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 ...

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 ...

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 ...
