And thanks to all poster presenters, including Moisès Bernabeu whose poster was in the top 5 of best posters at #ESEB2025. Congrats!

Then @kassipan.bsky.social from Wageningen University showed her PhD work to expand the genome diversity in the PVC superphylum, finding multiple phylum-level lineages and opening a door to investigating the cool cellular features in this phylum.

Way to go, Kassi! #ProudSupervisor

Great to see so many people at our symposium om the origin of eukaryotes. Thanks to all the speakers! #ESEB25 @julianvosseberg.bsky.social

Happy to share this one. We investigated the #phylogenetic placement and #genome_evolution of Pangui/Njordarchaea-unique #Asgardarchaea that might have undergone genome reduction...

🧵 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.

Our updated analysis suggests instead... www.biorxiv.org/content/10.1...

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 :)

Binnenkort ook aan de WUR: bijltjesdag. Weer een ontzettend verdrietig gevolg van de onnodige bezuinigingen op hoger onderwijs en onderzoek van dit kabinet, gesteund door de destructieve oppositie van oa CDA, CU en SGP. Lekker gewerkt Eppo!

One week left to submit your abstract! @eseb2025.bsky.social

Today we @mib-wur.bsky.social are on strike against the budget cuts in higher education.

#ESEB2025 Exciting symposium alert: (S50) Unravelling the origin of eukaryotes. 🦑🌴 With speakers Purificación López-García and Mark Field. We are looking forward to your abstract submissions! eseb2025.com/list-of-symp... @julianvosseberg.bsky.social

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...

Asgardarchaea & Alphaproteobacteria: key players for the assembly eukaryotic central carbon metabolism! Our new study reveals their gene contributions to glycolysis & TCA cycle, supporting synthrophic scenarios of eukaryogenesis.

Hey 🦋 people and especially archaea friends,
I made a starter pack with the current team of the Ettema lab by @ettema.bsky.social
on this platform :)
go.bsky.app/MzZPftE

Together with @ettema.bsky.social, @jvhooff.bsky.social, @stephkoe.bsky.social, Kassiani Panagiotou and @danieltamarit.bsky.social

Many novel Asgard genomes, cultivated Lokiarchaeia, new phylogenetic analyses: what insights do these and other recent studies provide into the enigmatic origin of eukaryotes? In this review in Nature, we discuss the latest findings and open questions: www.nature.com/articles/s41...
