New research shows 'promising' results for hair loss treatment using stem cells and other injections, with 100% of male mice experiencing significant hair regrowth.

Researchers at San Carlos Clinical Hospital in Madrid have developed a cure for androgenetic alopecia — commonly known as pattern hair loss.

On Tuesday, Colossal announced that its scientists have simultaneously edited seven genes in mice embryos to create mice with long, thick, woolly hair.

Scientists began with mice to see if the process works before possibly moving on to edit embryos of Asian elephants, the woolly mammoth's closest living relative.

By combining three editing technologies, Colossal engineered mice that express multiple mammoth-identified traits relevant to cold adaptation.
