A mouse injured on one leg experiences an "awakening" of stem cells in the other leg as if the cells are preparing to heal an injury. Something similar happens in axolotls, which are masters at limb regeneration. Heart injuries ...

Planarians are flatworms with the extraordinary ability to restore wounded or missing parts of their body. It has long been known that a particular group of proteins—known as PIWI proteins—are essential for this ability ...

Slice it into a hundred pieces if you want, and the millimeters-long flatworm called a planarian won't particularly care. Each piece can grow back into a new worm. But how they do that, and what scientists could learn about ...

When it comes to regeneration, some animals are capable of amazing feats—if you cut the leg off a salamander, it will grow back. When threatened, some geckos drop their tails as a distraction, and regrow them later.
