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.
“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?
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.
Luke Syson was a curator of Renaissance art, of transcendent paintings of saints and solemn Italian ladies -- Very 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 ...
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.
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.
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.
In this lovely talk, TED Fellow Ryan Holladay shares his experiment with "location-aware music." This programming and musical feat involves hundreds of geotagged segments of sounds that only play when a listener is physically nearby, creating a magical sense of presence.
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, 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 1,000 years.
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.
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.
"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.
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.
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.
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.
"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.
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.
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.
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."
"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.
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.
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.
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.
"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 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.
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.
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.)
It's relatively easy to imagine a new medicine -- the hard part 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 -- perhaps even custom cures made for one specific person.
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.
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.
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.
