This was an alarming start to the idea of gene de-extinction. As we know from movies like The Thing, digging up frozen creatures from the ice is a bad idea. Many scientists felt that recovering the 1918 flu—which had killed 30 million people—created an unnecessary risk that the virus could slip loose, setting off a new outbreak.

This week saw the release of some fascinating news about some very furry rodents— so-called “woolly mice ”—created as part of an experiment to explore how we might one day resurrect the woolly mammoth.

It will take a lot more genetic science than a few tweaks to hair length to make a mammoth from its closest living relative, the Asian elephant.

Colossal Biosciences has focused on identifying key traits of extinct animals by studying ancient DNA, with a goal to genetically "engineer them into living animals," said CEO Ben Lamm.

Colossal Biosciences has raised over $400 million to bring the woolly mammoth back from extinction, and is betting on lucrative spinoff innovations.

The mice were created by Colossal Biosciences, which edits DNA for species conservation, and has been working to bring back the woolly mammoth since 2021.

The biotech company Colossal Biosciences has long aspired to bring back the extinct woolly mammoth, which roamed the Northern Hemisphere thousands of years ago, during the last ice age. But for now, as a step along the way, the company has come up with something decidedly less mammoth: meet the woolly mouse.

Colossal Biosciences announced Tuesday that it has simultaneously edited seven genes in mice embryos to create mice with long, thick, woolly hair.

It’s one small step for mice, one giant leap for mammoth-kind. Scientists endeavoring to “de-extinct” woolly mammoths through genetic modification have taken a meaningful step toward achieving their goal — creating an entirely new species called the woolly mouse.

A US biotech company has genetically modified mice to have traits from the extinct woolly mammoth. Researchers at Colossal Laboratories and Biosciences endowed their mice with the thick, shaggy hair of the mammoth and its efficient fat metabolism, which helped it survive in icy conditions.
