I invite you to check our paper entitled “Rebuilding Ukraine’s capacity for fundamental research in evolutionary biology” doi.org/10.1038/s415... in @natecoevo.nature.com about the Ukrainian School in Evolutionary Biology #USEB we organized in 2025.

The organizing committee: Natalia Volkova, Vladyslav Mirutenko, Walter Wolfsberger, Yaroslava Hasynets, Tetiana Barannik, Serhii Sydorovskyi, Yurii Gamulya, Taras Oleksyk, and Svitlana Serga would like to express gratitude to all lecturers & @eseb.bsky.social

The school was co-organized by Uzhhorod National University and V. N. Karazin Kharkiv National University, with support from NIOZ, Oakland University @cbgpmontpellier.bsky.social , and @inrae-france.bsky.social

We reflect on how to address problems that war brings to students and scientists. We hope that #USEB will promote international collaboration and knowledge exchange. Stay tuned for the announcement about the next #USEB 2027!

It has been two weeks since the unexpected death of Peer Bork, and all of us in his research group are deeply missing him. His scientific vision brought us together as a team, and we are immensely grateful for the time we spent together. 🧵

The main story are estimates of 'discoverable' species, genera, ..., phyla (?) in unbinned metagenomic contigs that do are not captured by MAGs. How many lineages lurk in existing data, and which habitats are prime hotspots for the discovery of novel diversity?

We've updated our recent @biorxivpreprint.bsky.social on 'Hidden but discoverable diversity in the global microbiome', led by @vishnuprasoodanan.bsky.social & @omaistrenko.bsky.social

We're up to 1000 studies in metalog.embl.de ! For the past year the focus was on finding inconsistencies in the data and creating the website, but now I have more time to go through the backlog of annotated issues to do QC and load them into the database.

Metalog: curated and harmonised contextual data for global metagenomics samples Abstract. Metagenomic sequencing enables the in-depth study of microbes and their functions in humans, animals, and the environment. While sequencing data

Great to see this finally published!

Phenotypic divergence among European populations was assayed in 173 isofemale lines, spearheaded by Esra Durmaz Mitchell and Thomas Flatt, we show that populations differed markedly in multivariate trait structure @evolletters.bsky.social @eseb.bsky.social academic.oup.com/evlett/artic... (5/7)

Phylogenomic Analyses Reveal that Panguiarchaeum Is a Clade of Genome-Reduced Asgard Archaea Within the Njordarchaeia Abstract. The Asgard archaea are a diverse archaeal phylum important for our understanding of cellular evolution because they include the lineage that gave

Huang, @tweethinking.bsky.social, Sepang et al. use phylogenetic analyses to reveal that the Njordarchaeales and Panguiarchaeales constitute the new class Njordarchaeia within Asgard archaea.

⚡ Russian forces launched another attack against Ukraine. 270 drones and 10 missiles were deployed.

Administrative buildings of energy sector enterprises were damaged. No casualties were reported, according to local authorities.

I will be at the #ESEB2025 conference! Text me if interested to meet or catchup:)
My poster is on Thursday about one of my hobby-projects about evolvability. Poster number is P03.284.

We're very happy to release our new database Metalog metalog.embl.de ! It offers manually curated and harmonised contextual data for 110k metagenomics samples across the globe, incl. precomputed taxonomic profiles, for interactive browsing and for download 🧵 1/7

Our preprint on estimating how many more prokaryotic taxa can be discovered in the unbinned fraction of metagenomic samples.
We predict that there are 10 archaeal and 145 bacterial novel phyla across all habitats.

The team's first preprint is out!

Led by ‪
‪@vishnuprasoodanan.bsky.social‬‬ & @omaistrenko.bsky.social , we asked a question (almost) as old as microbiology: how many prokaryotic species exist on Earth? More specifically, how much diversity is "hiding" in existing metagenomic data?
