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 scientists modified ten genes in total in their mice, in different combinations. Interestingly, only three were changed to resemble genes found in the woolly mammoth.

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. They lined up those genomes side by ...

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 ...

Colossal Biosciences engineered mice with long, woolly hair by editing seven genes. Scientists see potential for conservation but doubt true "de-extinction." The company may apply the technique to ...

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 ...

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.

Other researchers say the woolly mice are exciting. “I’m pretty skeptical about this, but that mouse is pretty adorable,” says Vincent Lynch, a professor of biology at the University at Buffalo.
