that Steve Ramirez and Xu Liu are asking in their lab at MIT. Essentially, the pair shoot a laser beam into the brain of a living mouse to activate and manipulate its memory. In this unexpectedly amusing talk they share not only how, but — more importantly — why they do this. (Filmed at TEDxBoston.)
In Lebanon there is one gunshot a year that isn’t part of a scene of routine violence: The opening sound of the Beirut International Marathon. In a moving talk, marathon founder May El-Khalil explains why she believed a 26.2-mile running event could bring together a country divided for decades by politics and religion, even if for one day a year.
They're millions of digits long, and it takes an army of mathematicians and machines to hunt them down — what's not to love about monster primes? Adam Spencer, comedian and lifelong math geek, shares his passion for these odd numbers, and for the mysterious magic of math.
Stress. It makes your heart pound, your breathing quicken and your forehead sweat. But while stress has been made into a public health enemy, new research suggests that stress may only be bad for you if you believe that to be the case. Psychologist Kelly McGonigal urges us to see stress as a positive, and introduces us to an unsung mechanism for stress reduction: reaching out to others.
Technology is advancing in leaps and bounds — and so is economic inequality, says writer Chrystia Freeland. In an impassioned talk, she charts the rise of a new class of plutocrats (those who are extremely powerful because they are extremely wealthy), and suggests that globalization and new technology are actually fueling, rather than closing, the global income gap. Freeland lays out three problems with plutocracy … and one glimmer of hope.
Alexa Meade takes an innovative approach to art. Not for her a life of sketching and stretching canvases. Instead, she selects a topic and then paints it—literally. She covers everything in a scene—people, chairs, food, you name it—in a mask of paint that mimics what's below it. In this eye-opening talk Meade shows off photographs of some of the more outlandish results, and shares a new project involving people, paint and milk.
Wolves were once native to the US' Yellowstone National Park — until hunting wiped them out. But when, in 1995, the wolves began to come back (thanks to an aggressive management program), something interesting happened: the rest of the park began to find a new, more healthful balance. In a bold thought experiment, George Monbiot imagines a wilder world in which humans work to restore the complex, lost natural food chains that once surrounded us.
A third of the world watched live as the World Trade Center collapsed on September 11, 2001; a third more heard about it within 24 hours. (Do you remember where you were?) So exhibits at the soon-to-open 9/11 Memorial Museum will reflect the diversity of the world's experiences of that day. In a moving talk, designer Jake Barton gives a peek at some of those installations, as well as several other projects that aim to make the observer an active participant in the exhibit.
Months after he was born, in 1948, Ron McCallum became blind. In this charming, moving talk, he shows how he is able to read — and celebrates the progression of clever tools and adaptive computer technologies that make it possible. With their help, and that of generous volunteers, he's become a lawyer, an academic, and, most of all, a voracious reader. Welcome to the blind reading revolution. (Filmed at TEDxSydney.)
We’ve known how to cure malaria since the 1600s, so why does the disease still kill hundreds of thousands every year? It’s more than just a problem of medicine, says journalist Sonia Shah. A look into the history of malaria reveals three big-picture challenges to its eradication. Photos: Adam Nadel.
Hailed as the greatest pickpocket in the world, Apollo Robbins studies the quirks of human behavior as he steals your watch. In a hilarious demonstration, Robbins samples the buffet of the TEDGlobal 2013 audience, showing how the flaws in our perception make it possible to swipe a wallet and leave it on its owner’s shoulder while they remain clueless.
How do you pick up a malicious online virus, the kind of malware that snoops on your data and taps your bank account? Often, it's through simple things you do each day without thinking twice. James Lyne reminds us that it's not only the NSA that's watching us, but ever-more-sophisticated cybercriminals, who exploit both weak code and trusting human nature.
Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world’s crops. Could this incredible species be holding up a mirror for us?
What do 24,000 ideas look like? Ecologist Eric Berlow and physicist Sean Gourley apply algorithms to the entire archive of TEDx Talks, taking us on a stimulating visual tour to show how ideas connect globally.
By 2050, it will take 100 billion land animals to provide the world's population with meat, dairy, eggs and leather goods. Maintaining this herd will take a huge, potentially unsustainable toll on the planet. What if there were a different way? In this eye-opening talk, tissue engineering advocate Andras Forgacs argues that biofabricating meat and leather is a civilized way to move past killing animals for hamburgers and handbags.
It often seems like federal-level politicians care more about creating gridlock than solving the world's problems. So who's actually getting bold things done? City mayors. So, political theorist Benjamin Barber suggests: Let's give them more control over global policy. Barber shows how these "urban homeboys" are solving pressing problems on their own turf — and maybe in the world.
Psychologist Elizabeth Loftus studies memories. More precisely, she studies false memories, when people either remember things that didn't happen or remember them differently from the way they really were. It's more common than you might think, and Loftus shares some startling stories and statistics — and raises some important ethical questions.
What does real scientific work look like? As neuroscientist Stuart Firestein jokes: It looks a lot less like the scientific method and a lot more like "farting around … in the dark." In this witty talk, Firestein gets to the heart of science as it is really practiced and suggests that we should value what we don’t know — or “high-quality ignorance” — just as much as what we know.
Trust is on the decline, and we need to rebuild it. That’s a commonly heard suggestion for making a better world … but, says philosopher Onora O’Neill, we don’t really understand what we're suggesting. She flips the question, showing us that our three most common ideas about trust are actually misdirected. (Filmed at TEDxHousesofParliament.)
It's called the "Flynn effect" — the fact that each generation scores higher on an IQ test than the generation before it. Are we actually getting smarter, or just thinking differently? In this fast-paced spin through the cognitive history of the 20th century, moral philosopher James Flynn suggests that changes in the way we think have had surprising (and not always positive) consequences.
Kevin Breel didn't look like a depressed kid: team captain, at every party, funny and confident. But he tells the story of the night he realized that — to save his own life — he needed to say four simple words.
It's a classic underdog tale: David, a young shepherd armed only with a sling, beats Goliath, the mighty warrior. The story has transcended its biblical origins to become a common shorthand for unlikely victory. But, asks Malcolm Gladwell, is that really what the David and Goliath story is about?
In Tana Toraja, weddings and births aren’t the social gatherings that knit society together. In this part of Indonesia, big, raucous funerals form the center of social life. Anthropologist Kelli Swazey takes a look at this culture, in which the bodies of dead relatives are cared for even years after they have passed. While it sounds strange to Western sensibilities, she says, this could actually be a truer reflection of the fact that relationships with loved ones don’t simply end when breathing does. (Filmed at TEDMED.)
Amy Webb was having no luck with online dating. The dates she liked didn't write her back, and her own profile attracted crickets (and worse). So, as any fan of data would do: she started making a spreadsheet. Hear the story of how she went on to hack her online dating life — with frustrating, funny and life-changing results.
Swiss artist and photographer Fabian Oefner is on a mission to make eye-catching art from everyday science. In this charming talk, he shows off some recent psychedelic images, including photographs of crystals as they interact with soundwaves. And, in a live demo, he shows what really happens when you mix paint with magnetic liquid—or when you set fire to whiskey.
In 1969, Buzz Aldrin’s historical step onto the moon leapt mankind into an era of technological possibility. The awesome power of technology was to be used to solve all of our big problems. Fast forward to present day, and what's happened? Are mobile apps all we have to show for ourselves? Journalist Jason Pontin looks closely at the challenges we face to using technology effectively ... for problems that really matter.
Why do we turn to nonprofits, NGOs and governments to solve society's biggest problems? Michael Porter admits he's biased, as a business school professor, but he wants you to hear his case for letting business try to solve massive problems like climate change and access to water. Why? Because when business solves a problem, it makes a profit — which lets that solution grow.
In the past three decades, says Michael Sandel, the US has drifted from a market economy to a market society; it's fair to say that an American's experience of shared civic life depends on how much money they have. (Three key examples: access to education, access to justice, political influence.) In a talk and audience discussion, Sandel asks us to think honestly on this question: In our current democracy, is too much for sale?
In this funny and thought-provoking talk, Janette Sadik-Khan, transportation commissioner of New York City, shares projects that have reshaped street life in the 5 boroughs, including pedestrian zones in Times Square, high-performance buses and a 6,000-cycle-strong bike share. Her mantra: Do bold experiments that are cheap to try out.
Iran and Israel: two nations with tense relations that seem existentially at odds. But for all their antagonistic rhetoric, there is a recent hidden history of collaboration, even friendship. In an informative talk, Trita Parsi shows how an unlikely strategic alliance in the past could mean peace in the future for these two feuding countries.
Physician Gary Slutkin spent a decade fighting tuberculosis, cholera and AIDS epidemics in Africa. When he returned to the United States, he thought he'd escape brutal epidemic deaths. But then he began to look more carefully at gun violence, noting that its spread followed the patterns of infectious diseases. A mind-flipping look at a problem that too many communities have accepted as a given. We've reversed the impact of so many diseases, says Slutkin, and we can do the same with violence.
In the 1930s, broadcast radio introduced an entirely new form of storytelling; today, micro-blogging platforms like Twitter are changing the scene again. Andrew Fitzgerald takes a look at the (aptly) short but fascinating history of new forms of creative experimentation in fiction and storytelling.
How do we solve the problem of the suburbs? Urbanist Jeff Speck shows how we can free ourselves from dependence on the car — which he calls "a gas-belching, time-wasting, life-threatening prosthetic device" — by making our cities more walkable and more pleasant for more people.
Amanda Bennett and her husband were passionate and full of life all throughout their lives together -- and up until the final days, too. Bennett gives a sweet yet powerful talk on why, for the loved ones of the dying, having hope for a happy ending shouldn't warrant a diagnosis of "denial." She calls for a more heroic narrative for death -- to match the ones we have in life.
In the center of Caracas, Venezuela, stands the 45-story "Tower of David," an unfinished, abandoned skyscraper. But about eight years ago, people started moving in. Photographer Iwan Baan shows how people build homes in unlikely places, touring us through the family apartments of Torre David, a city on the water in Nigeria, and an underground village in China. Glorious images celebrate humanity's ability to survive and make a home -- anywhere.
The line between public and private has blurred in the past decade, both online and in real life, and Alessandro Acquisti is here to explain what this means and why it matters. In this thought-provoking, slightly chilling talk, he shares details of recent and ongoing research -- including a project that shows how easy it is to match a photograph of a stranger with their sensitive personal information.
How do we decide who we are? Hetain Patel's surprising performance plays with identity, language and accent — and challenges you to think deeper than surface appearances. A delightful meditation on self, with performer Yuyu Rau, and inspired by Bruce Lee.
The big blue buildings of Ikea have sprouted solar panels and wind turbines; inside, shelves are stocked with LED lighting and recycled cotton. Why? Because as Steve Howard puts it: “Sustainability has gone from a nice-to-do to a must-do.” Howard, the chief sustainability officer at the furniture megastore, talks about his quest to sell eco-friendly materials and practices — both internally and to worldwide customers — and lays a challenge for other global giants.
The past decade has seen slow and steady economic growth across the continent of Africa. But economist Charles Robertson has a bold thesis: Africa's about to boom. He talks through a few of the indicators — from rising education levels to expanded global investment (and not just from China) — that lead him to predict rapid growth for a billion people, sooner than you may think.
What is jealousy? What drives it, and why do we secretly love it? No study has ever been able to capture its “loneliness, longevity, grim thrill” — that is, says Parul Sehgal, except for fiction. In an eloquent meditation she scours pages from literature to show how jealousy is not so different from a quest for knowledge.
The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all atomic matter? With wit and charm, Giudice outlines a grim fate — and why we shouldn't start worrying just yet.
When TED Fellow Xavier Vilalta was commissioned to create a multistory shopping mall in Addis Ababa, he panicked. Other centers represented everything he hated about contemporary architecture: wasteful, glass towers requiring tons of energy whose design had absolutely nothing to do with Africa. In this charming talk, Vilalta shows how he champions an alternative approach: to harness nature, reference design tradition and create beautiful, modern, iconic buildings fit for a community.
Why doesn’t the government just get out of the way and let the private sector — the “real revolutionaries” — innovate? It’s rhetoric you hear everywhere, and Mariana Mazzucato wants to dispel it. In an energetic talk, she shows how the state — which many see as a slow, hunkering behemoth — is really one of our most exciting risk-takers and market-shapers.
Biologist Mohamed Hijri brings to light a farming crisis no one is talking about: We are running out of phosphorus, an essential element that's a key component of DNA and the basis of cellular communication. All roads of this crisis lead back to how we farm — with chemical fertilizers chock-full of the element, which plants are not efficient at absorbing. One solution? Perhaps … a microscopic mushroom. (Filmed at TEDxUdeM.)
One year ago, Abha Dawesar was living in blacked-out Manhattan post-Sandy, scrounging for power to connect. As a novelist, she was struck by this metaphor: Have our lives now become fixated on the drive to digitally connect, while we miss out on what's real?
Chernobyl was the site of the world's worst nuclear accident and, for the past 27 years, the area around the plant has been known as the Exclusion Zone. And yet, a community of about 200 people live there — almost all of them elderly women. These proud grandmas defied orders to relocate because their connection to their homeland and to their community are "forces that rival even radiation."
Dong Woo Jang has an unusual after school hobby. Jang, who was 15 when he gave the talk, tells the story of how living in the concrete jungle of Seoul inspired him to build the perfect bow. Watch him demo one of his beautiful hand-crafted archer's bows.
Up to 100,000 people died in drug-related violence in Mexico in the last 6 years. We might think this has nothing to do with us, but in fact we are all complicit, says Yale professor Rodrigo Canales in this unflinching talk that turns conventional wisdom about drug cartels on its head. The carnage is not about faceless, ignorant goons mindlessly killing each other but is rather the result of some seriously sophisticated brand management.
New York City residents produce 11,000 tons of garbage every day. Every day! This astonishing statistic is just one of the reasons Robin Nagle started a research project with the city's Department of Sanitation. She walked the routes, operated mechanical brooms, even drove a garbage truck herself—all so she could answer a simple-sounding but complicated question: who cleans up after us?
A spinal cord injury can sever the communication between your brain and your body, leading to paralysis. Fresh from his lab, Grégoire Courtine shows a new method — combining drugs, electrical stimulation and a robot — that could re-awaken the neural pathways and help the body learn again to move on its own. See how it works, as a paralyzed rat becomes able to run and navigate stairs.
Recent events have highlighted, underlined and bolded the fact that the United States is performing blanket surveillance on any foreigner whose data passes through an American entity — whether they are suspected of wrongdoing or not. This means that, essentially, every international user of the internet is being watched, says Mikko Hypponen. An important rant, wrapped with a plea: to find alternative solutions to using American companies for the world's information needs.
Math is logical, functional and just ... awesome. Mathemagician Arthur Benjamin explores hidden properties of that weird and wonderful set of numbers, the Fibonacci series. (And reminds you that mathematics can be inspiring, too!)
The developed world holds up the ideals of capitalism, democracy and political rights for all. Those in emerging markets often don't have that luxury. In this powerful talk, economist Dambisa Moyo makes the case that the west can't afford to rest on its laurels and imagine others will blindly follow. Instead, a different model, embodied by China, is increasingly appealing. A call for open-minded political and economic cooperation in the name of transforming the world.
What would a city designed for the blind be like? Chris Downey is an architect who went suddenly blind in 2008; he contrasts life in his beloved San Francisco before and after — and shows how the thoughtful designs that enhance his life now might actually make everyone's life better, sighted or not.
For the young and unemployed in the world's big cities, dreams of opportunity and wealth do come true — but too often because they're heavily recruited by terrorist groups and other violent organizations. Human rights advocate Mohamed Ali draws on stories from his native Mogadishu to make a powerful case for innovation incubators for our cities' young and ambitious.
Different hospitals produce different results on different procedures. Only, patients don’t know that data, making choosing a surgeon a high-stakes guessing game. Stefan Larsson looks at what happens when doctors measure and share their outcomes on hip replacement surgery, for example, to see which techniques are proving the most effective. Could health care get better — and cheaper — if doctors learn from each other in a continuous feedback loop?
What happens when you get an entire audience to stand up and connect with one another? Chaos, that's what. At least, that's what happened when Jane McGonigal tried to teach TED to play her favorite game. Then again, when the game is "massively multiplayer thumb-wrestling," what else would you expect?
Ecologist Lian Pin Koh makes a persuasive case for using drones to protect the world's forests and wildlife. These lightweight autonomous flying vehicles can track animals in their natural habitat, monitor the health of rainforests, even combat crime by detecting poachers via thermal imaging. Added bonus? They're also entirely affordable.
What are our forests really made of? From the air, ecologist Greg Asner uses a spectrometer and high-powered lasers to map nature in meticulous kaleidoscopic 3D detail — what he calls “a very high-tech accounting system” of carbon. In this fascinating talk, Asner gives a clear message: To save our ecosystems, we need more data, gathered in new ways.
Paralyzed by a stroke, Henry Evans uses a telepresence robot to take the stage — and show how new robotics, tweaked and personalized by a group called Robots for Humanity, help him live his life. He shows off a nimble little quadrotor drone, created by a team led by Chad Jenkins, that gives him the ability to navigate space — to once again look around a garden, stroll a campus … (Filmed at TEDxMidAtlantic.)
A billion people in the world lack access to all-season roads. Could the structure of the internet provide a model for how to reach them? Andreas Raptopoulos of Matternet thinks so. He introduces a new type of transportation system that uses electric autonomous flying machines to deliver medicine, food, goods and supplies wherever they are needed.
"Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it." In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance — and limitations — of your "working memory," that part of the brain that allows us to make sense of what's happening right now.
There's an irony behind the latest efforts to extend human life: It's no picnic to be an old person in a youth-oriented society. Older people can become isolated, lacking meaningful work and low on funds. In this intriguing talk, Jared Diamond looks at how many different societies treat their elders — some better, some worse — and suggests we all take advantage of experience.
The human brain is puzzling — it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her detective's cap and leads us through this mystery. By making "brain soup," she arrives at a startling conclusion.
The one thing all humans have in common is that each of us wants to be happy, says Brother David Steindl-Rast, a monk and interfaith scholar. And happiness, he suggests, is born from gratitude. An inspiring lesson in slowing down, looking where you’re going, and above all, being grateful.
Here's a stat worth knowing: In the UK, 63% of men who finish short-term prison sentences are back inside within a year for another crime. Helping them stay outside involves job training, classes, therapy. And it would pay off handsomely — but the government can't find the funds. Toby Eccles shares an imaginative idea for how to change that: the Social Impact Bond. It's an unusual bond that helps fund initiatives with a social goal through private money — with the government paying back the investors (with interest) if the initiatives work.
It's relatively easy to imagine a new medicine, a better cure for some disease. The hard part, though, is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications — even custom cures for one specific person. (Filmed at TEDxBoston)
It's time for liberals and conservatives to transcend their political differences and really listen to each other, says political pundit Sally Kohn. In this optimistic talk, Kohn shares what she learned as a progressive lesbian talking head on Fox News. It’s not about political correctness, she says, but rather, emotional correctness. (Contains profanity.)
David Lang is a maker who taught himself to become an amateur oceanographer — or, he taught a robot to be one for him. In a charming talk Lang, a TED Fellow, shows how he and a network of ocean lovers teamed up to build open-sourced, low-cost underwater explorers.
"An advanced city is not one where even the poor use cars, but rather one where even the rich use public transport," argues Enrique Peñalosa. In this spirited talk, the former mayor of Bogotá shares some of the tactics he used to change the transportation dynamic in the Colombian capital... and suggests ways to think about building smart cities of the future.
"In the cathedral of the wild, we get to see the best parts of ourselves reflected back to us." Boyd Varty, a wildlife activist, shares stories of animals, humans and their interrelatedness, or "ubuntu" — defined as, "I am, because of you." And he dedicates the talk to South African leader Nelson Mandela, the human embodiment of that same great-hearted, generous spirit.
Diébédo Francis Kéré knew exactly what he wanted to do when he got his degree in architecture… He wanted to go home to Gando in Burkina Faso, to help his neighbors reap the benefit of his education. In this charming talk, Kéré shows off some of the beautiful structures he's helped to build in his small village in the years since then, including an award-winning primary school made from clay by the entire community.
Snow Dragon. Pure Imagination. Frozen Minotaur. These are the names Eddy Cartaya and his climbing partner Brent McGregor gave three glacier caves that they were the first to explore. As the Sandy Glacier slowly slides down Mount Hood in Oregon, the caves and tunnels inside it morph annually thanks to warm water from above and warm air from below. At TEDYouth, Cartaya takes us inside these magical spaces where the ice glows in bright blues and greens, and where artifacts rain from the ceiling.
Philosopher Stephen Cave begins with a dark but compelling question: When did you first realize you were going to die? And even more interesting: Why do we humans so often resist the inevitability of death? Cave explores four narratives — common across civilizations — that we tell ourselves "in order to help us manage the terror of death."
Almost everything we own and use, at some point, travels to us by container ship, through a vast network of ocean routes and ports that most of us know almost nothing about. Journalist Rose George tours us through the world of shipping, the underpinning of consumer civilization.
Once the powerhouse of America's industrial might, Detroit is more recently known in the popular imagination as a fabulous ruin, crumbling and bankrupt. But city planner Toni Griffin asks us to look again — and to imagine an entrepreneurial future for the city's 700,000 residents.
Everyone's talking about the "Internet of Things," but what exactly does that mean for our future? In this thoughtful talk, economist Marco Annunziata looks at how technology is transforming the industrial sector, creating machines that can see, feel, sense and react — so they can be operated far more efficiently. Think: airplane parts that send an alert when they need to be serviced, or wind turbines that communicate with one another to generate more electricity. It's a future with exciting implications for us all.
"The opposite of depression is not happiness, but vitality, and it was vitality that seemed to seep away from me in that moment." In a talk equal parts eloquent and devastating, writer Andrew Solomon takes you to the darkest corners of his mind during the years he battled depression. That led him to an eye-opening journey across the world to interview others with depression — only to discover that, to his surprise, the more he talked, the more people wanted to tell their own stories. (Filmed at TEDxMet.)
We've made incredible advances in technology in recent years, but too often it seems only certain fortunate people can benefit. Engineer Krista Donaldson introduces the ReMotion knee, a prosthetic device for above-knee amputees, many of whom earn less than $4 a day. The design contains best-in-class technology and yet is far cheaper than other prosthetics on the market.
It's amazing what a rigged game of Monopoly can reveal. In this entertaining but sobering talk, social psychologist Paul Piff shares his research into how people behave when they feel wealthy. (Hint: badly.) But while the problem of inequality is a complex and daunting challenge, there's good news too. (Filmed at TEDxMarin.)
In the pitch-black night, stung by jellyfish, choking on salt water, singing to herself, hallucinating … Diana Nyad just kept on swimming. And that's how she finally achieved her lifetime goal as an athlete: an extreme 100-mile swim from Cuba to Florida — at age 64. Hear her story.
An epidemic of bad, inefficient, overcrowded meetings is plaguing the world’s businesses — and making workers miserable. David Grady has some ideas on how to stop it. TED@State Street Boston, Oct 2013
Oklahoma City is a midsized town that had a big problem: It was among the most obese towns in America. Mayor Mick Cornett realized that, to make his city a great place to work and live, it had to become healthier too. In this charming talk, he walks us through the interlocking changes that helped OKC drop a collective million pounds (450,000 kilos).
"I have cerebral palsy. I shake all the time," Maysoon Zayid announces at the beginning of this exhilarating, hilarious talk. (Really, it's hilarious.) "I'm like Shakira meets Muhammad Ali." With grace and wit, the Arab-American comedian takes us on a whistle-stop tour of her adventures as an actress, stand-up comic, philanthropist and advocate for the disabled.
More and more, English is a global language; speaking it is perceived as a sign of being modern. But — what do we lose when we leave behind our mother tongues? Suzanne Talhouk makes an impassioned case to love your own language, and to cherish what it can express that no other language can. In Arabic with subtitles. (Filmed at TEDxBeirut.)
Believe it or not, about 20 years' worth of potentially life-saving drugs are sitting in labs right now, untested. Why? Because they can't get the funding to go to trials; the financial risk is too high. Roger Stein is a finance guy, and he thinks deeply about mitigating risk. He and some colleagues at MIT came up with a promising new financial model that could move hundreds of drugs into the testing pipeline. (Filmed at TED@StateStreet.)
In the US, 80% of girls have been on a diet by the time they're 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn't work, but is likely to do more harm than good. She suggests ideas for how to live a less diet-obsessed life, intuitively.
Imagine if you could surf Facebook ... from the Middle Ages. Well, it may not be as far off as it sounds. In a fun and interesting talk, researcher and engineer Frederic Kaplan shows off the Venice Time Machine, a project to digitize 80 kilometers of books to create a historical and geographical simulation of Venice across 1000 years. (Filmed at TEDxCaFoscariU.)
The music industry has sometimes struggled to find its feet in the digital world. In this lovely talk, TED Fellow Ryan Holladay tells us why he is experimenting with what he describes as "location-aware music." This programming and musical feat involves hundreds of geotagged segments of sounds that only play when a listener is physically nearby. (Filmed at TED@BCG.)
You might not expect the chief operating officer of a major global corporation to look too far beyond either the balance sheet or the bottom line. But Harish Manwani, COO of Unilever, makes a passionate argument that doing so to include value, purpose and sustainability in top-level decision-making is not just savvy, it's the only way to run a 21st century business responsibly.
One hundred sixty years after the invention of the needle and syringe, we’re still using them to deliver vaccines; it’s time to evolve. Biomedical engineer Mark Kendall demos the Nanopatch, a one-centimeter-by-one-centimeter square vaccine that can be applied painlessly to the skin. He shows how this tiny piece of silicon can overcome four major shortcomings of the modern needle and syringe, at a fraction of the cost.
Sheryl Sandberg admits she was terrified to step onto the TED stage in 2010 — because she was going to talk, for the first time, about the lonely experience of being a woman in the top tiers of business. Millions of views (and a best-selling book) later, the Facebook COO talks with the woman who pushed her to give that first talk, Pat Mitchell. Sandberg opens up about the reaction to her idea, and explores the ways that women still struggle with success.
Luke Syson was a curator of Renaissance art, of transcendent paintings of saints and solemn Italian ladies — serious art. And then he changed jobs, and inherited the Met's collection of ceramics — pretty, frilly, "useless" candlesticks and vases. He didn't like it. He didn't get it. Until one day … (Filmed at TEDxMet.)
What kind of robots does an animator / jazz musician / roboticist make? Playful, reactive, curious ones. Guy Hoffman shows demo film of his family of unusual robots — including two musical bots that like to jam with humans.
“If you really want to know a people, start by looking inside their bedrooms," says Shereen El Feki, who traveled through the Middle East for five years, talking to people about sex. While those conversations reflected rigid norms and deep repression, El Feki also discovered that sexual conservatism in the Arab world is a relatively new thing. She wonders: could a re-emergence of public dialogue lead to more satisfying, and safer, sex lives?
Every cell in the human body has a sex, which means that men and women are different right down to the cellular level. Yet too often, research and medicine ignore this insight — and the often startlingly different ways in which the two sexes respond to disease or treatment. As pioneering doctor Paula Johnson describes in this thought-provoking talk, lumping everyone in together means we essentially leave women's health to chance. It's time to rethink.
Why do people feel so miserable and disengaged at work? Because today's businesses are increasingly and dizzyingly complex — and traditional pillars of management are obsolete, says Yves Morieux. So, he says, it falls to individual employees to navigate the rabbit's warren of interdependencies. In this energetic talk, Morieux offers six rules for "smart simplicity." (Rule One: Understand what your colleagues actually do.)
Humanity's fine-tuned sense of fear served us well as a young species, giving us laser focus to avoid being eaten by competing beasts. But it's less wonderful when that same visceral, body-hijacking sense of fear kicks in in front of 20 folk-music fans at a Tuesday night open-mic. Palms sweat, hands shake, vision blurs, and the brain says RUN: it's stage fright. In this charming, tuneful little talk, Joe Kowan talks about how he conquered it.
2013 was a year of hype for MOOCs (massive open online courses). Great big numbers and great big hopes were followed by some disappointing first results. But the head of edX, Anant Agarwal, makes the case that MOOCs still matter — as a way to share high-level learning widely and supplement (but perhaps not replace) traditional classrooms. Agarwal shares his vision of blended learning, where teachers create the ideal learning experience for 21st century students.
When she became the attorney general of New Jersey in 2007, Anne Milgram quickly discovered a few startling facts: not only did her team not really know who they were putting in jail, but they had no way of understanding if their decisions were actually making the public safer. And so began her ongoing, inspirational quest to bring data analytics and statistical analysis to the US criminal justice system.
McKenna Pope's younger brother loved to cook, but he worried about using an Easy-Bake Oven — because it was a toy for girls. So at age 13, Pope started an online petition for the American toy company Hasbro to change the pink-and-purple color scheme on the classic toy and incorporate boys into its TV marketing. In a heartening talk, Pope makes the case for gender-neutral toys and gives a rousing call to action to all kids who feel powerless.
Animal behavior isn't complicated, but it is complex. Nicolas Perony studies how individual animals — be they Scottish Terriers, bats or meerkats — follow simple rules that, collectively, create larger patterns of behavior. And how this complexity born of simplicity can help them adapt to new circumstances, as they arise.
Maya Penn started her first company when she was 8 years old, and thinks deeply about how to be responsible both to her customers and to the planet. She shares her story — and some animations, and some designs, and some infectious energy — in this charming talk.
When Esta Soler lobbied for a bill outlawing domestic violence in 1984, one politician called it the "Take the Fun Out of Marriage Act." "If only I had Twitter then," she mused. This sweeping, optimistic talk charts 30 years of tactics and technologies — from the Polaroid camera to social media — that led to a 64% drop in domestic violence in the U.S.
We're all familiar with satellite imagery, but what we might not know is that much of it is out of date. That's because satellites are big and expensive, so there aren't that many of them up in space. As he explains in this fascinating talk, Dan Berkenstock and his team came up with a different solution, designing a cheap, lightweight satellite with a radically new approach to photographing what's going on on Earth.
As the world's cities undergo explosive growth, inequality is intensifying. Wealthy neighborhoods and impoverished slums grow side by side, the gap between them widening. In this eye-opening talk, architect Teddy Cruz asks us to rethink urban development from the bottom up. Sharing lessons from the slums of Tijuana, Cruz explores the creative intelligence of the city's residents and offers a fresh perspective on what we can learn from places of scarcity.
Is there an equation for intelligence? Yes. It’s F = T ∇ Sτ. In a fascinating and informative talk, physicist and computer scientist Alex Wissner-Gross explains what in the world that means. (Filmed at TEDxBeaconStreet.)
In this charming talk, artist Aparna Rao shows us her latest work: cool, cartoony sculptures (with neat robotic tricks underneath them) that play with your perception — and crave your attention. Take a few minutes to simply be delighted.
In this thoughtful talk, David Puttnam asks a big question about the media: Does it have a moral imperative to create informed citizens, to support democracy? His solution for ensuring media responsibility is bold, and you might not agree. But it's certainly a question worth asking ... (Filmed at TEDxHousesofParliament.)
Most of us want to do the right thing when it comes to the environment. But things aren’t as simple as opting for the paper bag, says sustainability strategist Leyla Acaroglu. A bold call for us to let go of tightly-held green myths and think bigger in order to create systems and products that ease strain on the planet.
Sustainability is pretty clearly one of the world's most important goals; but what groups can really make environmental progress in leaps and bounds? Chris McKnett makes the case that it's large institutional investors. He shows how strong financial data isn't enough, and reveals why investors need to look at a company's environmental, social and governance structures, too.
Many of those with severe speech disorders use a computerized device to communicate. Yet they choose between only a few voice options. That's why Stephen Hawking has an American accent, and why many people end up with the same voice, often to incongruous effect. Speech scientist Rupal Patel wanted to do something about this, and in this wonderful talk she shares her work to engineer unique voices for the voiceless.
In this delightful talk, philosopher Yann Dall’Aglio explores the universal search for tenderness and connection in a world that's ever more focused on the individual. As it turns out, it's easier than you think. A wise and witty reflection on the state of love in the modern age. (Filmed at TEDxParis.)
What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.
The world is full of leadership programs, but the best way to learn how to lead might be right under your nose. In this clear, candid talk, Roselinde Torres describes 25 years observing truly great leaders at work, and shares the three simple but crucial questions would-be company chiefs need to ask to thrive in the future.
An idea permeates our modern view of relationships: that men and women have always paired off in sexually exclusive relationships. But before the dawn of agriculture, humans may actually have been quite promiscuous. Author Christopher Ryan walks us through the controversial evidence that human beings are sexual omnivores by nature, in hopes that a more nuanced understanding may put an end to discrimination, shame and the kind of unrealistic expectations that kill relationships.
In this touching talk, Ash Beckham offers a fresh approach to empathy and openness. It starts with understanding that everyone, at some point in their life, has experienced hardship. The only way out, says Beckham, is to open the door and step out of your closet.
After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig's disease or ALS). Siddharthan Chandran walks through some new techniques using special stem cells that could allow the damaged brain to rebuild faster.
Hacking is about more than mischief-making or political subversion. As Catherine Bracy describes in this spirited talk, it can be just as much a force for good as it is for evil. She spins through some inspiring civically-minded projects in Honolulu, Oakland and Mexico City — and makes a compelling case that we all have what it takes to get involved.
During the financial crisis, the central banks of the United States, United Kingdom and Japan created $3.7 trillion in order to buy assets and encourage investors to do the same. Michael Metcalfe offers a shocking idea: could these same central banks print money to ensure they stay on track with their goals for global aid? Without risking inflation?
In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe's largest pieces, says the Intel Science Fair award winner, we can learn quite a lot about scientific mysteries in our own world and galaxy.
The way we rate national economies is all wrong, says rating agency reformer Annette Heuser. With mysterious and obscure methods, three private US-based credit rating agencies wield immense power over national economies across the globe, and the outcomes can be catastrophic. But what if there was another way? In this bold talk, Heuser shares her vision for a nonprofit agency that would bring more equality and justice into the mix.
As an expert on cutting-edge digital displays, Mary Lou Jepsen studies how to show our most creative ideas on screens. And as a brain surgery patient herself, she is driven to know more about the neural activity that underlies invention, creativity, thought. She meshes these two passions in a rather mind-blowing talk on two cutting-edge brain studies that might point to a new frontier in understanding how (and what) we think.
What does the future of business look like? In an informative talk, Philip Evans gives a quick primer on two long-standing theories in strategy — and explains why he thinks they are essentially invalid.
Privacy researcher Christopher Soghoian sees the landscape of government surveillance shifting beneath our feet, as an industry grows to support monitoring programs. Through private companies, he says, governments are buying technology with the capacity to break into computers, steal documents and monitor activity — without detection. This TED Fellow gives an unsettling look at what's to come.
Vending machines generally offer up sodas, candy bars and chips. Not so for the one created by TED Fellow Gabe Barcia-Colombo. This artist has dreamed up a DNA Vending Machine, which dispenses extracted human DNA, packaged in a vial along with a collectible photo of the person who gave it. It’s charming and quirky, but points out larger ethical issues that will arise as access to biotechnology increases.
Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn almost anything into a fun, hands-on science experiment.
While working with kids who have trouble speaking, Ajit Narayanan sketched out a way to think about language in pictures, to relate words and concepts in "maps."

