The lab mice, which have been modified to have shaggy fur and golden coats, are a demonstration of the kind of gene edits that the company hopes to perform on a much larger scale, modifying Asian ...

Colossal Biosciences engineered mice with long, woolly hair by editing seven genes. Scientists see potential for conservation but doubt true "de-extinction." The company may apply the technique to ...

On Tuesday, the team behind the plan to bring mammoth-like animals back to the tundra announced the creation of what it is calling wooly mice, which have long fur reminiscent of the woolly mammoth.

with brown fur on the upper body and white fur below. This mouse is active all day and loves seeds. Like most mice, it ...

Genetics at the service of de-extinction To create these "woolly mice," researchers modified seven genes, including six related to fur texture, length, and color. These genes were selected by ...

Other target genes included MC1R (melanocortin 1 receptor), which regulates melanin production, in order to produce mice with golden hair rather than the usual dark fur and a variant associated ...

the other has yellow fur and is destined to be obese and prone to disease. How can two mice sharing exactly the same DNA become so different? The answer lies in the epigenome, a kind of second ...

Colossal Biosciences, the company aiming to resurrect the extinct species through genetic engineering, has now made mice with “mammoth-like” fur, each with up to five genetic changes.
