Nice new paper from Stas Shvartsman's group presenting an elegant mathematical model for the control of metamorphosis and testing it using Erk optogenetics. www.pnas.org/doi/10.1073/...

Happy to have contributed, together with former student Yitong Xu, to this paper. Read the thread below from @brugueslab.bsky.social for more details.

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. Read more in this thread 🧵 and at www.nature.com/articles/s41... 🤩 @poldresden.bsky.social @mpi-cbg.de

Congrats, Ale and lab. A big step forward with a lot of new and unexpected observations! These waves are fascinating indeed

Advanced grad students + postdocs: apply for the 2026 #kitpqbio summer course, "Physical Principles of Morphogenesis in Plants and Animals," at buff.ly/OXXMKEv. Apply by Feb. 1. Course directors Adrienne Roeder (Cornell) and Sebastian Streichan (UCSB)

@sushantbangru.bsky.social and @rdiegmiller.bsky.social new review on regeneration is out in Nature Reviews Molecular Cell Biology. A fun piece to write and another great collaboration with @kenposs.bsky.social.

We are hiring!

Just got back from a great visit to Vienna, spending time both at @impvienna.bsky.social and @istaresearch.bsky.social. Followed by a great visit to @embl.org. Amazing science, great and supportive colleagues and most notably incredible young trainees. It was so much fun to meet everyone.

Thanks, Paul! Means a lot coming from you, as your papers have been great inspiration for this study

🍽️🧬 How do diet and gut microbes shape fertility across generations? 🪱🔬 Our Laboratory at #InstitutPasteur is recruiting a PhD student to study epigenetic inheritance of fertility using C. elegans. Fully funded via the International PPU program. Apply now! 🌍 #PhDposition #Epigenetics #Inheritance

Tissue 'tectonic' collision is detrimental, but flies found two distinct solutions! Gratifying and grateful to be included in this collective effort, w/ Steffen Lemke, to crack the (or 'a') code of #cephalicfurrow, now out in @nature.com, all with @paveltomancak.bsky.social at the helm. (1/9)

Priyom's preprint is out on biorxiv. See below for a detailed thread. In a nutshell, she has discovered and characterized the oscillator that times notochord and spine segmentation in zebrafish. Turns out that there are uniform Erk oscillations across the entire tissue that act as timekeepers!

Building a spine is no joke, but thankfully zebrafish have their own clocks to keep the pace. Excited to share our preprint on the role of biological oscillators in coordinating notochord development! (www.biorxiv.org/content/10.1...) Additional thread below

Heartfelt obituary of Ben Shilo by Stas Shvartsman

Just noticed a super nice preview of our paper by @ditalialab.bsky.social and Alexandra Hiestand. As always, good editorial experience with @cp-cellsystems.bsky.social www.cell.com/cell-systems...

Great dinner with current and former members of the lab, as well as current and former Duke members and friends of the lab. Great to catch up with @ceriweber.bsky.social ,Ben, @woonyunghur.bsky.social and share stories. Great @socdevbio.bsky.social meeting!

Excited to see @drsusanna.bsky.social 's work out as a preprint. Please read the thread below for some more information or check the paper out on biorxiv. www.biorxiv.org/content/10.1...

A heartfelt thank you to @izfs.bsky.social for this incredible honor! I'm so grateful to receive an award in memory of Dr. Chi-Bin Chien, an inspiring scientist and pioneer in the zebrafish community 🐟💙

Very much looking forward to this meeting!

Highly recommended! A great lab and wonderful mentor.

Nice News & Views on our recent paper from Tim Saunders. www.nature.com/articles/s41...

We are hiring! Interested in X chromosome inactivation, cell biology, and epigenetics? Funded postdoctoral position in our lab at the Koç University Mol Bio and Genetics Department, in Istanbul Türkiye. DM for more details.

Our paper, led by @argo-mkhrji.bsky.social and @woonyunghur.bsky.social, on cortical migration of nuclei in drosophila embryos came out today in @naturephysics.bsky.social. Argo wrote a comprehensive thread below. A great collaboration with Massimo Vergassola and @streichan.bsky.social.

Great new paper on spatiotemporal organization of cell division in zebrafish embryos. The mitotic waves preceding the ZGA are phase waves set by differences in N/C ratio, driven by geometry-induced asymmetric divisions. Important new insights and very interesting addition to the field.

What an awesome paper from Olga showing how in zebrafish the scaling of anaphase movements is controlled by cytoplasmic flows! Love to see a new role for cytoplasmic flows ;) and excited to learn that scaling of anaphase is controlled so differently in fly and fish embryos.

Very nice dispatch describing Yitong's paper from Akihiro Tanaka and Yuta Shimamoto. www.cell.com/current-biol...

Ashley's postdoc work is now posted on bioRxiv. www.biorxiv.org/content/10.1...

📣 Excited to receive the 💥 NSF CAREER 💥 Award. Our group is looking for PhD students and postdocs interested in the Nonlinear Dynamics and the Physics of Living Systems, with support from NSF, HFSP, and other sources. We’d appreciate your help in spreading the word! @ucsdphysci.bsky.social

Join us next week for another western/evening 🌙 session seminar! Our speakers will be: Stefano Di Talia @ditalialab.bsky.social and Chaitanya Dingare 🗓️ Thursday, January 23rd at ⏰ 09:30 PST / 12:30 EST / 17:30 UTC / 17:30 GMT / 18:30 CET

How did microtubules adapt to support life across 🐸 species at divergent thermal niches? 
 Now online & OA @currentbiology.bsky.social Thanks to Ella, Luca, @biswashere.bsky.social & Carolyn @mpiib-berlin.mpg.de @BirkbeckUoL
 🙌 Enjoy reading! 👉 www.cell.com/current-biol...

Yitong's paper is now out in Current Biology. In this paper, we investigated what sets the speed of chromosome separation in anaphase and found that it is mainly set by the dynamics of the cell cycle oscillator. This was a fun collaboration with @brugueslab.bsky.social www.cell.com/current-biol...

So proud of lab alumna @vdeneke.bsky.social for her exciting discoveries on zebrafish fertilization.

Please spread the word! We are looking for postdoc(s) interested in quantitative problems in Development and Regeneration. Previous experience in quantitative biology is not required. We will support you and provide a great training environment if you are committed to learn new things.

This was such a fun meeting in a great location. Thanks Lendert and Julia for organizing
