Microbiome

To stay healthy, humans and some other animals rely on a complex community of bacteria in their guts. But research is starting to show that those partnerships might be more the exception than the rule.

New studies help to explain how microbes in the gut can shape a host’s fear responses.

In the “underground economy” for soil nutrients, fungi strike hard bargains and punish plants that won’t meet their price.

Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.

How does evolution select the fittest “individuals” when they are ecosystems made up of hosts and their microbiomes? Biologist debate the need to revise theories.

Maria-Luiza Pedrotti is illuminating the unseen worlds of plastic-eating bacteria that teem in massive ocean garbage patches.

The dizzying network of interactions within microbe communities can defy analysis. But a new approach simplifies the math and makes progress possible.

Kidneys sniff out signals from gut bacteria for cues to lower blood pressure after meals. Our understanding of how the symbiotic microbes affect health is becoming much more molecular.

The soil teems with billions of hidden microbes. Researchers have begun to catalog how these organisms are changing the world.