Here's a TED first: an animated Socratic dialog! In a time when irrationality seems to rule both politics and culture, has reasoned thinking finally lost its power? Watch as psychologist Steven Pinker is gradually, brilliantly persuaded by philosopher Rebecca Newberger Goldstein that reason is actually the key driver of human moral progress, even if its effect sometimes takes generations to unfold. The dialog was recorded live at TED, and animated, in incredible, often hilarious, detail by Cognitive.
Daniel Reisel studies the brains of criminal psychopaths (and mice). And he asks a big question: Instead of warehousing these criminals, shouldn’t we be using what we know about the brain to help them rehabilitate? Put another way: If the brain can grow new neural pathways after an injury … could we help the brain re-grow morality?
Appearing by telepresence robot, Edward Snowden speaks at TED2014 about surveillance and Internet freedom. The right to data privacy, he suggests, is not a partisan issue, but requires a fundamental rethink of the role of the internet in our lives — and the laws that protect it. "Your rights matter,” he says, "because you never know when you're going to need them." Chris Anderson interviews, with special guest Tim Berners-Lee.
There's an astronaut saying: In space, “there is no problem so bad that you can’t make it worse.” So how do you deal with the complexity, the sheer pressure, of dealing with dangerous and scary situations? Retired colonel Chris Hadfield paints a vivid portrait of how to be prepared for the worst in space (and life) — and it starts with walking into a spider’s web. Watch for a special space-y performance.
Anonymous companies protect corrupt individuals – from notorious drug cartel leaders to nefarious arms dealers – behind a shroud of mystery that makes it almost impossible to find and hold them responsible.

Ever since, he's been searching for a convincing modern-day equivalent to Rome's masterpiece. Stay tuned to the end of the talk for his unexpected suggestion.
We humans set a premium on our own free will and independence ... and yet there's a shadowy influence we might not be considering. As science writer Ed Yong explains in this fascinating, hilarious and disturbing talk, parasites have perfected the art of manipulation to an incredible degree. So are they influencing us? It's more than likely.
When hundreds of thousands of tweets are fired every second, a one-in-a-million chance — including unlikely-sounding scenarios that could harm users — happens about 500 times a day. For Del Harvey, who heads Twitter’s Trust and Safety Team, these odds aren’t good. The security maven spends her days thinking about how to prevent worst-case scenarios while giving voice to people around the globe. With deadpan humor, she offers a window into how she keeps 240 million users safe.
Hugh Herr is building the next generation of bionic limbs, robotic prosthetics inspired by nature's own designs.

In this fiery, deeply personal talk, he calls for all citizens to engage, and offers a heartfelt reminder to never give up hope.
More than 8 million people are crowded together to live in New York City. What makes it possible? In part, it’s the city’s great public spaces — from tiny pocket parks to long waterfront promenades — where people can stroll and play. Amanda Burden helped plan some of the city’s newest public spaces, drawing on her experience as, surprisingly, an animal behaviorist. She shares the unexpected challenges of planning parks people love — and why it's important.
What do rap shows, barbershop banter and Sunday services have in common? As Christopher Emdin says, they all hold the secret magic to enthrall and teach at the same time — and it’s a skill we often don't teach to educators. The science advocate (and cofounder of Science Genius B.A.T.T.L.E.S. with the GZA of the Wu-Tang Clan) offers a vision to make the classroom come alive.
We live in a world of unseeable beauty, so subtle and delicate that it is imperceptible to the human eye. To bring this invisible world to light, filmmaker Louie Schwartzberg bends the boundaries of time and space with high-speed cameras, time lapses and microscopes. At TED2014, he shares highlights from his latest project, a 3D film titled "Mysteries of the Unseen World," which slows down, speeds up, and magnifies the astonishing wonders of nature.
What drove David Sengeh to create a more comfortable prosthetic limb? He grew up in Sierra Leone, and too many of the people he loves are missing limbs after the brutal civil war there. When he noticed that people who had prosthetics weren’t actually wearing them, the TED Fellow set out to discover why — and to solve the problem with his team from the MIT Media Lab.
On January 8, 2011, Congresswoman Gabby Giffords was shot in the head while meeting constituents in her home town of Tucson, Arizona. Her husband, the astronaut Mark Kelly, immediately flew to be by her side. In this emotional conversation with Pat Mitchell, the pair describe their lives both before and after the accident — and describe their views on responsible gun ownership.
Within each of us are two selves, suggests David Brooks in this meditative short talk: the self who craves success, who builds a résumé, and the self who seeks connection, community, love — the values that make for a great eulogy. (Joseph Soloveitchik has called these selves "Adam I" and "Adam II.") Brooks asks: Can we balance these two selves?
The parenting section of the bookstore is overwhelming—it's "a giant, candy-colored monument to our collective panic," as writer Jennifer Senior puts it. Why is parenthood filled with so much anxiety? Because the goal of modern, middle-class parents—to raise happy children—is so elusive. In this honest talk, she offers some kinder and more achievable aims.
Puberty is an awkward time for just about everybody, but for transgender teens it can be a nightmare, as they grow overnight into bodies they aren't comfortable with. In a heartfelt talk, endocrinologist Norman Spack tells a personal story of how he became one of the few doctors in the US to treat minors with hormone replacement therapy. By staving off the effects of puberty, Spack gives trans teens the time they need. (Filmed at TEDxBeaconStreet.)
Astronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them — yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" positioned 50,000 km from a telescope to enable imaging of planets about distant stars. It is, he says, the "coolest possible science."
Pick up a book, magazine or screen, and more than likely you'll come across some typography designed by Matthew Carter. In this charming talk, the man behind typefaces such as Verdana, Georgia and Bell Centennial (designed just for phone books — remember them?), takes us on a spin through a career focused on the very last pixel of each letter of a font.
At her first museum job, art historian Sarah Lewis noticed something important about an artist she was studying: Not every artwork was a total masterpiece. She asks us to consider the role of the almost-failure, the near win, in our own lives. In our pursuit of success and mastery, is it actually our near wins that push us forward?
Our energy future depends on nuclear fusion, says Michel Laberge. The plasma physicist runs a small company with a big idea for a new type of nuclear reactor that could produce clean, cheap energy. His secret recipe? High speeds, scorching temperatures and crushing pressure. In this hopeful talk, he explains how nuclear fusion might be just around the corner.
Hamish Jolly, an ocean swimmer in Australia, wanted a wetsuit that would deter a curious shark from mistaking him for a potential source of nourishment. (Which, statistically, is rare, but certainly a fate worth avoiding.) Working with a team of scientists, he and his friends came up with a fresh approach — not a shark cage, not a suit of chain-mail, but a sleek suit that taps our growing understanding of shark vision.
"The computer is an incredibly powerful means of creative expression," says designer and TED Fellow James Patten. But right now, we interact with computers, mainly, by typing and tapping. In this nifty talk and demo, Patten imagines a more visceral, physical way to bring your thoughts and ideas to life in the digital world, taking the computer interface off the screen and putting it into your hands.
Elizabeth Gilbert was once an "unpublished diner waitress," devastated by rejection letters. And yet, in the wake of the success of 'Eat, Pray, Love,' she found herself identifying strongly with her former self. With beautiful insight, Gilbert reflects on why success can be as disorienting as failure and offers a simple — though hard — way to carry on, regardless of outcomes.
In this factual talk, geneticist Wendy Chung shares what we know about autism spectrum disorder — for example, that autism has multiple, perhaps interlocking, causes. Looking beyond the worry and concern that can surround a diagnosis, Chung and her team look at what we’ve learned through studies, treatments and careful listening.
When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them.
Thirty-nine million people in the world are blind, and the majority lost their sight due to curable and preventable diseases. But how do you test and treat people who live in remote areas, where expensive, bulky eye equipment is hard to come by? TED Fellow Andrew Bastawrous demos a smartphone app and cheap hardware that might help.
You can't understand climate change in pieces, says climate scientist Gavin Schmidt. It's the whole, or it's nothing. In this illuminating talk, he explains how he studies the big picture of climate change with mesmerizing models that illustrate the endlessly complex interactions of small-scale environmental events.
Sarah Jones changes personas with the simplest of wardrobe swaps. In a laugh-out-loud improvisation, she invites 11 "friends" from the future on stage—from a fast-talking Latina to an outspoken police officer—to ask them questions supplied by the TED2014 audience.
The subject of race can be very touchy. As finance executive Mellody Hobson says, it's a "conversational third rail." But, she says, that's exactly why we need to start talking about it. In this engaging, persuasive talk, Hobson makes the case that speaking openly about race — and particularly about diversity in hiring — makes for better businesses and a better society.
Marco Tempest uses charming stagecraft to demo EDI, the multi-purpose robot designed to work very closely with humans. Less a magic trick than an intricately choreographed performance, Tempest shows off the robot’s sensing technology, safety features and strength, and makes the case for a closer human-robot relationship. (Okay, there’s a little magic, too.)
When General Stanley McChrystal started fighting al Qaeda in 2003, information and secrets were the lifeblood of his operations.

In a short but powerful talk McChrystal makes the case for actively sharing knowledge.
Web cartoonist Randall Munroe answers simple what-if questions ("what if you hit a baseball moving at the speed of light?") using math, physics, logic and deadpan humor. In this charming talk, a reader’s question about Google's data warehouse leads Munroe down a circuitous path to a hilariously over-detailed answer — in which, shhh, you might actually learn something.
Sampling isn't about "hijacking nostalgia wholesale," says Mark Ronson. It's about inserting yourself into the narrative of a song while also pushing that story forward. In this mind-blowingly original talk, watch the DJ scramble 15 TED Talks into an audio-visual omelette, and trace the evolution of "La Di Da Di," Doug E. Fresh and Slick Rick's 1984 hit that has been reimagined for every generation since.
William Black is a former bank regulator who’s seen firsthand how banking systems can be used to commit fraud — and how “liar's loans” and other tricky tactics led to the 2008 US banking crisis that threatened the international economy. In this engaging talk, Black, now an academic, reveals the best way to rob a bank — from the inside.
Ecologist Deborah Gordon studies ants wherever she can find them — in the desert, in the tropics, in her kitchen ... In this fascinating talk, she explains her obsession with insects most of us would happily swat away without a second thought. She argues that ant life provides a useful model for learning about many other topics, including disease, technology and the human brain.
For many years Sergeant Kevin Briggs had a dark, unusual, at times strangely rewarding job: He patrolled the southern end of San Francisco’s Golden Gate Bridge, a popular site for suicide attempts. In a sobering, deeply personal talk Briggs shares stories from those he’s spoken — and listened — to standing on the edge of life. He gives a powerful piece of advice to those with loved ones who might be contemplating suicide.
Do our smells make us sexy? Popular science suggests yes — pheromones send chemical signals about sex and attraction from our armpits to potential mates. But, despite what you might have heard, there is no conclusive research confirming that humans have these smell molecules. In this eye-opening talk, zoologist Tristram Wyatt explains the fundamental flaws in current pheromone research, and shares his hope for a future that unlocks the fascinating, potentially life-saving knowledge tied up in our scent.
Beware: Rives has a contagious obsession with 4 a.m. At TED2007, the poet shared what was then a minor fixation with a time that kept popping up everywhere.

A lyrical peek into his Museum of Four in the Morning, which overflows with treasures.
What makes a great leader? Management theorist Simon Sinek suggests, it's someone who makes their employees feel secure, who draws staffers into a circle of trust. But creating trust and safety -- especially in an uneven economy -- means taking on big responsibility.
What's a marine biologist doing talking about world hunger? Well, says Jackie Savitz, fixing the world's oceans might just help to feed the planet's billion hungriest people. In an eye-opening talk, Savitz tells us what’s really going on in our global fisheries right now — it’s not good — and offers smart suggestions of how we can help them heal, while making more food for all.
Writer Andrew Solomon has spent his career telling stories of the hardships of others. Now he turns inward, bringing us into a childhood of adversity, while also spinning tales of the courageous people he's met in the years since.

Chris Kluwe wants to look into the future of sports and think about how technology will help not just players and coaches, but fans. Here the former NFL punter envisions a future in which augmented reality will help people experience sports as if they are directly on the field — and maybe even help them see others in a new light, too.
Wes Moore joined the US Army to pay for college, but the experience became core to who he is. In this heartfelt talk, the paratrooper and captain--who went on to write "The Other Wes Moore--”explains the shock of returning home from Afghanistan. He shares the single phrase he heard from civilians on repeat, and shows why it's just not sufficient. It's a call for all of us to ask veterans to tell their stories -- and listen. www.ted.com/talks/view/id/2008
Civilians don't miss war. But soldiers often do. Journalist Sebastian Junger shares his experience embedded with American soldiers at Restrepo, an outpost in Afghanistan's Korengal Valley that saw heavy combat. Giving a look at the "altered state of mind" that comes with war, he shows how combat gives soldiers an intense experience of connection. In the end, could it actually be "the opposite of war" that soldiers miss? www.ted.com/talks/view/id/1999
In 1902, President Theodore Roosevelt legendarily spared the life of a black bear — and prompted a plush toy craze for so-called "teddy bears." Writer Jon Mooallem digs into this toy story and asks us to consider how the tales we tell about wild animals have real consequences for a species' chance of survival — and the natural world at large.
As a young girl, photojournalist and TED Fellow Kitra Cahana dreamed about running away from home to live freely on the road. Now as an adult and self-proclaimed vagabond, she follows modern nomads into their homes — boxcars, bus stops, parking lots, rest stop bathrooms — giving a glimpse into a culture on the margins.
What can we learn from people with the genetics to get sick — who don’t? With most inherited diseases, only some family members will develop the disease, while others who carry the same genetic risks dodge it. Stephen Friend suggests we start studying those family members who stay healthy. Hear about the Resilience Project, a massive effort to collect genetic materials that may help decode inherited disorders.
Sting’s early life was dominated by a shipyard—and he dreamed of nothing more than escaping the industrial drudgery. But after a nasty bout of writer’s block that stretched on for years, Sting found himself channeling the stories of the shipyard workers he knew in his youth for song material. In a lyrical, confessional talk, Sting treats us to songs from his upcoming musical, and to an encore of “Message in a Bottle.”
Two hundred million years ago, our mammal ancestors developed a new brain feature: the neocortex. This stamp-sized piece of tissue (wrapped around a brain the size of a walnut) is the key to what humanity has become. Now, futurist Ray Kurzweil suggests, we should get ready for the next big leap in brain power, as we tap into the computing power in the cloud.
"Human beings are works in progress that mistakenly think they're finished." Dan Gilbert shares recent research on a phenomenon he calls the "end of history illusion," where we somehow imagine that the person we are right now is the person we'll be for the rest of time. Hint: that's not the case.
"We're all going to die — and poems can help us live with that." In a charming and funny talk, literary critic Stephen Burt takes us on a lyrical journey with some of his favorite poets, all the way down to a line break and back up to the human urge to imagine.
How can robots learn to stabilize on rough terrain, walk upside down, do gymnastic maneuvers in air and run into walls without harming themselves? Robert Full takes a look at the incredible body of the cockroach to show what it can teach robotics engineers.
As a member of both the African American and LGBT communities, filmmaker Yoruba Richen is fascinated with the overlaps and tensions between the gay rights and the civil rights movements. She explores how the two struggles intertwine and propel each other forward — and, in an unmissable argument, she dispels a myth about their points of conflict. A powerful reminder that we all have a stake in equality.
Stella Young is a comedian and journalist who happens to go about her day in a wheelchair — a fact that doesn’t, she’d like to make clear, automatically turn her into a noble inspiration to all humanity. In this very funny talk, Young breaks down society's habit of turning disabled people into “inspiration porn.”
The beauty of hackers, says cybersecurity expert Keren Elazari, is that they force us to evolve and improve. Yes, some hackers are bad guys, but many are working to fight government corruption and advocate for our rights. By exposing vulnerabilities, they push the Internet to become stronger and healthier, wielding their power to create a better world.
In 2002, investigative journalist and TED Fellow Will Potter took a break from his regular beat, writing about shootings and murders for the Chicago Tribune. He went to help a local group campaigning against animal testing: "I thought it would be a safe way to do something positive," he says. Instead, he was arrested, and so began his ongoing journey into a world in which peaceful protest is branded as terrorism.
While studying for his PhD in physics, Uri Alon thought he was a failure because all his research paths led to dead ends. But, with the help of improv theater, he came to realize that there could be joy in getting lost. A call for scientists to stop thinking of research as a direct line from question to answer, but as something more creative. It's a message that will resonate, no matter what your field.

Plenty of good things are done in the name of religion, and plenty of bad things too. But what is religion, exactly — is it good or bad, in and of itself? Philosopher Kwame Anthony Appiah offers a generous, surprising view.
One could argue that slang words like ‘hangry,’ ‘defriend’ and ‘adorkable’ fill crucial meaning gaps in the English language, even if they don't appear in the dictionary. After all, who actually decides which words make it into those pages? Language historian Anne Curzan gives a charming look at the humans behind dictionaries, and the choices they make.
Here's a talk that could literally change your life. Which career should I pursue? Should I break up — or get married?! Where should I live? Big decisions like these can be agonizingly difficult. But that's because we think about them the wrong way, says philosopher Ruth Chang. She offers a powerful new framework for shaping who we truly are.
Jamila Lyiscott is a “tri-tongued orator;” in her powerful spoken-word essay “Broken English,” she celebrates — and challenges — the three distinct flavors of English she speaks with her friends, in the classroom and with her parents. As she explores the complicated history and present-day identity that each language represents, she unpacks what it means to be “articulate.”
What must our dogs be thinking when they look at us? Poet Billy Collins imagines the inner lives of two very different companions. It’s a charming short talk, perfect for taking a break and dreaming…
In 1991, Shaka Senghor shot and killed a man. He was, he says, "a drug dealer with a quick temper and a semi-automatic pistol." Jailed for second degree murder, that could very well have been the end of the story. But it wasn't. Instead, it was the beginning of a years-long journey to redemption, one with humbling and sobering lessons for us all.
Lorrie Faith Cranor studied thousands of real passwords to figure out the surprising, very common mistakes that users — and secured sites — make to compromise security. And how, you may ask, did she study thousands of real passwords without compromising the security of any users? That's a story in itself. It's secret data worth knowing, especially if your password is 123456 ...
Many of the world's biggest problems require asking questions of scientists — but why should we believe what they say? Historian of science Naomi Oreskes thinks deeply about our relationship to belief and draws out three problems with common attitudes toward scientific inquiry — and gives her own reasoning for why we ought to trust science.

Biologist Sara Lewis has spent the past 20 years getting to the bottom of the magic and wonder of fireflies. In this charming talk, she tells us how and why the beetles produce their silent sparks, what happens when two fireflies have sex, and why one group of females is known as the firefly vampire. (It's not pretty.) Find out more astonishing facts about fireflies in Lewis' footnotes, below.
It's an unexpected side effect of globalization: problems that once would have stayed local—say, a bank lending out too much money—now have consequences worldwide. But still, countries operate independently, as if alone on the planet. Policy advisor Simon Anholt has dreamed up an unusual scale to get governments thinking outwardly: The Good Country Index. In a riveting and funny talk, he answers the question, "Which country does the most good?" The answer may surprise you (especially if you live in the US or China).
We often think of bias and prejudice as rooted in ignorance. But as psychologist Paul Bloom seeks to show, prejudice is often natural, rational ... even moral. The key, says Bloom, is to understand how our own biases work — so we can take control when they go wrong.
When he was a child, George Takei and his family were forced into an internment camp for Japanese-Americans, as a “security" measure during World War II. 70 years later, Takei looks back at how the camp shaped his surprising, personal definition of patriotism and democracy.
“Remember before the internet?” asks Joi Ito. “Remember when people used to try to predict the future?” In this engaging talk, the head of the MIT Media Lab skips the future predictions and instead shares a new approach to creating in the moment: building quickly and improving constantly, without waiting for permission or for proof that you have the right idea. This kind of bottom-up innovation is seen in the most fascinating, futuristic projects emerging today, and it starts, he says, with being open and alert to what’s going on around you right now. Don’t be a futurist, he suggests: be a now-ist.
MIT Media Lab founder Nicholas Negroponte takes you on a journey through the last 30 years of tech. The consummate predictor highlights interfaces and innovations he foresaw in the 1970s and 1980s that were scoffed at then but are ubiquitous today. And he leaves you with one last (absurd? brilliant?) prediction for the coming 30 years.
We face an endless string of choices, which leads us to feel anxiety, guilt and pangs of inadequacy that we are perhaps making the wrong ones. But philosopher Renata Salecl asks: Could individual choices be distracting us from something bigger—our power as social thinkers? A bold call for us to stop taking personal choice so seriously and focus on the choices we're making collectively.
Karima Bennoune shares four powerful stories of real people fighting against fundamentalism in their own communities — refusing to allow the faith they love to become a tool for crime, attacks and murder. These personal stories humanize one of the most overlooked human-rights struggles in the world.

