Scientists have created a “miracle mouse” that can regenerate amputated limbs or badly damaged organs, making it able to recover from injuries that would kill or permanently disable normal animals.

The experimental animal is unique among mammals in its ability to regrow its heart, toes, joints and tail.

The researchers have also found that when cells from the test mouse are injected into ordinary mice, they too acquire the ability to regenerate.

Awesome.

Next they'll inject some dogs- to see if they, too, can regenerate mouse parts.
Cue the torrent of 'mouse balls' jokes...

That's insane. Didn't they grow a human ear on mouse's back once? I'm interested to know how simliar humans and mice are. What makes mice such good candidates for experiments? I wonder what would happen if they injected the cells into say, a guinea pig.

Science rules.

What slightly worries me about regeneration, is that simpler animals can do it, but higher animals can't. So at some stage, we must have mutated to lose the ability. But regeneration seems so massively evolutionarily selective, that it's inexplicable why such a mutant outcompeted those who could regenerate -- unless losing regeneration conferred some other even more gigantic benefit, perhaps in increased resistance to cancer or in reduced birth defects. I'd want to see several generations of these mice live and die happily before I was convinced this was a Good Thing.

They are small, easy to pick up by the tail, don't eat much, and historically they vote against unionization by predictable margins.

Yeah, but will it have a second button?

And scientists just don't like them.
