Scientists just invented microscopic knives capable of stabbing and killing bacteria on contact. The germ theory of disease emerged over the last several centuries to explain the way microscopic ...

A study reveals how microscopic bacteria can physically alter your cells and wreak havoc.

Starving bacteria (cyan) use a microscopic harpoon—called the Type VI secretion system—to stab and kill neighboring cells (magenta). The prey burst, turning spherical and leaking nutrients, which the ...

Researchers have discovered how bacteria break through spaces barely larger than themselves, by wrapping their flagella around their bodies and moving forward. Using a microfluidic device that mimics ...

Hundreds of different species of microbes live, laugh, and love in your gut. In the future, one of these might serve a new function: microscopic in-house pharmacist. A new study published Feb. 18 in ...

Recently Andrew rang in asking which animal eats bacteria. Apart from humans who like to eat bacteria by the bucketload (such as in yoghurt and cheese), there are millions of animals out there who ...

A study reveals how microscopic bacteria can physically alter your cells and wreak havoc.

Scientists have discovered a gruesome microbial survival strategy: when food is scarce, some bacteria kill and consume their neighbors. The study, published in Science, was conducted by an ...

How can bacteria squeeze through spaces narrower than a human hair is thick? A research team in Japan led by Dr. Daisuke Nakane and Dr. Tetsuo Kan at the University of Electro-Communications, Dr.