At the online University of the People, anyone with a high school diploma can take classes toward a degree in business administration or computer science — without standard tuition fees (though exams cost money). Founder Shai Reshef hopes that higher education is changing "from being a privilege for the few to a basic right, affordable and accessible for all."
Facebook’s “like” and “share” buttons are seen 22 billion times a day, making them some of the most-viewed design elements ever created. Margaret Gould Stewart, Facebook’s director of product design, outlines three rules for design at such a massive scale—one so big that the tiniest of tweaks can cause global outrage, but also so large that the subtlest of improvements can positively impact the lives of many.
Tour the deep dark world of the East German state security agency known as Stasi. Uniquely powerful at spying on its citizens, until the fall of the Berlin Wall in 1989 the Stasi masterminded a system of surveillance and psychological pressure that kept the country under control for decades. Hubertus Knabe studies the Stasi — and was spied on by them. He shares stunning details from the fall of a surveillance state, and shows how easy it was for neighbor to turn on neighbor.
3D animation can bring scientific hypotheses to life. Molecular biologist (and TED Fellow) Janet Iwasa introduces a new open-source animation software designed just for scientists.
Megan Washington is one of Australia's premier singer/songwriters. And, since childhood, she has had a stutter. In this bold and personal talk, she reveals how she copes with this speech impediment—from avoiding the letter combination “st” to tricking her brain by changing her words at the last minute to, yes, singing the things she has to say rather than speaking them.
The new breed of high-tech self-monitors (measuring heartrate, sleep, steps per day) might seem targeted at competitive athletes. But Talithia Williams, a statistician, makes a compelling case that all of us should be measuring and recording simple data about our bodies every day — because our own data can reveal much more than even our doctors may know.
Nick Hanauer is a rich guy, an unrepentant capitalist — and he has something to say to his fellow plutocrats: Wake up! Growing inequality is about to push our societies into conditions resembling pre-revolutionary France. Hear his argument about why a dramatic increase in minimum wage could grow the middle class, deliver economic prosperity ... and prevent a revolution.
In the United States, the agencies that govern prisons are often called ‘Department of Corrections.’ And yet, their focus is on containing and controlling inmates. Dan Pacholke, Deputy Secretary for the Washington State Department of Corrections, shares a different vision: of prisons that provide humane living conditions as well as opportunities for meaningful work and learning.
Far too many Americans are illiterate in power — what it is, how it operates and why some people have it. As a result, those few who do understand power wield disproportionate influence over everyone else. “We need to make civics sexy again,” says civics educator Eric Liu. “As sexy as it was during the American Revolution or the Civil Rights Movement.”
"We spend so much time listening to the things people are saying that we rarely pay attention to the things they don't," says poet and teacher Clint Smith. A short, powerful piece from the heart, about finding the courage to speak up against ignorance and injustice.
Sir Tim Berners-Lee invented the World Wide Web 25 years ago. So it’s worth a listen when he warns us: There’s a battle ahead. Eroding net neutrality, filter bubbles and centralizing corporate control all threaten the web’s wide-open spaces. It’s up to users to fight for the right to access and openness. The question is, What kind of Internet do we want?
The Fez River winds through the medina of Fez, Morocco—a mazelike medieval city that’s a World Heritage site. Once considered the “soul” of this celebrated city, the river succumbed to sewage and pollution, and in the 1950s was covered over bit by bit until nothing remained. TED Fellow Aziza Chaouni recounts her 20 year effort to restore this river to its former glory, and to transform her city in the process.
Children’s book author Jarrett Krosoczka shares the origins of the Lunch Lady graphic novel series, in which undercover school heroes serve lunch…and justice! His new project, School Lunch Hero Day, reveals how cafeteria lunch staff provide more than food, and illustrates how powerful a thank you can be.
Behind those funny animal videos, sometimes, are oddly human-like problems. Laurel Braitman studies non-human animals who exhibit signs of mental health issues — from compulsive bears to self-destructive rats to monkeys with unlikely friends. Braitman asks what we as humans can learn from watching animals cope with depression, sadness and other all-too-human problems.
Ziyah Gafić photographs everyday objects—watches, shoes, glasses. But these images are deceptively simple; the items in them have been exhumed from the mass graves of the Bosnian War. Gafić, a TED Fellow and Sarajevo native, is photographing every item from these graves in order to create a living archive of the identities of those lost.
A post-apocalyptic Earth, emptied of humans, seems like the stuff of science fiction TV and movies. But in this short, surprising talk, Lord Martin Rees asks us to think about our real existential risks — natural and human-made threats that could wipe out humanity. As a concerned member of the human race, he asks: What’s the worst thing that could possibly happen?
Across sub-Saharan Africa, small farmers are the bedrock of national and regional economies—unless the weather proves unpredictable and their crops fail. The solution is insurance, at a vast, continental scale, and at a very low, affordable cost. Rose Goslinga and the Syngenta Foundation for Sustainable Agriculture pioneered an unconventional way to give farmers whose crops fail early a second chance at a growing season.
This talk begins with a personal story of sexual violence that may be difficult to listen to. But that’s the point, says citizen journalist Meera Vijayann: Speaking out on tough, taboo topics is the spark for change. Vijayann uses digital media to speak honestly about her experience of gender violence in her home country of India — and calls on others to speak out too.
Doesn't it seem like a lot of online news sites have moved beyond reporting the news to openly inciting your outrage (and your page views)? News analyst Sally Kohn suggests — don't engage with news that looks like it just wants to make you mad. Instead, give your precious clicks to the news sites you truly trust.
Which of the following is awesome: your lunch or the Great Pyramid of Giza? Comedian Jill Shargaa sounds a hilarious call for us to save the word "awesome" for things that truly inspire awe.
Why is there something instead of nothing? In other words: Why does the universe exist (and why are we in it)? Philosopher and writer Jim Holt follows this question toward three possible answers. Or four. Or none.
Author Isabel Allende is 71. Yes, she has a few wrinkles—but she has incredible perspective too. In this candid talk, meant for viewers of all ages, she talks about her fears as she gets older and shares how she plans to keep on living passionately.
A forest planted by humans, then left to nature’s own devices, typically takes at least 100 years to mature. But what if we could make the process happen ten times faster? In this short talk, eco-entrepreneur (and TED Fellow) Shubhendu Sharma explains how to create a mini-forest ecosystem anywhere.
Colin Grant has spent a lifetime navigating the emotional landscape between his father’s world and his own. Born in England to Jamaican parents, Grant draws on stories of shared experience within his immigrant community — and reflects on how he found forgiveness for a father who rejected him.
If you’re raised on dogma and hate, can you choose a different path? Zak Ebrahim was just seven years old when his father helped plan the 1993 World Trade Center bombing. His story is shocking, powerful and, ultimately, inspiring.
Dan Barasch and James Ramsey have a crazy plan — to create a park, filled with greenery, underneath New York City. The two are developing the Lowline, an underground greenspace the size of a football field. They're building it in a trolley terminal abandoned in 1948, using technology that harvests sunlight above-ground and directs it down below. It's a park that can thrive, even in winter.
How much do you know about the world? Hans Rosling, with his famous charts of global population, health and income data (and an extra-extra-long pointer), demonstrates that you have a high statistical chance of being quite wrong about what you think you know. Play along with his audience quiz — then, from Hans’ son Ola, learn 4 ways to quickly get less ignorant.
Artist Uldus Bakhtiozina uses photographs to poke fun at societal norms in her native Russia. A glimpse into Russian youth culture and a short, fun reminder not to take ourselves too seriously.
Rishi Manchanda has worked as a doctor in South Central Los Angeles for a decade, where he’s come to realize: His job isn’t just about treating a patient’s symptoms, but about getting to the root cause of what is making them ill—the “upstream" factors like a poor diet, a stressful job, a lack of fresh air. It’s a powerful call for doctors to pay attention to a patient's life outside the exam room.
Big Data is everywhere — even the skies. In an informative talk, astronomer Andrew Connolly shows how large amounts of data are being collected about our universe, recording it in its ever-changing moods. Just how do scientists capture so many images at scale? It starts with a giant telescope …
Childhood is surreal. Why shouldn't children's books be? In this whimsical talk, award-winning author Mac Barnett speaks about writing that escapes the page, art as a doorway to wonder — and what real kids say to a fictional whale.
Just like his beloved grandfather, Avi Reichental is a maker of things. The difference is, now he can use 3D printers to make almost anything, out of almost any material. Reichental tours us through the possibilities of 3D printing, for everything from printed candy to highly custom sneakers.
The Amazon River is like a heart, pumping water from the seas through it, and up into the atmosphere through 600 billion trees, which act like lungs. Clouds form, rain falls and the forest thrives. In a lyrical talk, Antonio Donato Nobre talks us through the interconnected systems of this region, and how they provide environmental services to the entire world. A parable for the extraordinary symphony that is nature.
How can we begin to address the global, insidious problem of climate change — a problem that’s too big for any one country to solve? Economist Nicholas Stern lays out a plan, presented to the UN’s Climate Summit in 2014, showing how the world’s countries can work together on climate. It’s a big vision for cooperation, with a payoff that goes far beyond averting disaster. He asks: How can we use this crisis to spur better lives for all?

In 1967, Moshe Safdie reimagined the monolithic apartment building, creating “Habitat ’67,” which gave each unit an unprecedented sense of openness. Nearly 50 years later, he believes the need for this type of building is greater than ever. In this short talk, Safdie surveys a range of projects that do away with the high-rise and let light permeate into densely-packed cities.
Warning: This talk might contain much more than you’d ever want to know about the way the world poops. But as sanitation activist (and TED Fellow) Francis de los Reyes asks — doesn’t everyone deserve a safe place to go?
You’re doing everything right at work, taking all the right advice, but you’re just not moving up. Why? Susan Colantuono shares a simple, surprising piece of advice you might not have heard before quite so plainly. This talk, while aimed at an audience of women, has universal takeaways — for men and women, new grads and midcareer workers.
Big problems need big solutions, sparked by big ideas, imagination and audacity. In this talk, journalist Gail Reed profiles one big solution worth noting: Havana’s Latin American Medical School, which trains global physicians to serve the local communities that need them most.
Brain imaging pioneer Nancy Kanwisher, who uses fMRI scans to see activity in brain regions (often her own), shares what she and her colleagues have learned: The brain is made up of both highly specialized components and general-purpose "machinery." Another surprise: There's so much left to learn.
Pianist Daria van den Bercken fell in love with the baroque keyboard music of George Frideric Handel. Now, she aims to ignite this passion in others. In this talk, she plays us through the emotional roller coaster of his music — while sailing with her piano through the air, driving it down the street, and of course playing on the stage.
French economist Thomas Piketty caused a sensation in early 2014 with his book on a simple, brutal formula explaining economic inequality: r > g (meaning that return on capital is generally higher than economic growth). Here, he talks through the massive data set that led him to conclude: Economic inequality is not new, but it is getting worse, with radical possible impacts.
About 10,000 people a month Google the phrase, “Am I ugly?” Meaghan Ramsey of the Dove Self-Esteem Project has a feeling that many of them are young girls. In a deeply unsettling talk, she walks us through the surprising impacts of low body and image confidence—from lower grade point averages to greater risk-taking with drugs and alcohol. And then shares the key things all of us can do to disrupt this reality.
Pia Mancini and her colleagues want to upgrade democracy in Argentina and beyond. Through their open-source mobile platform they want to bring citizens inside the legislative process, and run candidates who will listen to what they say.
In 2013, international migrants sent $413 billion home to families and friends — three times more than the total of global foreign aid (about $135 billion). This money, known as remittances, makes a significant difference in the lives of those receiving it and plays a major role in the economies of many countries. Economist Dilip Ratha describes the promise of these “dollars wrapped with love” and analyzes how they are stifled by practical and regulatory obstacles.
Glenn Greenwald was one of the first reporters to see — and write about — the Edward Snowden files, with their revelations about the United States' extensive surveillance of private citizens. In this searing talk, Greenwald makes the case for why you need to care about privacy, even if you’re “not doing anything you need to hide."
The brain uses a quarter of the body's entire energy supply, yet only accounts for about two percent of the body's mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.
Myriam Sidibe is a warrior in the fight against childhood disease. Her weapon of choice? A bar of soap. For cost-effective prevention against sickness, it’s hard to beat soapy hand-washing, which cuts down risk of pneumonia, diarrhea, cholera and worse. Sidibe, a public-health expert, makes a smart case for public-private partnerships to promote clean hands — and local, sustainable entrepreneurship.
Along with a crew of technologists and scientists, Jorge Soto is developing a simple, noninvasive, open-source test that looks for early signs of multiple forms of cancer. Onstage at TEDGlobal 2014, he demonstrates a working prototype of the mobile platform for the first time.
50 million people in the world today have been forcefully displaced from their home — a level not seen since WWII. Right now, more than 3 million Syrian refugees are seeking shelter in neighboring countries. In Lebanon, half of these refugees are children; only 20% are in school. Melissa Fleming of the UN's refugee agency calls on all of us to make sure that refugee camps are healing places where people can develop the skills they’ll need to rebuild their hometowns.
In 2011 Ronnie Cahana suffered a severe stroke that left him with locked-in syndrome: completely paralyzed except for his eyes. While this might shatter a normal person’s mental state, Cahana found peace in “dimming down the external chatter,” and “fell in love with life and body anew.” In a somber, emotional talk, his daughter Kitra shares how she documented her father's spiritual experience, as he helped guide others even in a state of seeming helplessness.
Does a set of data make you feel more comfortable? More successful? Then your interpretation of it is likely wrong. In a surprisingly moving talk, Susan Etlinger explains why, as we receive more and more data, we need to deepen our critical thinking skills. Because it's hard to move beyond counting things to really understanding them.
Before he hit eighteen, Fred Swaniker had lived in Ghana, Gambia, Botswana and Zimbabwe. What he learned from a childhood across Africa was that while good leaders can't make much of a difference in societies with strong institutions, in countries with weak structures, leaders could make or break a country. In a passionate talk the entrepreneur and TED Fellow looks at different generations of African leaders and imagines how to develop the leadership of the future.
Technology allows us to give cash directly to the poorest people on the planet. Should we do it? In this thought-provoking talk, veteran aid worker Joy Sun explores two ways to help the poor.
In 1963, Jacques Cousteau lived for 30 days in an underwater laboratory positioned on the floor of the Red Sea, and set a world record in the process. This summer, his grandson Fabien Cousteau broke that record. Cousteau the younger lived for 31 days aboard the Aquarius, an underwater research laboratory nine miles off the coast of Florida. In a charming talk he brings his wondrous adventure to life.
As founder of the Ig Nobel awards, Marc Abrahams explores the world’s most improbable research. In this thought-provoking (and occasionally side-splitting) talk, he tells stories of truly weird science — and makes the case that silliness is critical to boosting public interest in science.
Every human deserves protection under their country’s laws — even when that law is forgotten or ignored. Sharing three cases from her international legal practice, Kimberley Motley, an American litigator practicing in Afghanistan and elsewhere, shows how a country’s own laws can bring both justice and “justness”: using the law for its intended purpose, to protect.
Let's admit it: aerial photo drones and UAVs are a little creepy, and they come with big regulatory and safety problems. But aerial photos can be a powerful way of telling the truth about the world: the size of a protest, the spread of an oil spill, the wildlife hidden in a delta. Sergei Lupashin demos Fotokite, a nifty new way to see the world from on high, safely and under control.
Nature photographer Frans Lanting uses vibrant images to take us deep into the animal world. In this short, visual talk he calls for us to reconnect with other earthly creatures, and to shed the metaphorical skins that separate us from each other.
Debra Jarvis had worked as a hospital chaplain for nearly 30 years when she was diagnosed with cancer. And she learned quite a bit as a patient. In a witty, daring talk, she explains how the identity of “cancer survivor” can feel static. She asks us all to claim our hardest experiences, while giving ourselves room to grow and evolve.
We can see the power of distributed, crowd-sourced business models every day — witness Uber, Kickstarter, Airbnb. But veteran online activist Jeremy Heimans asks: When does that kind of "new power" start to work in politics? His surprising answer: Sooner than you think. It’s a bold argument about the future of politics and power; watch and see if you agree.
Too often, people feel checked out of politics — even at the level of their own city. But urban activist Alessandra Orofino thinks that can change, using a mix of tech and old-fashioned human connection. Sharing examples from her hometown of Rio, she says: "It is up to us to decide whether we want schools or parking lots, recycling projects or construction sites, cars or buses, loneliness or solidarity."
In this intriguing talk, biologist Ameenah Gurib-Fakim introduces us to rare plant species from isolated islands and regions of Africa. Meet the shape-shifting benjoin; the baume de l'ile plate, which might offer a new treatment for asthma; and the iconic baobab tree, which could hold the key to the future of food. Plus: monkey apples.
We all want to use our talents to create something meaningful with our lives. But how to get started? (And ... what if you're shy?) Writer Kare Anderson shares her own story of chronic shyness, and how she opened up her world by helping other people use their own talents and passions.
When asked to build housing for 100 families in Chile ten years ago, Alejandro Aravena looked to an unusual inspiration: the wisdom of favelas and slums. Rather than building a large building with small units, he built flexible half-homes that each family could expand on. It was a complex problem, but with a simple solution — one that he arrived at by working with the families themselves. With a chalkboard and beautiful images of his designs, Aravena walks us through three projects where clever rethinking led to beautiful design with great benefit.
Artists Jeroen Koolhaas and Dre Urhahn create community art by painting entire neighborhoods, and involving those who live there — from the favelas of Rio to the streets of North Philadelphia. What's made their projects succeed? In this funny and inspiring talk, the artists explain their art-first approach — and the importance of a neighborhood barbecue.
Antibiotic drugs save lives. But we simply use them too much — and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will stop working for everyone, as the bacteria they target grow more and more resistant. He calls on all of us (patients and doctors alike) to think of antibiotics — and their ongoing effectiveness — as a finite resource, and to think twice before we tap into it. It’s a sobering look at how global medical trends can strike home.
The term Gross Domestic Product is often talked about as if it were “handed down from god on tablets of stone.” But this concept was invented by an economist in the 1930s. We need a more effective measurement tool to match 21st century needs, says Michael Green: the Social Progress Index. With charm and wit, he shows how this tool measures societies across the three dimensions that actually matter. And reveals the dramatic reordering of nations that occurs when you use it.
Is the War on Drugs doing more harm than good? In a bold talk, drug policy reformist Ethan Nadelmann makes an impassioned plea to end the "backward, heartless, disastrous" movement to stamp out the drug trade. He gives two big reasons we should focus on intelligent regulation instead.
Wouldn’t you want to know if your doctor was a paid spokesman for a drug company? Or held personal beliefs incompatible with the treatment you want? Right now, in the US at least, your doctor simply doesn’t have to tell you about that. And when physician Leana Wen asked her fellow doctors to open up, the reaction she got was … unsettling.
Vincent Moon travels the world with a backpack and a camera, filming astonishing music and ritual the world rarely sees — from a powerful Sufi ritual in Chechnya to an ayahuasca journey in Peru.

Followed by a mesmerizing performance by jazz icon Naná Vasconcelos.
An epidemic of bad, inefficient, overcrowded meetings is plaguing the world’s businesses — and making workers miserable. David Grady has some ideas on how to stop it.
Satellite imaging has revolutionized our knowledge of the Earth, with detailed images of nearly every street corner readily available online. But Planet Labs' Will Marshall says we can do better and go faster — by getting smaller. He introduces his tiny satellites — no bigger than 10 by 10 by 30 centimeters — that, when launched in a cluster, provide high-res images of the entire planet, updated daily.
Remember the Ice Bucket Challenge craze this summer? Meet the mom who started it all. When Nancy Frates's son Pete hurt his wrist in a baseball game, he got an unexpected diagnosis: it wasn’t a broken bone, it was ALS, and there is no cure. In this inspiring talk, Nancy tells the story of what happened next.
Forget stitches — there's a better way to close wounds. In this talk, TED Fellow Joe Landolina talks about his invention — a medical gel that can instantly stop traumatic bleeding without the need to apply pressure. (Contains medical images.)
“People are so afraid of variety that they try to fit everything into a tiny little box with a specific label,” says 16-year-old Rosie King, who is bold, brash and autistic. She wants to know: Why is everyone so worried about being normal? She sounds a clarion call for every kid, parent, teacher and person to celebrate uniqueness. It’s a soaring testament to the potential of human diversity.
"The greatest and most endangered species in the Amazon rainforest is not the jaguar or the harpy eagle," says Mark Plotkin, "It's the isolated and uncontacted tribes." In an energetic and sobering talk, the ethnobotanist brings us into the world of the forest's indigenous tribes and the incredible medicinal plants that their shamans use to heal. He outlines the challenges and perils that are endangering them — and their wisdom — and urges us to protect this irreplaceable repository of knowledge.
Why do some people struggle more than others to keep off the pounds? Social psychologist Emily Balcetis shows research that addresses one of the many factors: Vision. In an informative talk, she shows how when it comes to fitness, some people quite literally see the world differently from others — and offers a surprisingly simple solution to overcome these differences.
The place that travel writer Pico Iyer would most like to go? Nowhere. In a counterintuitive and lyrical meditation, Iyer takes a look at the incredible insight that comes with taking time for stillness. In our world of constant movement and distraction, he teases out strategies we all can use to take back a few minutes out of every day, or a few days out of every season. It’s the talk for anyone who feels overwhelmed by the demands for our world.
To see is to believe, says Oren Yakobovich — which is why he helps everyday people use hidden cameras to film dangerous situations of violence, political fraud and abuse. His organization, Videre, uncovers, verifies and publicizes human-rights abuses that the world needs to witness.
This year, explorer Ben Saunders attempted his most ambitious trek yet. He set out to complete Captain Robert Falcon Scott’s failed 1912 polar expedition — a four-month, 1,800-mile round trip journey from the edge of Antarctica to the South Pole and back. In the first talk given after his adventure, just five weeks after his return, Saunders offers a raw, honest look at this “hubris”-tinged mission that brought him to the most difficult decision of his life.
It sounds counterintuitive, but by 2030, many of the world's largest economies will have more jobs than adult citizens to do those jobs. In this data-filled — and quite charming — talk, human resources expert Rainer Strack suggests that countries ought to look across borders for mobile and willing job seekers. But to do that, they need to start by changing the culture in their businesses.
What do you call a veterinarian who can only take care of one species? A physician. In a fascinating talk, Barbara Natterson-Horowitz shares how a species-spanning approach to health can improve medical care of the human animal — particularly when it comes to mental health.
Choreographer Aakash Odedra is dyslexic and has always felt that his best expression comes through movement. “Murmur” is his ode to that experience, teaming up with co-creators Lewis Major and Ars Electronica Futurelab. Watch him spin his way through the center of a storm, as pages of books take flight all around him.
“In my lifetime, I have never lived one day of peace in my country,” says Jose Miguel Sokoloff. This ad executive from Colombia saw a chance to help guerrilla fighters choose to come home — with smart marketing. He shares how some creative, welcoming messages have helped thousands of guerrillas decide to put down their weapons — and the key insights behind these surprising tactics.
“Men fight wars, and women mourn them,” says documentary photographer Anastasia Taylor-Lind. With stark, arresting images from the Maidan protests in Ukraine, the TED Fellow shows us intimate faces from the revolution. A grim and beautiful talk.
You've heard about slow food. Now here's slow ... TV? In this very funny talk, Norwegian television producer Thomas Hellum shares how he and his team began to broadcast long, boring events, often live — and found a rapt audience. Shows include a 7-hour train journey, an 18-hour fishing expedition and a 5.5-day ferry voyage along the coast of Norway. The results are both beautiful and fascinating. Really.
A very unsexy-sounding piece of technology could mean that the police know where you go, with whom, and when: the automatic license plate reader. These cameras are innocuously placed all across small-town America to catch known criminals, but as lawyer and TED Fellow Catherine Crump shows, the data they collect in aggregate could have disastrous consequences for everyone the world over.
Every city has its neighborhoods, cliques and clubs, the hidden lines that join and divide people in the same town. What can we learn about cities by looking at what people share online? Starting with his own home town of Baltimore, Dave Troy has been visualizing what the tweets of city dwellers reveal about who lives there, who they talk to — and who they don’t.
Our biases can be dangerous, even deadly — as we've seen in the cases of Michael Brown in Ferguson, Missouri, and Eric Garner, in Staten Island, New York. Diversity advocate Vernā Myers looks closely at some of the subconscious attitudes we hold toward out-groups. She makes a plea to all people: Acknowledge your biases. Then move toward, not away from, the groups that make you uncomfortable. In a funny, impassioned, important talk, she shows us how.
What happens when we teach a computer how to learn? Technologist Jeremy Howard shares some surprising new developments in the fast-moving field of deep learning, a technique that can give computers the ability to learn Chinese, or to recognize objects in photos, or to help think through a medical diagnosis. (One deep learning tool, after watching hours of YouTube, taught itself the concept of “cats.”) Get caught up on a field that will change the way the computers around you behave … sooner than you probably think.
Carol Dweck researches “growth mindset” — the idea that we can grow our brain's capacity to learn and to solve problems. In this talk, she describes two ways to think about a problem that’s slightly too hard for you to solve. Are you not smart enough to solve it … or have you just not solved it yet? A great introduction to this influential field.
In 2011, journalist Bruno Torturra covered a protest in São Paulo which turned ugly. His experience of being teargassed had a profound effect on the way he thought about his work, and he quit his job to focus on broadcasting raw, unedited experiences online. In this fascinating talk, he shares some of the ways in which he's experimented with livestreaming on the web, and how in the process he has helped to create a very modern media network.
In Brazil, "catadores" collect junk and recyclables. But while they provide a vital service that benefits all, they are nearly invisible as they roam the streets. Enter graffiti artist Mundano, a TED Fellow. In a spirited talk, he describes his project "Pimp My Carroça," which has transformed these heroic workers' carts into things of beauty and infused them with a sense of humor. It's a movement that is going global.
In this fun, short talk from TEDYouth, lexicographer Erin McKean encourages — nay, cheerleads — her audience to create new words when the existing ones won’t quite do. She lists out 6 ways to make new words in English, from compounding to “verbing,” in order to make language better at expressing what we mean, and to create more ways for us to understand one another.
Meet the “motion microscope,” a video-processing tool that plays up tiny changes in motion and color impossible to see with the naked eye. Video researcher Michael Rubinstein plays us clip after jaw-dropping clip showing how this tech can track an individual’s pulse and heartbeat simply from a piece of footage. Watch him re-create a conversation by amplifying the movements from sound waves bouncing off a bag of chips. The wow-inspiring and sinister applications of this tech you have to see to believe.
Whales have a surprising and important job, says marine biologist Asha de Vos: these massive creatures are ecosystem engineers, keeping the oceans healthy and stable by ... well, by pooping, for a start. Learn from de Vos, a TED Fellow, about the undervalued work that whales do to help maintain the stability and health of our seas — and our planet.
Mapping apps help us find the fastest route to where we’re going. But what if we’d rather wander? Researcher Daniele Quercia demos “happy maps” that take into account not only the route you want to take, but how you want to feel along the way.
Aziz Abu Sarah is a Palestinian activist with an unusual approach to peace-keeping: Be a tourist. The TED Fellow shows how simple interactions with people in different cultures can erode decades of hate. He starts with Palestinians visiting Israelis and moves beyond ...
In Guatemala’s 36-year conflict, 200,000 civilians were killed — and more than 40,000 were never identified. Pioneering forensic anthropologist Fredy Peccerelli and his team use DNA, archeology and storytelling to help families find the bodies of their loved ones. It’s a sobering task, but it can bring peace of mind — and sometimes, justice. (Contains medical imagery.)
"Save the rainforest” is an environmental slogan as old as time — but Tasso Azevedo catches us up on how the fight is actually going these days. Spurred by the jaw-dropping losses of the 1990s, new laws (and transparent data) are helping slow the rate of deforestation in Brazil. Is it enough? Not yet. He has five ideas about what we should do next. And he asks if the lessons learned in Brazil could be applied to an even bigger problem: global climate change.
Navi Radjou has spent years studying "jugaad," also known as frugal innovation. Pioneered by entrepreneurs in emerging markets who figured out how to get spectacular value from limited resources, the practice has now caught on globally. Peppering his talk with a wealth of examples of human ingenuity at work, Radjou also shares three principles for how we can all do more with less.
2041 will be a pivotal year for our planet. That year will mark the end of a 50-year agreement to keep Antarctica, the Earth’s last pristine continent, free of exploitation. Explorer Robert Swan — the first person to walk both the North and South Poles — is on a mission to ensure that we extend that treaty. With passion and vigor, he pleads with us to choose the preservation of the Antarctic for our own survival.
Worldwide, violence is on the decline, but in the crowded cities of the global south — cities like Aleppo, Bamako and Caracas — violence is actually accelerating, fueled by the drug trade, mass unemployment and civil unrest. Security researcher Robert Muggah turns our attention toward these “fragile cities,” super-fast-growing places where infrastructure is weak and government often ineffective. He shows us the four big risks we face, and offers a way to change course.
“It’s said that to be a poet, you have to go to hell and back.” Cristina Domenech teaches writing at an Argentinian prison, and she tells the moving story of helping incarcerated people express themselves, understand themselves — and glory in the freedom of language. Watch for a powerful reading from one of her students, an inmate, in front of an audience of 10,000. In Spanish with subtitles.
What is altruism? Put simply, it's the wish that other people may be happy. And, says Matthieu Ricard, a happiness researcher and a Buddhist monk, altruism is also a great lens for making decisions, both for the short and long term, in work and in life.
By studying the movement and bodies of insects such as ants, Sarah Bergbreiter and her team build incredibly robust, super teeny, mechanical versions of creepy crawlies … and then they add rockets. See their jaw-dropping developments in micro-robotics, and hear about three ways we might use these little helpers in the future.
In rural India, the lack of toilets creates a big, stinking problem. It leads to poor quality water, one of the leading causes of disease in India, and has a disproportionately negative effect on women. Joe Madiath introduces a program to help villagers help themselves, by building clean, protected water and sanitation systems and requiring everyone in the village to collaborate — with significant benefits that ripple across health, education and even government.
Morgana Bailey has been hiding her true self for 16 years. In a brave talk, she utters four words that might not seem like a big deal to some, but to her have been paralyzing. Why speak up? Because she’s realized that her silence has personal, professional and societal consequences. In front of an audience of her co-workers, she reflects on what it means to fear the judgment of others, and how it makes us judge ourselves.
You may remember neuroscientist Miguel Nicolelis — he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What’s he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to "the limit of your imagination."
Severine Autesserre studies the Democratic Republic of Congo, which is in the middle of the deadliest conflict since World War II; it's been called "the largest ongoing humanitarian crisis in the world.” The conflict seems hopelessly, unsolvably large. But her insight from decades of listening and engaging: The conflicts are often locally based. And instead of focusing on solutions that scale to a national level, leaders and aid groups might be better served solving local crises before they ignite.
Khadija Gbla grew up caught between two definitions of what it means to be an “empowered woman.” While her Sierra Leonean mother thought that circumsizing her — and thus stifling her sexual urges — was the ultimate form of empowerment, her culture as a teenager in Australia told her that she deserved pleasure and that what happened to her was called “female genital mutilation.” In a candid and funny talk, she shares what it was like to make her way in a “clitoris-centric society,” and how she works to make sure other women don’t have to figure this out. (Warning: This talk contains hard-to-hear details.)
Bassam Tariq is a blogger, a filmmaker, and a halal butcher — but one thread unites his work: His joy in the diversity, the humanness of our individual experiences. In this charming talk, he shares clips from his film "These Birds Walk" and images from his tour of 30 mosques in 30 days — and reminds us to consider the beautiful complexity within us all.
Today, a single email can launch a worldwide movement. But as sociologist Zeynep Tufekci suggests, even though online activism is easy to grow, it often doesn't last. Why? She compares modern movements — Gezi, Ukraine, Hong Kong — to the civil rights movement of the 1960s, and uncovers a surprising benefit of organizing protest movements the way it happened before Twitter.
“Ebola threatens everything that makes us human,” says Bruce Aylward of the World Health Organization. And when the Ebola epidemic exploded in 2014, it caused a worldwide panic. But humanity can beat Ebola — and Aylward shows four strategies that show how we are succeeding. The fight against Ebola is not yet won, he says, but it can be.
How much of what you think about your brain is actually wrong? In this whistlestop tour of dis-proved science, Ben Ambridge walks through 10 popular ideas about psychology that have been proven wrong — and uncovers a few surprising truths about how our brains really work.

