The X-Man Wolverine can heal from most wounds, regenerating damaged tissue. Now scientists at the Wistar Institute at the University of Pennsylvannia have created mice that can regenerate amputated limbs or damaged vital organs.
"We have experimented with amputating or damaging several different organs, such as the heart, toes, tail and ears, and just watched them regrow," Professor Ellen Heber-Katz said. "It is quite remarkable. The only organ that did not grow back was the brain." We won't know if they have extended life spans for another several months. Apparently this ability is controlled by about a dozen genes and that humans have comparable ones.
So when mutant mice take over the earth, aim for the head.
