Some ... favorite gee-whiz moments from this year's TED conference: -- UC Berkeley biologist Robert Full blew everyone's mind by outlining his efforts to create the perfect robotic distributed foot." He studies the feet and legs of geckos and cockroaches and transfers their design to robots, enabling them to scale walls. One such machine, the Spinybot, can climb glass walls. -- P.W. Singer, an academic who studies war, terrified the crowd with a detailed look at modern, robotic warfare. Something I didn't know: You can sit in a room in New Mexico and pilot armed drone airplanes in Iraq and kill people. Then you go home and have dinner with your kids. Somewhere, Aldous Huxley weeps. -- Stanford's Catherine Mohr displayed the robotic surgical arm she's working on that could change medicine. Among the amazing possibilities are surgeons in the United States performing advanced surgeries in remote parts of the world. These are just a handful of the amazing innovations and disclosures made at TED this year. In the coming weeks and months, videos of all of these talks will be made available to the public at www.ted.com. TED, which stands for Technology, Entertainment, Design, is a 25-year-old annual conference attended by many of the world's leading scientists, academics and business leaders. The agenda consists of a series of talks, during which big thinkers discuss big ideas.
