Blow up a long balloon and two things happen: it gets longer and it gets wider. Now imagine a living cell that inflates itself under enormous pressure and yet only grows longer, never adding width.

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...

An innovative imaging technique developed at Carnegie Mellon University reveals single bacterial cells leaving their biofilm community. Watching the bacteria in real-time at high resolution affords ...

Inside the gut of a caterpillar lives a worm, and inside the worm lurks a bioluminescent bacterium named Photorhabdus asymbiotica, which makes the caterpillar glow in the dark. But this ...
