Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria ...

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 ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

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

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...

University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein that can both sense and counteract viral infections. In the study, published ...
