Most bacteria, including many bacterial pathogens, are surrounded by an outer protective layer of sugar molecules, known as a ...

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 ...

A new function-based sequencing technique using optical tweezers and taking advantage of the properties of gravity is letting researchers analyze bacteria cells one by one. The study, conducted by ...

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

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 ...
