Scientists have created genetically engineered "woolly mice" with fur similar to the thick hair that kept woolly mammoths warm during the last ice age.
The biotechnology company Colossal Biosciences unveiled images and footage of the woolly mice on Tuesday (March 4). The adorable rodents mark a milestone in Colossal's project to bring back woolly mammoths by 2028, the company said in a statement shared with Live Science.
