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

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 ...

Are all bacterial cells in a group alike? It doesn't seem so. A population of bacterial cells may be heteroresistant, which is to say that some may be able to evade the effects of antibiotics, while ...

Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once ...

New CU Boulder research shows that bacteria harness physical laws to operate at the edge of chaos and use calcium to independently diversify and find a place to settle down Let’s talk about the ...

Marine animals, such as the extremely simple flatworm Trichoplax, are ideal model organisms for studying the early ...

Rivals or allies—how do bacteria and fungi interact in our bodies? Until now, bacteria on our mucous membranes were primarily ...
