Inspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. In her talk, she shows us how it's done.
The feeling of security and the reality of security don't always match, says computer-security expert Bruce Schneier. In his talk, he explains why we spend billions addressing news story risks, like the "security theater" now playing at your local airport, while neglecting more probable risks -- and how we can break this pattern.
Medical ethicist Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally -- or to control the next steps of human evolution, using genetic modification, to make ourselves smarter, faster, better. Neo-evolution is within our grasp. What will we do with it?
Ric Elias had a front-row seat on Flight 1549, the plane that crash-landed in the Hudson River in New York in January 2009. What went through his mind as the doomed plane went down? At TED, he tells his story publicly for the first time.

John Hunter puts all the problems of the world on a 4'x5' plywood board -- and lets his 4th-graders solve them. At TED2011, he explains how his World Peace Game engages schoolkids, and why the complex lessons it teaches -- spontaneous, and always surprising -- go further than classroom lectures can.
Can two countries at war dare to empathize with one another? Step by methodical step, sociologist Sam Richards gives his audience an extraordinary challenge: to allow a group of (mainly) Americans to understand -- not approve of, but understand -- the motivations of an Iraqi insurgent. A powerful talk.
Pioneering surgeon Susan Lim performed the first liver transplant in Asia. But a moral concern with transplants (where do donor livers come from ...) led her to look further, and to ask: Could we be transplanting cells, not whole organs? At the INK Conference, she talks through her new research, discovering healing cells in some surprising places.
Using wikis and digital fabrication tools, TED Fellow Marcin Jakubowski is open-sourcing the blueprints for 50 farm machines, allowing anyone to build their own tractor or harvester from scratch. And that's only the first step in a project to write an instruction set for an entire self-sustaining village (starting cost: $10,000).
When film critic Roger Ebert lost his lower jaw to cancer, he lost the ability to eat and speak. But he did not lose his voice. In a moving talk from TED2011, Ebert and his wife, Chaz, with friends Dean Ornish and John Hunter, come together to tell his remarkable story.
Local politics -- schools, zoning, council elections -- hit us where we live. So why don't more of us actually get involved? Is it apathy? Dave Meslin says no. He identifies 7 barriers that keep us from taking part in our communities, even when we truly care.
Backed by stunning illustrations, David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. This is "Big History": an enlightening, wide-angle look at complexity, life and humanity, set against our slim share of the cosmic timeline.
Jackson Browne plays a song about being on the ocean ... or really, being anywhere among passionate friends. (He started writing this song aboard Mission Blue Voyage, a Sylvia Earle-inspired conference about saving the ocean.) "If I could be anywhere," he sings, "anywhere right now, I would be here."

With humor and persistence, filmmaker Morgan Spurlock dives into the hidden but influential world of brand marketing, on his quest to make a completely sponsored film about sponsorship. (And yes, onstage naming rights for this talk were sponsored too. By whom and for how much? He'll tell you.)

In a zippy demo at TED U, AnnMarie Thomas shows how two different kinds of homemade play dough can be used to demonstrate electrical properties -- by lighting up LEDs, spinning motors, and turning little kids into circuit designers.

The full piece premiered a few weeks later (yes, on YouTube!).

"Puppets always have to try to be alive," says Adrian Kohler of the Handspring Puppet Company, a gloriously ambitious troupe of human and wooden actors.

When first discovered in 2010, the Stuxnet computer worm posed a baffling puzzle. Beyond its sophistication loomed a more troubling mystery: its purpose. Ralph Langner and team helped crack the code that revealed this digital warhead's final target. In a fascinating look inside cyber-forensics, he explains how -- and makes a bold (and, it turns out, correct) guess at its shocking origins.
Patricia Ryan is a longtime English teacher who asks a provocative question: Is the world's focus on English preventing the spread of great ideas in other languages? In other words: What if Einstein had to pass the TOEFL? It's a passionate defense of translating and sharing ideas.

Eythor Bender of Berkeley Bionics brings onstage two amazing exoskeletons, HULC and eLEGS -- robotic add-ons that could one day allow a human to carry 200 pounds without tiring, or allow a wheelchair user to stand and walk. It's a powerful onstage demo, with implications for human potential of all kinds.
