Should we redesign humans?

Dan Reisel studies the biology of change, including our ability to rewire our own brains. And he asks a big question: Instead of warehousing these criminals, shouldn't we be using what we know about the brain to help them rehabilitate? Put another way: If the brain can grow new neural pathways after an injury ... could we help the brain re-grow morality?

Bioethicist Paul Root Wolpe describes an astonishing series of recent bio-engineering experiments, from glowing dogs to mice that grow human ears. He asks: Isn't it time to set some ground rules? (Filmed at TEDxPeachtree.) Talk by Paul Root Wolpe.

What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient's hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone's innate ability to regenerate and produces vast quantities of bone tissue painlessly.

http://www.ted.com Surgeon Anthony Atala demonstrates an early-stage experiment that could someday solve the organ-donor problem: a 3D printer that uses living cells to output a transplantable kidney. Using similar technology, Dr. Atala's young patient Luke Massella received an engineered bladder 10 years ago; we meet him onstage.
