An insect's ability to fly is perhaps one of the greatest feats of evolution.

James B. Glattfelder: Who controls the world?

TEDxZurich 2011

James B. Glattfelder: Who controls the world?

And complexity theory, it turns out, can reveal a lot about how the economy works. Glattfelder shares a groundbreaking study of how control flows through the global economy, and how concentration of power in the hands of a shockingly small number leaves us all vulnerable. (Filmed at TEDxZurich.)

TEDxWomen 2012

Zahra' Langhi: Why Libya's revolution didn't work -- and what might


In Libya, Zahra' Langhi was part of the "days of rage" movement that helped topple the dictator Gaddafi. But -- then what? In their first elections, Libyans tried an innovative slate of candidates, the "zipper ballot," that ensured equal representation from men and women of both sides. Yet the same gridlocked politics of dominance and exclusion won out. What Libya needs now, Langhi suggests, is collaboration, not competition; compassion, not rage.

iO Tillett Wright: Fifty shades of gay


Artist iO Tillett Wright has photographed 2,000 people who consider themselves somewhere on the LGBTQ spectrum and asked many of them: Can you assign a percentage to how gay or straight you are? Most people, it turns out, consider themselves to exist in the gray areas of sexuality, not 100% gay or straight. Which presents a real problem when it comes to discrimination: Where do you draw the line? (Filmed at TEDxWomen.)

TEDxGlasgow

Richard Weller: Could the sun be good for your heart?


Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests, sunlight may confer another surprising benefit too. New research by his team shows that nitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system.
