Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Harvard immunologist Dennis Kasper and his colleagues have found that tiny changes in gut bacteria can flip the immune system from calm to inflamed, even when the microbes look harmless. Their work, ...

The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions ...

Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can ...

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

Scientists at LSU have patented a novel way to kill cancer cells using staph bacteria, sometimes called the “superbug.” ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

Pathogenic bacteria have evolved a variety of mechanisms to thrive within their hosts, even in the face of antibiotic treatment. One particularly effective strategy is the expression of membrane ...

Can bacteria that survive washing and disinfection in food production facilities spread antimicrobial resistance?
