Our bodies are a constant battlefield between pathogens and our immune system. But beyond this battle, there’s a larger war being fought between humans and drug-resistant bacteria. When antibiotics ...

Bacteria and the viruses that infect them are perpetually at war. Their deadly clashes push both kinds of microbes to evolve ...

Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the ...

It's an oft-cited strange-but-true fact: There are as many bacteria in your gut as there are other cells in your body. This community of microbes (not just bacteria, but viruses, fungi, archaea, and ...

Earth's bacteria are evolving to survive in space. Several strains sourced from the International Space Station (ISS) differed from the same strains on Earth, having qualities specifically adapted to ...

Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. Named after the Chinese military strategist Kongming—who ...

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found ...

Scientists may soon turn to bacteria originally found in feces to help cure chronic wounds more quickly. An open wound, for example, is a perfect little breeding pool for bacteria. But not all ...

Among the more than 500 species of bacteria that thrive in the human mouth, one seems to play by its own rules. This video shows one Corynebacterium matruchotii bacterium dividing into many daughter ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...

Bacteria have been around for billions of years. Could they have come up with complex behaviors that we just don’t understand yet? Could they have their own language? Their own culture? Their own ...
