This is probably the most sensational and science-fiction-like scientific discovery I've seen since my post on invisibility. Scientists have created miracle mice that can regenerate amputated limbs and damaged internal organs. They can regrow limbs, joints, and even hearts. This is amazing in that it's the first time such abilities have been developed in mammals. I for one welcome our new rodent overlords. [1]
With this discovery, I can easily imagine such traits being migrated to humans within my lifetime. And here's the most amazing part.
"When we injected fetal liver cells taken from those animals into ordinary mice, they too gained the power of regeneration. We found this persisted even six months after the injection."
It might as well be promicin.
