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 ...

Researchers have uncovered the structure of a regulatory mechanism unique to bacteria, opening the door for designing new antibiotics targeted to pathogens. Cornell researchers have uncovered the ...

Microbes play an important role in climate because they release carbon dioxide into the atmosphere when they eat. Bacteria and their main predators, protists, account for more than 40 times the ...

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 ...

Nature often inspires engineering. Cicada wings, for example, have long tantalized researchers with their water-repellent and antimicrobial properties, which would be useful to replicate in ...

Clusters of a toxic bacterial protein have a surprising structure, differing from similar clumps associated with Alzheimer’s and Parkinson’s in humans, scientists report in the Feb. 24 Science. These ...
