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

A US biotech company has genetically modified mice to have traits from the extinct woolly mammoth. Researchers at Colossal ...

Take the latest discovery by scientists at Colossal Biosciences in Dallas, Texas, who recently bred “woolly mice.” How cool!

Scientists at Colossal Biosciences have genetically engineered mice to exhibit long, thick, woolly hair reminiscent of the ...

Following U.S. President Donald Trump's address to Congress on Mar. 4, 2025, a rumor circulated online that he misspoke when ...

Scientists working to bring back the woolly mammoth have created genetically engineered mice that they say have several ...

US start-up Colossal Biosciences says it is on track to produce a woolly mammoth calf born to a surrogate elephant mother by ...

Raising and breeding the hybrid animals, they say, could imperil living animals used as surrogates. “While we know a lot about mouse genetics, we know much less about mammoths and elephants.

Therefore, the researchers have chosen mice for the initial experiments. Mice breed quickly, and their genes are easier to modify, which allows scientists to test and refine their methods in an ...

However, by comparing datasets of mammoth and elephant genomes, the team identified that mammoths lost the function of one of these genes. The researchers also introduced mutations into two of the ...
