Although often glossed over, the human liver is a pretty amazing organ. Not just because it’s pretty much the sole thing that prevents our food from killing us, but also because it’s the only organ in ...

So they turned their attention to the Iberian ribbed newt, which can regenerate not only body parts that are cut off but parts of its heart as well. There they focused on a molecule known as ...