What do you do with an outdated encyclopedia in the information age? With X-Acto knives and an eye for a good remix, artist Brian Dettmer makes beautiful, unexpected sculptures that breathe new life into old books.
Just like us, the monarch butterfly sometimes gets sick thanks to a nasty parasite. But biologist Jaap de Roode noticed something interesting about the butterflies he was studying — infected female butterflies would choose to lay their eggs on a specific kind of plant that helped their offspring avoid getting sick. How do they know to choose this plant? Think of it as “the other butterfly effect” — which could teach us to find new medicines for the treatment of human disease.
What if your job didn’t control your life? Brazilian CEO Ricardo Semler practices a radical form of corporate democracy, rethinking everything from board meetings to how workers report their vacation days (they don’t have to). It’s a vision that rewards the wisdom of workers, promotes work-life balance — and leads to some deep insight on what work, and life, is really all about. Bonus question: What if schools were like this too?
60% of people with dementia wander off, an issue that can prove hugely stressful for both patients and caregivers. In this charming talk, hear how teen inventor Kenneth Shinozuka came up with a novel solution to help his night-wandering grandfather and the aunt who looks after him ... and how he hopes to help others with Alzheimer's.
Finding the right mate is no cakewalk — but is it even mathematically likely? In a charming talk, mathematician Hannah Fry shows patterns in how we look for love, and gives her top three tips (verified by math!) for finding that special someone.
We'll go to the doctor when we feel flu-ish or a nagging pain. So why don’t we see a health professional when we feel emotional pain: guilt, loss, loneliness? Too many of us deal with common psychological-health issues on our own, says Guy Winch. But we don’t have to. He makes a compelling case to practice emotional hygiene — taking care of our emotions, our minds, with the same diligence we take care of our bodies.
Childhood trauma isn’t something you just get over as you grow up. Pediatrician Nadine Burke Harris explains that the repeated stress of abuse, neglect and parents struggling with mental health or substance abuse issues has real, tangible effects on the development of the brain. This unfolds across a lifetime, to the point where those who’ve experienced high levels of trauma are at triple the risk for heart disease and lung cancer. An impassioned plea for pediatric medicine to confront the prevention and treatment of trauma, head-on.
In some parts of the world, half of the women lack basic reading and writing skills. The reasons vary, but in many cases, literacy isn't valued by fathers, husbands, even mothers. Photographer and TED Fellow Laura Boushnak traveled to countries including Yemen, Egypt and Tunisia to highlight brave women — schoolgirls, political activists, 60-year-old moms — who are fighting the statistics.
"We will start inhabiting outer space," says Angelo Vermeulen, crew commander of a NASA-funded Mars simulation. "It might take 50 years or it might take 500 years, but it’s going to happen." In this charming talk, the TED Senior Fellow describes some of his official work to make sure humans are prepared for life in deep space ... and shares a fascinating art project in which he challenged people worldwide to design homes we might live in there.
Fifty-three years ago, James A. White Sr. joined the US Air Force. But as an African American man, he had to go to shocking lengths to find a place for his young family to live nearby. He tells this powerful story about the lived experience of "everyday racism" — and how it echoes today in the way he's had to teach his grandchildren to interact with police.
Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge — and largely unexplored — role in our health. “The three pounds of microbes that you carry around with you might be more important than every single gene you carry around in your genome,” he says. Find out why.
Nearly 1000 "honor" killings are reported in Pakistan each year, murders by a family member for behavior deemed "shameful," such as a relationship outside of marriage. When Khalida Brohi lost a close friend to the practice, she resolved to campaign against it. Yet she met resistance from an unlikely source: the very community she hoped to protect. In this powerful, honest talk, Brohi shares how she took a hard look at her own process, and offers sharp insights for other passionate activists.
How do vaccines prevent disease — even among people too young to get vaccinated? It's a concept called "herd immunity," and it relies on a critical mass of people getting their shots to break the chain of infection. Health researcher Romina Libster shows how herd immunity contained a deadly outbreak of H1N1 in her hometown. (In Spanish with subtitles.)
City agencies have access to a wealth of data and statistics reflecting every part of urban life. But as data analyst Ben Wellington suggests in this entertaining talk, sometimes they just don't know what to do with it. He shows how a combination of unexpected questions and smart data crunching can produce strangely useful insights, and shares tips on how to release large sets of data so that anyone can use them.
Small coincidences. They happen all the time and yet, they pass us by because we are not looking for them. In a delightfully subtle trick, magician Helder Guimarães demonstrates with a deck of cards, a dollar bill and a stuffed giraffe.
Hooray for technology! It makes everything better for everyone!! Right? Well, no. When a new technology, like ebooks or health trackers, is only available to some people, it has unintended consequences for all of us. Jon Gosier, a TED Fellow and tech investor, calls out the idea of "trickle-down techonomics," and shares powerful examples of how new tech can make things actually worse if it's not equally distributed. As he says, "the real innovation is in finding ways to include everyone."
The sounds of the rainforest include: the chirps of birds, the buzz of cicadas, the banter of gibbons. But in the background is the almost-always present sound of a chainsaw, from illegal loggers. Engineer Topher White shares a simple, scalable way to stop this brutal deforestation — that starts with your old cell phone.
Performance poet (and math student) Harry Baker spins a love poem about his favorite kind of numbers — the lonely, love-lorn prime. Stay on for two more lively, inspiring poems from this charming performer.
Sending an email message is like sending a postcard, says scientist Andy Yen in this thought-provoking talk: Anyone can read it. Yet encryption, the technology that protects the privacy of email communication, does exist. It's just that until now it has been difficult to install and a hassle to use. Showing a demo of an email program he designed with colleagues at CERN, Yen argues that encryption can be made simple to the point of becoming the default option, providing true email privacy to all.
Throughout her career in banking Ilona Szabó de Carvalho never imagined she’d someday start a social movement. But living in her native Brazil, which leads the world in homicidal violence, she realized she couldn’t just stand by and watch drugs and guns tear her country apart. Szabó de Carvalho reveals four crucial lessons she learned when she left her cushy job and took a fearless stand against the status quo.
In this short, provocative talk, financier Sangu Delle questions whether microfinance — small loans to small entrepreneurs — is the best way to drive growth in developing countries. "We seem to be fixated on this romanticized idea that every poor person in Africa is an entrepreneur,” he says. "Yet, my work has taught me that most people want jobs.” Delle, a TED Fellow, makes the case for supporting large companies and factories — and clearing away the obstacles to pan-African trade.
"Architecture is not about math or zoning — it's about visceral emotions," says Marc Kushner. In a sweeping — often funny — talk, he zooms through the past thirty years of architecture to show how the public, once disconnected, have become an essential part of the design process. With the help of social media, feedback reaches architects years before a building is even created. The result? Architecture that will do more for us than ever before.
As a teenager, Ismael Nazario was sent to New York’s Rikers Island jail, where he spent 300 days in solitary confinement — all before he was ever convicted of a crime. Now as a prison reform advocate he works to change the culture of American jails and prisons, where young people are frequently subjected to violence beyond imagination. Nazario tells his chilling story and suggests ways to help, rather than harm, teens in jail.
Shimpei Takahashi always dreamed of designing toys. But when he started work as a toy developer, he found that the pressure to use data as a starting point for design quashed his creativity. In this short, funny talk, Takahashi describes how he got his ideas flowing again, and shares a simple game anyone can play to generate new ideas. (In Japanese with English subtitles.)
What's the secret to unlocking the creativity hidden inside your daily work, and giving every great idea a chance? Harvard professor Linda Hill, co-author of "Collective Genius," has studied some of the world's most creative companies to come up with a set of tools and tactics to keep great ideas flowing — from everyone in the company, not just the designated "creatives."
Vincent Cochetel was held hostage for 317 days in 1998, while working for the UN High Commissioner on Refugees in Chechnya. For the first time, he recounts the experience — from what it was like to live in a dark, underground chamber, chained to his bed, to the unexpected conversations he had with his captors. With lyricism and power, he explains why he continues his work today. Since 2000, attacks on humanitarian aid workers have tripled — and he wonders what that rise may signal to the world.
Everybody knows that most women go a little crazy right before they get their period, that their reproductive hormones cause their emotions to fluctuate wildly. Except: There's very little scientific consensus about premenstrual syndrome. Says psychologist Robyn Stein DeLuca, science doesn't agree on the definition, cause, treatment or even existence of PMS. She explores what we know and don't know about it — and why the popular myth has persisted.
As humans, we can perceive less than a ten-trillionth of all light waves. “Our experience of reality,” says neuroscientist David Eagleman, “is constrained by our biology.” He wants to change that. His research into our brain processes has led him to create new interfaces — such as a sensory vest — to take in previously unseen information about the world around us.
What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over ... slowly. Onstage at TED2015, he unveils a bold new technique — inspired, yes, by Terminator 2 — that's 25 to 100 times faster, and creates smooth, strong parts. Could it finally help to fulfill the tremendous promise of 3D printing?
"Public shaming as a blood sport has to stop," says Monica Lewinsky. In 1998, she says, “I was Patient Zero of losing a personal reputation on a global scale almost instantaneously.” Today, the kind of online public shaming she went through has become constant — and can turn deadly. In a brave talk, she takes a hard look at our online culture of humiliation, and asks for a different way.
When a very young child looks at a picture, she can identify simple elements: "cat," "book," "chair." Now, computers are getting smart enough to do that too. What's next?

Hear his vision to take StoryCorps global — and how you can be a part of it by interviewing someone with the StoryCorps app.
Theaster Gates, a potter by training and a social activist by calling, wanted to do something about the sorry state of his neighborhood on the south side of Chicago. So he did, transforming abandoned buildings to create community hubs that connect and inspire those who still live there (and draw in those who don't). In this passionate talk, Gates describes his efforts to build a "miniature Versailles" in Chicago, and he shares his fervent belief that culture can be a catalyst for social transformation in any city, anywhere.

In this short, provocative talk, architect Alison Killing looks at buildings where death and dying happen — cemeteries, hospitals, homes. The way we die is changing, and the way we build for dying ... well, maybe that should too. It's a surprisingly fascinating look at a hidden aspect of our cities, and our lives.
Daniel Kish has been blind since he was 13 months old, but has learned to “see” using a form of echolocation. He clicks his tongue and sends out flashes of sound that bounce off surfaces in the environment and return to him, helping him to construct an understanding of the space around him. In a rousing talk, Kish demonstrates how this works and asks us to let go of our fear of the “dark unknown.”
The former prime minister of Australia, Kevin Rudd is also a longtime student of China, with a unique vantage point to watch its power rise in the past few decades. He asks whether the growing ambition of China will inevitably lead to conflict with other major powers — and suggests another narrative.
Photographer Boniface Mwangi wanted to protest against corruption in his home country of Kenya. So he made a plan: He and some friends would stand up and heckle during a public mass meeting. But when the moment came ... he stood alone. What happened next, he says, showed him who he truly was. As he says, "There are two most powerful days in your life. The day you are born, and the day you discover why." Graphic images.
In 2014, the world avoided a global outbreak of Ebola, thanks to thousands of selfless health workers — plus, frankly, some very good luck. In hindsight, we know what we should have done better. So, now's the time, Bill Gates suggests, to put all our good ideas into practice, from scenario planning to vaccine research to health worker training. As he says, "There's no need to panic ... but we need to get going."

In this fascinating and funny talk, Jansen reveals some of the intricate calculations that went into landing the Philae probe on a comet 500 million kilometers from Earth — and shares some incredible photographs taken along the way.
Photojournalist Barat Ali Batoor was living in Afghanistan — until his risky work forced him to leave the country. But for Batoor, a member of a displaced ethnic group called the Hazara, moving home to Pakistan proved dangerous too. And finding a safer place wasn't as simple as buying a plane ticket. Instead, he was forced to pay a human smuggler, and join the deadly tidal wave of migrants seeking asylum by boat. He documents the harrowing ocean trip with powerful photographs.
How did a young man born into a high caste in India come to free 83,000 children from slavery?

Paul Tudor Jones II loves capitalism. It's a system that has done him very well over the last few decades. Nonetheless, the hedge fund manager and philanthropist is concerned that a laser focus on profits is, as he puts it, "threatening the very underpinnings of society." In this thoughtful, passionate talk, he outlines his planned counter-offensive, which centers on the concept of "justness."
While we like to imagine little green men, it’s far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, a hunt which counterintuitively leads us to the remote lakes of the Andes mountains. This extreme environment — with its thin atmosphere and scorched land — approximates the surface of Mars about 3.5 billion years ago. How microbes adapt to survive here may just show us where to look on Mars — and could help us understand why some microbial pathways lead to civilization while others are a dead end.
Collective compassion has meant an overall decrease in global poverty since the 1980s, says civil rights lawyer Gary Haugen. Yet for all the world's aid money, there's a pervasive hidden problem keeping poverty alive. Haugen reveals the dark underlying cause we must recognize and act on now.
Jedidah Isler first fell in love with the night sky as a little girl. Now she’s an astrophysicist who studies supermassive hyperactive black holes. In a charming talk, she takes us trillions of kilometers from Earth to introduce us to objects that can be 1 to 10 billion times the mass of the sun — and which shoot powerful jet streams of particles in our direction.
Chris Milk uses cutting edge technology to produce astonishing films that delight and enchant. But for Milk, the human story is the driving force behind everything he does. In this short, charming talk, he shows some of his collaborations with musicians including Kanye West and Arcade Fire, and describes his latest, mind-bending experiments with virtual reality. (This talk is part of Pop-Up Magazine's guest-curated session at TED2015!)

