We are happy to share that our snR30 story is finally out in @natureportfolio.nature.com 🥳 We report the first structure of a H/ACA snoRNP acting in ribosome synthesis thereby providing a detailed structural and biochemical view of the snR30 snoRNP guiding local 18S rRNA subdomain folding. 👇👇👇

Final grad paper is officially out! Grateful for the incredible team and all the support along the way! www.nature.com/articles/s41...

Preprint alert! ✨ In this project that I co-led with @benadler.bsky.social, we show that a miniature CRISPR-Cas10-like enzyme, mCpol, uses a novel inverse signaling mechanism to prevent the spread of viruses that attempt immune evasion by depleting host cyclic nucleotides. Check it out:

Our paper out @Nature: CARD domains mediate anti-phage defense in bacterial gasdermin systems CARDs are essential for caspase recruitment during human inflammasome activation. We now find them in bacterial immune systems Congrats Tana Wein! Thank you Kranzusch lab! www.nature.com/articles/s41...

scary but fascinating - cells have a degradation pathway that hunts down C-terminal scars (amides!) on damaged proteins. just wow. chemical biology plus CRISPR at its best. big congrats to all authors! www.nature.com/articles/s41...

In addition to today's posted work by @cryoclem.bsky.social on Archaeal ribosomes we further expanded RAPPL (www.biorxiv.org/content/10.1...) on multiple other complexes that work with ribosomes, subunits or even off the ribosome. Soon more...

by now you probably know that #giantviruses have #histones, but some also have histone variants! Check out our latest preprint on an essential H2B-H2A histone variant in Melbournevirus - a fantastic collaboration with the Abergel Lab, spearheaded by Ale Villalta. www.biorxiv.org/content/10.1...

So without further ado, HERE is the preprint: www.biorxiv.org/content/10.1.... The answer is YES—water masses do structure microbial communities for both prokaryotes and eukaryotes. In fact, they seem to be the single most important factor structuring microbial communities in the pelagic ocean.

Very cool! As Harry already pointed out!

And it’s been a while since I dipped my toe into the questions of what ‘species’ might mean for bacteria, and how they relate to ecology. But still interests me! genomebiology.biomedcentral.com/articles/10....

We are down to 2.32A and 2.61A for these specific ribosome complexes using tandem purification using RAPPL and tagged protein enrichment. In this case it was and hour and 45 minutes prep and 20-50 ml bacterial culture. www.biorxiv.org/content/10.1...
