Colossal Biosciences, a Texas-based biotech company, is working on reviving extinct animals, including the woolly mammoth. As part of their research, they have genetically modified mice embryos to create a "colossal woolly mouse" with thick, woolly fur. This experiment is a step towards altering Asian elephants to develop mammoth-like characteristics.

However, some scientists question the project's goals. Christopher Preston from the University of Montana argues that this is not true resurrection, as it only modifies living animals.

Beth Shapiro, Colossal's chief scientist, explains that the cold-resistant genes already existed in mice and were simply combined. Despite their progress, the project faces major challenges, especially since Asian elephants, the planned genetic base, are already endangered.