In a heartfelt piece, the poet paints the scene of his father's furious and fearful response.
A 50-foot-long carnivore who hunted its prey in rivers 97 million years ago, the spinosaurus is a "dragon from deep time." Paleontologist Nizar Ibrahim and his crew found new fossils, hidden in cliffs of the Moroccan Sahara desert, that are helping us learn more about the first swimming dinosaur — who might also be the largest carnivorous dinosaur of all.
Artificial intelligence is getting smarter by leaps and bounds — within this century, research suggests, a computer AI could be as "smart" as a human being. And then, says Nick Bostrom, it will overtake us: "Machine intelligence is the last invention that humanity will ever need to make." A philosopher and technologist, Bostrom asks us to think hard about the world we're building right now, driven by thinking machines. Will our smart machines help to preserve humanity and our values — or will they have values of their own?
Greg Gage is on a mission to make brain science accessible to all. In this fun, kind of creepy demo, the neuroscientist and TED Senior Fellow uses a simple, inexpensive DIY kit to take away the free will of an audience member. It’s not a parlor trick; it actually works. You have to see it to believe it.
Did you know that you're 30 times more likely to laugh if you're with somebody else than if you're alone? Cognitive neuroscientist Sophie Scott shares this and other surprising facts about laughter in this fast-paced, action-packed and, yes, hilarious dash through the science of the topic.
In the United States, two institutions guide teenagers on the journey to adulthood: college and prison. Sociologist Alice Goffman spent six years in a troubled Philadelphia neighborhood and saw first-hand how teenagers of African-American and Latino backgrounds are funneled down the path to prison — sometimes starting with relatively minor infractions. In an impassioned talk she asks, “Why are we offering only handcuffs and jail time?”
Pamela Ronald studies the genes that make plants more resistant to disease and stress. In an eye-opening talk, she describes her decade-long quest to isolate a gene that allows rice to survive prolonged flooding. She shows how the genetic improvement of seeds saved the Hawaiian papaya crop in the 1990s — and makes the case that modern genetics is sometimes the most effective method to advance sustainable agriculture and enhance food security for our planet’s growing population.
Subtle motion happens around us all the time, including tiny vibrations caused by sound. New technology shows that we can pick up on these vibrations and actually re-create sound and conversations just from a video of a seemingly still object. But now Abe Davis takes it one step further: Watch him demo software that lets anyone interact with these hidden properties, just from a simple video.
Legendary dance choreographer Bill T. Jones and TED Fellows Joshua Roman and Somi didn't know exactly what was going to happen when they took the stage at TED2015. They just knew they wanted to offer the audience an opportunity to witness creative collaboration in action. The result: An improvised piece they call "The Red Circle and the Blue Curtain," so extraordinary it had to be shared ...
Liver cancer is one of the most difficult cancers to detect, but synthetic biologist Tal Danino had a left-field thought: What if we could create a probiotic, edible bacteria that was "programmed" to find liver tumors? His insight exploits something we're just beginning to understand about bacteria: their power of quorum sensing, or doing something together once they reach critical mass. Danino, a TED Fellow, explains how quorum sensing works -- and how clever bacteria working together could someday change cancer treatment.
Singer-songwriter Dawn Landes tells the story of Tori Murden McClure, who dreamed of rowing across the Atlantic in a small boat -- but whose dream was almost capsized by waves the size of a seven-story building. Through video, story and song, Landes imagines the mindset of a woman alone in the midst of the vast ocean. (This talk was part of a session at TED2015 guest-curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
We’ve heard that bees are disappearing. But what is making bee colonies so vulnerable? Photographer Anand Varma raised bees in his backyard — in front of a camera — to get an up close view. This project, for National Geographic, gives a lyrical glimpse into a beehive, and reveals one of the biggest threats to its health, a mite that preys on baby bees in their first 21 days of life. With footage set to music from Rob Moose and the Magik*Magik Orchestra, Varma shows the problem ... and what’s being done to solve it. (This talk was part of a session at TED2015 guest-curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
You've never seen buildings like this. The stunning bamboo homes built by Elora Hardy and her team in Bali twist, curve and surprise at every turn. They defy convention because the bamboo itself is so enigmatic. No two poles of bamboo are alike, so every home, bridge and bathroom is exquisitely unique. In this beautiful, immersive talk, she shares the potential of bamboo, as both a sustainable resource and a spark for the imagination. "We have had to invent our own rules," she says.
Roman Mars is obsessed with flags -- and after you watch this talk, you might be, too. These ubiquitous symbols of civic pride are often designed, well, pretty terribly. But they don't have to be. In this surprising and hilarious talk about vexillology -- the study of flags -- Mars reveals the five basic principles of flag design and shows why he believes they can be applied to just about anything.
The ten women in this chorus have all been sentenced to life in prison. They share a moving song about their experiences — one that reveals their hopes, regrets and fears. "I'm not an angel," sings one, "but I'm not the devil." Filmed at an independent TEDx event inside Muncy State Prison, it's a rare and poignant look inside the world of people imprisoned with no hope of parole. (Note: The prison's Office of Victim Advocacy has ensured that victims were treated fairly and respectfully around this TEDx event.)
The founder of Sirius XM satellite radio, Martine Rothblatt now heads up a drug company that makes life-saving medicines for rare diseases (including one drug that saved her own daughter's life). Meanwhile she is working to preserve the consciousness of the woman she loves in a digital file ... and a companion robot. In an onstage conversation with TED's Chris Anderson, Rothblatt shares her powerful story of love, identity, creativity, and limitless possibility.
You’ve just been injured, and you’re on the way home from an hour of physical therapy. The last thing you want to do on your own is confusing exercises that take too long to show results. TED Fellow Cosmin Mihaiu demos a fun, cheap solution that turns boring physical therapy exercises into a video game with crystal-clear instructions.
Chimpanzees are people too, you know. Ok, not exactly. But lawyer Steven Wise has spent the last 30 years working to change these animals' status from "things" to "persons." It's not a matter of legal semantics; as he describes in this fascinating talk, recognizing that animals like chimps have extraordinary cognitive capabilities and rethinking the way we treat them -- legally -- is no less than a moral duty.
Infidelity is the ultimate betrayal. But does it have to be? Relationship therapist Esther Perel examines why people cheat, and unpacks why affairs are so traumatic: because they threaten our emotional security. In infidelity, she sees something unexpected — an expression of longing and loss. A must-watch for anyone who has ever cheated or been cheated on, or who simply wants a new framework for understanding relationships.
"Anything that is worth pursuing is going to require us to suffer, just a little bit," says surf photographer Chris Burkard, as he explains his obsession with the coldest, choppiest, most isolated beaches on earth. With jawdropping photos and stories of places few humans have ever seen -- much less surfed -- he draws us into his "personal crusade against the mundane."
An architect of the "Boston miracle," Rev. Jeffrey Brown started out as a bewildered young pastor watching his Boston neighborhood fall apart around him, as drugs and gang violence took hold of the kids on the streets. The first step to recovery: Listen to those kids, don't just preach to them, and help them reduce violence in their own neighborhoods. It's a powerful talk about listening to make change.
What do you think when you look at this speaker? Well, think again. (And then again.) In this funny, honest, empathetic talk, Yassmin Abdel-Magied challenges us to look beyond our initial perceptions, and to open doors to new ways of supporting others.
Every star we see in the sky has at least one planet orbiting it, says astronomer Sara Seager. So what do we know about these exoplanets, and how can we find out more? Seager introduces her favorite set of exoplanets and shows new technology that can help collect information about them — and even help us look for exoplanets with life.
When Jimmy Nelson traveled to Siberia to photograph the Chukchi people, elders told him: "You cannot photograph us. You have to wait, you have to wait until you get to know us, you have to wait until you understand us." In this gorgeously photo-filled talk, join Nelson's quest to understand — the world, other people, himself — by making astonishing portraits of the world's vanishing tribes and cultures.
Bill Gross has founded a lot of startups, and incubated many others — and he got curious about why some succeeded and others failed. So he gathered data from hundreds of companies, his own and other people's, and ranked each company on five key factors. He found one factor that stands out from the others — and surprised even him.
How do babies learn so much from so little so quickly? In a fun, experiment-filled talk, cognitive scientist Laura Schulz shows how our young ones make decisions with a surprisingly strong sense of logic, well before they can talk.
As human beings, we get used to "the way things are" really fast. But for designers, the way things are is an opportunity ... Could things be better? How? In this funny, breezy talk, the man behind the iPod and the Nest thermostat shares some of his tips for noticing — and driving — change.
There's an organization responsible for more terrorism plots in the United States than al-Qaeda, al-Shabaab and ISIS combined: The FBI. How? Why? In an eye-opening talk, investigative journalist Trevor Aaronson reveals a disturbing FBI practice that breeds terrorist plots by exploiting Muslim-Americans with mental health problems.
On Linda Cliatt-Wayman’s first day as principal at a failing high school in North Philadelphia, she was determined to lay down the law. But she soon realized the job was more complex than she thought. With palpable passion, she shares the three principles that helped her turn around three schools labeled “low-performing and persistently dangerous.” Her fearless determination to lead — and to love the students, no matter what — is a model for leaders in all fields.
For six months, Suki Kim worked as an English teacher at an elite school for North Korea's future leaders — while writing a book on one of the world's most repressive regimes. As she helped her students grapple with concepts like "truth" and "critical thinking," she came to wonder: Was teaching these students to seek the truth putting them in peril? (This talk was part of a session at TED2015 guest-curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
In this performance, Sarah Jones brings you to the front row of a classroom in the future, as a teacher plugs in different personas from the year 2016 to show their varied perspectives on sex work. As she changes props, Jones embodies an elderly homemaker, a “sex work studies” major, an escort, a nun-turned-prostitute and a guy at a strip club for his bachelor party. It’s an intriguing look at a taboo topic, that flips cultural norms around sex inside out.
Cognitive scientist Donald Hoffman is trying to answer a big question: Do we experience the world as it really is ... or as we need it to be? In this ever so slightly mind-blowing talk, he ponders how our minds construct reality for us.
"I was the mystery of an anatomy, a question asked but not answered," says poet Lee Mokobe, a TED Fellow, in this gripping and poetic exploration of identity and transition. It's a thoughtful reflection on bodies, and the meanings poured into them.
Our emotions influence every aspect of our lives — how we learn, how we communicate, how we make decisions. Yet they’re absent from our digital lives; the devices and apps we interact with have no way of knowing how we feel. Scientist Rana el Kaliouby aims to change that. She demos a powerful new technology that reads your facial expressions and matches them to corresponding emotions. This “emotion engine” has big implications, she says, and could change not just how we interact with machines — but with each other.
Organizations are often run according to “the superchicken model,” where the value is placed on star employees who outperform others. And yet, this isn’t what drives the most high-achieving teams. Business leader Margaret Heffernan observes that it is social cohesion — built every coffee break, every time one team member asks another for help — that leads over time to great results. It's a radical rethink of what drives us to do our best work, and what it means to be a leader. Because as Heffernan points out: “Companies don’t have ideas. Only people do.”
Decades ago, few pediatricians had heard of autism. In 1975, 1 in 5,000 kids was estimated to have it. Today, 1 in 68 is on the autism spectrum. What caused this steep rise? Steve Silberman points to “a perfect storm of autism awareness” — a pair of psychologists with an accepting view, an unexpected pop culture moment and a new clinical test. But to really understand, we have to go back further to an Austrian doctor by the name of Hans Asperger, who published a pioneering paper in 1944. Because it was buried in time, autism has been shrouded in misunderstanding ever since. (This talk was part of a TED2015 session curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
For the last 12 years, LaToya Ruby Frazier has photographed friends, neighbors and family in Braddock, Pennsylvania. But though the steel town has lately been hailed as a posterchild of "rustbelt revitalization," Frazier's pictures tell a different story, of the real impact of inequality and environmental toxicity. In this short, powerful talk, the TED Fellow shares a deeply personal glimpse of an often-unseen world.
Raised listening to his dad's old records, Joey Alexander plays a brand of sharp, modern piano jazz that you likely wouldn't expect to hear from a pre-teenager. Listen as the 11-year-old delights the TED crowd with his very special performance of a Thelonious Monk classic.
When writer Roxane Gay dubbed herself a "bad feminist," she was making a joke, acknowledging that she couldn't possibly live up to the demands for perfection of the feminist movement. But she's realized that the joke rang hollow. In a thoughtful and provocative talk, she asks us to embrace all flavors of feminism — and make the small choices that, en masse, might lead to actual change.
Book designer Chip Kidd knows all too well how often we judge things by first appearances. In this hilarious, fast-paced talk, he explains the two techniques designers use to communicate instantly -- clarity and mystery -- and when, why and how they work. He celebrates beautiful, useful pieces of design, skewers less successful work, and shares the thinking behind some of his own iconic book covers.
Penicillin changed everything. Infections that had previously killed were suddenly quickly curable. Yet as Maryn McKenna shares in this sobering talk, we've squandered the advantages afforded us by that and later antibiotics. Drug-resistant bacteria mean we're entering a post-antibiotic world -- and it won't be pretty. There are, however, things we can do ... if we start right now.
Statistically, the least reliable part of the car is ... the driver. Chris Urmson heads up Google's driverless car program, one of several efforts to remove humans from the driver's seat. He talks about where his program is right now, and shares fascinating footage that shows how the car sees the road and makes autonomous decisions about what to do next.
What do you learn when you sail around the world on your own? When solo sailor Ellen MacArthur circled the globe – carrying everything she needed with her – she came back with new insight into the way the world works, as a place of interlocking cycles and finite resources, where the decisions we make today affect what's left for tomorrow. She proposes a bold new way to see the world's economic systems: not as linear, but as circular, where everything comes around.
With his signature resolve, former US President Jimmy Carter dives into three unexpected reasons why the mistreatment of women and girls continues in so many manifestations in so many parts of the world, both developed and developing. The final reason he gives? “In general, men don’t give a damn.”
For the longest time, doctors basically ignored the most basic and frustrating part of being sick -- pain. In this lyrical, informative talk, Latif Nasser tells the extraordinary story of wrestler and doctor John J. Bonica, who persuaded the medical profession to take pain seriously -- and transformed the lives of millions.
In 2011, the US Armed Forces still had a ban on women in combat -- but in that year, a Special Operations team of women was sent to Afghanistan to serve on the front lines, to build rapport with locals and try to help bring an end to the war. Reporter Gayle Tzemach Lemmon tells the story of this "band of sisters," an extraordinary group of women warriors who helped break a long-standing barrier to serve.
Basketball is a fast-moving game of improvisation, contact and, ahem, spatio-temporal pattern recognition. Rajiv Maheswaran and his colleagues are analyzing the movements behind the key plays of the game, to help coaches and players combine intuition with new data. Bonus: What they're learning could help us understand how humans move everywhere.
Memory Banda’s life took a divergent path from her sister’s. When her sister reached puberty, she was sent to a traditional “initiation camp” that teaches girls “how to sexually please a man.” She got pregnant there — at age 11. Banda, however, refused to go. Instead, she organized others and asked her community’s leader to issue a bylaw that no girl should be forced to marry before turning 18. She pushed on to the national level … with incredible results for girls across Malawi.
What really causes addiction -- to everything from cocaine to smart-phones? And how can we overcome it? Johann Hari has seen our current methods fail firsthand, as he has watched loved ones struggle to manage their addictions. He started to wonder why we treat addicts the way we do -- and if there might be a better way. As he shares in this deeply personal talk, his questions took him around the world, and unearthed some surprising and hopeful ways of thinking about an age-old problem.
Ash Beckham recently found herself in a situation that made her ask: who am I? She felt pulled between two roles — as an aunt and as an advocate. Each of us feels this struggle sometimes, she says -- and offers bold suggestions for how to stand up for your moral integrity when it isn’t convenient.
Behind the everyday bargains we all love -- the $10 manicure, the unlimited shrimp buffet -- is a hidden world of forced labor to keep those prices at rock bottom. Noy Thrupkaew investigates human trafficking – which flourishes in the US and Europe, as well as developing countries – and shows us the human faces behind the exploited labor that feeds global consumers.
Abortion is extremely common. In America, for example, one in three women will have an abortion in their lifetime, yet the strong emotions sparked by the topic -- and the highly politicized rhetoric around it -- leave little room for thoughtful, open debate. In this personal, thoughtful talk, Aspen Baker makes the case for being neither “pro-life” nor “pro-choice” but rather "pro-voice" -- and for the roles that listening and storytelling can play when it comes to discussing difficult topics.
Stacey Baker has always been obsessed with how couples meet. When she asked photographer Alec Soth to help her explore this topic, they found themselves at the world’s largest speed-dating event, held in Las Vegas on Valentine’s Day, and at the largest retirement community in Nevada — with Soth taking portraits of pairs in each locale. Between these two extremes, they unwound a beautiful through-line of how a couple goes from meeting to creating a life together. (This talk was part of a TED2015 session curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
When artist Salvatore Iaconesi was diagnosed with brain cancer, he refused to be a passive patient -- which, he points out, means "one who waits." So he hacked his brain scans, posted them online, and invited a global community to pitch in on a "cure." This sometimes meant medical advice, and it sometimes meant art, music, emotional support -- from more than half a million people.
Marlene Zuk delightedly, determinedly studies insects. In this enlightening, funny talk, she shares just some of the ways that they are truly astonishing -- not least for the creative ways they have sex.
Twitter gives a voice to the voiceless, a way to speak up and hit back at perceived injustice. But sometimes, says Jon Ronson, things go too far. In a jaw-dropping story of how one un-funny tweet ruined a woman's life and career, Ronson shows how online commenters can end up behaving like a baying mob -- and says it's time to rethink how we interact online.
Strong faith is a core part of Alaa Murabit's identity -- but when she moved from Canada to Libya as a young woman, she was surprised how the tenets of Islam were used to severely limit women's rights, independence and ability to lead. She wondered: Was this really religious doctrine? With humor, passion and a refreshingly rebellious spirt, she shares how she found examples of female leaders across the history of her faith — and how she speaks up for women using verses from the Koran.
Some of us learn best in the classroom, and some of us ... well, we don't. But we still love to learn -- we just need to find the way that works for us. In this charming, personal talk, author John Green shares the community of learning that he found in online video.
What does this gorgeous street art say? It's Arabic poetry, inspired by bold graffiti and placed where a message of hope and peace can do the most good. In this quietly passionate talk, artist and TED Fellow eL Seed describes his ambition: to create art so beautiful it needs no translation.
Seventy thousand years ago, our human ancestors were insignificant animals, just minding their own business in a corner of Africa with all the other animals. But now, few would disagree that humans dominate planet Earth; we've spread to every continent, and our actions determine the fate of other animals (and possibly Earth itself). How did we get from there to here? Historian Yuval Noah Harari suggests a surprising reason for the rise of humanity.
ISIS, Hezbollah, Hamas. These three very different groups are known for violence — but that’s only a portion of what they do, says policy analyst Benedetti Berti. They also attempt to win over populations with social work: setting up schools and hospitals, offering safety and security, and filling the gaps left by weak governments. Understanding the broader work of these groups suggests new strategies for ending the violence.
As America becomes more and more multicultural, Rich Benjamin noticed a phenomenon: Some communities were actually getting less diverse. So he got out a map, found the whitest towns in the USA -- and moved in. In this funny, honest, human talk, he shares what he learned as a black man in Whitopia.
In the fog of war, civilian casualties often go uncounted. Artist Matt Kenyon, whose recent work memorialized the names and stories of US soldiers killed in the Iraq war, decided he should create a companion monument, to the Iraqi civilians caught in the war's crossfire. Learn how he built a secret monument to place these names in the official record.
Swallowing pills to get medication is a quick, painless and often not entirely effective way of treating disease. A potentially better way? Lasers. In this passionate talk, TED Fellow Patience Mthunzi explains her idea to use lasers to deliver drugs directly to cells infected with HIV. It's early days yet, but could a cure be on the horizon?
Alix Generous is a young woman with a million and one ideas -- she's done award-winning science, helped develop new technology and tells a darn good joke (you'll see). She has Asperger's, a form of autistic spectrum disorder that can impair the basic social skills required for communication, and she's worked hard for years to learn how to share her thoughts with the world. In this funny, personal talk, she shares her story -- and her vision for tools to help more people communicate their big ideas.
How does knowledge grow? Sometimes it begins with one insight and grows into many branches; other times it grows as a complex and interconnected network. Infographics expert Manuel Lima explores the thousand-year history of mapping data -- from languages to dynasties -- using trees and networks of information. It's a fascinating history of visualizations, and a look into humanity's urge to map what we know.
Tony Wyss-Coray studies the impact of aging on the human body and brain. In this eye-opening talk, he shares new research from his Stanford lab and other teams which shows that a solution for some of the less great aspects of old age might actually lie within us all.
Who is listening in on your phone calls? On a landline, it could be anyone, says privacy activist Christopher Soghoian, because surveillance backdoors are built into the phone system by default, to allow governments to listen in. But then again, so could a foreign intelligence service ... or a criminal. Which is why, says Soghoian, some tech companies are resisting governments' call to build the same backdoors into mobile phones and new messaging systems. From this TED Fellow, learn how some tech companies are working to keep your calls and messages private.
Dustin Yellin makes mesmerizing artwork that tells complex, myth-inspired stories. How did he develop his style? In this disarming talk, he shares the journey of an artist -- starting from age 8 -- and his idiosyncratic way of thinking and seeing. Follow the path that leads him up to his latest major work (or two).
How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called “spooky action at a distance” helps birds navigate, and quantum effects might explain the origin of life itself.
It seems like we wait for a disastrous disease outbreak before we get serious about making a vaccine for it. Seth Berkley lays out the market realities and unbalanced risks behind why we aren't making vaccines for the world's biggest diseases.
When disaster strikes, who's first on the scene? More and more, it’s a robot. In her lab, Robin Murphy builds robots that fly, tunnel, swim and crawl through disaster scenes, helping firefighters and rescue workers save more lives safely -- and help communities return to normal up to three years faster.
Modern work -- from waiting tables to crunching numbers to designing products -- is about solving brand-new problems every day, flexibly and collaboratively. But as Yves Morieux shows in this insightful talk, too often, an overload of rules, processes and metrics keeps us from doing our best work together. Meet the new frontier of productivity: cooperation.
When and how did the universe begin? A global group of astronomers wants to answer that question by peering as far back in time as a large new telescope will let us see. Wendy Freedman headed the creation of the Giant Magellan Telescope, under construction in South America; at TEDGlobal in Rio, she shares a bold vision of the discoveries about our universe that the GMT could make possible.
Around the world, women still struggle for equality in basic matters like access to education, equal pay and the right to vote. But how to enlist everyone, men and women, as allies for change? Meet Elizabeth Nyamayaro, head of UN Women’s HeForShe initiative, which has created more than 2.4 billion social media conversations about a more equal world. She invites us all to join in as allies in our shared humanity.
There’s a parallel Internet you may not have run across yet -- accessed by a special browser and home to a freewheeling collection of sites for everything from anonymous activism to illicit activities. Jamie Bartlett reports from the dark net.
Jim Simons was a mathematician and cryptographer who realized: the complex math he used to break codes could help explain patterns in the world of finance. Billions later, he’s working to support the next generation of math teachers and scholars. TED’s Chris Anderson sits down with Simons to talk about his extraordinary life in numbers.
On October 24, 2014, Alan Eustace donned a custom-built, 235-pound spacesuit, attached himself to a weather balloon, and rose above 135,000 feet, from which point he dove to Earth, breaking both the sound barrier and previous records for high-altitude jumps. Hear his story of how -- and why.
What makes work satisfying? Apart from a paycheck, there are intangible values that, Barry Schwartz suggests, our current way of thinking about work simply ignores. It's time to stop thinking of workers as cogs on a wheel.
At the end of our lives, what do we most wish for? For many, it’s simply comfort, respect, love. BJ Miller is a palliative care physician at Zen Hospice Project who thinks deeply about how to create a dignified, graceful end of life for his patients. Take the time to savor this moving talk, which asks big questions about how we think on death and honor life.
Tennis legend Billie Jean King isn't just a pioneer of women's tennis -- she's a pioneer for women getting paid. In this freewheeling conversation, she talks about identity, the role of sports in social justice and the famous Battle of the Sexes match against Bobby Riggs.
Does it seem like Washington has no new ideas? Instead of looking to build the future, it sometimes feels like the US political establishment happily retreats into fear and willful ignorance. Journalist David Rothkopf lays out a few of the major issues that US leadership is failing to address -- from cybercrime to world-shaking new tech to the reality of modern total war -- and calls for a new vision that sets fear aside.
As a global community, we all want to end poverty. Mia Birdsong suggests a great place to start: Let's honor the skills, drive and initiative that poor people bring to the struggle every day. She asks us to look again at people in poverty: They may be broke — but they're not broken.
Yes, we all know it’s the right thing to do. But Michael Kimmel makes the surprising, funny, practical case for treating men and women equally in the workplace and at home. It’s not a zero-sum game, but a win-win that will result in more opportunity and more happiness for everybody.
Did you know you can fall in love with anyone just by asking them 36 questions? Mandy Len Catron tried this experiment, it worked, and she wrote a viral article about it (that your mom probably sent you). But … is that real love? Did it last? And what’s the difference between falling in love and staying in love?
Scott Dinsmore quit a job that made him miserable, and spent the next four years wondering how to find work that was joyful and meaningful. He shares what he learned in this deceptively simple talk about finding out what matters to you — and then getting started doing it.
When the Taliban closed all the girls' schools in Afghanistan, Sakena Yacoobi set up new schools, in secret, educating thousands of women and men. In this fierce, funny talk, she tells the jaw-dropping story of two times when she was threatened to stop teaching -- and shares her vision for rebuilding her beloved country.
In a disturbing — but fascinating — walk through history, Frances Larson examines humanity's strange relationship with public executions … and specifically beheadings. As she shows us, they have always drawn a crowd, first in the public square and now on YouTube. What makes them horrific and compelling in equal measure?
Climate change is unfair. While rich countries can fight against rising oceans and dying farm fields, poor people around the world are already having their lives upended — and their human rights threatened — by killer storms, starvation and the loss of their own lands. Mary Robinson asks us to join the movement for worldwide climate justice.
When poet Robin Morgan found herself facing Parkinson’s disease, she distilled her experiences into these four quietly powerful poems — meditating on age, loss, and the simple power of noticing.
More than 40 million people worldwide suffer from Alzheimer’s disease, and that number is expected to increase drastically in the coming years. But no real progress has been made in the fight against the disease since its classification more than 100 years ago. Scientist Samuel Cohen shares a new breakthrough in Alzheimer’s research from his lab as well as a message of hope. “Alzheimer’s is a disease,” Cohen says, “and we can cure it.”

