Andrew Pelling is a biohacker, and nature is his hardware. His favorite materials are the simplest ones (and oftentimes he finds them in the garbage). Building on the cellulose structure that gives an apple its shape, he "grows" lifelike human ears, pioneering a process that might someday be used to repair body parts safely and cheaply. And he has some even wilder ideas to share ... "What I'm really curious about is if one day it will be possible to repair, rebuild and augment our own bodies with stuff we make in the kitchen," he says.
TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and much more.
