A mouse injured on one leg experiences an "awakening" of stem cells in the other leg as if the cells are preparing to heal an injury. Something similar happens in axolotls, which are masters at limb regeneration. Heart injuries ...

Chromosome-level assembly of 14 snakes in a study led by the Chinese Academy of Sciences, China, has created a high-resolution genomic reference for the study of snake evolution. In a paper, "Large-scale snake genome analyses ...
Humans split away from our closest animal relatives, chimpanzees, and formed our own branch on the evolutionary tree about seven million years ago. In the time since—brief, from an evolutionary perspective—our ancestors ...
