A new portable instrument could help to lure useful bugs in from the wild.

An experiment delves into how the microbiome shapes immunity.

Bacteria coordinate a pilus's movement based on touch.

Lymph from cattle proved more effective at inducing immunity to smallpox than the older, person-to-person method.

The MIT associate professor wants to understand microbial communities in their ecological context.

Molecules produced by resident bacteria and their hosts may signal immune cells to attack the body’s own tissues.

Quieting immune attacks against pathogens and even providing nutrients to the invaders could improve health, according to a new line of research.

Antigens originating from the microbiome may trigger an autoimmune response.

Kelp in warm, acidified waters develop blistered fronds—and the composition of microbial communities could help explain why, a study suggests.

Symbiotic bacteria, metabolism, and stress pathways can all help animals tolerate, rather than succumb, to disease.
