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

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

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...

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 ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...