For centuries, people have viewed swamps and wetlands as obstacles to avoid. But for photographer Mac Stone, who documents the stories of wildlife in Florida's Everglades, the swamp isn't a hindrance — it's a national treasure. Through his stunning photographs, Stone shines a new light on a neglected, ancient and important wilderness. His message: get out and experience it for yourself. "Just do it — put your feet in the water," he says. "The swamp will change you, I promise."
Imagine being unable to say, "I am hungry," "I am in pain," "thank you," or "I love you,” — losing your ability to communicate, being trapped inside your body, surrounded by people yet utterly alone. For 13 long years, that was Martin Pistorius’s reality. After contracting a brain infection at the age of twelve, Pistorius lost his ability to control his movements and to speak, and eventually he failed every test for mental awareness. He had become a ghost. But then a strange thing started to happen — his mind began to knit itself back together. In this moving talk, Pistorius tells how he freed himself from a life locked inside his own body.
What do you want to be when you grow up? Well, if you're not sure you want to do just one thing for the rest of your life, you're not alone. In this illuminating talk, writer and artist Emilie Wapnick describes the kind of people she calls "multipotentialites" — who have a range of interests and jobs over one lifetime. Are you one?
Imagine the hottest day you've ever experienced. Now imagine it's six, 10 or 12 degrees hotter. According to climate researcher Alice Bows-Larkin, that's the type of future in store for us if we don't significantly cut our greenhouse gas emissions now. She suggests that it's time we do things differently—a whole system change, in fact—and seriously consider trading economic growth for climate stability.
Current medical treatment boils down to six words: Have disease, take pill, kill something. But physician Siddhartha Mukherjee points to a future of medicine that will transform the way we heal.
Designer and architect Neri Oxman is leading the search for ways in which digital fabrication technologies can interact with the biological world. Working at the intersection of computational design, additive manufacturing, materials engineering and synthetic biology, her lab is pioneering a new age of symbiosis between microorganisms, our bodies, our products and even our buildings.
Can we, as adults, grow new neurons? Neuroscientist Sandrine Thuret says that we can, and she offers research and practical advice on how we can help our brains better perform neurogenesis—improving mood, increasing memory formation and preventing the decline associated with aging along the way.
For musician Teitur, singing is about giving away a piece of yourself to others. "If your intentions are to impress people or to get the big applause at the end," he says, "then you are taking, not giving." Listen as he plays on stage at TED2015, offering two songs about love, distance and home.
Can we end hunger and poverty, halt climate change and achieve gender equality in the next 15 years? The governments of the world think we can. Meeting at the UN in September 2015, they agreed to a new set of Global Goals for the development of the world to 2030. Social progress expert Michael Green invites us to imagine how these goals and their vision for a better world can be achieved.
At his lab at the University of Pennsylvania, Vijay Kumar and his team have created autonomous aerial robots inspired by honeybees. Their latest breakthrough: Precision Farming, in which swarms of robots map, reconstruct and analyze every plant and piece of fruit in an orchard, providing vital information to farmers that can help improve yields and make water management smarter.
For most of the past century, drugs approved and released to market have been tested only on male patients, leading to improper dosing and unacceptable side effects for women. The important physiological differences between men and women have only recently been taken into consideration in medical research. Emergency doctor Alyson McGregor studies these differences, and in this fascinating talk she discusses the history behind how the male model became our framework for medical research and how understanding differences between men and women can lead to more effective treatments for both sexes.
When two bodies wearing identical wetsuits washed ashore in Norway and the Netherlands, reporter Anders Fjellberg and photographer Tomm Christiansen started a search to answer the question: who were these people? What they found and reported in Norway’s “Dagbladet” is that everybody has a name, everybody has a story and everybody is someone.
Using examples from birdsong, the natural lilt of emphatic language and even a cooking pan lid, singer-songwriter and TED Fellow Meklit Hadero shows how the everyday soundscape, even silence, makes music. "The world is alive with musical expression," she says. "We are already immersed."
Investigative journalist Will Potter is the only reporter who has been inside a Communications Management Unit, or CMU, within a US prison. These units were opened secretly, and radically alter how prisoners are treated -- even preventing them from hugging their children. Potter, a TED Fellow, shows us who is imprisoned here, and how the government is trying to keep them hidden. "The message was clear," he says. "Don’t talk about this place." Find sources for this talk at willpotter.com/cmu
Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called "designer babies." Doudna reviews how CRISPR-Cas9 works -- and asks the scientific community to pause and discuss the ethics of this new tool.
Designer Tom Uglow is creating a future in which humanity's love for natural solutions and simple tools can coexist with our need for information and the devices that provide us with it. "Reality is richer than screens," he says. "We can have a happy place filled with the information we love that feels as natural as switching on lightbulb."
Cave explorer and geologist Francesco Sauro travels to the hidden continent under our feet, surveying deep, dark places inside the earth that humans have never been able to reach before. In the spectacular tepuis of South America, he finds new minerals and insects that have evolved in isolation, and he uses his knowledge of these alien worlds to train astronauts.
When a family falls into crisis -- and it sometimes happens, thanks to unemployment, drugs, bad relationships and bad luck -- the social services system is supposed to step in and help them get back on track. As Hilary Cottam shows, in the UK a typical family in crisis can be eligible for services from more than 70 different agencies, but it's unlikely that any one of them can really make a difference. Cottam, a social entrepreneur herself, asks us to think about the ways we solve deep and complex social problems. How can we build supportive, enthusiastic relationships between those in need and those that provide help?
At the Harbour School in Hong Kong, TED Senior Fellow Cesar Harada teaches citizen science and invention to the next generation of environmentalists. He's moved his classroom into an industrial mega-space where imaginative kids work with wood, metal, chemistry, biology, optics and, occasionally, power tools to create solutions to the threats facing the world's oceans. There, he instills a universal lesson that his own parents taught him at a young age: "You can make a mess, but you have to clean up after yourself."
Artist and TED Fellow Christine Sun Kim was born deaf, and she was taught to believe that sound wasn't a part of her life, that it was a hearing person's thing. Through her art, she discovered similarities between American Sign Language and music, and she realized that sound doesn't have to be known solely through the ears -- it can be felt, seen and experienced as an idea. In this endearing talk, she invites us to open our eyes and ears and participate in the rich treasure of visual language.
In 2013, the world learned that the NSA and its UK equivalent, GCHQ, routinely spied on the German government. Amid the outrage, artists Mathias Jud and Christoph Wachter thought: Well, if they're listening ... let's talk to them. With antennas mounted on the roof of the Swiss Embassy in Berlin's government district, they set up an open network that let the world send messages to US and UK spies listening nearby. It's one of three bold, often funny, and frankly subversive works detailed in this talk, which highlights the world's growing discontent with surveillance and closed networks.
You're not at your best when you're stressed. In fact, your brain has evolved over millennia to release cortisol in stressful situations, inhibiting rational, logical thinking but potentially helping you survive, say, being attacked by a lion. Neuroscientist Daniel Levitin thinks there's a way to avoid making critical mistakes in stressful situations, when your thinking becomes clouded -- the pre-mortem. "We all are going to fail now and then," he says. "The idea is to think ahead to what those failures might be."
When a young woman texted DoSomething.org with a heartbreaking cry for help, the organization responded by opening a nationwide Crisis Text Line to provide an outlet for people in pain. Nearly 10 million text messages later, the organization is using the privacy and power of text messaging to help people with issues such as addiction, suicidal thoughts, eating disorders, sexual abuse and more. The data collected in the process is reshaping policy and preparing schools and law enforcement to better handle spikes in crises.
Aboard an overloaded ship carrying more than 500 refugees, a young woman becomes an unlikely hero. This single, powerful story, told by Melissa Fleming of the UN's refugee agency, gives a human face to the sheer numbers of human beings trying to escape to better lives ... as the refugee ships keep coming ...
Although the tapir is one of the world's largest land mammals, the lives of these solitary, nocturnal creatures have remained a mystery. Known as "the living fossil," the very same tapir that roams the forests and grasslands of South America today arrived on the evolutionary scene more than 5 million years ago. But threats from poachers, deforestation and pollution, especially in quickly industrializing Brazil, threaten this longevity. In this insightful talk, conservation biologist, tapir expert and TED Fellow Patrícia Medici shares her work with these amazing animals and challenges us with a question: Do we want to be responsible for their extinction?
What if we could use existing technologies to provide Internet access to the more than 4 billion people living in places where the infrastructure can't support it? Using off-the-shelf LEDs and solar cells, Harald Haas and his team have pioneered a new technology that transmits data using light, and it may just be the key to bridging the digital divide. Take a look at what the future of the Internet could look like.
A genre unto herself, Kaki King fuses the ancient tradition of working with one's hands with digital technology, projection-mapping imagery onto her guitar in her groundbreaking multimedia work "The Neck Is a Bridge to the Body." Using her guitar's neck like a keyboard, she plays an intricate melody as she takes the audience on a musical journey of light and sound. She calls it "guitar as paintbrush."
As a gay couple in San Francisco, Jenni Chang and Lisa Dazols had a relatively easy time living the way they wanted. But outside the bubble of the Bay Area, what was life like for people still lacking basic rights? They set off on a world tour in search of "Supergays," LGBT people who were doing something extraordinary in the world. In 15 countries across Africa, Asia and South America -- from India, recently home to the world's first openly gay prince, to Argentina, the first country in Latin America to grant marriage equality -- they found the inspiring stories and the courageous, resilient and proud Supergays they had been looking for.
Search engines have become our most trusted sources of information and arbiters of truth. But can we ever get an unbiased search result? Swedish author and journalist Andreas Ekström argues that such a thing is a philosophical impossibility. In this thoughtful talk, he calls on us to strengthen the bonds between technology and the humanities, and he reminds us that behind every algorithm is a set of personal beliefs that no code can ever completely eradicate.
How do we respect someone's religious beliefs, while also holding religion accountable for the damage those beliefs may cause? Chelsea Shields has a bold answer to this question. She was raised in the orthodox Mormon tradition, and she spent the early part of her life watching women be excluded from positions of importance within the LDS Church. Now, this anthropologist, activist and TED Fellow is working to reform her church's institutionalized gender inequality. "Religions can liberate or subjugate, they can empower or exploit, they can comfort or destroy," she says. "What is taught on the Sabbath leaks into our politics, our health policy, violence around the world."
In April 2003, just as American troops began rolling into Baghdad, a shell smashed into the building author and war correspondent Jean-Paul Mari was reporting from. There he had a face-to-face encounter with death, beginning his acquaintance with a phantom that has haunted those who have risked their lives on battlefields since ancient times. "What is this thing that can kill you without leaving any visible scars?" Mari asks. We know it as post-traumatic stress disorder -- or, as Mari describes it, an experience with the void of death. In this probing talk, he searches for answers to questions about mortality and psychosis and in the aftermath of horror and trauma.
Josh Luber is a "sneakerhead," a collector of rare or limited sneakers. With their insatiable appetite for exclusive sneakers, these tastemakers drive marketing and create hype for the brands they love, specifically Nike, which absolutely dominates the multi-billion dollar secondary market for sneakers. Luber's company, Campless, collects data about this market and analyzes it for collectors and investors. In this talk, he takes us on a journey into this complicated, unregulated market and imagines how it could be a model for a stock market for commerce.
What if you could experience a story with your entire body, not just with your mind? Nonny de la Peña is working on a new form of journalism that combines traditional reporting with emerging virtual reality technology to put the audience inside the story. The result is an evocative experience that de la Peña hopes will help people understand the news in a brand new way.
For the people of Kiribati, climate change isn't something to be debated, denied or legislated against -- it's an everyday reality. The low-lying Pacific island nation may soon be underwater, thanks to rising sea levels. In a personal conversation with TED Curator Chris Anderson, Kiribati President Anote Tong discusses his country's present climate catastrophe and its imperiled future. "In order to deal with climate change, there's got to be sacrifice. There's got to be commitment," he says. "We've got to tell people that the world has changed."
What's going on inside the brains of animals? Can we know what, or if, they're thinking and feeling? Carl Safina thinks we can. Using discoveries and anecdotes that span ecology, biology and behavioral science, he weaves together stories of whales, wolves, elephants and albatrosses to argue that just as we think, feel, use tools and express emotions, so too do the other creatures – and minds – that share the Earth with us.
Written language, the hallmark of human civilization, didn't just suddenly appear one day. Thousands of years before the first fully developed writing systems, our ancestors scrawled geometric signs across the walls of the caves they sheltered in. Paleoanthropologist, rock art researcher and TED Senior Fellow Genevieve von Petzinger has studied and codified these ancient markings in caves across Europe. The uniformity of her findings suggest that graphic communication, and the ability to preserve and transmit messages beyond a single moment in time, may be much older than we think.
Ann Morgan considered herself well read -- until she discovered the "massive blindspot" on her bookshelf. Amid a multitude of English and American authors, there were very few books from beyond the English-speaking world. So she set an ambitious goal: to read one book from every country in the world over the course of a year. Now she's urging other Anglophiles to read translated works so that publishers will work harder to bring foreign literary gems back to their shores. Explore interactive maps of her reading journey here: go.ted.com/readtheworld
Given the choice between a job candidate with a perfect resume and one who has fought through difficulty, human resources executive Regina Hartley always gives the "Scrapper" a chance. As someone who grew up with adversity, Hartley knows that those who flourish in the darkest of spaces are empowered with the grit to persist in an ever-changing workplace. "Choose the underestimated contender, whose secret weapons are passion and purpose," she says. "Hire the Scrapper."
Marina Abramović's art pushes the boundary between audience and artist in pursuit of heightened consciousness and personal change. In her groundbreaking 2010 work, "The Artist Is Present," she simply sat in a chair facing her audience, for eight hours a day ... with powerfully moving results. Her boldest work may still be yet to come -- it's taking the form of a sprawling art institute devoted to experimentation and simple acts done with mindful attention. "Nothing happens if you always do things the same way," she says. "My method is to do things I'm afraid of, the things I don't know, to go to territory that nobody's ever been."
Kristen Marhaver studies corals, tiny creatures the size of a poppyseed that, over hundreds of slow years, create beautiful, life-sustaining ocean structures hundreds of miles long. As she admits, it's easy to get sad about the state of coral reefs; they're in the news lately because of how quickly they're bleaching, dying and turning to slime. But the good news is that we're learning more and more about these amazing marine invertebrates -- including how to help them (and help them help us). This biologist and TED Senior Fellow offers a glimpse into the wonderful and mysterious lives of these hard-working and fragile creatures.
We need women to work, and we need working women to have babies. So why is America one of the only countries in the world that offers no national paid leave to new working mothers? In this incisive talk, Jessica Shortall makes the impassioned case that the reality of new working motherhood in America is both hidden and horrible: millions of women, every year, are forced back to work within just weeks of giving birth. Her idea worth spreading: the time has come for us to recognize the economic, physical and psychological costs of our approach to working mothers and their babies, and to secure our economic future by providing paid leave to all working parents.
How can technology help improve our quality of life? How can we navigate the world without using the sense of vision? Inventor and IBM Fellow Chieko Asakawa, who's been blind since the age of fourteen, is working on answering these questions. In a charming demo, she shows off some new technology that's helping blind people explore the world ever more independently ... because, she suggests, when we design for greater accessibility, everyone benefits.
In this breathtaking talk, world champion freediver Guillaume Néry takes us with him into the ocean's depths. Meter by meter, he explains the physical and emotional impact of water pressure, silence and holding your breath. His eloquent description of the underwater experience reveals the hidden poetry of freediving.
Jedidah Isler dreamt of becoming an astrophysicist since she was a young girl, but the odds were against her: At that time, only 18 black women in the United States had ever earned a PhD in a physics-related discipline. In this personal talk, she shares the story of how she became the first black woman to earn a PhD in astrophysics from Yale -- and her deep belief in the value of diversity to science and other STEM fields. "Do not think for one minute that because you are who you are, you cannot be who you imagine yourself to be," she says. "Hold fast to those dreams and let them carry you into a world you can't even imagine."
Downloadable, printable clothing may be coming to a closet near you. What started as designer Danit Peleg's fashion school project turned into a collection of 3D-printed designs that have the strength and flexibility for everyday wear. "Fashion is a very physical thing," she says. "I wonder what our world will look like when our clothes will be digital."
Raymond Wang is only 17 years old, but he's already helping to build a healthier future. Using fluid dynamics, he created computational simulations of how air moves on airplanes, and what he found is disturbing -- when a person sneezes on a plane, the airflow actually helps to spread pathogens to other passengers. Wang shares an unforgettable animation of how a sneeze travels inside a plane cabin as well as his prize-winning solution: a small, fin-shaped device that increases fresh airflow in airplanes and redirects pathogen-laden air out of circulation.
Nicole Paris was raised to be a beatboxer -- when she was young, her father, Ed Cage, used to beatbox her to sleep at night. Now the duo is known for their beatbox battles and jam sessions, which mix classic rap beats with electronic dance sounds. Prepare yourself for a bit of a hip-hop history lesson, and enjoy the show.
The way we fish for popular seafood such as salmon, tuna and shrimp is threatening to ruin our oceans. Paul Greenberg explores the sheer size and irrationality of the seafood economy, and suggests a few specific ways we can change it, to benefit both the natural world and the people who depend on fishing for their livelihoods.
Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA's Kepler mission, searching for places in the universe that could support life. So it's worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we'll eventually move to when we've messed up Earth, and to start thinking of planetary exploration and preservation of the Earth as two sides of the same goal. As she says, "The more you look for planets like Earth, the more you appreciate our own planet."
"If you want to go out and start your own cemetery" in the UK, says Alison Killing, "you kind of can." She thinks a lot about where we die and are buried -- and in this talk, the architect and TED Fellow offers an eye-opening economic and social perspective on an overlooked feature of our towns and cities: the cemetery. Speaking specifically to UK laws, she unpacks the fascinating, sometimes funny, often contradictory laws about where you can be buried.
Legendary duo Jane Fonda and Lily Tomlin have been friends for decades. In a raw, tender and wide-ranging conversation hosted by Pat Mitchell, the three discuss longevity, feminism, the differences between male and female friendship, what it means to live well and women's role in future of our planet. "I don't even know what I would do without my women friends," Fonda says. "I exist because I have my women friends."
UN High Commissioner for Refugees António Guterres thinks that we can solve the global refugee crisis -- and he offers compelling, surprising reasons why we must try. In conversation with TED's Bruno Giussani, Guterres discusses the historical causes of the current crisis and outlines the mood of the European countries that are trying to screen, shelter and resettle hundreds of thousands of desperate families. Bigger picture: Guterres calls for a multilateral turn toward acceptance and respect -- to defy groups like ISIS's anti-refugee propaganda and recruiting machine.
The Internet has transformed the front lines of war, and it's leaving governments behind. As security analyst Rodrigo Bijou shows, modern conflict is being waged online between non-state groups, activists and private corporations, and the digital landscape is proving to be fertile ground for the recruitment and radicalization of terrorists. Meanwhile, draconian surveillance programs are ripe for exploitation. Bijou urges governments to end mass surveillance programs and shut "backdoors" -- and he makes a bold call for individuals to step up.
For sculptor Jason deCaires Taylor, the ocean is more than a muse -- it's an exhibition space and museum. Taylor creates sculptures of human forms and mundane life on land and sinks them to the ocean floor, where they are subsumed by the sea and transformed from lifeless stone into vibrant habitats for corals, crustaceans and other creatures. The result: Enigmatic, haunting and colorful commentaries about our transient existence, the sacredness of the ocean and its breathtaking power of regeneration.
What keeps us happy and healthy as we go through life? If you think it's fame and money, you're not alone – but, according to psychiatrist Robert Waldinger, you're mistaken. As the director of a 75-year-old study on adult development, Waldinger has unprecedented access to data on true happiness and satisfaction. In this talk, he shares three important lessons learned from the study as well as some practical, old-as-the-hills wisdom on how to build a fulfilling, long life.
Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.
Does collecting more data lead to better decision-making? Competitive, data-savvy companies like Amazon, Google and Netflix have learned that data analysis alone doesn't always produce optimum results. In this talk, data scientist Sebastian Wernicke breaks down what goes wrong when we make decisions based purely on data -- and suggests a brainier way to use it.
Astronomer Aomawa Shields searches for clues that life might exist elsewhere in the universe by examining the atmospheres of distant exoplanets. When she isn't exploring the heavens, the classically trained actor (and TED Fellow) looks for ways to engage young women in the sciences using theater, writing and visual art. 'Maybe one day they'll join the ranks of astronomers who are full of contradictions,' she says, 'and use their backgrounds to discover, once and for all, that we are truly not alone in the universe.'
As the world's climate patterns continue to shift unpredictably, places where drinking water was once abundant may soon find reservoirs dry and groundwater aquifers depleted. In this talk, civil and environmental engineer David Sedlak shares four practical solutions to the ongoing urban water crisis. His goal: to shift our water supply towards new, local sources of water and create a system that is capable of withstanding any of the challenges climate change may throw at us in the coming years.
Suspicious emails: unclaimed insurance bonds, diamond-encrusted safe deposit boxes, close friends marooned in a foreign country. They pop up in our inboxes, and standard procedure is to delete on sight. But what happens when you reply? Follow along as writer and comedian James Veitch narrates a hilarious, weeks-long exchange with a spammer who offered to cut him in on a hot deal.
Challenges and problems can derail your creative process ... or they can make you more creative than ever. In the surprising story behind the best-selling solo piano album of all time, Tim Harford may just convince you of the advantages of having to work with a little mess.
We've invested so much in police departments as protectors that we have forgotten what it means to serve our communities, says Baltimore Police officer Lt. Colonel Melvin Russell. It's led to coldness and callousness, and it's dehumanized the police force. After taking over as district commander in one of Baltimore's toughest neighborhoods, Russell instituted a series of reforms aimed at winning back the trust of the community and lowering the violent crime rate. 'Law enforcement is in a crisis,' he says. 'But it's not too late for all of us to build our cities and nation to make it great again.'
Wael Ghonim helped touch off the Arab Spring in his home of Egypt ... by setting up a simple Facebook page. As he reveals, once the revolution spilled onto the streets, it turned from hopeful to messy, then ugly and heartbreaking. And social media followed suit. What was once a place for crowdsourcing, engaging and sharing became a polarized battleground. Ghonim asks: What can we do about online behavior now? How can we use the Internet and social media to create civility and reasoned argument?
For architect Ole Scheeren, the people who live and work inside a building are as much a part of that building as concrete, steel and glass. He asks: Can architecture be about collaboration and storytelling instead of the isolation and hierarchy of a typical skyscraper? Visit five of Scheeren's buildings -- from a twisted tower in China to a floating cinema in the ocean in Thailand -- and learn the stories behind them.
Cave diver Jill Heinerth explores the hidden underground waterways coursing through our planet. Working with biologists, climatologists and archaeologists, Heinerth unravels the mysteries of the life-forms that inhabit some of the earth's most remote places and helps researchers unlock the history of climate change. In this short talk, take a dive below the waves and explore the wonders of inner space.
As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: "resurrection plants" -- super-resilient plants that seemingly come back from the dead. Could they hold promise for growing food in our coming hotter, drier world?
If you read a poem and feel moved by it, but then find out it was actually written by a computer, would you feel differently about the experience? Would you think that the computer had expressed itself and been creative, or would you feel like you had fallen for a cheap trick? In this talk, writer Oscar Schwartz examines why we react so strongly to the idea of a computer writing poetry -- and how this reaction helps us understand what it means to be human.
The water hyacinth may look like a harmless, even beautiful flowering plant -- but it's actually an invasive aquatic weed that clogs waterways, stopping trade, interrupting schooling and disrupting everyday life. In this scourge, green entrepreneur Achenyo Idachaba saw opportunity. Follow her journey as she turns weeds into woven wonders.
The Sistine Chapel is one of the most iconic buildings on earth -- but there's a lot you probably don't know about it. In this tour-de-force talk, art historian Elizabeth Lev guides us across the famous building's ceiling and Michelangelo's vital depiction of traditional stories, showing how the painter reached beyond the religious iconography of the time to chart new artistic waters. Five hundred years after the artist painted it, says Lev, the Sistine Chapel forces us to look around as if it were a mirror and ask, "Who am I, and what role do I play in this great theater of life?"
Have you wondered why politicians aren't what they used to be, why governments seem unable to solve real problems? Economist Yanis Varoufakis, the former Minister of Finance for Greece, says that it's because you can be in politics today but not be in power -- because real power now belongs to those who control the economy. He believes that the mega-rich and corporations are cannibalizing the political sphere, causing financial crisis. In this talk, hear his dream for a world in which capital and labor no longer struggle against each other, "one that is simultaneously libertarian, Marxist and Keynesian."
Just a few meters below the waves, marine biologist and explorer-photographer David Gruber discovered something amazing -- a surprising new range of sea creatures that glow in many colors in the ocean's dim blue light. Join his journey in search of biofluorescent sharks, seahorses, sea turtles and more, and learn how these light-up creatures could illuminate a new understanding of our own brains.
A decade ago, US law said human genes were patentable -- which meant patent holders had the right to stop anyone from sequencing, testing or even looking at a patented gene. Troubled by the way this law both harmed patients and created a barrier to biomedical innovation, Tania Simoncelli and her colleagues at the ACLU challenged it. In this riveting talk, hear the story of how they took a case everybody told them they would lose all the way to the Supreme Court.
Roboticist Auke Ijspeert designs biorobots, machines modeled after real animals that are capable of handling complex terrain and would appear at home in the pages of a sci-fi novel. The process of creating these robots leads to better automata that can be used for fieldwork, service, and search and rescue. But these robots don't just mimic the natural world -- they help us understand our own biology better, unlocking previously unknown secrets of the spinal cord.
Plastic bags are essentially indestructible, yet they're used and thrown away with reckless abandon. Most end up in the ocean, where they pollute the water and harm marine life; the rest are burned in garbage piles, where they release harmful dioxins into the atmosphere. Melati and Isabel Wijsen are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. Their efforts -- including petitions, beach cleanups, even a hunger strike -- paid off when they convinced their governor to commit to a plastic bag-free Bali by 2018. "Don't ever let anyone tell you that you're too young or you won't understand," Isabel says to other aspiring activists. "We're not telling you it's going to be easy. We're telling you it's going to be worth it."
Computer code is the next universal language, and its syntax will be limited only by the imaginations of the next generation of programmers. Linda Liukas is helping to educate problem-solving kids, encouraging them to see computers not as mechanical, boring and complicated but as colorful, expressive machines meant to be tinkered with. In this talk, she invites us to imagine a world where the Ada Lovelaces of tomorrow grow up to be optimistic and brave about technology and use it to create a new world that is wonderful, whimsical and a tiny bit weird.
When Andrés Ruzo was a young boy in Peru, his grandfather told him a story with an odd detail: There is a river, deep in the Amazon, which boils as if a fire burns below it. Twelve years later, after training as a geoscientist, he set out on a journey deep into the jungle of South America in search of this boiling river. At a time when everything seems mapped and measured, join Ruzo as he explores a river that forces us to question the line between known and unknown ... and reminds us that there are great wonders yet to be discovered.
Can we break bad habits by being more curious about them? Psychiatrist Judson Brewer studies the relationship between mindfulness and addiction -- from smoking to overeating to all those other things we do even though we know they're bad for us. Learn more about the mechanism of habit development and discover a simple but profound tactic that might help you beat your next urge to smoke, snack or check a text while driving.
When Ebola broke out in March 2014, Pardis Sabeti and her team got to work sequencing the virus's genome, learning how it mutated and spread. Sabeti immediately released her research online, so virus trackers and scientists from around the world could join in the urgent fight. In this talk, she shows how open cooperation was key to halting the virus ... and to attacking the next one to come along. 'We had to work openly, we had to share and we had to work together,' Sabeti says. 'Let us not let the world be defined by the destruction wrought by one virus, but illuminated by billions of hearts and minds working in unity.'
How much do you know about intellectual disabilities? Special Olympics champion and ambassador Matthew Williams is proof that athletic competition and the camaraderie it fosters can transform lives, both on and off the field. Together with his fellow athletes, he invites you to join him at the next meet -- and challenges you to walk away with your heart unchanged.
Economic growth is the defining challenge of our time; without it, political and social instability rises, human progress stagnates and societies grow dimmer. But, says economist Dambisa Moyo, dogmatic capitalism isn't creating the growth we need. As she shows, in both state-sponsored and market-driven models, capitalism is failing to solve social ills, fostering corruption and creating income inequality. Moyo surveys the current economic landscape and suggests that we have to start thinking about capitalism as a spectrum so we can blend the best of different models together to foster growth.
What will the world look like when we move beyond the keyboard and mouse? Interaction designer Sean Follmer is building a future with machines that bring information to life under your fingers as you work with it. In this talk, check out prototypes for a 3D shape-shifting table, a phone that turns into a wristband, a deformable game controller and more that may change the way we live and work.
Gregory Heyworth is a textual scientist; he and his lab work on new ways to read ancient manuscripts and maps using spectral imaging technology. In this fascinating talk, watch as Heyworth shines a light on lost history, deciphering texts that haven't been read in thousands of years. How could these lost classics rewrite what we know about the past?
We're headed towards a global food crisis: Nearly 3 billion people depend on the ocean for food, and at our current rate we already take more fish from the ocean than it can naturally replace. In this fact-packed, eye-opening talk, entrepreneur and conservationist Mike Velings proposes a solution: Aquaculture, or fish farming. "We must start using the ocean as farmers instead of hunters," he says, echoing Jacques Cousteau. "The day will come where people will demand farmed fish on their plates that's farmed well and farmed healthy -- and refuse anything less."
Social justice advocate and law scholar Dorothy Roberts has a precise and powerful message: Race-based medicine is bad medicine. Even today, many doctors still use race as a medical shortcut; they make important decisions about things like pain tolerance based on a patient's skin color instead of medical observation and measurement. In this searing talk, Roberts lays out the lingering traces of race-based medicine -- and invites us to be a part of ending it. "It is more urgent than ever to finally abandon this backward legacy," she says, "and to affirm our common humanity by ending the social inequalities that truly divide us."
Through treating everything from strokes to car accident traumas, neurosurgeon Jocelyne Bloch knows the brain's inability to repair itself all too well. But now, she suggests, she and her colleagues may have found the key to neural repair: Doublecortin-positive cells. Similar to stem cells, they are extremely adaptable and, when extracted from a brain, cultured and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. 'With a little help,' Bloch says, 'the brain may be able to help itself.'
When your job hinges on how well you talk to people, you learn a lot about how to have conversations -- and that most of us don't converse very well. Celeste Headlee has worked as a radio host for decades, and she knows the ingredients of a great conversation: Honesty, brevity, clarity and a healthy amount of listening. In this insightful talk, she shares 10 useful rules for having better conversations. "Go out, talk to people, listen to people," she says. "And, most importantly, be prepared to be amazed."
Shonda Rhimes, the titan behind Grey's Anatomy, Scandal and How to Get Away With Murder, is responsible for some 70 hours of television per season, and she loves to work. "When I am hard at work, when I am deep in it, there is no other feeling," she says. She has a name for this feeling: The hum. The hum is a drug, the hum is music, the hum is God's whisper in her ear. But what happens when it stops? Is she anything besides the hum? In this moving talk, join Rhimes on a journey through her "year of yes" and find out how she got her hum back.
More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. 'All that energy was pumped into the fabric of time and space itself,' says theoretical physicist Allan Adams, 'making the universe explode in roiling waves of gravity.' About 25 years ago, a group of scientists built a giant laser detector called LIGO to search for these kinds of waves, which had been predicted but never observed. In this mind-bending talk, Adams breaks down what happened when, in September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.
When you hear the word "drone," you probably think of something either very useful or very scary. But could they have aesthetic value? Autonomous systems expert Raffaello D'Andrea develops flying machines, and his latest projects are pushing the boundaries of autonomous flight -- from a flying wing that can hover and recover from disturbance to an eight-propeller craft that's ambivalent to orientation ... to a swarm of tiny coordinated micro-quadcopters. Prepare to be dazzled by a dreamy, swirling array of flying machines as they dance like fireflies above the TED stage.
Al Gore has three questions about climate change and our future. First: Do we have to change? Each day, global-warming pollution traps as much heat energy as would be released by 400,000 Hiroshima-class atomic bombs. This trapped heat is leading to stronger storms and more extreme floods, he says: "Every night on the TV news now is like a nature hike through the Book of Revelation." Second question: Can we change? We've already started. So then, the big question: Will we change? In this challenging, inspiring talk, Gore says yes. "When any great moral challenge is ultimately resolved into a binary choice between what is right and what is wrong, the outcome is foreordained because of who we are as human beings," he says. "That is why we're going to win this."
When you look at Muslim scholar Dalia Mogahed, what do you see: a woman of faith? a scholar, a mom, a sister? or an oppressed, brainwashed, potential terrorist? In this personal, powerful talk, Mogahed asks us, in this polarizing time, to fight negative perceptions of her faith in the media -- and to choose empathy over prejudice.
Can global capital markets become catalysts for social change? According to investment expert Audrey Choi, individuals own almost half of all global capital, giving them (us!) the power to make a difference by investing in companies that champion social values and sustainability. "We have more opportunity today than ever before to make choices," she says. "So change your perspective. Invest in the change you want to see in the world."
In Zimbabwe in the 1980s, Mary Bassett witnessed the AIDS epidemic firsthand, and she helped set up a clinic to treat and educate local people about the deadly virus. But looking back, she regrets not sounding the alarm for the real problem: the structural inequities embedded in the world's political and economic organizations, inequities that make marginalized people more vulnerable. These same structural problems exist in the United States today, and as New York City's Health Commissioner, Bassett is using every chance she has to rally support for health equity and speak out against racism. 'We don't have to have all the answers to call for change,' she says. 'We just need courage.'
There are a few things that we all need: fresh air, water, food, shelter, love ... and a safe place to pee. For trans people who don't fit neatly into the gender binary, public restrooms are a major source of anxiety and the place where they are most likely to be questioned or harassed. In this poetically rhythmic talk, Ivan Coyote grapples with complex and intensely personal issues of gender identity and highlights the need for gender-neutral bathrooms in all public places.

Textile artist Magda Sayeg transforms urban landscapes into her own playground by decorating everyday objects with colorful knit and crochet works. These warm, fuzzy 'yarn bombs' started small, with stop sign poles and fire hydrants in Sayeg's hometown, but soon people found a connection to the craft and spread it across the world. 'We all live in this fast-paced, digital world, but we still crave and desire something that's relatable,' Sayeg says. 'Hidden power can be found in the most unassuming places, and we all possess skills that are just waiting to be discovered.'
If you take two different medications for two different reasons, here's a sobering thought: your doctor may not fully understand what happens when they're combined, because drug interactions are incredibly hard to study. In this fascinating and accessible talk, Russ Altman shows how doctors are studying unexpected drug interactions using a surprising resource: search engine queries.
A million refugees arrived in Europe this year, says Alexander Betts, and "our response, frankly, has been pathetic." Betts studies forced migration, the impossible choice for families between the camps, urban poverty and dangerous illegal journeys to safety. In this insightful talk, he offers four ways to change the way we treat refugees, so they can make an immediate contribution to their new homes. "There's nothing inevitable about refugees being a cost," Betts says. "They're human beings with skills, talents, aspirations, with the ability to make contributions -- if we let them."
Uber didn't start out with grand ambitions to cut congestion and pollution. But as the company took off, co-founder Travis Kalanick wondered if there was a way to get people using Uber along the same routes to share rides, reducing costs and carbon footprint along the way. The result: uberPOOL, the company's carpooling service, which in its first eight months took 7.9 million miles off the roads and 1,400 metric tons of carbon dioxide out of the air in Los Angeles. Now, Kalanick says carpooling could work for commuters in the suburbs, too. 'With the technology in our pockets today, and a little smart regulation,' he says, 'we can turn every car into a shared car, and we can reclaim our cities starting today.'
We're raising our girls to be perfect, and we're raising our boys to be brave, says Reshma Saujani, the founder of Girls Who Code.

It doesn't matter whether you love or hate guns; it's obvious that the US would be a safer place if there weren't thousands of them sold every day without background checks. Dan Gross, president of the Brady Campaign to Prevent Gun Violence, makes a passionate, personal appeal for something that more than 90 percent of Americans want: background checks for all gun sales. 'For every great movement around the world, there's a moment where you can look back and say, 'That's when things really started to change,'' Gross says. 'For the movement to end gun violence in America, that moment is here.'
If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on Earth - such as the ability to withstand radiation - to make humans more fit for exploring space. 'We're approaching a time during which we'll have the capacity to decide our own genetic destiny,' Nip says. 'Augmenting the human body with new abilities is no longer a question of how, but of when.'

For four billion years, what lived and died on Earth depended on two principles: natural selection and random mutation. Then humans came along and changed everything — hybridizing plants, breeding animals, altering the environment and even purposefully evolving ourselves. Juan Enriquez provides five guidelines for a future where this ability to program life rapidly accelerates. 'This is the single most exciting adventure human beings have been on,' Enriquez says. 'This is the single greatest superpower humans have ever had.'
It's true: talking about menstruation makes many people uncomfortable. And that taboo has consequences: in India, three out of every 10 girls don't even know what menstruation is at the time of their first period, and restrictive customs related to periods inflict psychological damage on young girls. Growing up with this taboo herself, Aditi Gupta knew she wanted to help girls, parents and teachers talk about periods comfortably and without shame. She shares how she did it.
What happens when you discover a dinosaur Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus - a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet - and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.
Trust: How do you earn it?

Hear how TED Fellow Shivani Siroya is unlocking untapped purchasing power in the developing world with InVenture, a start-up that uses mobile data to create a financial identity. "With something as simple as a credit score," says Siroya, "we're giving people the power to build their own futures."
Artist R. Luke DuBois makes unique portraits of presidents, cities, himself and even Britney Spears using data and personality. In this talk, he shares nine projects - from maps of the country built using information taken from millions of dating profiles to a gun that fires a blank every time a shooting is reported in New Orleans. His point: the way we use technology reflects on us and our culture, and we reduce others to data points at our own peril.
When Ameera Harouda hears the sounds of bombs or shells, she heads straight towards them.

What are your dreams Better yet, what are your broken dreams Dan Pallotta dreams of a time when we are as excited, curious and scientific about the development of our humanity as we are about the development of our technology. 'What we fear most is that we will be denied the opportunity to fulfill our true potential,' Pallotta says. 'Imagine living in a world where we simply recognize that deep, existential fear in one another - and love one another boldly because we know that to be human is to live with that fear.'
Science fiction writer Monica Byrne imagines rich worlds populated with characters who defy our racial, social and gender stereotypes.

Lee explains why we should celebrate when kids start to lie and presents new lie-detection technology that could someday reveal our hidden emotions.
What if we could peek inside our brains and see our dreams - or even shape them Studying memory-specific brain cells, neuroscientist (and ex-hacker) Moran Cerf found that our sleeping brains retain some of the content we encounter when we're awake and that our dreams can influence our waking actions. Where could this lead us 'Neuroscientists are now giving us a new tool to control our dreams,' Cerf says, 'a new canvas that flickers to life when we fall asleep.'
Anyone who has lost a loved one to pancreatic cancer knows the devastating speed with which it can affect an otherwise healthy person. TED Fellow and biomedical entrepreneur Laura Indolfi is developing a revolutionary way to treat this complex and lethal disease: a drug delivery device that acts as a cage at the site of a tumor, preventing it from spreading and delivering medicine only where it's needed. 'We are hoping that one day we can make pancreatic cancer a curable disease,' she says.
Sebastian Junger has seen war up close, and he knows the impact that battlefield trauma has on soldiers. But he suggests there's another major cause of pain for veterans when they come home: the experience of leaving the tribal closeness of the military and returning to an alienating and bitterly divided modern society. 'Sometimes, we ask ourselves if we can save the vets,' Junger says. 'I think the real question is if we can save ourselves.' (This talk comes from the PBS special 'TED Talks: War & Peace,' which premieres Monday, May 30 at 9 p.m. EST.)
Everyone has an opinion about how to legislate sex work (whether to legalize it, ban it or even tax it) ... but what do workers themselves think would work best Activist Toni Mac explains four legal models that are being used around the world and shows us the model that she believes will work best to keep sex workers safe and offer greater self-determination. 'If you care about gender equality or poverty or migration or public health, then sex worker rights matter to you,' she says. 'Make space for us in your movements.' (Adult themes)
In the US, the press has a right to publish secret information the public needs to know, protected by the First Amendment. Government surveillance has made it increasingly more dangerous for whistleblowers, the source of virtually every important story about national security since 9/11, to share information. In this concise, informative talk, Freedom of the Press Foundation co-founder and TED Fellow Trevor Timm traces the recent history of government action against individuals who expose crime and injustice and advocates for technology that can help them do it safely and anonymously.
To those who feel like they don't belong: there is beauty in being a misfit. Author Lidia Yuknavitch shares her own wayward journey in an intimate recollection of patchwork stories about loss, shame and the slow process of self-acceptance.

'I hope they can serve as records of sublime landscapes in flux.'
The barbershop can be a safe haven for black men, a place for honest conversation and trust - and, as physician Joseph Ravenell suggests, a good place to bring up tough topics about health. He's turning the barbershop into a place to talk about medical problems that statistically affect black men more often and more seriously, like high blood pressure. It's a new approach to problem solving with broad applications. 'What is your barbershop' he asks. 'Where is that place for you where people affected by a unique problem can meet a unique solution'
Before he fought in the galactic battles of Star Wars: The Force Awakens, Adam Driver was a United States Marine with 1/1 Weapons Company. He tells the story of how and why he became a Marine, the complex transition from soldier to civilian - and Arts in the Armed Forces, his nonprofit that brings theater to the military.

It's already helped cut HIV transmission from mothers to babies by nearly half in sub-Saharan Africa, and now it's being used to address alarming infant mortality rates all over the world. The goal: to save lives by bringing the right interventions to the right populations at the right time.
In some parts of the world, it's easier to get an automatic rifle than a glass of clean drinking water. Is this just the way it is Samantha Nutt, doctor and founder of the international humanitarian organization War Child, explores the global arms trade - and suggests a bold, common sense solution for ending the cycle of violence. 'War is ours,' she says. 'We buy it, sell it, spread it and wage it. We are therefore not powerless to solve it.'
In the 1970s (and decades following), TV producer Norman Lear touched the lives of millions with culture-altering sitcoms like All in the Family, The Jeffersons and Good Times, pushing the boundaries of the era and giving a primetime voice to underrepresented Americans. In an intimate, smart conversation with Eric Hirshberg, he shares with humility and humor how his early relationship with 'the foolishness of the human condition' shaped his life and creative vision.

'Once upon a time in America,' says professor Sajay Samuel, 'going to college did not mean graduating with debt.' Today, higher education has become a consumer product - costs have skyrocketed, saddling students with a combined debt of over $1 trillion, while universities and loan companies make massive profits. Samuel proposes a radical solution: link tuition costs to a degree's expected earnings, so that students can make informed decisions about their future, restore their love of learning and contribute to the world in a meaningful way.
TED Fellow Negin Farsad weaves comedy and social commentary to cleverly undercut stereotypes of her culture. In this uproarious talk/stand-up hybrid, Farsad speaks on her documentary, The Muslims Are Coming!, narrates her fight with the MTA in New York and offers a detailed breakdown of the different types of haters she's encountered in her work. 'Comedy is one of our best weapons,' she says. 'We've tried a lot of approaches to social justice, like war and competitive ice dancing - but a lot of things are still kind of awful. I think it's time we try and tell a really good poop joke.'
Half of the world's poorest people have something in common: they're small farmers.

