Vivek Maru is working to transform the relationship between people and law, turning law from an abstraction or threat into something that everyone can understand, use and shape. Instead of relying solely on lawyers, Maru started a global network of...
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...
MIT grad student David Merrill demos Siftables -- cookie-sized, computerized tiles you can stack and shuffle in your hands. These future-toys can do math, play music, and talk to their friends, too. Is this the next thing in hands-on learning?
When Allison Hunt found out that she needed a new hip -- and that Canada’s national health care system would require her to spend nearly 2 years on a waiting list (and in pain) -- she took matters into her own hands.
Marco Tempest spins a beautiful story of what magic is, how it entertains us and how it highlights our humanity -- all while working extraordinary illusions with his hands and an augmented reality machine.
Surgeon and inventor Catherine Mohr tours the history of surgery (and its pre-painkiller, pre-antiseptic past), then demos some of the newest tools for surgery through tiny incisions, performed using nimble robot hands. Fascinating -- but not for the squeamish.

The world's population will grow to 9 billion over the next 50 years -- and only by raising the living standards of the poorest can we check population growth. This is the paradoxical answer that Hans Rosling unveils at TED@Cannes using colorful new data display technology (you'll see).

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.
In a series of witty punchlines, Patrick Chappatte makes a poignant case for the power of the humble cartoon. His projects in Lebanon, West Africa and Gaza show how, in the right hands, the pencil can illuminate serious issues and bring the most unlikely people together.
Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — ...
Researcher Hans Rosling uses his cool data tools to show how countries are pulling themselves out of poverty. He demos Dollar Street, comparing households of varying income levels worldwide. Then he does something really amazing.
Hans Rosling had a question: Do some religions have a higher birth rate than others -- and how does this affect global population growth? Speaking at the TEDxSummit in Doha, Qatar, he graphs data over time and across religions. With his trademark humor and sharp insight, Hans reaches a surprising conclusion on world fertility rates.
Hans Rosling was a young guest student in India when he first realized that Asia had all the capacities to reclaim its place as the world's dominant economic force. At TEDIndia, he graphs global economic growth since 1858 and predicts the exact date that India and China will outstrip the US.
