We often hear about bacteria, but what exactly are they? A bacterium is a living organism that consists of a single cell (unicellular). It has ...

High-resolution imaging shows how MraZ breaks and deforms to attach to repeated DNA sequences, activating the gene cluster ...

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 ...

Researchers have discovered and characterized at the atomic level a mechanism that enables bacterial pathogens—including ...

A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail the ...

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...
