Playlist (11 talks): The world of tiny things 12:06Now playingWhen photographed under a 3D microscope, grains of sand appear like colorful pieces of candy and the stamens in a flower become like fantastical spires at an amusement park. Gary Greenberg reveals the thrilling details of the micro world. 14:09Now playingEcologist Deborah Gordon studies ants wherever she can find them — in the desert, in the tropics, in her kitchen ... In this fascinating talk, she explains her obsession with insects most of us would happily swat away without a second thought. She argues that ant life provides a useful model for learning about many other topics, including disease, technology and the human brain. 19:43Now playingWillard Wigan tells the story of how a difficult and lonely childhood drove him to discover his unique ability — to create art so tiny that it can't be seen with the naked eye. His slideshow of figures, as seen through a microscope, can only be described as mind-boggling. 18:14Now playingBonnie Bassler discovered that bacteria "talk" to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry — and our understanding of ourselves. 22:35Now playingAs E.O. Wilson accepts his 2007 TED Prize, he makes a plea on behalf of all creatures that we learn more about our biosphere — and build a networked encyclopedia of all the world's knowledge about life. 5:31Now playingMark Shaw demos Ultra-Ever Dry, a liquid-repellent coating that acts as an astonishingly powerful shield against water and water-based materials. At the nano level, the spray covers a surface with an umbrella of air so that water bounces right off. Watch for an exciting two-minute kicker. 9:08Now playingWe have no ways to directly observe molecules and what they do — Drew Berry wants to change that. In this talk, he shows his scientifically accurate (and entertaining!) animations that help researchers see unseeable processes within our own cells. (Filmed at TEDxSydney.) 19:06Now playingPhysicist Brian Greene explains superstring theory, the idea that minscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. 9:45Now playingMedical animator David Bolinsky presents 3 minutes of stunning animation that show the bustling life inside a cell. 13:23Now playingIt's relatively easy to imagine a new medicine, a better cure for some disease. The hard part, though, is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications — even custom cures for one specific person. (Filmed at TEDxBoston) 16:24Now playingIn 2007, Paul Rothemund gave TED a short summary of his specialty, DNA folding. Now he lays out in clear, abundant detail the immense promise of this field — to create tiny machines that assemble themselves.

Debra Gordon (Deborah Gordon): Čemu nas mravi uče o mozgu, raku i internetu Ekolog Debra Gordon proučava mrave gde god da ih nađe - u pustinji, u tropskim krajevima, u svojoj kuhinji... U ovom fascinantnom govoru, ona objašnjava svoju opsesiju insektima koje bi većina nas rado zgnječila bez imalo razmišljanja. Ona tvrdi da mravlji život pruža koristan model za učenje o mnogim drugim temama, uključujući bolest, tehnologiju i ljudski mozak.
