ON A QUEST TO REVIVE THE WOOLLY MAMMOTH, COLOSSAL BIOSCIENCES HAS CREATED A WOOLLY MOUSE

Summary from the TLDR newsletter

Colossal Biosciences has genetically engineered mice to have mammoth-like fur using CRISPR. The mices' fur is of a color, texture, and thickness that resembles a mammoth's fur. The woolly coat may enable the mice to survive in cold climates. While the company believes that it will be eventually possible to re-create the woolly mammoth, there are still a lot of technical hurdles ahead.
