Never thought I’d do real E. coli research, so far I used if only for cloning & protist snacks in my MSc 😅 But here I am simulating chromosomes & shuffling motifs. Watching @loreoliv.bsky.social and the lab turn those predictions into real data was pure magic.✨ Grateful to be part of this team!

Folddisco finds similar (dis)continuous 3D motifs in large protein structure databases. Its efficient index enables fast uncharacterized active site annotation, protein conformational state analysis and PPI interface comparison. 1/9🧶🧬 📄 www.biorxiv.org/content/10.1... 🌐 search.foldseek.com/folddisco

📢 New preprint alert! We used comparative genomics on 72,000+ bacterial genomes to uncover the genetic basis of microbial adaptation to multicellular hosts—plants and animals alike. www.biorxiv.org/content/10.1...

Excited to share our work on WitChi! 🛠️🖥️ We tested it on the GTDB r220 archaeal supermatrix (5,869 taxa & 10,101 cols) removing 55% of sites in <2h. The phylogeny showed several interesting groupings with overall improved branch support: #phylogenetics #ArchaeaSky #MSA #opensource #MEvoSky #MicroSky

I'm happy to announce the latest release of the GlobDB, available at globdb.org. The GlobDB is a database of "species dereplicated" microbial genomes, and as of release 226 contains twice the number of species-representative genomes (306,260) than the latest GTDB release.

1. 🧵 New preprint out! WitChi: a fast, open-source Python tool to detect, quantify & prune compositional bias in MSAs. Lightweight, tree-free, scalable to 5k+ taxa... so we applied it to the GTDB archaea MSA. #ArchaeaSky #MEvoSky #MicroSky 🔗 doi.org/10.1101/2025... 💻 github.com/stephkoest/w...

Exciting new research! Matthias Horn & Lukas Helmlinger from #CeMESS uncover how chlamydiae thrive in social amoebae by skipping their extracellular stage. Read their groundbreaking study in Current Biology (@currentbiology.bsky.social): 🔗 cemess.univie.ac.at/news/detail-...

Excited to share our first paper on the symbiosis between chlamydiae and social amoebae showing in detail the adaptations of endosymbionts to the social life style of their host! 🎉

Asgard archaea have actin - but what about microtubules? Where do they come from? 🧐 Our new paper www.cell.com/cell/fulltex... by @xujwet.bsky.social & @florianwollweber.bsky.social, in collaboration with the Schleper & Wieczorek labs, describes tiny Asgard microtubules! #TeamTomo #ArchaeaSky 1/6

🚨 New paper alert! 🚨 A robustly rooted tree of eukaryotes sheds light on their deep evolutionary ancestry—suggesting that the Last Eukaryotic Common Ancestor (LECA) may have had an excavate-like cell architecture. 🧵🔬 (1/) www.nature.com/articles/s41...

Hi BlueSkyers! I'm an evolutionary biologist, microbiologist, entomologist, lover of nature, and long-time researcher on symbiosis. I'm realizing that BlueSky is useful and generally non-toxic so here I am (having quit Facebook in Jan 2017, and Twitter in Oct 2022).

(1/2) Preprint alert! In collaboration with @yifanzhou.bsky.social and @mkrupovic.bsky.social we describe host-parasite layers in hypersaline systems of the Danakil Depression. Haloarchaea host nanohaloarchea and both are infected by viruses (12 new families found). www.biorxiv.org/content/10.1...

Phylogenomic analyses reveal that Panguiarchaeum is a clade of genome-reduced Asgard archaea https://www.biorxiv.org/content/10.1101/2025.02.13.637844v1

And now our department can also be followed pn Bluesky!! Follow us!!

Congratulations to our very own John van der Oost!!!! #BeijerinckPrize

Are you interested in studying archaea with their diverse symbionts? We look forward hearing from you: workingat.nioz.nl/o/postdoc-po...

Make sure to tune into Archaea Power Hour in just a few short hours! Sign up to receive the Zoom link here: t.co/b17JFAaZQ6. Checkout out our exciting schedule below:

what a nice highlight of some excellent (archaea) researchers :)

Fun little Q&A! Thank you for the opportunity Current Biology @currentbiology.bsky.social www.cell.com/current-biol...

We have an open position PhD position in a project aiming to develop novel methodologies for phylogenomic reconstruction of plasmid evolution. See details and how to apply in the Ad. Candidates who will review the relevant literature (see Ad) have a higher chance to write a successful application.

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1... A little thread below 1/n

The contribution of natural transformation for the acquisition of novel genes has been notoriously difficult to quantify because it relies on recombination (which is affected by other processes). Here's a first estimate : doi.org/10.1101/2025... (for the very busy: 1-6% of gene gains) #MicroSky
