🚨 Late preprint alert! Why do biological process rates scale nonlinearly with temperature, deviating from the straight line on an Arrhenius plot? The key may lie in their inherent complexity! More in thread and here: doi.org/10.1101/2025...

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!
