Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study -- conducted using E. coli ...

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 ...

ITHACA, N.Y. - Cornell researchers have uncovered the structure of a regulatory mechanism unique to bacteria, opening the door for designing new antibiotics targeted to pathogens. As the threat of ...

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, ...

Biofilms are conglomerates of bacteria and other organisms, which are feared in medicine as well as other areas because they can contain pathogens and are highly resistant to treatment. Chemists at ...

Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made 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 ...

Antibiotics revolutionized health care when they were introduced in the early twentieth century, making many severe and often ...

A Franco-British team of scientists has explored two human proteins recently identified as immune enzymes. Structural studies ...
