How can you tackle emerging questions in cellular organisation, adaptation, and robustness? Let's find out together! This is your reminder to register for the EMBO | EMBL Symposium 'Cellular mechanisms driven by phase separation'! 🧬🦠 The meeting will bring together scientists from cell biology, biophysics, biochemistry, molecular biology, structural biology, developmental biology, polymer physics, and soft matter physics to study condensates in biology and disease. #EESPhaseSeparation Whether you are returning or new to the community, we hope you can join us next year! 📅 19 – 22 May 2026 📍 Heidelberg and Virtual 👉 Submit your abstract by 10 Feb 2026: s.embl.org/ees26-08-x

RNA bridges between charged regions on chromosome surfaces drive long-range attraction and clustering, revealing a condensate-like mechanism tunable by charge patterns. Read more: go.aps.org/3UU6wdv

🎉 Big congrats to @v_sorichetti and @SaricLab! Their simulations reveal how Ki-67’s charge distribution drives chromosomes to cluster together. Grateful to have contributed from @EMBL, with a special shout-out to our alumni PhD student @AHA_Alberto. 📖 journals.aps.org/prxlife/abstra…

Ki-67 shapes the nucleolus by anchoring chromatin via its amphiphilic properties biorxiv.org/content/10.110… #biorxiv_cellbio

For more detail, check out this great thread from one of the first authors @YH_YukiBio explaining the findings:

Ever wondered why nucleoli often have such complex shapes—despite behaving like liquids? If liquids tend to form spheres, why don’t nucleoli? What shapes them? We explore this in our latest preprint @embl. Great work led by Daja Schichler & @YH_YukiBio! biorxiv.org/content/10.110…

Interested in rapid imaging-based screening or sorting of rare cell populations? A new era of cell sorting has begun! Check out our latest review in @TrendCellBio on novel flow cytometers with imaging capabilities. Congrats, @terrabyte21! cell.com/trends/cell-bi…

EMBL Heidelberg researchers found how chromosomes switch from repelling each other to becoming sticky during cell division. They saw that protein Ki-67 turn chromosomes’ surface into a liquid-like glue that helps in the formation of daughter nuclei. 🔛 embl.org/news/science-t…

Extremely happy to see our story out in @MolecularCell! doi.org/10.1016/j.molc… We show how Ki-67 & pre-rRNA phase separate, gluing mitotic #chromosomes together! 🧼🧬🧲 @EMBL @EMBLHeidelberg @UniHeidelberg @ISTAustria @CuylenLab @SaricLab @EllenbergLab

Our latest paper is out today @MolecularCell! Led by a @AHA_Alberto and with important contributions from @SaricLab & @EllenbergLab! We show how chromosomes shift from being repulsive to becoming attractive during mitosis. Read all about it here: cell.com/molecular-cell…

@ralf_e_jansen @AHA_Alberto @embl @SaricLab @EllenbergLab Thanks! It has been shown that pre-RNAs are bound by Ki-67. We do not yet know whether other RNAs also bind to Ki-67.

Our new preprint describing how Ki-67 switches from a chromosome surfactant to a chromosome glue is online! Fantastic work lead by @AHA_Alberto @embl. Many thanks to our great collaborators from @SaricLab and @EllenbergLab. biorxiv.org/content/10.110…

@manuelalonsoya1 @AHA_Alberto @embl @SaricLab @EllenbergLab Thank you, Manuel!

@CuylenLab @AHA_Alberto @embl @SaricLab @EllenbergLab Looks Amazing Sara 🤗

I am extremely happy to share my @biorxivpreprint of my PhD work @EMBL! 🔬👨🏽‍🎓 A liquid-like coat mediates chromosome clustering during mitotic exit biorxiv.org/content/10.110…

The EIPOD-LinC postdoctoral programme is open for applications! Are you interested in self-designed interdisciplinary research on projects exploring life in context? Then take a look at our fellowship programme: embl.org/about/info/pos…

Excited to share our collaborative work with the Mahamid, Müller and @EllenbergLab! This has been a fantastic team effort @embl led by Herman Fung, @yukicosmos239 and @VeijoS.

Image-enabled cell sorting (ICS) – a next-generation cell sorting method – is helping EMBL researchers gain new insights into cellular function in health and disease, as well as to explore other innovative applications. embl.org/news/science/t…
