Colossal Biosciences has revealed the world's first 'woolly mice', after engineering rodents to grow thick, warm coats using mammoth DNA.
Scientists at Colossal Biosciences have genetically engineered mice with thick, fluffy coats by introducing mammoth DNA, specifically targeting genes related to hair and lipid metabolism. The resulting "woolly mice" exhibit longer, curlier, and differently colored fur, demonstrating the potential for applying similar techniques to de-extinction efforts, potentially paving the way for bringing back the woolly mammoth.
