TED2011: Scientists Create Organ 'Copies' in Just Seven Hours

Hemera Technologies/Thinkstock(LONG BEACH, Calif.) -- Welcome to TED, where the world's great minds come to dream the impossible and show that it's happening. This week in Long Beach, Calif., the room gasped at the sight of something that could revolutionize medicine: organs created, in effect, as Xerox copies.

Dr. Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine, has spent 30 years studying the ability to grow and regenerate human tissue. Stepping onto the TED2011 stage Thursday for his 18-minute talk, he put out his hand and said, "And here it is, you can actually see the human kidney, as it was printed earlier today."

In just seven hours, Wake Forest scientists created a functioning human kidney, using cells regenerated from a sample of the patient's living cells. A machine separated out the cells that specialized into kidney cells, which then were grown in a lab and layered on top of one another until they were sculpted into a kidney.

The scientists call it "printing."

Dr. Atala was just one of the 50 or so speakers to present their great ideas over the four-day conference.

Five years ago, TED, a nonprofit organization devoted to "ideas worth spreading," started taking some of these great lectures and putting them online for free. No speaker is ever allowed to go more than 18 minutes -- just 18 minutes to share the next great idea.

Chris Anderson, the curator of the TED conference, said the time limit is "long enough to say something serious, but short enough not to lose your audience."

Microsoft founder Bill Gates, who spoke at TED this week, said "by forcing that speaker to boil it down, to capture the essence ... it's inspirational, it's educational."
