Every cell in an animal's body carries the same DNA. Yet that single genetic blueprint somehow produces neurons that fire, muscles that contract, and tissues with entirely different jobs. How ...

One of the biggest quests in biology is understanding how every cell in an animal’s body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...
