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

Bacterial cells can 'remember' brief, temporary changes to their bodies and immediate surroundings, a new study has found. And, although these changes are not encoded in the cell's genetics, the cell ...

A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical ...

Common gut bacteria use protein delivery systems to interact directly with human cells, reshaping how scientists view the ...

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 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 ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings, published in the journal Nature Communications , describe ...

Humans have long had a love-hate relationship with bacteria. While there are bacterial strains that humans cannot live without, such as those that help us digest our food and bolster our immune ...
