You've heard of the woolly mammoth. But have you heard of woolly mice? These critters were genetically modified by the Dallas-based biotech company <a href="https://colossal.com/">Colossal Biosciences</a> to have the same "woolly" and fat appearance as the ancient mammoths. The mice are a key step in the longer journey to de-extinct the woolly mammoth. NPR's <a href="https://www.npr.org/people/146944972/rob-stein">Rob Stein</a> takes us to the lab where it all happened.
