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 ...

In a groundbreaking study, scientists have created a mouse using stem cells powered by genes that originated from ancient ...

But the molecular cause of this switch is unknown. To solve that mystery, Harvard University stem cell biologist Ya-Chieh Hsu and her colleagues turned to mice. They first confirmed the effects of ...

Scientists created transgenic mice with woolly mammoth–like traits. But does it really bring us closer to bringing back woolly mammoths?

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 ...

The compound SCD-153 accelerates the regrowth of mouse fur compared to control experiments using a solvent and 4-methyl itaconate. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

A mouse gives birth to identical-twin sisters. One has brown fur and will grow up to be lean and healthy; the other has yellow fur and is destined to be obese and prone to disease. How can two ...

Deer mice construct spherical or cup-shaped nests of shredded plant fibers, fur, and feathers under logs, stumps, rocks in the abandoned dens of other mammals, but prefers natural cavities of tress.

Wild mice and laboratory mice differ in appearance, especially in coat colour. The wild forms usually have a brown coat, whereas albino laboratory strains have white fur and other strains have black ...
