Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

The original version of this story appeared in Quanta Magazine. Prochlorococcus bacteria are so small that you’d have to line up around a thousand of them to match the thickness of a human thumbnail.

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By systematically identifying thousands of rapidly evolving ...

Enzymes known as kinases play a critical role in cell growth, metabolism and signaling in a multitude of organisms across the tree of life—from algae to helminths to mammals. Now, scientists have ...
