An Asgard archaeon from a modern analog of ancient microbial mats A novel Asgard archaeon, Nerearchaeum marumarumayae, is present in microbial mats in Shark Bay, Australia. Combining genomic and structural analyses, together with high-resolution electron cryotomography, Nobs et al. reveal that these archaea possess unique cellular features that reflect their ancestry as progenitors of the earliest eukaryotic cells.

Today I stole some reading from our youngest daughter (9yo)...and guess what??? #archaea were there!!!
See special issue from Science et Vie Junior on Microbes, with a lot of interesting articles (not only for Kids...)...(in French)

The phage nucleus synergizes with an anti-defense protein to resist bacterial immunity Morgan et al. show that a phage-encoded protein functions as an antitoxin to counter DarTG2-mediated phage defense. They further explore the interplay between this anti-defense protein, the phage nucleus replication compartment, which encloses chimallivirus genomes, and the DarTG2 phage defense system.

Figure 1 shows the conceptual workflow of the algorithm. It first loads the configuration file and the input data of one or multiple binned metagenomes, yet evaluates each bin individually. It then iteratively processes each candidate bin in the input, going through the refinement tasks, potentially multiple times. The refinement either stops when the last step or a preset stop task have been reached or an unrecoverable error has been encountered. The algorithm tasks can be configured individually.

🤯 Manual MAG refinement? Still doing it by hand??

We’ve been there... You could just leave those messy, ill-assigned contigs/scaffolds in your data for NCBI to pick up during your submission…

This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up.

Prediction of eukaryotic cellular complexity in Asgard archaea using structural modelling - Nature Microbiology A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

How eukaryote-like was the archaeal ancestor of eukaryotes? Sequence searches alone can't tell us — so we used protein structure prediction to look deeper. 🧬

#OnThisDay in 1938, American evolutionary biologist Lynn Margulis was born. Margulis is most known for developing and popularising the endosymbiotic theory, which explains how eukaryotic cells evolved organelles from simpler prokaryotic organisms that resided within another and became incorporated.
