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 ...

Zinc sits at the heart of many bacterial enzymes, so one of our immune system's simplest defenses is to keep zinc out of reach. Calprotectin, a neutrophil protein abundant at infection sites, is ...

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 ...

For the first time researchers have deciphered the near-atomic structure of filaments, called 'pili', that extend from the surface of bacteria that cause traveler's diarrhea. Without pili, these ...

Tubeworms (Hydroides elegans) are tiny marine creatures with hard shells that cause a lot of trouble and economic loss for boat and ship owners. They stick to the bottoms of boats and form ...

San Diego State University (SDSU) researchers scraped tubeworms (Hydroides elegans) off the bottom of boats in the San Diego harbor and discovered that a beneficial bacterium that aids them in ...
