Please allow me to introduce... our new preprint 🎉 Together with Michael Zhao, Anna Erzberger and Alexander Aulehla, we investigate pattern formation due to aggregation in confined systems. You can find it at arxiv.org/abs/2509.08533 @michaelzhao.bsky.social @erzbergerlab.bsky.social

Looking forward to it!!

Fresh from the press💥 We asked what happens when you evolve gene regulatory networks computationally at scale. Do general principles of GRN evolution jump out? Is the process predictable? Read on to find out @prxlife.bsky.social @crick.ac.uk @ucl-ipls.bsky.social 👉 journals.aps.org/prxlife/abst...

Drs. Borzo Gharibi, Silvia Santos, and a team at @crick.ac.uk generated an ESC-derived 3D model of the post-gastrulation #amnion. 📄 @cellpress.bsky.social - bit.ly/45bJs0c 🎤 bit.ly/4kE4eKf

🧵Why do early embryonic cell cycles speed up with temperature almost like simple chemical reactions, but not quite? 🌡️ Across frogs, fish, worms, and flies we found a shared scaling law, and uncovered why deviations from Arrhenius behavior emerge. 👉 doi.org/10.1038/s41467-025-62918-0

🧵Does the nucleus set the cell cycle clock? 🕒 In frog egg extract “mini-cells” we see that as nuclei grow, cycles slow down. The period scales with the nuclear-to-cytoplasmic ratio, across Xenopus species, and even when DNA replication or transcription are blocked. 👉 doi.org/10.1016/j.cu...

Many years in the making but now finally online! What determines the temperature scaling and thermal limits of cell cycle duration in embryos? We tackled the question using a combination of dynamical systems analysis and experimental measurements in embryos and in cycling Xenopus extracts.

BOOM💥Martina was on fire at the recent #Biologists100 meeting on Liverpool, sharing her research on cell cycle oscillations. #proudPI

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

Beautiful work from @santoslab.bsky.social A 3D model of human amnion from hESCs These recapitulate amniotic sac development, revealing GATA3 as key amniogenesis driver & autoregulatory BMP/Wnt feedback loops And check out the size of them in the video www.cell.com/cell/fulltex...

We can't believe #EESTCBio is over! 😱 Thank you to the organisers, speakers, and participants for creating such a vibrant space for critical thinking. It was a joy to see you exchange ideas, challenge assumptions, and explore new perspectives 💡 We hope to see you again at the next edition! 👋

I am recruiting an #ERC funded PostDoc to work on the evolution of vertebral counts in cichlids. This is an experimental project & will be looking for candidates with experience generating reporter lines, live-imaging and experimental embryology. Application deadline: 25th Feb. tinyurl.com/33jbu8fa

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

🐸 are 🆒! ❄️☀️

Really looking forward to this visit, great way to start the year! Thank you @meiosis-mom.bsky.social for inviting me!

Cell cycles at double speed? Looks like those frogs are spiraling into party mode, happy xmas!

Had a great time this week with a wonderful group of researchers at our workshop on the physics of early embryonic cell divisions! Big thanks to everyone there, i.e. Johanna, Frank, Laura and Adam from @biologists.bsky.social, and to my co-organizer @kamenzlab.bsky.social! Let’s do this again!

Hi #SciSky! I’ve been hearing great things about you, happy to have this alternative to X/Twitter. Looking forward to seeing lots of fascinating science!
