Épisode 126 - Lesley Hazleton: The doubt essential to faith

24 juin 2013

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.

Épisode 127 - Peter Attia: Is the obesity crisis hiding a bigger problem?

25 juin 2013

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.

Épisode 129 - Michael Archer: How we'll resurrect the gastric brooding frog, the Tasmanian tiger

27 juin 2013

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.

Épisode 130 - Rodney Brooks: Why we will rely on robots

28 juin 2013

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.

Épisode 131 - Eric X. Li: A tale of two political systems

Épisode 132 - Joel Selanikio: The surprising seeds of a big-data revolution in healthcare

2 juillet 2013

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.)

Épisode 133 - Jinha Lee: Reach into the computer and grab a pixel

Épisode 134 - Sleepy Man Banjo Boys: Bluegrass virtuosity from ... New Jersey?

5 juillet 2013

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.

Épisode 139 - Al Vernacchio: Sex needs a new metaphor. Here's one …

12 juillet 2013

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.

Épisode 140 - Bernie Krause: The voice of the natural world

15 juillet 2013

22 juillet 2013

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.)

Épisode 148 - Paul Kemp-Robertson: Bitcoin. Sweat. Tide. Meet the future of branded currency.

25 juillet 2013

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.

Épisode 151 - Eli Beer: The fastest ambulance? A motorcycle

30 juillet 2013

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.

Sit back and let the wall of sound of this dazzling performance wash over you.

Épisode 155 - Daniel H. Cohen: For argument’s sake

5 août 2013

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.)

Épisode 158 - Eleanor Longden: The voices in my head

8 août 2013 - 5/5

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.

5 septembre 2013

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.

Épisode 168 - Alexa Meade: Your body is my canvas

6 septembre 2013

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.

Épisode 169 - George Monbiot: For more wonder, rewild the world

9 septembre 2013

Wolves were once native to the US' Yellowstone National Park — until hunting wiped them out.

Épisode 185 - Kelli Swazey: Life that doesn't end with death

1 octobre 2013

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.)

Épisode 186 - Amy Webb: How I hacked online dating

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.

Épisode 189 - Michael Porter: Why business can be good at solving social problems

7 octobre 2013

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.

Épisode 190 - Michael Sandel: Why we shouldn't trust markets with our civic life

7 octobre 2013

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?

Épisode 191 - Janette Sadik-Khan: New York's streets? Not so mean any more

Épisode 192 - Trita Parsi: Iran and Israel: Peace is possible

9 octobre 2013

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.

Épisode 193 - Gary Slutkin: Let's treat violence like a contagious disease

10 octobre 2013

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.

Épisode 194 - Andrew Fitzgerald: Adventures in Twitter fiction

11 octobre 2013

Épisode 195 - Jeff Speck: The walkable city

14 octobre 2013

Épisode 196 - Amanda Bennett: We need a heroic narrative for death

15 octobre 2013

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.

Épisode 197 - Iwan Baan: Ingenious homes in unexpected places

16 octobre 2013

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.

Glorious images celebrate humanity's ability to survive and make a home -- anywhere.

Épisode 198 - Alessandro Acquisti: What will a future without secrets look like?

17 octobre 2013

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.

Épisode 199 - Hetain Patel: Who am I? Think again

Épisode 200 - Steve Howard: Let's go all-in on selling sustainability

21 octobre 2013

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.

Épisode 201 - Charles Robertson: Africa's next boom

22 octobre 2013

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.

Épisode 202 - Parul Sehgal: An ode to envy

23 octobre 2013 - 4/5

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.

Épisode 203 - Gian Giudice: Why our universe might exist on a knife-edge

24 octobre 2013

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.

Épisode 204 - Xavier Vilalta: Architecture at home in its community

25 octobre 2013

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.

Épisode 205 - Mariana Mazzucato: Government -- investor, risk-taker, innovator

28 octobre 2013

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.

Épisode 206 - Mohamed Hijri: A simple solution to the coming phosphorus crisis

29 octobre 2013

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.)

Épisode 207 - Abha Dawesar: Life in the "digital now"

30 octobre 2013

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?

Épisode 208 - Holly Morris: Why stay in Chernobyl? Because it's home.

31 octobre 2013

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."

Épisode 209 - Dong Woo Jang: The art of bow-making

1 novembre 2013

Épisode 210 - Rodrigo Canales: The deadly genius of drug cartels

4 novembre 2013

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.

Épisode 211 - Robin Nagle: What I discovered in New York City trash

5 novembre 2013

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?

