New preprint by @kartiksaiyer.bsky.social, @leodigel.bsky.social and others from @cemau.bsky.social about how cable bacteria grow using electrodes instead of oxygen: www.biorxiv.org/content/10.1...

Extracellular electron transfer in cable bacteria enables growth rates comparable to aerobic respiration

Cable bacteria are filamentous sulphide-oxidisers performing long-distance electron transfer in redox-stratified sediments by transporting electrons over centimetre-scale distances to reduce oxygen. H...

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

🚨 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.
