One of the most abundant living organisms on Earth may also be one of the most vulnerable. A group of ocean bacteria known as ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

In tight spaces that trap most microbes, one bacterium keeps moving by reconfiguring how it swims, revealing a new biological ...

A new study finds that a trait helping a marine bacterium survive and flourish today may ultimately become its Achilles Heel as ocean conditions continue to shift.

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Immune cells that eat bacteria in the body don’t stash them in specialized compartments as once thought, but turn them into critical nutrients that build proteins, create energy and keep the cells ...

It's estimated that 90 percent of the biomass in the oceans is made up of marine microorganisms, a group that includes protists, bacteria, archaea, fungi, and viruses. Microbes lives in some of the ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.
