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 ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial ...

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 ...

PHILADELPHIA - By combining two techniques, an international team of scientists led by researchers at The Wistar Institute has derived the "quasi-atomic" structure of a common bacteriophage, a type of ...

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 ...

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

A Dartmouth College research team has reported that plasmids can force bacteria to form dense clusters in order to tolerate antibiotics which suggests a source of treatment failure that does not ...
