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 ...

(Nanowerk Spotlight) Bacterial eye infections blind millions globally each year, and current antibiotics increasingly fail to stop them. When bacteria develop resistance to drugs, they can withstand ...

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 ...

That is one big bacterium! Researchers have discovered a bacterium visible to the naked eye, challenging prevailing notions about the size of bacteria, most of which only can be seen when using a ...

Learn how bacteria inside marine snow may dissolve shell minerals and influence how the ocean stores carbon.

The bacteria, shown here next to a dime, are close to the size of human eyelashes. (Tomas Tyml | The Regents of the University of California, LBNL) Bacteria typically live out their teeny-tiny lives ...

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 largest ...