We're not going to end violence by telling people that it's morally wrong, says Jamila Raqib, executive director of the Albert Einstein Institution. Instead, we must find alternative ways to conduct conflict that are equally powerful and effective. Raqib promotes nonviolent resistance to people living under tyranny - and there's a lot more to it than street protests. She shares encouraging examples of creative strategies that have led to change around the world and a message of hope for a future without armed conflict. 'The greatest hope for humanity lies not in condemning violence but in making violence obsolete,' Raqib says.
TED Fellow Andrew Pelling is a biohacker, and nature is his hardware. His favorite materials are the simplest ones (and oftentimes he finds them in the garbage).

Ninety-six percent of genome studies are based on people of European descent. The rest of the world is virtually unrepresented - and this is dangerous, says geneticist and TED Fellow Keolu Fox, because we react to drugs differently based on our genetic makeup. Fox is working to democratize genome sequencing, specifically by advocating for indigenous populations to get involved in research, with the goal of eliminating health disparities. 'The research community needs to immerse itself in indigenous culture,' he says, 'or die trying.'

What caused the war in Syria? Oppression, drought and religious differences all played key roles, but Marwa Al-Sabouni suggests another reason: architecture. Speaking to us over the Internet from Homs, where for the last six years she has watched the war tear her city apart, Al-Sabouni suggests that Syria's architecture divided its once tolerant and multicultural society into single-identity enclaves defined by class and religion. The country's future now depends on how it chooses to rebuild.
We are embarrassingly unaware of how divided our societies are, and Brexit grew out of a deep, unexamined divide between those that fear globalization and those that embrace it, says social scientist Alexander Betts.

Summer, 2016: amid populist revolts, clashing resentments and fear, writer Anand Giridharadas doesn't give a talk but reads a letter. It's from those who have won in this era of change, to those who have, or feel, lost. It confesses to ignoring pain until it became anger. It chides an idealistic yet remote elite for its behind-closed-doors world-saving and airy, self-serving futurism — for at times worrying more about sending people to Mars than helping them on Earth. And it rejects the exclusionary dogmas to which we cling, calling us instead to "dare to commit to the dream of each other."

For the first time in history, the majority of American parents don't think their kids will be better off than they were. This shouldn't be a cause for alarm, says journalist Courtney Martin. Rather, it's an opportunity to define a new approach to work and family that emphasizes community and creativity. "The biggest danger is not failing to achieve the American Dream," she says in a talk that will resonate far beyond the US. "The biggest danger is achieving a dream that you don't actually believe in."

"Unapologetic fat bodies can blow people's minds," she says.
The smartphone you use reflects more than just personal taste ... it could determine how closely you can be tracked, too. Privacy expert and TED Fellow Christopher Soghoian details a glaring difference between the encryption used on Apple and Android devices and urges us to pay attention to a growing digital security divide. "If the only people who can protect themselves from the gaze of the government are the rich and powerful, that's a problem," he says. "It's not just a cybersecurity problem -- it's a civil rights problem."
Why should a good education be exclusive to rich kids? Schools in low-income neighborhoods across the US, specifically in communities of color, lack resources that are standard at wealthier schools -- things like musical instruments, new books, healthy school lunches and soccer fields -- and this has a real impact on the potential of students. Kandice Sumner sees the disparity every day in her classroom in Boston. In this inspiring talk, she asks us to face facts -- and change them.
Your company might have donated money to help solve humanitarian issues, but you could have something even more useful to offer: your data.

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.

In this important talk about mental health, she speaks openly about her struggle -- and why communities of color must undo the stigma that misreads depression as a weakness and keeps sufferers from getting help.
Sara Menker quit a career in commodities trading to figure out how the global value chain of agriculture works. Her discoveries have led to some startling predictions: "We could have a tipping point in global food and agriculture if surging demand surpasses the agricultural system's structural capacity to produce food," she says. "People could starve and governments may fall." Menker's models predict that this scenario could happen in a decade -- that the world could be short 214 trillion calories per year by 2027. She offers a vision of this impossible world as well as some steps we can take today to avoid it.

What do you think would happen if you invited an individual with mental health issues who had been homeless for many years to move directly from the street into housing? Loyd Pendleton shares how he went from skeptic to believer in the Housing First approach to homelessness -- providing the displaced with short-term assistance to find permanent housing quickly and without conditions -- and how it led to a 91 percent reduction in chronic homelessness over a ten-year period in Utah.
Military leaders have known for millennia that the time to prepare for a challenge is before it hits you, says scientist and retired US Navy officer David Titley. He takes us from the humanitarian catastrophe in Syria to the icy shores of Svalbard to show how the military approaches the threat of climate change, in a refreshingly practical, nonpartisan take on climate preparedness. "The ice doesn't care who's in the White House. It doesn't care which party controls your congress. It doesn't care which party controls your parliament," Titley says. "It just melts."

Niti Bhan studies business strategy for Africa's informal markets: the small shops and stands, skilled craftspeople and laborers who are the invisible engine that keeps the continent's economy running. It's tempting to think of these workers as tax-dodgers, even criminals -- but Bhan makes the case that this booming segment of the economy is legitimate and worthy of investment. "These are the fertile seeds of businesses and enterprises," Bhan says. "Can we start by recognizing these skills and occupations?"
The combined market capitalization of Amazon, Apple, Facebook and Google is now equivalent to the GDP of India. How did these four companies come to infiltrate our lives so completely?

Followed by a Q&A with TED Curator Chris Anderson. (Note: This talk contains graphic language.)
For the introverts among us, traditional forms activism like marches, protests and door-to-door canvassing can be intimidating and stressful. Take it from Sarah Corbett, a former professional campaigner and self-proclaimed introvert. She introduces us to "craftivism," a quieter form of activism that uses handicrafts as a way to get people to slow down and think deeply about the issues they're facing, all while engaging the public more gently. Who says an embroidered handkerchief can't change the world?

Join the TED Fellow as she shares her work trying to better understand how the Sun affects us here on Earth.
Africa needs engineers, but its engineering students often end up working at auditing firms and banks. Why? Kamau Gachigi suspects it's because they don't have the spaces and materials needed to test their ideas and start businesses. To solve this problem, Gachigi started Gearbox, a makerspace and hardware accelerator that provides a rapid prototyping environment for both professionals and people with no formal engineering background. In this forward-thinking talk, he shares some of the extraordinary projects and innovations coming out of his Kenyan fab lab.
Since the widespread use of antibiotics began in the 1940s, we've tried to develop new drugs faster than bacteria can evolve -- but this strategy isn't working. Drug-resistant bacteria known as superbugs killed nearly 700,000 people last year, and by 2050 that number could be 10 million -- more than cancer kills each year. Can physics help? In a talk from the frontiers of science, radiation scientist David Brenner shares his work studying a potentially life-saving weapon: a wavelength of ultraviolet light known as far-UVC, which can kill superbugs safely, without penetrating our skin. Followed by a Q&A with TED Curator Chris Anderson.

Learn more about these mysterious microbes, which refuse to grow in the lab and seem to have a fundamentally different relationship with time and energy than we do.
Su Kahumbu raises badass cows — healthy, well-fed animals whose protein is key to solving a growing crisis in Africa: childhood nutritional stunting. With iCow, a simple SMS service she developed to support small-scale livestock farmers, the TED Fellow is helping farmers across the continent by texting them tips on caring for and raising animals. Learn more about how this cheap innovation is helping feed hungry kids, one text at a time.
If architect and writer John Cary has his way, women will never need to stand in pointlessly long bathroom lines again. Lines like these are representative of a more serious issue, Cary says: the lack of diversity in design that leads to thoughtless, compassionless spaces. Design has a unique ability to dignify and make people feel valued, respected, honored and seen — but the flip side is also true. Cary calls for architects and designers to expand their ranks and commit to serving the public good, not just the privileged few. "Well-designed spaces are not just a matter of taste or a questions of aesthetics," he says. "They literally shape our ideas about who we are in the world and what we deserve." And we all deserve better.
Mohamad Jebara loves mathematics — but he's concerned that too many students grow up thinking that this beautiful, rewarding subject is difficult and boring. His company is experimenting with a bold idea: paying students for completing weekly math homework. He explores the ethics of this model and how it's helping students — and why learning math is crucial in the era of fake news.
The democratic process is messy, complicated and often inefficient — but across Africa, activists are redefining democracy by putting protest at its center. In an illuminating talk, political scientist Zachariah Mampilly gives us a primer on the current wave of protests reshaping countries like Tunisia, Malawi and Zimbabwe — and explains how this form of political dissension expands our political imaginations beyond what we're told is possible.

Bhu Srinivasan researches the intersection of capitalism and technological progress. Instead of thinking about capitalism as a firm, unchanging ideology, he suggests that we should think of it as an operating system — one that needs upgrades to keep up with innovation, like the impending take-off of drone delivery services. Learn more about the past and future of the free market (and a potential coming identity crisis for the United States' version of capitalism) with this quick, forward-thinking talk.
What is it about unfairness? Whether it's not being invited to a friend's wedding or getting penalized for bad luck or an honest mistake, unfairness often makes us so upset that we can't think straight. And it's not just a personal issue — it's also bad for business, says Marco Alverà. He explains how his company works to create a culture of fairness — and how tapping into our innate sense of what's right and wrong makes for happier employees and better results.
The hymen is still the most misunderstood part of the female body. Nina Dølvik Brochmann and Ellen Støkken Dahl share their mission to empower young people through better sex education, debunking the popular (and harmful) myths we're told about female virginity and the hymen.
Dixon Chibanda is one of 12 psychiatrists in Zimbabwe — for a population of more than 16 million. Realizing that his country would never be able to scale traditional methods of treating those with mental health issues, Chibanda helped to develop a beautiful solution powered by a limitless resource: grandmothers. In this extraordinary, inspirational talk, learn more about the friendship bench program, which trains grandmothers in evidence-based talk therapy and brings care, and hope, to those in need.
"To be African is to be inspired by culture and to be filled with undying hope for the future," says designer and TED Fellow Walé Oyéjidé. With his label Ikiré Jones (you'll see their work in Marvel's "Black Panther"), he uses classic design to showcase the elegance and grace of often-marginalized groups, in beautifully cut clothing that tells a story.
What happens to the clothes we don't buy? You might think that last season's coats, trousers and turtlenecks end up being put to use, but most of it (nearly 13 million tons each year in the United States alone) ends up in landfills. Fashion has a waste problem, and Amit Kalra wants to fix it. He shares some creative ways the industry can evolve to be more conscientious about the environment — and gain a competitive advantage at the same time.
We often find ourselves stuck in narrow social circles with similar people. What habits confine us, and how can we break them? Organizational psychologist Tanya Menon considers how we can be more intentional about expanding our social universes — and how it can lead to new ideas and opportunities.
As a research scientist at Google, Margaret Mitchell helps develop computers that can communicate about what they see and understand. She tells a cautionary tale about the gaps, blind spots and biases we subconsciously encode into AI — and asks us to consider what the technology we create today will mean for tomorrow. "All that we see now is a snapshot in the evolution of artificial intelligence," Mitchell says. "If we want AI to evolve in a way that helps humans, then we need to define the goals and strategies that enable that path now."
Very few of us hold jobs that line up directly with our past experiences or what we studied in college. Take TED Resident Jason Shen; he studied biology but later became a product manager at a tech company. In this quick, insightful talk about human potential, Shen shares some new thinking on how job seekers can make themselves more attractive — and why employers should look for ability over credentials.
Every three years, more than 30 million Hindu worshippers gather for the Kumbh Mela in India, the world's largest religious gathering, in order to wash away their sins. With massive crowds descending on small cities and towns, stampedes inevitably happen, and in 2003, 39 people were killed during the festival. In 2014, then 15-year-old Nilay Kulkarni decided to put his skills as a self-taught programmer to use by building a tech solution to help prevent stampedes. Learn more about his invention — and how it helped the 2015 Nashik Kumbh Mela have zero stampedes and casualties.
From our fear of women's bodies to our sheepishness around the word "nipple," our ideas about sex need an upgrade, say sex educators (and hilarious women) Tiffany Kagure Mugo and Siphumeze Khundayi. For a radical new take on sex positivity, the duo take the TED stage to suggest we look to Africa for erotic wisdom both ancient and modern, showing us how we can shake off problematic ideas about sex we've internalized and re-define pleasure on our own terms. (This talk contains mature content.)
The prevailing image of where refugees live is of temporary camps in isolated areas — but in reality, nearly 60 percent of them worldwide end up in urban areas. TED Fellow Robert Hakiza takes us inside the lives of urban refugees — and shows us how organizations like the one that he started can provide them with the skills they need to ultimately become self-sufficient.
Driving in Johannesburg one day, Tapiwa Chiwewe noticed an enormous cloud of air pollution hanging over the city. He was curious and concerned but not an environmental expert — so he did some research and discovered that nearly 14 percent of all deaths worldwide in 2012 were caused by household and ambient air pollution. With this knowledge and an urge to do something about it, Chiwewe and his colleagues developed a platform that uncovers trends in pollution and helps city planners make better decisions. "Sometimes just one fresh perspective, one new skill set, can make the conditions right for something remarkable to happen," Chiwewe says. "But you need to be bold enough to try."
If we hope to heal the racial tensions that threaten to tear the fabric of society apart, we're going to need the skills to openly express ourselves in racially stressful situations. Through racial literacy — the ability to read, recast and resolve these situations — psychologist Howard C. Stevenson helps children and parents reduce and manage stress and trauma. In this inspiring, quietly awesome talk, learn more about how this approach to decoding racial threat can help youth build confidence and stand up for themselves in productive ways.
Do human emotions have a role to play in science and research? Material researcher Ilona Stengel suggests that instead of opposing each other, emotions and logic complement and reinforce each other. She shares a case study on how properly using emotions (like the empowering feeling of being dedicated to something meaningful) can boost teamwork and personal development — and catalyze scientific breakthroughs and innovation.
How do we find fulfillment in a world that's constantly changing? Raymond Tang struggled with this question until he came across the ancient Chinese philosophy of the Tao Te Ching. In it, he found a passage comparing goodness to water, an idea he's now applying to his everyday life. In this charming talk, he shares three lessons he's learned so far from the "philosophy of water." "What would water do?" Tang asks. "This simple and powerful question ... has changed my life for the better."

A 2.4-mile swim, a 112-mile bicycle ride and then a full-length marathon on hot, dry ground — with no breaks in between: the legendary Ironman triathlon in Kona, Hawaii, is a bucket list goal for champion athletes. But when Minda Dentler decided to take it on, she had bigger aspirations than just another medal around her neck. She tells the story of how she conquered this epic race, and what it inspired her to do next.
"Soccer is the only thing on this planet that we can all agree to do together," says theater maker and TED Fellow Marc Bamuthi Joseph. Through his performances and an engagement initiative called "Moving and Passing," Joseph combines music, dance and soccer to reveal accessible, joyful connections between the arts and sports. Learn more about how he's using the beautiful game to foster community and highlight issues facing immigrants.
Experimental psychologist Petter Johansson researches choice blindness — a phenomenon where we convince ourselves that we're getting what we want, even when we're not. In an eye-opening talk, he shares experiments (designed in collaboration with magicians!) that aim to answer the question: Why do we do what we do? The findings have big implications for the nature of self-knowledge and how we react in the face of manipulation. You may not know yourself as well as you think you do.
No one thinks twice about a woman wearing blue jeans in New York City — but when Nobel laureate Malala wears them, it's a political act. Around the globe, individuality can be a crime, and clothing can be a form of protest. In a talk about the power of what we wear, Kaustav Dey examines how fashion gives us a nonverbal language of dissent and encourages us to embrace our authentic selves.
Things are pretty shocking out there right now — record-breaking storms, deadly terror attacks, thousands of migrants disappearing beneath the waves and openly supremacist movements rising. Are we responding with the urgency that these overlapping crises demand from us? Journalist and activist Naomi Klein studies how governments use large-scale shocks to push societies backward. She shares a few propositions from "The Leap" — a manifesto she wrote alongside indigenous elders, climate change activists, union leaders and others from different backgrounds — which envisions a world after we've already made the transition to a clean economy and a much fairer society. "The shocking events that fill us with dread today can transform us, and they can transform the world for the better," Klein says. "But first we need to picture the world that we're fighting for. And we have to dream it up together."
"Hold your breath," says inventor Tom Zimmerman. "This is the world without plankton." These tiny organisms produce two-thirds of our planet's oxygen — without them, life as we know it wouldn't exist. In this talk and tech demo, Zimmerman and cell engineer Simone Bianco hook up a 3D microscope to a drop of water and take you scuba diving with plankton. Learn more about these mesmerizing creatures and get inspired to protect them against ongoing threats from climate change.
As CEO of the Global Fund for Women, Musimbi Kanyoro works to support women and their ideas so they can expand and grow. She introduces us to the Maragoli concept of "isirika" — a pragmatic way of life that embraces the mutual responsibility to care for one another — something she sees women practicing all over the world. And she calls for those who have more to give more to people working to improve their communities. "Imagine what it would look like if you embraced isirika and made it your default," Kanyoro says. "What could we achieve for each other? For humanity?" Let's find out — together.
A 24-hour helpline in the UK known as Samaritans helped Sophie Andrews become a survivor of abuse rather than a victim. Now she's paying the favor back as the founder of The Silver Line, a helpline that supports lonely and isolated older people. In a powerful, personal talk, she shares why the simple act of listening (instead of giving advice) is often the best way to help someone in need.
Throughout his colorful career and bodies of work, Iké Udé has found creative ways to reject the negative portrayal of Africans rampant in Western media. In this tour of his work, he shares evocative portraits that blend clothing, props and poses from many cultures at once into sharp takes on the varied, complex beauty of Africa.
Deanna Van Buren designs restorative justice centers that, instead of taking the punitive approach used by a system focused on mass incarceration, treat crime as a breach of relationships and justice as a process where all stakeholders come together to repair that breach. With help and ideas from incarcerated men and women, Van Buren is creating dynamic spaces that provide safe venues for dialogue and reconciliation; employment and job training; and social services to help keep people from entering the justice system in the first place. "Imagine a world without prisons," Van Buren says. "And join me in creating all the things that we could build instead."
According to the US Department of Education, more than 85 percent of black fourth-grade boys aren't proficient in reading. What kind of reading experiences should we be creating to ensure that all children read well? In a talk that will make you rethink how we teach, educator and author Alvin Irby explains the reading challenges that many black children face — and tells us what culturally competent educators do to help all children identify as readers.
"Will machines replace humans?" This question is on the mind of anyone with a job to lose. Daniel Susskind confronts this question and three misconceptions we have about our automated future, suggesting we ask something else: How will we distribute wealth in a world when there will be less — or even no — work?

