Diversity, ecology, cell biology and evolution of the Asgard archaea Nature Reviews Microbiology, Published online: 05 March 2026; doi:10.1038/s41579-026-01288-wThe Asgard archaea have become a cornerstone of archaeal research, particularly for studies aiming to unravel the origin and early evolution of eukaryotes. This Review outlines the current state of the research field focusing on these intriguing microorganisms and discusses future research directions aiming to resolve their diversity, ecology, cell biology and evolution.

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

Huge news 🌍🧬
The Protist 10,000 Genomes Project is joining the Earth BioGenome Project.
Protists may represent the majority of eukaryotic diversity — yet only a tiny fraction have reference genomes.
Time to change that. 🚀✨

hey @joshuasweitz.bsky.social this paper rocks. empirical confirmation of an intuition that is currently load-bearing in a paper i've been scared to finish. i love it academic.oup.com/ismej/articl...

To add one thing: if you have the data to run both classic dN/dS tests and MK tests, choose the latter. dN/dS tests are blind to positive selection in the important, constrained proteome, while MK test will work regardless of constraint, if DFE well estimated.

Today we published a Correction on our 2023 @nature.com paper reporting the heimdallarchaeial ancestry of eukaryotes: www.nature.com/articles/s41...

Corrected paper: www.nature.com/articles/s41...

Importantly, the re-analyses of the corrected dataset are consistent with the original findings.

Normally a Cell paper with one's name as corr. author would be a reason to break out the champagne. But today I have rather mixed feelings, as I inherited that spot from Peer Bork upon his untimely death. Still, congrats to all the authors! May we finish all the projects that we started with Peer!

Phylogenetic tree of 8,943 bacterial genomes. The shaded branches in the tree represent different types of oxygen requirements, and the outermost ring indicates taxonomic lineages.

Using machine learning to sort over 80,000 bacterial genomes into aerobes and anaerobes, researchers find that oxygen-breathing bacteria likely evolved in local oxygen-rich environments 200–400 million years before the Great Oxidation Event. In PNAS: https://ow.ly/jZWQ50Y3LhU

An eye-popping discovery: early vertebrates had four eyes rather than two Eyes on a face’s front or side enable a brain to perceive images. Fossil evidence suggests that two light-sensitive organs on top of ancient vertebrate heads generated images, too.

🗜️⚡ If you use gzip/gunzip a lot in your pipelines, switch to the faster"libdeflate" versions instead! They use modern CPU capabilities to achieve a 2-3x speedup.

libdeflate is in conda, and "libdeflate-gzip" and "libdeflate-gunzip" are drop-in replacements. #unix