Épisode 212 - Grégoire Courtine: The paralyzed rat that walked

6 novembre 2013

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.

Épisode 213 - Mikko Hypponen: How the NSA betrayed the world's trust

7 novembre 2013

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.

Épisode 214 - Arthur Benjamin: The magic of Fibonacci numbers

Épisode 215 - Dambisa Moyo: Is China the new idol for emerging economies?

11 novembre 2013

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.

Épisode 216 - Chris Downey: Design with the blind in mind

12 novembre 2013

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.

Épisode 217 - Mohamed Ali: The link between unemployment and terrorism

13 novembre 2013

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.

Épisode 218 - Stefan Larsson: What doctors can learn from each other

14 novembre 2013

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?

Épisode 219 - Jane McGonigal: Massively multi-player… thumb-wrestling?

15 novembre 2013

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?

Épisode 220 - Lian Pin Koh: A drone's-eye view of conservation

18 novembre 2013

Ecologist Lian Pin Koh makes a persuasive case for using drones to protect the world's forests and wildlife.

They're also entirely affordable.

Épisode 221 - Greg Asner: Ecology from the air

19 novembre 2013

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.

Épisode 222 - Henry Evans and Chad Jenkins: Meet the robots for humanity

20 novembre 2013

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.)

Épisode 223 - Andreas Raptopoulos: No roads? There’s a drone for that

21 novembre 2013

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.

Épisode 224 - How your "working memory" makes sense of the world

22 novembre 2013

"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."

Épisode 225 - Jared Diamond: How societies can grow old better

25 novembre 2013

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.

Épisode 226 - Suzana Herculano-Houzel: What is so special about the human brain?

26 novembre 2013

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.

Épisode 227 - David Steindl-Rast: Want to be happy? Be grateful

27 novembre 2013

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.

Épisode 228 - Toby Eccles: Invest in social change

2 décembre 2013

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.

Épisode 229 - Geraldine Hamilton: Body parts on a chip

3 décembre 2013

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)

Épisode 230 - Sally Kohn: Let’s try emotional correctness

4 décembre 2013

It's time for liberals and conservatives to transcend their political differences and really listen to each other, says political pundit Sally Kohn.

Épisode 235 - Eddy Cartaya: My glacier cave discoveries

11 décembre 2013

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.

Épisode 236 - Stephen Cave: The 4 stories we tell ourselves about death

12 décembre 2013

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."

Épisode 237 - Rose George: Inside the secret shipping industry

13 décembre 2013

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.

Épisode 238 - Toni Griffin: A new vision for rebuilding Detroit

16 décembre 2013

Épisode 239 - Marco Annunziata: Welcome to the age of the industrial internet

17 décembre 2013

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.

Épisode 240 - Andrew Solomon: Depression, the secret we share

18 décembre 2013

"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.)

Épisode 241 - Krista Donaldson: The $80 prosthetic knee that's changing lives

19 décembre 2013

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.

Épisode 242 - Paul Piff: Does money make you mean?

20 décembre 2013

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.

Épisode 4 - Roger Stein: A bold new way to fund drug research

7 janvier 2014

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.)

Épisode 8 - Harish Manwani: Profit’s not always the point

13 janvier 2014

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.

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.

Épisode 10 - Sheryl Sandberg: So we leaned in ... now what?

15 janvier 2014

16 janvier 2014

Luke Syson was a curator of Renaissance art, of transcendent paintings of saints and solemn Italian ladies — serious art.

Épisode 13 - Shereen El Feki: A little-told tale of sex and sensuality

21 janvier 2014

“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?

Épisode 14 - Paula Johnson: His and hers … healthcare

22 janvier 2014

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.

Épisode 108 - Margaret Heffernan: Why it's time to forget the pecking order at work

17 juin 2015

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.”

Épisode 109 - Steve Silberman: The forgotten history of autism

18 juin 2015

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.)

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.

Épisode 125 - Aspen Baker: A better way to talk about abortion

14 juillet 2015

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.

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.)

How did we get from there to here? Historian Yuval Noah Harari suggests a surprising reason for the rise of humanity.

10 août 2015

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.

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.

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.

Épisode 187 - Daniel Levitin: How to stay calm when you know you'll be stressed

30 octobre 2015

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.

"We all are going to fail now and then," he says. "The idea is to think ahead to what those failures might be."

Épisode 194 - Andreas Ekström: The moral bias behind your search results

10 novembre 2015

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."

"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.
