Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself ...

New research in PLOS Biology shows that zebrafish embryos activate regeneration programs in response to genetic developmental ...

Some animals, including yaks and Tibetan antelopes, thrive at high elevations where oxygen levels are low. In humans, however, insufficient oxygen during development can lead to problems such as ...

Researchers linked orange cat fur to a 5-kilobase DNA deletion near ARHGAP36, which may explain the trait's inheritance and ...

The established conservation practice of relocating animals from large, genetically diverse populations to small communities of inbred endangered species may risk introducing more damaging than ...

The secret to the naked mole-rats' extraordinarily long life may lie in subtle changes to just four amino acids, researchers report. According to a new study, evolutionary mutations in cGAS – an ...

We’re easing you into Halloween season with an episode about bats. There’s a silent serial killer decimating little brown ...

Every cell carries a molecular record of time. As DNA is copied, repaired and exposed to damage, mutations gradually accumulate — most harmless, some potentially consequential. A new Cell study found ...
