Beautiful work!!

This is really great news for the Dutch structural biology community, a much needed upgrade of the national EM infrastructure. Thank you Friedrich and the many others who put in a lot of work to make this a reality!

Very happy that NWO supports this major upgrade of our national EM infrastructure. It is great that this initiative got broad support all over NL, and it will EMPower fantastic science - looking forward to that! www.uu.nl/en/news/33-m...

I'm excited to share our work on the regulation of endomitosis in worm intestines: www.biorxiv.org/content/10.1... We find that cells are able to uncouple nuclear division from cell division by transcriptional repression of key cytokinesis regulators

John Gurdon, former Group Leader and Head of @cellbiol-mrclmb.bsky.social has died. Despite calling himself a "total non-intellectual” his work to reprogramme somatic cells to pluripotent stem cells transformed the field of developmental biology.

Save the date! The second Hubrecht Symposium will take place on March 26, 2026. This year’s theme is “Molecular Machines in Development”, with Petra Hajkova, Andrea Pauli and @danielgerlich.bsky.social as keynote speakers. Registration opens soon, stay tuned via hubrecht.eu/hubrecht-symposium/. ‬

⚠️ Paper alert: Using a novel CRISPR screening approach, we mapped the entire regulatory network controlling Xist—key for X-chromosome inactivation. 👉 We discover how sex and development signals are decoded at a single gene locus. www.nature.com/articles/s41... 👇 Bluetorial

Today I am so pleased to present our work on how chromatin remodelers affect mesoscale chromatin organization. www.science.org/doi/10.1126/...

Teamwork at its best!! Thank you Vijay, for sharing your technologies and computational talent, for the fun discussions and work together, at random hours of the day or night 😃

(2) we observe intrinsic asymmetry in single-molecule fiber structures assembled on lagging and leading strands. This is neither resolved by CAF-1/ASF1, nor addition of active ISWI remodeler (Isw1a). Will be exciting to identify the factors that restore symmetry in reconstituted setting!(6/n)

Some (+)ve news to lighten another heavy weekend: our latest preprint (c/o Mattiroli + Ramani labs) is up! www.biorxiv.org/content/10.1... A tour-de-force by 1st authors Bruna Eckhardt & @palindromephd.bsky.social, focusing on chromatin replication. RTs welcome; tweetorial in 3,2...(1/n)

The latest work from ours and @vram142.bsky.social lab is out! True teamwork to visualize nascent chromatin with strand resolution, using a fully reconstituted system. Very proud of superstar-PhD student Bruna, and @palindromephd.bsky.social. Learning so much from Vijay’s amazing technologies! RT

Do not miss this opportunity!! Incredible science and mentor!

Check this out from our colleagues! Congratulations!

We thank Diego Dibitetto and @polosophie.bsky.social for sharing their research with the GIIN community today! Our next seminar will take place on Tuesday, October 7th featuring @fmattiroli.bsky.social and Marco Tigano. Subscribe here to join our mailing list: docs.google.com/forms/d/e/1F...

Preprint alert! We combined microfluidics, proteomics, and RNA-seq to map spatiotemporal protein expression during mouse somitogenesis and found a novel regulatory strategy: dynamic antagonistic gradients fine-tune signalling strength. doi.org/10.1101/2025...

Together with colleagues at the Dept. of Microsystems Engineering, we are looking for a PhD student to develop methods for femtoliter-scale sample dispensing in cryoEM sample preparation. edu.nl/h436k If you like interdisciplinary research & fascinating physics at ultrasmall scales, please apply!

The @NYTimes has done a fantastic job on explaining what the Trump administration’s savage cuts to biomedical research mean: cures that won’t happen. Please share this widely. This is a catastrophe. www.nytimes.com/2025/08/24/o...

It is not always safe to repair DNA Damage. Sometimes, cells "just bypass it". During DNA replication, repair of lesions on DNA can be dangerous. Cells instead "tolerate" DNA damage and focus on finishing replication. Read our review and find out why and how: doi.org/10.1016/j.ti...

if i were a better person i would do a tweetorial on our recent paper - but, hey, read the paper. its right there, waiting for you. #Giantvirus #histones are cool! their #nucleosomes are cool. check it out.! thats the tweetorial. rdcu.be/exXBX

I am very excited to share the newest paper of the lab, a huge amount of work led by our talented PhD student Maxime Galloy, in close collaboration with Andréanne Blondeau, our dedicated research assistant for 10 years! 🙌 www.cell.com/molecular-ce...

New preprint with @gfudenberg.bsky.social We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding. This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇 www.biorxiv.org/content/10.1...

Happy to see this impressive work from Sarah, Abdel, Jos, and colleagues out! Congratulations!! and happy we could contribute a tiny bit. Changes in histone dynamics is a mechanism of drug (PARPi) resistance in tumors, and it may be exploited in therapy.

Happy to see this out, great work from Niels, combining kinetic analysis, cryoEM and an unexpected gain-of-function mutant, nice work from master students Jan and Nina, from Kaustav and from Alex for the kinetics ‪@oncodeinstitute.bsky.social‬, ‪@nkinl.bsky.social‬
