Come join our group in the beautiful (currently very snowy) Wageningen!

A newly discovered archaeal cell has a tiny genome and can’t metabolize biomolecules. It’s upending biologists’ definition of a living thing. “These types of organisms have been found before, but not as extreme as this,” said microbiologist Thijs Ettema.

Huge honor to receive this price! Glad to see the lichen research rewarded with such a distinction Thanks @pierremarcdelaux.bsky.social and @kellerjeanphd.bsky.social for your SUPERvision ✨ Merci @academiesciences.bsky.social pour cette opportunité et cette belle cérémonie!

📢Postdoc position available!🧪🧫🧬 Our group is seeking a motivated researcher to investigate the molecular mechanisms driving host–endosymbiont interactions. Full details & application: karriere.hhu.de//index.php?a.... Please help us get the word out!

So excited to see our review on how to detect horizontal gene transfers and their impact on plant functional evolution finally published in @theplantcell.bsky.social! Great teamwork between @lrsv-toulouse.bsky.social and LGDP-Perpignan 😎🥳🌱 academic.oup.com/plcell/advan...

New paper is out! We have studied the cute tiny Discocelia plataet sp. n. to obtain the first molecular data of the order Discocelida and clarify its cell structure. All this for a better understanding of the evolution of Cercozoa. onlinelibrary.wiley.com/doi/epdf/10....

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

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...

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

String manipulation is a critical daily task for bioinformaticians. Here is a cheatsheet using stringr: rstudio.github.io/cheatsheets... I probably use stringr::str_replace() once every other day... to clean up metadata (of course!) #rstats

AlphaFold is great, but contrary to public opinion it has not completely solved the protein folding problem. Much work remains to be done. clauswilke.substack.com/p/no-alphafo...

New vacancy in my team! PhD student position on microbial genome evolution, focusing on the evolutionary principles underlying bacterial genome architecture. Please repost and share with talented MSc students in #evobio, bioinformatics or related :) www.uu.nl/en/organisat... #MEvoSky #MicroSky

A fantastic resource for fern biology @natplants.nature.com 🔽! www.nature.com/articles/s41... Taking about ferns, are you interested by their immune system? Have a look at our recent preprint by @baptistebio.bsky.social @jacquet-chris.bsky.social 🔽 www.biorxiv.org/content/10.1...

Out today: Exciting intermediate between endosymbiont and organelle identified! Endosymbionts in Angomonas deanei lost nearly all bacterial cell division genes. Instead, we identified a host-encoded protein, ETP9, that became specialized for endosymbiont division. 1/2 www.science.org/doi/10.1126/...

🔗 Preprint alert: www.biorxiv.org/content/10.1... 🧵 New insights into plant immunity: using ferns to understand evolution! 🌱✨🌿 Excited to share my first (but not last) published research at @lrsv-toulouse.bsky.social. A THREAD … [1/9]

Excited to share our recent work on the evolution of ectomycorrhizal plants! 🌳 🧬 🖥️ doi.org/10.1111/nph.70054 With: Yvet Boele, @puginiercamille.bsky.social, @mbianc.bsky.social, Cyril Libourel, @maximebonhomme.bsky.social, @kellerjeanphd.bsky.social, @pierremarcdelaux.bsky.social A thread: (1/5)

Exciting news! I'm looking for a computational biologist to join my lab at Wageningen University & Research! It's a 3-year postdoc position on Holomycota genome architecture and evolution. Spread the word! www.wur.nl/en/vacancy/p...
