Scientists produce chimp genetic map to combat trafficking

Scientists have produced the first genetic map of chimpanzees in the wild, offering a detailed reconstruction of the endangered species' past migrations, and a new tool to combat illegal trafficking.

When the equinox gene appears, repair transitions into regrowth

When animals experience a large injury, such as the loss of a limb, the body immediately begins a wound healing response that includes sealing the wound site and repairing local damage. In many animals, including humans, ...

A crowning achievement in understanding head development

Cranial neural crest cells, or CNCCs, contribute to many more body parts than their humble name suggests. These remarkable stem cells not only form most of the skull and facial skeleton in all vertebrates ranging from fish ...

Mechanical forces shape the 'immortal' hydra

Hydras are tiny creatures with regenerative superpowers: they can renew their stem cells and replace damaged body parts in only a few days. Now, researchers in the Tsiairis group have found that mechanical forces turn on ...
