How Hydra animals regenerate their own heads

A new paper in Genome Biology and Evolution maps out for the first time how Hydra, which are a group of small aquatic animals, can regenerate their own heads by changing the way that their genes are regulated, known as epigenetics.

The evolution of axial patterning

Body axes are molecular coordinate systems along which regulatory genes are activated. These genes then activate the development of anatomical structures in correct locations in the embryo. Thus, the body ensures that we ...

Eat more to grow more arms… if you're a sea anemone

Your genetic code determines that you will grow two arms and two legs. The same fate is true for all mammals. Similarly, the number of fins a fish has and the number of legs and wings an insect has are embedded in their genetic ...
