Similar in function to ballast tanks in submarines or fish bladders, many water-based bacteria use gas vesicles to regulate their floatability. In a new publication in Cell, scientists from the ...

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

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 ...

University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein ...

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 ...

The microbiome—the trillions of bacteria, viruses, and fungi that live quietly in our body—plays a crucial role in shaping human health by providing a variety of micronutrients necessary for vital ...

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 ...

Our gut is home to countless bacteria, which help us to digest food. But what exactly do the microorganisms do inside the body? Which enzymes do they produce, and when? And how do the bacteria ...
