Dire wolves went extinct about 12,000 years ago. In April, biotech company Colossal Biosciences announced it had cloned three pups that resemble the long-dead creatures. Scientists used DNA from a 13,000-year-old tooth and a 72,000-year-old skull to make 15 key edits to the gray wolf genome and recreate dire wolf traits. Expected to grow to twice the size of gray wolves, the pups have wider heads, larger jaws, and stronger shoulders. The Mandan,…

Trying to Bring Mammoths Back to Life, Scientists Create a Strange New Creature

In a laboratory in Dallas, Texas, researchers at Colossal Biosciences have taken a striking step toward reviving one of the Earth’s most iconic lost creatures: the woolly mammoth. Using advanced gene-editing techniques, scientists have bred mice with long, woolly fur and unique metabolic traits modeled on the extinct mammoth, aiming to perfect a method that could ultimately bring back the species by 2028. A Surprising Model for an Ancient Giant …