Sometimes, a single decision can change the course of history. Join journalist and author Isabel Wilkerson as she tells the story of the Great Migration, the outpouring of six million African Americans from the Jim Crow South to cities in the North and West between World War I and the 1970s. This was the first time in American history that the lowest caste people signaled they had options and were willing to take them — and the first time they had a chance to choose for themselves what they would do with their innate talents, Wilkerson explains. "These people, by their actions, were able to do what the powers that be, North and South, could not or would not do," she says. "They freed themselves."
The arts bring meaning to our lives and spirit to our culture — so why do we expect artists to struggle to make a living? Hadi Eldebek is working to create a society where artists are valued through an online platform that matches artists with grants and funding opportunities — so they can focus on their craft instead of their side hustle.
Singer-songwriter Rei brings her mix of indie rock and blues to the TED stage in a performance of two songs, "my mama" and "BLACK BANANA."
We're all against hate, right? We agree it's a problem — their problem, not our problem, that is. But as Sally Kohn discovered, we all hate — some of us in subtle ways, others in obvious ones. As she confronts a hard story from her own life, she shares ideas on how we can recognize, challenge and heal from hatred in our institutions and in ourselves.
Something strange and deadly is happening inside the brains of top athletes — a degenerative condition, possibly linked to concussions, that causes dementia, psychosis and far-too-early death. It's called chronic traumatic encephalopathy, or CTE, and it's the medical mystery that Chris Nowinski wants to solve by analyzing brains after death. It's also why, when Nowinski meets a pro athlete, his first question is: "Can I have your brain?" Hear more from this ground-breaking effort to protect athletes' brains — and yours, too.
Director and playwright Adong Judith creates provocative art that sparks dialogue on issues from LGBTQ rights to war crimes. In this quick but powerful talk, the TED Fellow details her work — including the play "Silent Voices," which brought victims of the Northern Ugandan war against Joseph Kony's rebel group together with political, religious and cultural leaders for transformative talks. "Listening to one another will not magically solve all problems," Judith says. "But it will give a chance to create avenues to start to work together to solve many of humanity's problems."
Liz Ogbu is an architect who works on spatial justice: the idea that justice has a geography and that the equitable distribution of resources and services is a human right. In San Francisco, she's questioning the all too familiar story of gentrification: that poor people will be pushed out by development and progress. "Why is it that we treat culture erasure and economic displacement as inevitable?" she asks, calling on developers, architects and policymakers to instead "make a commitment to build people's capacity to stay in their homes, to stay in their communities, to stay where they feel whole."
We use rituals to mark the early stages of our lives, like birthdays and graduations — but what about our later years? In this meditative talk about looking both backward and forward, Bob Stein proposes a new tradition of giving away your things (and sharing the stories behind them) as you get older, to reflect on your life so far and open the door to whatever comes next.
In 2014, as a newly trained physician, Soka Moses took on one of the toughest jobs in the world: treating highly contagious patients at the height of Liberia's Ebola outbreak. In this intense, emotional talk, he details what he saw on the frontlines of the crisis — and reveals the challenges and stigma that thousands of survivors still face.
"Where do great ideas come from?" Starting with this question in mind, Vittorio Loreto takes us on a journey to explore a possible mathematical scheme that explains the birth of the new. Learn more about the "adjacent possible" — the crossroads of what's actual and what's possible — and how studying the math that drives it could explain how we create new ideas.
The United States locks up more people than any other country in the world, says documentarian Eve Abrams, and somewhere between one and four percent of those in prison are likely innocent. That's 87,000 brothers, sisters, mothers and fathers — predominantly African American — unnecessarily separated from their families, their lives and dreams put on hold. Using audio from her interviews with incarcerated people and their families, Abrams shares touching stories of those impacted by mass incarceration and calls on us all to take a stand and ensure that the justice system works for everyone.
From Beyoncé to Drake and beyond, the world is rocking to the rhythm of Afrobeat. Feel the music as Kenyan afro-pop superstars Sauti Sol take the TED stage to perform three songs: "Live and Die in Afrika," "Sura Yako" and "Kuliko Jana."
Amishi Jha studies how we pay attention: the process by which our brain decides what's important out of the constant stream of information it receives. Both external distractions (like stress) and internal ones (like mind-wandering) diminish our attention's power, Jha says — but some simple techniques can boost it. "Pay attention to your attention," Jha says.
What if we incentivized doctors to keep us healthy instead of paying them only when we're already sick? Matthias Müllenbeck explains how this radical shift from a sick care system to a true health care system could save us from unnecessary costs and risky procedures — and keep us healthier for longer.
As quantum computing matures, it's going to bring unimaginable increases in computational power along with it — and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.
Each year, the world loses enough food to feed half a billion people to fungi, the most destructive pathogens of plants. Mycologist and TED Fellow Mennat El Ghalid explains how a breakthrough in our understanding of the molecular signals fungi use to attack plants could disrupt this interaction — and save our crops.
In the US, your taxes fund academic research at public universities. Why then do you need to pay expensive, for-profit journals for the results of that research? Erica Stone advocates for a new, open-access relationship between the public and scholars, making the case that academics should publish in more accessible media. "A functioning democracy requires that the public be well-educated and well-informed," Stone says. "Instead of research happening behind paywalls and bureaucracy, wouldn't it be better if it was unfolding right in front of us?"
Ndidi Nwuneli has advice for Africans who believe in God — and Africans who don't. To the religious, she advises against using God to outsource responsibility for what happens in their lives. To the non-religious, she asks that they keep an open mind and work with faith-based organizations, especially on issues like health care and education. "There's so much potential that can be realized when we walk across the divide of faith and, hand in hand, try to solve many of our problems," Nwuneli says.
As a humanist, Leo Igwe doesn't believe in divine intervention — but he does believe in the power of human beings to alleviate suffering, cure disease, preserve the planet and turn situations of poverty into prosperity. In this bold talk, Igwe shares how humanism can free Africans from damaging superstitions and give them the power to rebuild the continent.
Four decades ago, Judith Heumann helped to lead a groundbreaking protest called the Section 504 sit-in — in which disabled-rights activists occupied a federal building for almost a month, demanding greater accessibility for all. In this personal, inspiring talk, Heumann tells the stories behind the protest — and reminds us that, 40 years on, there's still work left to do.
At 14, Christian Picciolini went from naïve teenager to white supremacist — and soon, the leader of the first neo-Nazi skinhead gang in the United States. How was he radicalized, and how did he ultimately get out of the movement? In this courageous talk, Picciolini shares the surprising and counterintuitive solution to hate in all forms.
How can we make AI that people actually want to interact with? Raphael Arar suggests we start by making art. He shares interactive projects that help AI explore complex ideas like nostalgia, intuition and conversation — all working towards the goal of making our future technology just as much human as it is artificial.
Irina Kareva translates biology into mathematics and vice versa. She writes mathematical models that describe the dynamics of cancer, with the goal of developing new drugs that target tumors. "The power and beauty of mathematical modeling lies in the fact that it makes you formalize, in a very rigorous way, what we think we know," Kareva says. "It can help guide us to where we should keep looking, and where there may be a dead end." It all comes down to asking the right question and translating it to the right equation, and back.
In 2009, journalist and screenwriter Drew Philp bought a ruined house in Detroit for $500. In the years that followed, as he gutted the interior and removed the heaps of garbage crowding the rooms, he didn't just learn how to repair a house — he learned how to build a community. In a tribute to the city he loves, Philp tells us about "radical neighborliness" and makes the case that we have "the power to create the world anew together and to do it ourselves when our governments refuse."
There's no such thing as throwing something away, says Andrew Dent — when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. Dent shares exciting examples of thrift — the idea of using and reusing what you need so you don't have to purchase anything new — as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.
In this perspective-shifting talk, Danny Hillis prompts us to approach global issues like climate change with creative scientific solutions. Taking a stand for solar geoengineering, he looks at controversial solutions with open-minded curiosity.
In this talk-performance hybrid, drummer, percussionist and TED Fellow Kasiva Mutua shares how she's breaking the taboo against female drummers in Kenya — and her mission to teach the significance and importance of the drum to young boys, women and girls. "Women can be custodians of culture, too," Mutua says.
Still invisible and often an afterthought, indigenous peoples are uniting to protect the world's water, lands and history — while trying to heal from genocide and ongoing inequality. Tribal attorney and Couchiching First Nation citizen Tara Houska chronicles the history of attempts by government and industry to eradicate the legitimacy of indigenous peoples' land and culture, including the months-long standoff at Standing Rock which rallied thousands around the world. "It's incredible what you can do when you stand together," Houska says. "Stand with us — empathize, learn, grow, change the conversation."
After Hurricane Maria hit Puerto Rico in 2017, chef José Andrés traveled to the devastated island with a simple idea: to feed the hungry. Millions of meals served later, Andrés shares the remarkable story of creating the world's biggest restaurant — and the awesome power of letting people in need know that somebody cares about them.
There are about 7,000 languages spoken around the world — and they all have different sounds, vocabularies and structures. But do they shape the way we think? Cognitive scientist Lera Boroditsky shares examples of language — from an Aboriginal community in Australia that uses cardinal directions instead of left and right to the multiple words for blue in Russian — that suggest the answer is a resounding yes. "The beauty of linguistic diversity is that it reveals to us just how ingenious and how flexible the human mind is," Boroditsky says. "Human minds have invented not one cognitive universe, but 7,000."
Malika Whitley is the founder of ChopArt, an organization for homeless teens focused on mentorship, dignity and opportunity through the arts. In this moving, personal talk, she shares her story of homelessness and finding her voice through arts — and her mission to provide a creative outlet for others who have been pushed to the margins of society.
In the early days of digital culture, Jaron Lanier helped craft a vision for the internet as public commons where humanity could share its knowledge — but even then, this vision was haunted by the dark side of how it could turn out: with personal devices that control our lives, monitor our data and feed us stimuli. (Sound familiar?) In this visionary talk, Lanier reflects on a "globally tragic, astoundingly ridiculous mistake" companies like Google and Facebook made at the foundation of digital culture — and how we can undo it. "We cannot have a society in which, if two people wish to communicate, the only way that can happen is if it's financed by a third person who wishes to manipulate them," he says.
On any given night, more than 450,000 people in the United States are locked up in jail simply because they don't have enough money to pay bail. The sums in question are often around $500: easy for some to pay, impossible for others. This has real human consequences — people lose jobs, homes and lives, and it drives racial disparities in the legal system. Robin Steinberg has a bold idea to change this. In this powerful talk, she outlines the plan for The Bail Project — an unprecedented national revolving bail fund to fight mass incarceration. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)
What will we find in the twilight zone: the vast, mysterious, virtually unexplored realm hundreds of meters below the ocean's surface? Heidi M. Sosik of Woods Hole Oceanographic Institution wants to find out. In this wonder-filled talk, she shares her plan to investigate these uncharted waters, which may hold a million new species and 90 percent of the world's fish biomass, using submersible technology. What we discover there won't just astound us, Sosik says — it will help us be better stewards of the world's oceans. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)
Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today — but it's also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper's organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books — and how you can help. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)
When we talk about greenhouse gases, carbon dioxide gets the most attention — but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming. Environmentalist Fred Krupp has an idea to fix the problem: launch a satellite that tracks global methane emissions, and openly share the data it collects with the public. Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)
In the ongoing debate over refugees, we hear from everyone — from politicians who pledge border controls to citizens who fear they'll lose their jobs — everyone, that is, except migrants themselves. Why are they coming? Journalist and TED Fellow Yasin Kakande explains what compelled him and many others to flee their homelands, urging a more open discussion and a new perspective. Because humanity's story, he reminds us, is a story of migration: "There are no restrictions that could ever be so rigorous to stop the wave of migration that has determined our human history," he says.
Unlike the solar cells you're used to seeing, organic photovoltaics are made of compounds that are dissolved in ink and can be printed and molded using simple techniques. The result is a low-weight, flexible, semi-transparent film that turns the energy of the sun into electricity. Hannah Bürckstümmer shows us how they're made — and how they could change the way we power the world.
Why do we still think that drug use is a law-enforcement issue? Making drugs illegal does nothing to stop people from using them, says public health expert Mark Tyndall. So, what might work? Tyndall shares community-based research that shows how harm-reduction strategies, like safe-injection sites, are working to address the drug overdose crisis.
Ocean expert Nancy Rabalais tracks the ominously named "dead zone" in the Gulf of Mexico — where there isn't enough oxygen in the water to support life. The Gulf has the second largest dead zone in the world; on top of killing fish and crustaceans, it's also killing fisheries in these waters. Rabalais tells us about what's causing it — and how we can reverse its harmful effects and restore one of America's natural treasures.
We get stronger, not weaker, by engaging with ideas and people we disagree with, says Zachary R. Wood. In an important talk about finding common ground, Wood makes the case that we can build empathy and gain understanding by engaging tactfully and thoughtfully with controversial ideas and unfamiliar perspectives. "Tuning out opposing viewpoints doesn't make them go away," Wood says. "To achieve progress in the face of adversity, we need a genuine commitment to gaining a deeper understanding of humanity."
Diane Wolk-Rogers teaches history at Marjory Stoneman Douglas High School in Parkland, Florida, site of a horrific school shooting on Valentine's Day 2018. How can we end this senseless violence? In a stirring talk, Wolk-Rogers offers three ways Americans can move forward to create more safety and responsibility around guns — and invites people to come up with their own answers, too. Above all, she asks us to take a cue from the student activists at her school, survivors whose work for change has moved millions to action. "They shouldn't have to do this on their own," Wolk-Rogers says. "They're asking you to get involved."
What's up at SpaceX? Engineer Gwynne Shotwell was employee number seven at Elon Musk's pioneering aerospace company and is now its president. In conversation with TED curator Chris Anderson, she discusses SpaceX's race to put people into orbit and the organization's next big project, the BFR (ask her what it stands for). The new giant rocket is designed to take humanity to Mars — but it has another potential use: space travel for earthlings.
Clemantine Wamariya was six years old when the Rwandan Civil War forced her and her sister to flee their home in Kigali, leaving their parents and everything they knew behind. In this deeply personal talk, she tells the story of how she became a refugee, living in camps in seven countries over the next six years — and how she's tried to make sense of what came after.
By expanding boundaries, exploring possibilities and conveying truth, films have helped change Africa's reality (even before "Black Panther"). Dayo Ogunyemi invites us to imagine Africa's future through the lens of inspiring filmmakers from across the continent, showing us how they can inspire Africa to make a hundred-year leap.
The global collection of women's experiences can no longer be ignored, says actress and activist Tracee Ellis Ross. In a candid, fearless talk, she delivers invitations to a better future to both men and women.
When lawyer Sarah Donnelly was diagnosed with breast cancer, she turned to her friends and family for support — but she also found meaning, focus and stability in her work. In a personal talk about why and how she stayed on the job, she shares her insights on how workplaces can accommodate people going through major illnesses — because the benefits go both ways.
Qudus Onikeku and The QTribe summon a downpour with a poetic, powerful dance performance. Set to a composition of singing, drums and strings, the dancers radiate energy — moving in circles, in shapes and in unison as they consume the TED stage.
Digital creator Dylan Marron has racked up millions of views for projects like "Every Single Word" and "Sitting in Bathrooms With Trans People" — but he's found that the flip side of success online is internet hate. Over time, he's developed an unexpected coping mechanism: calling the people who leave him insensitive comments and asking a simple question: "Why did you write that?" In a thoughtful talk about how we interact online, Marron explains how sometimes the most subversive thing you can do is actually speak with people you disagree with, not simply at them.
Was 2017 really the "worst year ever," as some would have us believe? In his analysis of recent data on homicide, war, poverty, pollution and more, psychologist Steven Pinker finds that we're doing better now in every one of them when compared with 30 years ago. But progress isn't inevitable, and it doesn't mean everything gets better for everyone all the time, Pinker says. Instead, progress is problem-solving, and we should look at things like climate change and nuclear war as problems to be solved, not apocalypses in waiting. "We will never have a perfect world, and it would be dangerous to seek one," he says. "But there's no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing."
If you want to build a team of innovative problem-solvers, you should value the humanities just as much as the sciences, says entrepreneur Eric Berridge. He shares why tech companies should look beyond STEM graduates for new hires — and how people with backgrounds in the arts and humanities can bring creativity and insight to technical workplaces.
Andrologist John Amory is developing innovative male contraception that gives men a new option for taking responsibility to prevent unintended pregnancy. He details the science in development — and why the world needs a male pill.
To make accountability the norm after gender violence in the United States, we need to change tactics, says victims' rights attorney and TED Fellow Laura L. Dunn. Instead of going institution by institution, fighting for reform, we need to go to the Constitution and finally pass the Equal Rights Amendment, which would require states to address gender inequality and violence. By ushering in sweeping change, Dunn says, "our legal system can become a system of justice, and #MeToo can finally become 'no more.'"
What good is a sophisticated piece of medical equipment to people in Africa if it can't handle the climate there? Biomedical engineer Tania Douglas shares stories of how we're often blinded to real needs in our pursuit of technology — and how a deeper understanding of the context where it's used can lead us to better solutions.
Blending traditional Yoruba culture with sharp modern songwriting, electro-soul duo (and twin sisters) Ibeyi play a transportive set of two songs: "Valé" and "River."
Trust is the foundation for everything we do. But what do we do when it's broken? In an eye-opening talk, Harvard Business School professor Frances Frei gives a crash course in trust: how to build it, maintain it and rebuild it — something she worked on during a recent stint at Uber. "If we can learn to trust one another more, we can have unprecedented human progress," Frei says.
Over the last year, Priya Vulchi and Winona Guo traveled to all 50 US states, collecting personal stories about race and intersectionality. Now they're on a mission to equip every American with the tools to understand, navigate and improve a world structured by racial division. In a dynamic talk, Vulchi and Guo pair the personal stories they've collected with research and statistics to reveal two fundamental gaps in our racial literacy — and how we can overcome them.
Frustrated by her lack of self-determination in the housing market, Sarah Murray created a computer game that allows home buyers to design a house and have it delivered to them in modular components that can be assembled on-site. Learn how her effort is putting would-be homeowners in control of the largest purchase of their lives — as well as cutting costs, protecting the environment and helping provide homes for those in need.
In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions — designed to chop vegetables, cut hair, apply lipstick and more — rarely (if ever) succeed, and that's the point. "The true beauty of making useless things [is] this acknowledgment that you don't always know what the best answer is," Giertz says. "It turns off that voice in your head that tells you that you know exactly how the world works. Maybe a toothbrush helmet isn't the answer, but at least you're asking the question."
LB Hannahs candidly shares the experience of parenting as a genderqueer individual — and what it can teach us about authenticity and advocacy. "Authenticity doesn't mean 'comfortable.' It means managing and negotiating the discomfort of everyday life," Hannahs says.
Self-styled wild woman and rebel singer Thandiswa Mazwai rocks the TED stage with an electrifying performance of two songs: "Iyeza" and "Zabalaza."
Sex educator Emily Nagoski breaks down one of the most dangerous myths about sex and introduces us to the science behind arousal nonconcordance: when there's a disconnect between physical response and the experience of pleasure and desire. Talking about such intimate, private moments can feel awkward or difficult, yet in this straightforward talk Nagoski urges all of us to share this crucial information with someone — judges, lawyers, partners, kids. "With every brave conversation we have, we make the world that little bit better," says Nagoski. (This talk contains mature content.)
What would a sustainable, universally beneficial economy look like? "Like a doughnut," says Oxford economist Kate Raworth. In a stellar, eye-opening talk, she explains how we can move countries out of the hole — where people are falling short on life's essentials — and create regenerative, distributive economies that work within the planet's ecological limits.
Local humanitarians are beacons of light in the darkness of war, says humanitarian aid entrepreneur and TED Fellow Rola Hallam. She's working to help responders on the ground in devastated communities like Syria, where the destruction of health care is being used as a weapon of war. One of her campaigns achieved a global first: a crowdfunded hospital. Since it opened in 2017, the aptly named Hope Hospital has treated thousands of children. "Local humanitarians have the courage to persist, to dust themselves off from the wreckage and to start again, risking their lives to save others," Hallam says. "We can match their courage by not looking away or turning our backs."
"You do not mess with something so fundamental, so precious, as science," says Kirsty Duncan, Canada's first Minister of Science. In a heartfelt, inspiring talk about pushing boundaries, she makes the case that researchers must be free to present uncomfortable truths and challenge the thinking of the day — and that we all have a duty to speak up when we see science being stifled or suppressed.
From rides to homes and beyond, we're sharing everything these days, with the help of digital tools. But as modern and high-tech as the sharing economy seems, it's been alive in Africa for centuries, according to author Robert Neuwirth. He shares fascinating examples — like apprenticeships that work like locally generated venture capital and systems for allocating scarce water — and says that if we can propagate and scale these models, they could help communities thrive from the bottom up.
TED Fellow Nighat Dad studies online harassment, especially as it relates to patriarchal cultures like the one in her small village in Pakistan. She tells the story of how she set up Pakistan's first cyber harassment helpline, offering support to women who face serious threats online. "Safe access to the internet is access to knowledge, and knowledge is freedom," she says. "When I fight for a woman's digital rights, I am fighting for equality."
Cellist and singer Helen Gillet mixes her classical training, New Orleans-based jazz roots and free improvisational skills to perform her own eclectic music. In a powerful, melodious performance, she plays her song "You Found Me."
In a profound talk about technology and power, author and historian Yuval Noah Harari explains the important difference between fascism and nationalism — and what the consolidation of our data means for the future of democracy. Appearing as a hologram live from Tel Aviv, Harari warns that the greatest danger that now faces liberal democracy is that the revolution in information technology will make dictatorships more efficient and capable of control. "The enemies of liberal democracy hack our feelings of fear and hate and vanity, and then use these feelings to polarize and destroy," Harari says. "It is the responsibility of all of us to get to know our weaknesses and make sure they don't become weapons." (Followed by a brief conversation with TED curator Chris Anderson)
Cherry blossoms and rainbows, bubbles and googly eyes: Why do some things seem to create such universal joy? In this captivating talk, Ingrid Fetell Lee reveals the surprisingly tangible roots of joy and shows how we all can find — and create — more of it in the world around us.
Michael Rain is on a mission to tell the stories of first-generation immigrants, who have strong ties both to the countries they grew up in and their countries of origin. In a personal talk, he breaks down the mischaracterizations and limited narratives of immigrants and shares the stories of the worlds they belong to. "We're walking melting pots of culture," Rain says. "If something in that pot smells new or different to you, don't turn up your nose. Ask us to share."
Research investigator Michael Hendryx studies mountaintop removal, an explosive type of surface coal mining used in Appalachia that comes with unexpected health hazards.

With her signature wit and wisdom, Emily Levine meets her ultimate challenge as a comedian/philosopher: she makes dying funny. In this personal talk, she takes us on her journey to make friends with reality — and peace with death. Life is an enormous gift, Levine says: "You enrich it as best you can, and then you give it back."
Business school professor Amy Edmondson studies "teaming," where people come together quickly (and often temporarily) to solve new, urgent or unusual problems. Recalling stories of teamwork on the fly, such as the incredible rescue of 33 miners trapped half a mile underground in Chile in 2010, Edmondson shares the elements needed to turn a group of strangers into a quick-thinking team that can nimbly respond to challenges.
Is there someone in your life dealing with anxiety, depression or thoughts of suicide — but is too ashamed to talk about it? Jeremy Forbes saw this happening around him, and now he's on a mission to teach people how to start a conversation about it. In this deeply personal talk, Forbes shares his approach to helping a group of traditionally silent men in his community open up about their struggles. "We can all be life preservers," he says.
Comic books and graphic novels belong in every teacher's toolkit, says cartoonist and educator Gene Luen Yang. Set against the backdrop of his own witty, colorful drawings, Yang explores the history of comics in American education — and reveals some unexpected insights about their potential for helping kids learn.
Children who live in rural areas can have a hard time getting to the doctor — much less to an audiologist's clinic for expensive, complex tests to check their hearing. The result for too many kids is hearing loss caused by ear infections and other curable or preventable problems. That's why ear surgeon and TED Fellow Susan Emmett is working with 15 communities in rural Alaska to create a simple, low-cost test that only requires a cell phone. Learn more about her work and how it could change the lives of children who don't have access to hearing care.
Working out of her garage, Anushka Naiknaware designed a sensor that tracks wound healing, becoming the youngest winner (at age 13) of the Google Science Fair. Her clever invention addresses the global challenge of chronic wounds, which don't heal properly due to preexisting conditions like diabetes and account for billions in medical costs worldwide. Join Naiknaware as she explains how her "smart bandage" works — and how she's sharing her story to inspire others to make a difference.
Humans will soon have new bodies that forever blur the line between the natural and synthetic worlds, says bionics designer Hugh Herr. In an unforgettable talk, he details "NeuroEmbodied Design," a methodology for creating cyborg function that he's developing at the MIT Media Lab, and shows us a future where we've augmented our bodies in a way that will redefine human potential — and, maybe, turn us into superheroes. "During the twilight years of this century, I believe humans will be unrecognizable in morphology and dynamics from what we are today," Herr says. "Humanity will take flight and soar."
Gardens are mirrors of our lives, says environmental artist tobacco brown, and we must cultivate them with care to harvest their full beauty. Drawing on her experience bringing natural public art installations to cities around the world, brown reveals what gardening can teach us about creating lives of compassion, connection and grace.
Can a bird that symbolizes death help the living catch criminals? In this informative and accessible talk, forensic anthropologist Lauren Pharr shows us how vultures impact crime scenes — and the assistance they can provide to detectives investigating murders. (This talk contains graphic images.)
What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" — a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it — which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.
Truth comes from the collision of different ideas, and theater plays an essential role in showing us that truth, says legendary artistic director Oskar Eustis. In this powerful talk, Eustis outlines his plan to reach (and listen to) people in places across the US where the theater, like many other institutions, has turned its back — like the deindustrialized Rust Belt. "Our job is to try to hold up a vision to America that shows not only who all of us are individually, but that welds us back into the commonality that we need to be," Eustis says. "That's what the theater is supposed to do."
Public libraries have always been about more than just books — and their mission of community support has taken on new urgency during the current opioid epidemic. After witnessing overdoses at her library in Philadelphia, Chera Kowalski learned how to administer naloxone, a drug that reverses the effects of narcotics, and she's put it to use to save patrons' lives. In this personal talk, she shares the day-to-day reality of life on the frontline of the opioid crisis and advocates for each of us to find new ways to keep our communities safe and healthy.
How does a city become known as a "music city"? Publicist Elizabeth Cawein explains how thriving music scenes make cities healthier and happier and shares ideas for bolstering your local music scene — and showing off your city's talent to the world.
If you think democracy is broken, here's an idea: let's replace politicians with randomly selected people. Author and activist Brett Hennig presents a compelling case for sortition democracy, or random selection of government officials — a system with roots in ancient Athens that taps into the wisdom of the crowd and entrusts ordinary people with making balanced decisions for the greater good of everyone. Sound crazy? Learn more about how it could work to create a world free of partisan politics.
Can technology make people safer from threats like violent extremism, censorship and persecution? In this illuminating talk, technologist Yasmin Green details programs pioneered at Jigsaw (a unit within Alphabet Inc., the collection of companies that also includes Google) to counter radicalization and online harassment — including a project that could give commenters real-time feedback about how their words might land, which has already increased spaces for dialogue. "If we ever thought that we could build an internet insulated from the dark side of humanity, we were wrong," Green says. "We have to throw our entire selves into building solutions that are as human as the problems they aim to solve."
What if we could save the fishing industry and protect the ocean at the same time? Marine ecologist Enric Sala shares his bold plan to safeguard the high seas — some of the last wild places on earth, which fall outside the jurisdiction of any single country — by creating a giant marine reserve that covers two-thirds of the world's ocean. By protecting the high seas, Sala believes we will restore the ecological, economic and social benefits of the ocean. "When we can align economic needs with conservation, miracles can happen," Sala says.
When facts are false, decisions are wrong, says editor and TED Fellow Olga Yurkova. To stop the spread of fake news, she and a group of journalists launched StopFake.org, which exposes biased or inaccurate reporting in order to rebuild the trust we've lost in our journalists, leaders and institutions. Learn more about the fight against misinformation as well as two critical ways we can ensure we're not reading (or sharing) fake news.
Our leaders and institutions are failing us, but it's not always because they're bad or unethical, says venture capitalist John Doerr — often, it's simply because they're leading us toward the wrong objectives. In this practical talk, Doerr shows us how we can get back on track with "Objectives and Key Results," or OKRs — a goal-setting system that's been employed by the likes of Google, Intel and Bono to set and execute on audacious goals. Learn more about how setting the right goals can mean the difference between success and failure — and how we can use OKRs to hold our leaders and ourselves accountable.
Dragonflies can catch prey with near perfect accuracy, the best among all predators. But how does something with so few neurons achieve such prowess? Our intrepid neuroscientists explore how a dragonfly unerringly locks onto its preys and captures it within milliseconds using just sensors and a fake fly.
Can you cram for a test while you sleep? Our intrepid neuroscientists attempt to enhance memory by running experiments on subjects while they sleep. You'll be surprised by the results.
Can the mind be manipulated to love a food we loathe? The evidence from fruit flies is compelling, and perhaps surprising. Our tag team of neuroscientists attempts to change a fly's preference for fruit over vegetables simply by shining a light on their brain.
Modern technology lets neuroscientists peer into the human brain, but can it also read minds? Armed with the device known as an electroencephalogram, or EEG, and some computing wizardry, our intrepid neuroscientists attempt to peer into a subject's thoughts.
What does the love song of a mosquito sound like? Find out as our intrepid neuroscientists explore the meaning of all that annoying buzzing in your ear.

In her brutally honest, ironically funny and widely read meditation on death, "You May Want to Marry My Husband," the late author and filmmaker Amy Krouse Rosenthal gave her husband Jason very public permission to move on and find happiness. A year after her death, Jason offers candid insights on the often excruciating process of moving through and with loss — as well as some quiet wisdom for anyone else experiencing life-changing grief.
Many artificial intelligence researchers expect AI to outsmart humans at all tasks and jobs within decades, enabling a future where we're restricted only by the laws of physics, not the limits of our intelligence. MIT physicist and AI researcher Max Tegmark separates the real opportunities and threats from the myths, describing the concrete steps we should take today to ensure that AI ends up being the best — rather than worst — thing to ever happen to humanity.
Robots are designed for speed and precision — but their rigidity has often limited how they're used. In this illuminating talk, biomedical engineer Giada Gerboni shares the latest developments in "soft robotics," an emerging field that aims to create nimble machines that imitate nature, like a robotic octopus. Learn more about how these flexible structures could play a critical role in surgery, medicine and our daily lives.
In a poetic, personal talk, TED Fellow Katlego Kolanyane-Kesupile examines the connection between her modern queer lifestyle and her childhood upbringing in a rural village in Botswana. "In a time where being brown, queer, African and seen as worthy of space means being everything but rural, I fear that we're erasing the very struggles that got us to where we are now," she says. "Indigenizing my queerness means bridging the many exceptional parts of myself."
Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we're a small part of a complex, four-billion-year process — and not the end of the line. "We're not the goal of evolution," Chakrabarty says. "Think of us all as young leaves on this ancient and gigantic tree of life — connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors."
When Gastón Acurio started his now world-famous restaurant Astrid & Gastón in the 1990s, no one suspected that he would elevate the Peruvian home-cooking he grew up with to haute cuisine. Nearly thirty years and a storied career later, the chef wants the rest of us to embrace our culinary roots and transform the world with the meals we prepare each day. (In Spanish with English subtitles)
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males — generosity, empathy, even peacekeeping — and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.
What happens when technology knows more about us than we do? Poppy Crum studies how we express emotions — and she suggests the end of the poker face is near, as new tech makes it easy to see the signals that give away how we're feeling. In a talk and demo, she shows how "empathetic technology" can read physical signals like body temperature and the chemical composition of our breath to inform on our emotional state. For better or for worse. "If we recognize the power of becoming technological empaths, we get this opportunity where technology can help us bridge the emotional and cognitive divide," Crum says.
The global refugee crisis is a mental health catastrophe, leaving millions in need of psychological support to overcome the traumas of dislocation and conflict. To undo the damage, child psychiatrist and TED Fellow Essam Daod has been working in camps, rescue boats and the shorelines of Greece and the Mediterranean Sea to help refugees (a quarter of which are children) reframe their experiences through short, powerful psychological interventions. "We can all do something to prevent this mental health catastrophe," Daod says. "We need to acknowledge that first aid is not just needed for the body, but it has also to include the mind, the soul."
Netflix changed the world of entertainment — first with DVD-by-mail, then with streaming media and then again with sensational original shows like "Orange Is the New Black" and "Stranger Things" — but not without taking its fair share of risks. In conversation with TED curator Chris Anderson, Netflix co-founder and CEO Reed Hastings discusses the company's bold internal culture, the powerful algorithm that fuels their recommendations, the $8 billion worth of content they're investing in this year and his philanthropic pursuits supporting innovative education, among much more.
What can we learn from the slimy, smelly side of life? In this playful talk, science journalist Anna Rothschild shows us the hidden wisdom of "gross stuff" and explains why avoiding the creepy underbelly of nature, medicine and technology closes us off to important sources of knowledge about our health and the world. "When we explore the gross side of life, we find insights that we never would have thought we'd find, and we even often reveal beauty that we didn't think was there," Rothschild says.
Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From "surprise egg" reveals and the "Finger Family Song" to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds — and they tell us something about where our increasingly data-driven world is headed. "We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them," Bridle says.
There's a creeping sameness in many of our newest urban buildings and streetscapes, says architect Vishaan Chakrabarti. And this physical homogeneity — the result of regulations, mass production, safety issues and cost considerations, among other factors — has blanketed our planet in a social and psychological homogeneity, too. In this visionary talk, Chakrabarti calls for a return to designing magnetic, lyrical cities that embody their local cultures and adapt to the needs of our changing world and climate.
Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery — from branding irons and shackles to postcards depicting lynchings — Rucker couldn't find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. "If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us," Rucker says. (This talk contains graphic images.)
Bridges need to be functional, safe and durable, but they should also be elegant and beautiful, says structural engineer Ian Firth. In this mesmerizing tour of bridges old and new, Firth explores the potential for innovation and variety in this essential structure — and how spectacular ones reveal our connectivity, unleash our creativity and hint at our identity.
In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet — a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" — raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.
The United States accounts for five percent of the world's population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids aren't equipped with the tools to eventually get people off the meds.
Flight is about to get a lot more personal, says aviation entrepreneur Rodin Lyasoff. In this visionary talk, he imagines a new golden age of air travel in which small, autonomous air taxis allow us to bypass traffic jams and fundamentally transform how we get around our cities and towns. "In the past century, flight connected our planet," Lyasoff says. "In the next, it will reconnect our local communities."
Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered until the mid-1980s — but its ancient genetic code may hold clues to how we can reduce our dependence on fossil fuels.
Why do juveniles falsely confess to crimes? What makes them more vulnerable than adults to this shocking, counterintuitive phenomenon? Through the lens of Brendan Dassey's interrogation and confession (as featured in Netflix's "Making a Murderer" documentary), developmental psychology professor and researcher Lindsay Malloy breaks down the science underlying false confessions and calls for change in the way kids are treated by a legal system designed for adults.

Our planet has a carbon problem — if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do ... but at a vast scale. This detailed talk reviews both the promise and the pitfalls.
Jakob Magolan is here to change your perception of organic chemistry. In an accessible talk packed with striking graphics, he teaches us the basics while breaking the stereotype that organic chemistry is something to be afraid of.
The Chinese internet has grown at a staggering pace — it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been irrevocably elevated because of it, says South China Morning Post CEO Gary Liu. In a fascinating talk, Liu details how the tech industry in China has developed — from the innovative, like AI-optimized train travel, to the dystopian, like a social credit rating that both rewards and restricts citizens.
Africa's youth is coming of age rapidly, but job growth on the continent isn't keeping up. The result: financial insecurity and, in some cases, a turn towards insurgent groups. In a passionate talk, agricultural entrepreneur Kola Masha details his plan to bring leadership and investment to small farmers in Africa — and employ a rising generation.
There are about a hundred trillion microbes living inside your gut — protecting you from infection, aiding digestion and regulating your immune system. As our bodies have adapted to life in modern society, we've started to lose some of our normal microbes; at the same time, diseases linked to a loss of diversity in microbiome are skyrocketing in developed nations. Computational microbiologist Dan Knights shares some intriguing discoveries about the differences in the microbiomes of people in developing countries compared to the US, and how they might affect our health. Learn more about the world of microbes living inside you — and the work being done to create tools to restore and replenish them.
Biologist Dan Gibson edits and programs DNA, just like coders program a computer. But his "code" creates life, giving scientists the power to convert digital information into biological material like proteins and vaccines. Now he's on to a new project: "biological transportation," which holds the promise of beaming new medicines across the globe over the internet. Learn more about how this technology could change the way we respond to disease outbreaks and enable us to download personalized prescriptions in our homes.
At MIT, Dina Katabi and her team are working on a bold new way to monitor patients' vital signs in a hospital (or even at home), without wearables or bulky, beeping devices. Bonus: it can see through walls. In a mind-blowing talk and demo, Katabi previews a system that captures the reflections of signals like Wi-Fi as they bounce off people, creating a reliable record of vitals for healthcare workers and patients. And in a brief Q&A with TED curator Helen Walters, Katabi discusses safeguards being put in place to prevent people from using this tech to monitor somebody without their consent.

Williams explains why the yawning cultural chasm created by class conflict is at the root of political polarization and provides some pointers on how to step back from the brink.
Spindly trees, rusted gates, crumbling stone, a solitary mourner: these things come to mind when we think of cemeteries.

(Hint: appoint someone to be the devil's advocate in your life.)
What exactly is civility, and what does it require? In a talk packed with historical insights, political theorist Teresa Bejan explains how civility has been used as both the foundation of tolerant societies and as a way for political partisans to silence and dismiss opposing views. Bejan suggests that we should instead try for "mere civility": the virtue of being able to disagree fundamentally with others without destroying the possibility of a common life tomorrow. (This talk contains mature language.)
Some days, it feels like the only thing we can agree on is that we can't agree — on anything.

Hard work, resilience and grit lead to success, right? This narrative pervades the way we think, says economist Darrick Hamilton, but the truth is that our chances at economic security have less to do with what we do and more to do with the wealth position we're born into. Enter "baby bonds": trust accounts of up to $60,000 for every newborn, calibrated to the wealth of their family. Learn how this bold proposal could help us reduce inequality — and give every child personal seed money for important things like going to college, buying a home or starting a business. "Without capital, inequality is locked in," Hamilton says. "When it comes to economic security, wealth is both the beginning and the end."
