How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller? Excited to share our latest work in @science.org on a new small polymerase. 1/n

Anybody know what the threshold was for MSCA funding this time round? Results are coming out and it looks brutal.

Very happy to say that our work on how axonemes are generated is now available on bioRxiv: www.biorxiv.org/content/10.6... - if you’ve ever wondered how the incredibly beautiful, complex structures within motile #cilia are constructed then this is for you!

New preprint from the lab 🎉: γ-tubulin is a novel target of the tubulin autoregulation pathway! Previously thought to exclusively target α- and β-tubulin mRNAs, we show that the TTC5–SCAPER–CNOT11 axis also degrades γ-tubulin mRNA, expanding the scope of this fundamental regulatory mechanism.

Excited to share Alison's @alisonkickuth.bsky.social paper from the lab out in @nature.com this week! We uncovered how a mechanical ratchet mechanism drives cytokinesis in early #zebrafish embryos.

🥳 Our new paper on C2CD3 is out in @plosbiology.org With the labs of @cellarchlab.com , @chgenoud.bsky.social , and @stearnslab.bsky.social , we revealed the mammalian centriole Distal Ring architecture by combining #UExM and in situ #CryoET. Big congrats to @ebertiaux.bsky.social and all involved.

Congrats to Michal Wieczorek (wieczorekgroup.ethz.ch/research.html, IMBB) on being selected as an @embo.org Young Investigator. The 2024 cohort highlights excellence across the life sciences, and this recognition reflects Michal’s outstanding scientific contributions.

Mike has been selected as EMBO YIP! Huge congrats to Mike and his team! 🥳 @mike-wieczorek.bsky.social

Thank you @embo.org for the honour of joining the EMBO YIP community! This would not have been possible without the efforts of our talented team at ETH Zurich and all our colleagues

The centriole is crucial for cilia formation, but its molecular architecture is not known. Research from the @Wieczorek Group at ETH Zurich reports structures of the centriole’s A-C linker, revealing how it crosslinks neighboring microtubule triplets. More: biol.ethz.ch/en/news-and-...

Thrilled to share that the final piece of my PhD work is now on bioRxiv! biorxiv.org/content/10.1... With support from @nvidia and the @NSF, we used AlphaFold to screen 1.6M+ protein pairs, revealing thousands of potential novel PPIs. All data can be viewed at predictomes.org/hp

957 proposals were submitted in the latest round of ERC Synergy applications. They expect to fund 50 which means around 5% success rate. This is really not sustainable and a lot of people are likely avoiding doing this knowing how poor the chances are. erc.europa.eu/news-events/...

Our latest collaborative effort - with Eva Gluenz and @zephyris-science.bsky.social - to understand how the various proteins and complexes of the axoneme contribute to ciliary motility:

Nature Communications will publish ~10K papers in 2025 pubmed.ncbi.nlm.nih.gov?term=%22Natu... That's ~$70M in revenue, while many of the non-profit journals that used to occupy that slot in the journal hierarchy have seen a precipitous decline in submissions in the 15 years it's existed.

I’m sure this guy is great, not the point, but to think the solution to Canadian scoence is to attract a few dozen scientists from abroad is complete nonsense. There are just as good scientists here. The problem is chronic underfunding. But this does not make headlines www.ctvnews.ca/health/artic...

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

Incredible story - congratulations @klanglab.bsky.social‬ !

Today, @rcsbpdb.bsky.social introduces Q-score in EM validation reports. Q-score assesses model-map fit. A new percentile slider will compare an entry’s average Q-score to the full archive and a resolution-matched subset. This would help judge whether the fit is typical for the reported resolution.

Huge congratulations to Girish and team on this beautiful study!
