Regenerative mice

Not sure how many people saw this on Slashdot, but apparently all those biologists may have some use after all (even the French PhD's with biology leanings). A group at Penn State has apparently created mice that can regenerate limbs and internal organs and even have even found ways to pass this ability on to other mice via cell transfer. Maybe one day I'll be able to have a couple of extra hands grown so I can type twice as fast-- think of the productivity gains.
