Congratulations to Mellone Lab graduate student Tyler McDermott on successfully defending his PhD thesis! 🔬🧬 His work reveals how a conserved retroelement targets centromeres in Drosophila, shedding light on a phenomenon that occurs across taxa. Preprint coming soon! #PhDdone #proudPI

I love these PIP3 biosensors because it labels the plasma membrane so well. You can see the cell's edge so clearly along with any intracellular vesicles. Also, this cell is so blebby. This video was taken when I was still working on endocytosis :D Good old times! #FluorescenceFriday

✨For this #FluorescenceFriday we are highlighting 10 amazing images of development from the Young Embryologist Network 2026 Image Competition! Follow the hashtag #yenimagecompetition for full details. 📷🔬

How does cells in a notochord pack together? And how packing affects the physical interactions between cells? Using physical modelling, Lubkin et al found a relationship between cellular packing and tension, pressure, and eccentricity. Check out the paper for more details: doi.org/10.1016/j.cd...

Nic Janto served up this delight for #FluorescenceFriday A fish gut where he visualised all the associated leukocytes in magenta. I always find it so striking to see how blood cells patrol and occasionally integrate within the gut epithelium.

Unlike other organisms, Clytia medusae can repair damage so rapidly you can actually watch small wounds close within minutes. Larger wounds heal in less than an hour, a rate of recovery humans can only dream of. And no scar tissue is formed. 🔗 go.mbl.edu/jellyfish

🦠🧬🔬Bacterial aggregate in Potomac River water!🦠🧬🔬 DNA staining imaged the fluorescence of ~1,600 bacteria! The diameter is 1,000 um. Aggregates allow bacteria to survive chemical, physical, & biological stress. #FluorescenceFriday #Microscope #Microbiology #Bacteria

Another #FluorescenceFriday. When the world is going crazy, I find some peace watching at these myeloid cells (🔴) going about their day. They exist in tissue surrounded by other cells (🔵), and you can see them popping up and down, going in and out of plane as they explore their surrounding.

An intact human heart, rendered transparent. Because disease doesn't happen in 2D. Whole-organ tissue clearing and light-sheet microscopy reveal coronary vessels (magenta) and atherosclerotic plaques (gold) across the intact organ. More at: shorturl.at/iqTBh 🫀🔬 #FluorescenceFriday!

🐟 and 🫀

Heart injuries can often be fatal, yet many animals can regenerate their 🫀 without leaving any scar, while others like 👨 cannot. Part of the reason lies in how the extracellular matrix is regulated. Patra et al discussed in details how this works and what we can learn from 🐟 doi.org/10.1016/j.cd...

✨ Excited to host invited speaker Roberto Mayor (@mayorlab.bsky.social) at #2026SDB in Las Vegas! 🎰🃏 His research explores morphogenesis, focusing on how cells migrate, interact, and generate diverse cell types during development. 🧬✨ #devbio

My image "The phases of gastrulation" made it to the top 10 in this year #YEN2026 image competition! I took this video of a gastrulating 🐸 embryo while testing a new microscope in the lab. One of the rare #devbio theme videos I got. Check out the others here: thenode.biologists.com/results-of-t...

Beautiful images from all of your favorite model systems: 🐟 🐸 🐭 👨 🐥 Check them out!

This #MicroscopyMonday is a developing Apple Snail embryo. On the left is the shell, the middle the body and the foot at the bottom. On the right the head with the eye (green circle) and the tentacle bud. 🐌 (@planaria1.bsky.social Lab)

We are excited to announce the results of the YEN 2026 Image Competition! Thanks to all who submitted an entry. This year amazing work has been shared with us complementing our perspectives talks on art+science. We congratulate the winners of the YEN and public votes! #yen2026 #yenimagecompetition

Our work on size scaling for centrosome positioning in early embryos is now out in @currentbiology.bsky.social Congratulations to Aude et al. ! www.cell.com/current-biol... @cnrsbiologie.bsky.social @ijmonod.bsky.social @upcite.bsky.social

Stunning microscopy work from the Scarpa lab!

We are thrilled to announce our new preprint from the wonderful @sorayavillaseca.bsky.social Ever wondered how cells squeeze through tiny spaces in embryos? Neural crest cells use Dynein to transport their nucleus along microtubules. Check out the preprint!! www.biorxiv.org/content/10.6...

The awesome trio of @lmescu.bsky.social @fpichaud.bsky.social and Fernando Casares (and their teams) are on fire Fly eyes represent 'programmable metamaterials'; human engineering principles pre-exist in biology www.nature.com/articles/s41...

☕Mani, Tardif, Rossier et al. show that mechanical stress triggers caveolin-1 release from caveolae, enabling its diffusion in the plasma membrane and interaction with signaling effectors to regulate intracellular signaling. 👉https://rdcu.be/frvPe www.nature.com/articles/s41...

👋In this month's editorial, we introduce a Collection of articles in the area of #StemCell - based #embryo models. The collection will be updated as we publish new content. 👉Read here: rdcu.be/frN7h www.nature.com/articles/s41...

#2 Close collaboration with @rocha-lab.bsky.social across institutes. @catfigueiredo.bsky.social shows that neurogenic progenitors in the developing retina can respond to cell death with an unexpected self-renewing division. I am sure Mauricio has more to say :-). www.biorxiv.org/content/10.6...

In our Special Issue At the interface of Immunology and #devbio, Bellaïche et al discussed the surprising role of Toll-like Receptors in modulating tissue mechanics and tissue boundary segregation. We love it so much, we made an accompanied video of TLR7 😍 🔗: www.sciencedirect.com/science/arti...

Happy #FluorescenceFriday! Eye of a zebrafish embryo🐟

Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

New in @natmethods.nature.com: a new human stem cell model of EMT lets us watch cells transition in both 2D and 3D and shows human stem cells can undergo the transition differently depending on how they are grown. 🔗 https://doi.org/10.1038/s41592-026-03096-9
