I like to show the evolution of this classification to the students to highlight the fantastic bioinformatics work of Kira and Eugene and co-authors but also to illustrate the rapid development in the field ☺️.

True!
Scientists feel that the pressure to publish is rising, but that the time and resources they have to do the necessary research are falling, according to a survey of 3,200 researchers

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

You can get MSAs directly from AlphaFold DB now (alphafold.ebi.ac.uk). I also missed the FoldSeek implementation, which lets you search for structurally similar proteins direktly.
This saves some clicking around. Neat!

Our story describing the Panoptes bacterial immune defense system is now finally peer-reviewed and published today! www.nature.com/articles/s41...
The Panoptes system uses decoy cyclic nucleotides to defend against phage - Nature
The Panoptes antiphage system defends bacteria by detecting phage-encoded counter-defences that sequester cyclic nucleotide signals, triggering membrane disruption and highlighting a broader strategy of sensing immune evasion through second-messenger surveillance.

Uncovering the prevalence, key biogenesis enzymes, and biological significance of archaeal lipoproteins - Nature Communications
Lipoproteins are major cell-surface components in archaea, but their functions and the lipidation mechanisms are unclear. Here, Hong et al. identify two proteins required for attachment of proteins to unique archaeal membrane lipids via thioether bonds, and demonstrate their importance in archaeal physiology.
