The journey to the woolly mouse began with the woolly mammoth. Scientists at Colossal examined more than 100 genomes of Asian elephants and woolly mammoths.

Colossal Biosciences, a Dallas-based company focused on de-extinction, has unveiled its latest success: golden, long-haired mice. Affectionately dubbed woolly mice, these curly cuties mark an ...

The Colossal Woolly Mouse, born in October 2024, was genetically engineered to have characteristics that could eventually be used in creating a next-generation woolly mammoth embryo to be born by ...

However, the "woolly mice" with the mammoth-style variant of FABP2 did not show significant differences in body mass compared to regular lab mice. What would it mean to de-extinct a species?

Scientists began with mice to see if the process works before possibly moving on to edit embryos of Asian elephants, the woolly mammoth's closest living relative.

Behold, the woolly mouse. Scientists at the Dallas-based Colossal Biosciences have taken a small step towards their goal of bringing back the woolly mammoth: Colossal Woolly Mouse.

The term de-extinction is inaccurate, but conservation is still the best way to achieve its stated goals. We need to save the ...

They nicknamed the extra-furry rodents as the "Colossal woolly mouse." Colossal Biosciences say they have edited seven genes in mice embryos to create mice with long, thick, woolly hair.

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.

On Tuesday, Colossal announced that its scientists have simultaneously edited seven genes in mice embryos to create mice with long, thick, woolly hair. They nicknamed the extra-furry rodents as ...
