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 ...

Physicians have relied on a class of antibiotics called polymyxins to fight potentially life-threatening Gram-negative bacterial infections for more than 80 years. These drugs are typically reserved ...

Postbiotics are beneficial compounds produced when gut bacteria, including probiotics, break down prebiotics. In other words, ...

Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists ...

Probiotics interact with gut cells. This results in higher levels of specific proteins, known as anti-inflammatory cytokines. The presence of these cytokines brings in more macrophages and mononuclear ...

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 ...

There are millions of bacteria living in our guts. There are millions of dead bacteria there too. And scientists are learning just how much potential the dead ones have to improve our health ...
