Meet our keynote speakers at #EZM2026! 13th European Zebrafish Meeting, taking place in Vienna, July 7–11. 🧬 Pavel Tomancak (Dresden) has made key contributions to evolutionary developmental biology and tissue morphogenesis, advancing our understanding of how complex biological forms arise.

During this time, he published a more detailed table of zebrafish cleavage and also studied karyokinesis. But that’s not all: in a collaboration with Warren Harmon Lewis, then at Wistar, they produced what is probably the first “motion picture" of zebrafish development. (6/7)

Wow, this sounds like an incredible opportunity!

Last couple of days to vote for your favourite 'Featured image' from 2025 ❤️🔬! focalplane.biologists.com/2025/12/19/v...

We're in love with this cover image! 🧡 Part II of our Special Collection celebrating the Centennial of the Discovery of The Organiser is here. This issue focuses on the work presented at the Centennial Symposium at the University of Freiburg in September 2024: www.sciencedirect.com/journal/cell...

#Mastodon, the Command Center for Large-Scale Lineage-Tracing Microscopy Datasets, is finally heading for publication (well, let's see). To #cite or not to cite shall no longer be the question 🙃, because the #preprint. Software is available in every #Fiji near you. www.biorxiv.org/content/10.6...

At first glance, looks like a Gray–Scott reaction-diffusion But it’s a fertilized starfish 🥚: proteins self-organizing into spiral waves across the membrane Same dynamics seen in ❤️/🧠/🌊, even quantum fluids. Universality in action! #ComplexSystems news.mit.edu/2020/growth-...

Useful new tool for imaging and keeping track of large scale movements in embryo development!🔬

Beautiful images! Save some for the YEN 2026 image competition ;)

Mark your calendars! The next SFB 1348 International Meeting will take place in #Münster from May 27-29, 2026, with a focus on #Mechanochemical signals at cellular interfaces. Stay tuned for more details and updates at www.uni-muenster.de/SFB1348/en/m...

Happy #FluorescenceFriday. This beautiful video shows slice by slice section of a zebrafish embryo's head. The embryo is almost completely transparent, proving that zebrafish is an amazing model system for microscopy. Brightfield, red = actin, blue = DAPI 📹: Postdoc Matyas BL (@Mongera lab, UCL)

Searching for physical principles of morphogenesis In this #OpenAccess Spotlight, Nikolas Claussen, Fridtjof Brauns and @streichan.bsky.social highlight the ‘physics of development’, focusing on the interplay between quantitative experiments and mathematical theory doi.org/10.1242/dev....

I don’t always manage to get the cochlea out… But I love it when I do! #FluorescenceFriday

Can't believe it — my first‑author paper is out and my image graces the cover of @dev-journal.bsky.social 🎉 Here, we reveal how early developmental programs shape and maintain #zebrafish gill architecture throughout life 🔗 journals.biologists.com/dev/issue/15... #FluorescenceFriday #LifelongDevSI

Happy (and spooky) #FluorescenceFriday Switching from frogs (which are underrated btw) to zebrafish has really made me appreciate transparent tissues! 🐟 28 hpf, ⚪ nuclei, 🔴 F-actin

🏆 First Prize – DevBio Art Contest 🖼️
“A Model Meeting” by Karla Akari Garcia Inspired by The Quaker Meeting, this watercolor honors animal research models, from mouse to axolotl, that have advanced developmental biology 🎨 A tribute to science’s often unsung heroes. #DevBioArt

Amazing day at #GastrulationReloaded with thought provoking science and jaw dropping methods. Also, for no reason at all, re-posting this open Collection: www.nature.com/collections/... Don’t sweat the deadline, we’ll extend it and I’ll add relevant papers that come to me @natcomms.nature.com

Very sad news, John Gurdon has died. A developmental biologist's developmental biologist, Nobel prize winner His work is the foundation of much of today's dev & stem cell bio. An inspiration to many, including me. Always asking questions & wanting the answers www.magd.cam.ac.uk/news/profess...

Happy to share the Biodiversity Cell Atlas white paper, out today in @nature.com. We look at the possibilities, challenges, and potential impacts of molecularly mapping cells across the tree of life. www.nature.com/articles/s41...

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 🧵...
