Scientists at biotech company Colossal Biosciences were able to produce genetically modified mice, a successful feat in their ongoing conservation and de-extinction efforts.

Scientists working to bring back the woolly mammoth have created genetically engineered mice that they say have several features of the extinct ice age giant.

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.

De-extinction company Colossal mixed mammoth and mouse mutations in a single strain to create a shaggy-haired rodent.

The de-extinction company Colossal Biosciences wants to bring back the woolly mammoth—starting with a very furry mouse.

US biotechnology company Colossal Laboratories and Biosciences has a radical proposal: it wants to resurrect the woolly mammoth from extinction. In a preprint paper published on March 4, scientists at Colossal report making a significant step towards this objective.

The last time we wrote about biotechnology firm Colossal was in 2021, when they’d announced an impressive fundraising haul as part of their stated mission to bring back a number of extinct animals, including the wooly mammoth.
