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.
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.
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.
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 cracking up.
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.
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."
How did a young man born into a high caste in India come to free 83,000 children from slavery?

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.
As manager of the Rosetta mission, Fred Jansen was responsible for the successful 2014 landing of a probe on the comet known as 67P/Churyumov-Gerasimenko.

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."
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.
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."
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 shows how this works -- and asks us all to let go of our fear of the dark unknown.

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.
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 a thrilling talk, computer vision expert Fei-Fei Li describes the state of the art -- including the database of 15 million photos her team built to "teach" a computer to understand pictures -- and the key insights yet to come.
"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.
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?
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.
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.
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.
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.
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.
