Absolutely wild:

SCIENTISTS have created “miracle mice” that can regenerate amputated limbs or damaged vital organs, making them able to recover from injuries that would kill or permanently disable normal animals.

The experimental animals are unique among mammals in their ability to regrow their heart, toes, joints and tail.

And when cells from the test mouse are injected into ordinary mice, they too acquire the ability to regenerate, the US-based researchers say.

Their discoveries raise the prospect that humans could one day be given the ability to regenerate lost or damaged organs, opening up a new era in medicine.

[…] “It is quite remarkable. The only organ that did not grow back was the brain.

“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.”

This seems like huge news.
