Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like this one ...

Our bodies are home to trillions of microbes, including bacteria, viruses, fungi, and a whole host of others. Now, Stanford scientists have discovered an entirely new class of biological entities ...

Bacteria that cause intestinal infections typically avoid a stinky chemical—one that can kill them at high enough ...

For the first time, scientists have spotted rogue bits of RNA colonizing the bacteria in our gut. These “obelisks,” as the researchers have dubbed them, may represent a whole new class of ...

Scientists have identified a new type of protein in bacteria that could change our understanding of how these organisms ...

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers are showing how ...

Bacteria permeate virtually every corner of the Earth. Most bacteria live in a biofilm state to enhance their survival and propagation, and to perform essential tasks for many ecosystems. Aa Aa Aa ...

Bacteria typically live out their teeny-tiny lives in the microscopic realm, but now scientists have found a gargantuan one the size and shape of a human eyelash. The new find is "by far the ...

Researchers have examined the human oral microbiome and discovered tremendous variability in bacterial subpopulations living in certain areas of the mouth. In many cases, the team was able to ...

BUFFALO, N.Y. — In the quest to take the “forever” out of “forever chemicals,” bacteria might be our ally. Most remediation of per- and polyfluoroalkyl substances (PFAS) involves adsorbing and ...

Bacteria can slip into the brain by commandeering cells in the brain’s protective layers, a new study finds. The results hint at how a deadly infection called bacterial meningitis takes hold.

An international team of scientists has developed a new family of compounds that can clear bacterial infections in mice. Some of these infections can result in serious “flesh-eating” illnesses ...
