Scientists looking to bring the woolly mammoth back to life have used gene editing to create a "woolly mouse." It has ...

In 2010 Yukaghir hunters found the nearly intact carcass of a young woolly mammoth frozen in the northern Siberian permafrost. With its reddish-brown fur still clinging to its skin, the dog-sized calf ...

A group of South Korean and Russian scientists are planning to bring the woolly mammoth back to life, 10,000 years after the species went extinct. Using tissue samples from the specimens recovered in ...

A 40,000-year-old juvenile woolly mammoth named Yuka is not only remarkable because she was uncovered nearly intact or her grisly cause of death. Her muscles provided paleogeneticists with the oldest ...

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 ...

It’s one small step for mice, one giant leap for mammoth-kind. Scientists endeavoring to “de-extinct” woolly mammoths through genetic modification have taken a meaningful step toward achieving their ...

Long before global warming was the biggest environmental issue, the planet was in the opposite kind of funk — an ice age lasting around 2.6 million years. During this time, starting about 700,000 ...

The idea of bringing extinct species back to life sounds like something out of a sci-fi movie. But researchers at Colossal Biosciences are committed to doing it. Using high-tech genetic engineering, ...

In the final moments of Yuka the woolly mammoth’s life, he may have been trying to outsprint a cave lion. Yuka’s hind legs bear scratches — and in his muscle tissue, scientists have detected molecular ...
