Archaea the hornets of the microbial world. Discuss. www.biorxiv.org/content/10.6... TLDR: Archaeon kills bacterium with secreted phospholipase. Pretty nifty way to kill bacteria if you are a microbe with a very different lipid make-up, I reckon. No need to worry about accidentally killing yourself.

A Bactericidal Phospholipase from Archaea

Archaea kill bacteria, at least on occasion. The molecular underpinnings of these lethal interactions are barely understood. Here, we describe cinquedea, an α/β hydrolase secreted by the halophilic ar...

Surprised to discover that Thermo Fisher appears to show a fake western blot for the validation of one of their p53 antibodies. I've added a diagram to show the very similar bands. This does not appear to be one of the "published figures" but their own internal data.

tl;dr: MissAlignment learns to score misalignment then wiggles your alignments around to reduce that misalignment -> no more misalignment = high res STA 🌟 Watching @martenchaillet.bsky.social chip away at this was a real privilege! I’m excited to see this out and what you all will do with it 🙃

We're super excited to share MissAlignment: a new ML-based approach to reference-free tilt series alignment, spearheaded by @martenchaillet.bsky.social. We think it's going to make your cryo-ET life a lot better. Preprint: www.biorxiv.org/content/10.6... Code: github.com/warpem/miss-... 🧶 Thread:
