Regrowing Human Limbs
By Virginia Prescott on Tuesday, March 25, 2008.
listen:
Five years of war in Iraq - and the physical wounds that go along with it - have led to a renaissance of sorts in the field of high-tech artificial limbs. But some researchers are working on a much more radical solution for amputees: limb regeneration. 
When a salamander loses a leg, a new one grows back automatically. Scientists are trying to figure out if they can unlock the same potential in human beings. John Rennie is the editor-in-chief of Scientific American, which just published an article about limb regeneration. He joins Word of Mouth host Virginia Prescott to talk about it.

Saw an interesting video a while back that tied into phantom limbs. Worth watching the whole video by this guy: http://www.ted.com/index.php/talks/view/id/184
He covers three different topics on the brain. The phantom limb piece specifically connects the feelings of phantom limbs to visual triggers.
I wonder whether there would be the same outcry to limb regeneration as cloning or stem cells. Though it's part of your body, I could easily anticipate arguments being made against it.
