Scientists working to unlock the secrets of de-extinction recently announced what they say is a turning point for the movement: the creation of transgenic mice with long, luxurious golden locks of tufted fur inspired by the coats of woolly mammoths.
They’re called Colossal woolly mice. And yes, they are cute to boot.
Transgenic mice — those that have had their genomes altered through genetic engineering — are not new. But what’s novel is the ability to engineer eight edits across seven genes and to do so simultaneously in one animal. The researchers also note that across three experiments, each of which used different combinations of edits, the method worked
