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.
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.
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.
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. He hopes his films can help people see their own cultures in a new way, to make young people say: "Whoa, my grandfather is as cool as Beyoncé." Followed by a mesmerizing performance by jazz icon Naná Vasconcelos.
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.
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.
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.
In this intriguing talk, biologist Ameenah Gurib-Fakim introduces us to rare plant species from isolated islands and regions of Africa.

It’s a bold argument about the future of politics and power; watch and see if you agree.
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.
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.
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.
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.
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.
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.
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.
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.
Today's refugee crisis is the biggest since World War II, and it's growing. When this talk was given, 50 million people had been forcefully displaced from their homes by conflict and war; now the number is 65.3 million. There were 3 million Syrian refugees in 2014; now there are 4.9 million. Inside this overwhelming crisis are the individual human stories -- of care, growth and family, in the face of lost education, lost home, lost future. Melissa Fleming of the UN's refugee agency tells the refugees' stories -- and asks us to help them rebuild their world.
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.
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.
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."
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."
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.
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.
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.
