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.<\/p>\n\n\n\n

They\u2019re called Colossal woolly mice. And yes, they are cute to boot.<\/p>\n\n\n\n

Transgenic mice \u2014 those that have had their genomes altered through genetic engineering \u2014 are not new. But what\u2019s 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 with high efficiency, resulting in living animals that presented the traits they were bred for.<\/p>\n\n\n
