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 ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...

MMS has long been promoted as a miracle cure, but new research shows it’s essentially a toxic disinfectant. While it can kill bacteria, it only works at levels that also damage human cells and ...

Antibiotic treatments are losing effectiveness against a range of common bacterial pathogens, including E. coli, K.

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses.

Although we often conceive of microorganisms — germs — as bad, the vast majority of them are not.

A petri dish full of dead bacteria isn’t usually cause for celebration. But for Stanford’s Brian Hie it was a game-changer in his efforts to create synthetic life. The perpetrator was a type of virus ...

Researchers at the Francis Crick Institute and AlveoliX have developed the first human 'lung-on-chip' model using stem cells taken from only one person. These chips simulate breathing motions and lung ...
