Scientists created transgenic mice with woolly mammoth–like traits. But does it really bring us closer to bringing back woolly mammoths?

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 ...

According to researchers at the US biotechnology and genetic engineering company Colossal Biosciences, the mouse's creation is a key step towards the de-extinction of the woolly mammoth – not a ...

The team at genetics and biotech firm Colossal Biosciences have imbued rodents with thicker, woolly coats, golden fur and other cold-climate adaptations, all of which are key characteristics of the ...

The animals, the first to have been created by Colossal Biosciences, have fluffy coats and curly whiskers.

De-extinction — the science of resurrecting extinct species — is progressing in leaps and bounds. Here are six creatures that researchers could bring back to life.

The little rodents' genes were edited to exhibit traits associated with a woolly mammoth genome—including fluffy, dirty-blonde fur.

The company first unveiled its plan to “de-extinct” the woolly mammoth using genetic editing and surrogacy and return it to the tundra equipped with the biological traits that will allow it to ...

After Earth's worst mass extinction, surviving ocean animals spread worldwide. Stanford's model shows why this happened.

Pictured are two of Colossal's "woolly mice". Dallas-based biotech startup Colossal aims to bring the woolly mammoth back from extinction through genetic engineering. As part of that process, the ...

Dr. Bergland is a professor at Simmons University. Extinction troubled us long before we had a name for it. The original mascot for the loss of species, even before the concept was understood, was ...
