Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...

We often hear about bacteria, but what exactly are they? A bacterium is a living organism that consists of a single cell (unicellular). It has ...

Researchers used cryo-electron microscopy to reveal the structure of bacteria's 'propellers' in near atomic detail. University of Virginia School of Medicine researchers and their collaborators have ...

Biofilms are conglomerates of bacteria and other organisms, which are feared in medicine as well as other areas because they can contain pathogens and are highly resistant to treatment. Chemists at ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

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 ...
