Microbes like viruses and bacteria have adapted to live virtually everywhere, including inside the gastrointestinal tracts of many animals and humans. But how do these microorganisms propogate their ...

New studies from Arizona State University reveal surprising ways bacteria can move without their flagella—the slender, whip-like propellers that usually drive them forward. Movement lets bacteria form ...

While scientists have studied how bacteria move toward food using a chemical radar known as chemotaxis, they have only watched single species swim in isolated environments over distances of only a few ...

A cleaner goby cleans a grouper in a Caribbean coral reef. These little fish clean much bigger fish of parasites and bacteria. Where do you go when you’re a fish and you need a skincare treatment?

Bacteria can effectively travel even without their propeller-like flagella — by “swashing” across moist surfaces using chemical currents, or by gliding along a built-in molecular conveyor belt. New ...
