In remembrance of Peer Bork  | EMBL EMBL and its community are deeply saddened by the death of Peer Bork, the organisation’s Interim Director General.

very sad news. Peer Bork was one of the leaders of our field, a wonderful scientist, and he's much too young to be gone. www.embl.org/news/embl-an...

Yes, great work, I am so glad this is finally published! I hope it will be useful to many in the community.

Anthony A. Hyman will become EMBL’s next Director General.

He joins EMBL from @mpi-cbg.de in Dresden. He is also Professor of Molecular Biology @tudresden.bsky.social, and was a group leader at EMBL Heidelberg from 1993 to 1999.

How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social.

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!

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).
