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 ...

Type VI secretion systems (T6SS) are sophisticated nanomachines that bacteria employ to inject effector proteins directly into neighbouring cells. These systems are structurally reminiscent of ...

Bacterial cells can “remember” brief, temporary changes to their bodies and immediate surroundings, a new Northwestern University and University of Texas-Southwestern study has found. And, although ...

Darwin's theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce. Because of this, death is often seen as a failure rather than a ...
