We have an open position for a bioinformatics/theoretical microbial ecology PhD student to study viral strategies in the global Microverse! Join us at the @microverse.bsky.social at @uni-jena.de, please apply through this link: jobs.uni-jena.de/jobposting/9...

I have a postdoc position in metagenomic exploration available in my group. Candidates with documented experience in phylo & metagenomics and preferably with petabase-scale data mining and GLM workflows are encouraged to apply. Come join us! 🧬🦠💻 Please repost Apply here: www.wur.nl/en/vacancy/p...

Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious? Either way, we have good news. We’re delighted to announce the 2026 EMBO Workshop on Archaea, 6–10 July. Sign up: meetings.embo.org/event/26-arc... We look forward to seeing you in Cambridge, UK. Please repost!

Come join us! Soon I will be advertising a postdoc vacancy in my group as part of my @erc.europa.eu AdG project 'DARK ROOTS'. Focus of the project will be on phylo- and metagenomic mining of novel prokaryotic lineages. I will soon post a link here - stay tuned, and please repost! #asgardarchaea

#Archaea, #DPANN, #phylogenetic_reconciliation New preprint online! www.biorxiv.org/content/10.1...

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...

Doe. Het. Niet. Bezuinig niet op het onderwijs! 🟥 Vandaag maakt het CDA in de Eerste Kamer wéér dezelfde fout als eerder dit jaar door de bezuinigingen van de VVD aan een meerderheid te helpen.. Stem morgen op een partij die het onderwijs niet laat vallen! 🔴🟢

Nou nee, dat mag niet. Een school moet een veilige plek zijn voor álle leerlingen. Dat staat ook in de wet. Het afwijzen van homoseksuele relaties geeft de boodschap dat iemand niet zichzelf mag zijn. Dat mag niet én is ronduit schadelijk. nos.nl/nieuwsuur/co...

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 #ESEB2025

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

Interactive symbiosis in silico (back) and in vivo (front). #ESEB25

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

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...

#Asgard,#phylogeny 1/ 🧵 Does MAGs contamination affect the placement of Njord as suggested by Zhang et al, 2025? www.nature.com/articles/s41... 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 :) www.uu.nl/en/organisat... #MEvoSky #MicroSky

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! nos.nl/l/2567448

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. #StopTheCuts

#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. rdcu.be/eb0aK

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

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...
