Just realising again on my way to work: AI will never ever be able to bring the joy @eliza-coli.bsky.social images bring to me whenever I walk through my Institute's hallway. Thanks so much, Eliza!

Phage-induced lysis may only be the beginning of something else. Great effort by Antonio (first and corresponding author) showing the occurrence of extracellular DNA synthesis and structuring! www.biorxiv.org/content/10.6...

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth! #protistsonsky 🧵

We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

An Asgard archaeon with internal membrane compartments Brilliant study led by @fmacleod.bsky.social and Andriko von Kügelgen. Tight collaboration with @buzzbaum.bsky.social and lab. Congrats to all authors! www.biorxiv.org/content/10.1...

🚨 Imagine a bacterium that refuses to follow the textbook: It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks. Meet Litorilinea aerophila — and here’s why it blew our minds.
