(1/5)For over a century, the hunt for new antibiotics has focused almost exclusively on bacteria and fungi. Today, that paradigm shifts. By coupling state-of-the-art AI with the vast, largely uncharted diversity of Archaea, we open a new frontier for molecular discovery.
Deep learning reveals antibiotics in the archaeal proteome - Nature Microbiology
Use of artificial intelligence to mine proteomes of archaea led to the discovery of archaeasins, antimicrobials that kill drug-resistant bacteria in laboratory and animal models, offering a promising ...

A chemical radar allows bacteria to detect and kill predators
Pseudomonas syringae can detect and kill microbial predators via a chemical radar (Cra), which also allows the bacterium to infect plants despite predation pressure.

Crazy stuff in PNAS

dental plaque bacterium 𝘊𝘰𝘳𝘺𝘯𝘦𝘣𝘢𝘤𝘵𝘦𝘳𝘪𝘶𝘮 𝘮𝘢𝘵𝘳𝘶𝘤𝘩𝘰𝘵𝘪𝘪 can divide into an unprecedented 14 daughter cells at once—then each daughter cell starts growing immediately in a rare process called multiple fission, achieving 0.5 mm per day of expansion
