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 ...

The human body may seem like a single, self-contained system, but it actually hosts trillions of microscopic organisms. These ...

Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s ...

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

Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and ...

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.

Scientists have engineered a common probiotic bacterium to act like a microscopic drug factory that hunts down tumors and ...

Scientists have solved how circadian clocks within cyanobacteria, tiny organisms also known as blue-green algae, are able to precisely control when different genes are turned on and off during the ...

Viruses may be quietly reshaping how the ocean locks away carbon. Deep in the world’s oceans, microscopic bacteria play an outsized role in regulating Earth’s climate. These marine microbes help ...
