Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social. www.sciencedirect.com/science/arti... Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.

See this? This = implanting mouse embryo. Usually this happens inside its mother and is invisible to us, but we can actually watch implantation ex vivo with the hope of understanding why implantation goes awry in embryos of older women. A 🧵...

So grateful for an amazing experience at BioMatter: From Cytoskeleton to Embryo, Arolla 2025. I loved sharing my work during my talk, was honored to receive the Best Poster Award, and had so many inspiring conversations with brilliant scientists. An unforgettable week in a truly beautiful place!

✨We are looking for a PhD student interested in physical cell bio, imaging 🔬, biochemistry, #Xenopus 🐸 & #microtubules ✨ Join us @mpiib-berlin.mpg.de!

With great sadness and deep regret, we have to inform you that our department director and highly esteemed colleague Philippe Bastiaens @maxplanck.de passed away suddenly and unexpectedly on 15th of May.

Very happy to share the peer-reviewed version of our paper in which we study the formation and function of pair-wise and multi-way enhancer-promoter interactions in gene regulation (see thread below): www.nature.com/articles/s41...

June will be kicked off by Silvia Caballero from @imev-mer.fr on Thursday, June 5 at 2.15 pm (CET) (hosted by @plenart.bsky.social).

Intriguing findings from our Sendai collaborators Ruka Kitsui and Ryusaku Deguchi. While C. hemispherica spawns at dawn, Clytia IZ-D species spawns at dusk. This is not triggered by dark but, unexpectedly, by light-mediated extension of an autonomously-running 20h cycle. doi.org/10.1101/2025...

With a heavy heart I have decided not to attend a meeting in the US this June. I can’t act as if things are normal when science, universities, dissent & truth are all under threat. And I feel I can’t attend when there are scientists who are not able to travel to the US without fear of arrest.

It's a sun star, Heliaster helianthus apparently

Starfish!

We’re excited to share our work where we investigated the mechanisms of chromosome motion by tracking all #chromosomes, mapping their interactions, and live cell karyotyping, using #AI based denoising, segmentation and registration, published in Nature Cell Biology. www.nature.com/articles/s41...

Getting tissue stress from images is tough, and elastic tension sensors are a way to solve this. Still, the analysis is complex. Try our GUI gitlab.gwdg.de/betzlab_publ... implementing analytical solutions to obtain surface stresses AND shape parameters of beads and nuclei.

You are a biologist and want to get an idea why looking at intracellular active mechanics is important for cellular function? Check out our recent review preprint: arxiv.org/abs/2501.14538. We try to give an intuitive access, but also provide details in extensive toolboxes.

Great work! Congratulations!⭐️🐟

Our new findings on how chromosomes get ready for cell division are now published in @cellpress.bsky.social! Congratulations, Kai, @andibrunner.bsky.social and everyone else involved! 🤩 www.sciencedirect.com/science/arti...

I was invited, for July, to a scienctific meeting in Telluride (Colorado). I was told it is a wonderful place for a conference, and I was very much looking forward to an exciting meeting in a fantastic environment. I have just canceled my participation, despite having booked already everything.

🚀 Registration is officially OPEN! 🚀 Join us for the 3rd DivIDE Conference from 22–25 September 2025 in sunny Barcelona ☀️. An inspiring line-up of speakers awaits — reserve your spot and help spread the word! Follow the link for early bird registration: forms.creacongresos.com/DivIDE/

How exactly does #PLK1 function in prophase? Peter Lenart @plenart.bsky.social and coworkers find its inhibition to delay #CDK1 activation and mitotic entry, inducing a prolonged and phenotypically variable prophase-like state www.embopress.org/doi/full/10....

Hello Bluesky! We have a new paper out in EMBO Journal! We normally work on meiosis of oocytes, but this time we wanted to understand a fundamental mechanism of cell cycle control in cultured mammalian cells. The role of polo-like kinase 1 (Plk1) at mitotic entry remained somewhat controversial...

The German Research Council (DFG) has just announced drastic funding cuts—a deeply concerning development in times of growing hostility toward science and global crises. The DFG is not to blame; rather, it is the result of Germany’s self-destructive austerity policies. www.dfg.de/de/aktuelles...

After a long journey, Segment Anything for Microscopy is now published in Nature Methods! We significantly improve SAM for interactive and automatic segmentation in light and electron microscopy and build a user-friendly tool. www.nature.com/articles/s41...

Very excited that the lab's first paper is out! We showed that in stem cells, Aurora B controls abscission dynamics by regulating microtubules stability and MCAK recruitment. Very happy with this streamlined version of our 2024 preprint. www.cell.com/cell-reports...

Congratulations to @andibrunner.bsky.social and the team, and many thanks to the lab of Jan-Michael Peters for support! We found that the interphase and mitotic chromatin loop organization have more in common than previously thought: In both stages big loops are built first, small ones second

Our lab has multiple open positions for post-docs to study the regulation and function of cytoplasm mechanics during embryo development. Details below 👇👇 Please Repost !!! @ijmonod.bsky.social @cnrs.bsky.social

Mahamid and Woodruff labs use cryo-ET to look at mitotic centrosomes: Stunned to see the pericentriolar matrix taking shape, and what seem to be ‚S size’ gamma-tubulin complex oligomers capping the end of 11-pf microtubules. www.cell.com/developmenta...
