Also not clams but fellow travelers: clam shrimp! An ancient group, with species inhabiting extreme environments like vernal pools where they wait for months drying out, freezing, and exposed to extreme salinity. I enjoyed seeing these California clam shrimp at Jepson Prairie. (241)

Big thank you to @biologists.bsky.social, @focalplane.bsky.social and @the-node.bsky.social for sending me the printed poster of my image from their imaging contest earlier this year! 🔬 It finally found a spot in my new flat — I couldn’t be happier to have this piece of science art on my wall❤️💙

I found an original way to play with 3D data on ImageJ : progressive color coding! I'll share the script soon #FluorescenceFriday #Sciart #MicroscopyMonday

Dresden researchers @paveltomancak.bsky.social @bruvellu.bsky.social, Carl Modes, @cuencam15.bsky.social ‬ & colleagues published in @nature.com that a tissue fold in fruit fly embryos buffers mechanical stresses & may have evolved in response to mechanical forces. www.mpi-cbg.de/news-outreac...

Beautiful atlas of fish gill development from the Lecaudey lab. There are few structures more amazing in biology than gills! journals.biologists.com/dev/article/...

🚨Why can’t mammals regenerate legs or arms like frog tadpoles or salamanders? Our preprint tackles (part of) this BIG question with surprising findings about oxygen sensing 🔗 www.biorxiv.org/content/10.1... Happy New Year, everyone! 🎉 🐭 vs 🐸 #evodevo #regenerative #cellbio 🧵👇

This thread below is criminally under-liked and under-shared! Young #Drosophila researchers (PhDs, postdocs, and early-career Drosophilists): fill out the survey by Sept 1st to get matched with a mentor who can support you with your career. Established Drosophilists, like/share Shefali's Thread ;)

Intermediate mesoderm isn't the sole contributor to nephrons in zebrafish-new manuscript out showing somites are a source of nephron progenitors! Very cool, dogma challenging study led by Alan Davidson's group. Many fun discussions were had-grateful for the inclusion! www.nature.com/articles/s41...

first data from the new LLSM in PertzLab @olivierpertz.bsky.social! i always thought nuclei were spherical but they are pancakes???? so much more to see in 3d, but data volume produced is insane, we will have to rethink our analysis pipelines. tips welcome! here shown in @napari.org

Marine protected areas can protect fish and maintain healthy ecosystems. As demonstrated by two related papers in this issue, however, such areas are only effective against illegal fishing when established limitations are enforced. Learn more this week in Science: scim.ag/3H6oeXQ

Happy #MicroscopyMonday! Here is another gorgeous lung image from a Shh lineage tracing survey by @stjuderesearch.bsky.social postdoc Christina Daly! This is an E18.5 🐭 lung with magenta showing non Shh-expressing cell types and membrane GFP marking Shh-expressing cells. 🤩 🧪 🔬 👩‍🔬

Drosophila testis or a fluorescent snail ? 🐌 🐚 I can’t tell the difference anymore🌀

Such an honor to be featured by @focalplane.bsky.social , especially on my favorite day of the week: #FluorescenceFriday! 🔬 Below for reference, a picture of the full hydei testis with the musculature stained (depth-coded) taken together with @saraheclark.bsky.social #cellbio #devbio #microscopy

Our featured 🔬image this #FluorescenceFriday is of a portion of testis from Drosophila hydei, acquired by @maikbischoff.bsky.social. Learn more about the image and Maik’s research ⤵️ focalplane.biologists.com/2025/07/18/f...

Happy #FluorescenceFriday! These are cultured fibroblasts imaged on a confocal microscope by postdoc Christina Daly. She is trying to understand how cells grow long signaling filopodia called cytonemes. Examples are visible extending from the orange cell in the image. 🤩 🧪 👩‍🔬

For #FluorescenceFriday I'm sharing the fantastic work of postdoc Sarah McLarnon! A follow up to our '23 Development paper where we asked: Does precise vascular patterning matter for function and what happens after ischemic injury? The results were surprising! journals.physiology.org/doi/full/10....

😍 I just love timelapse movies. It’s unbelievable that all of this happens in such a tiny fly! These cells don’t just move—they shape the unique spiral structure of the 🪰 testis. Amazing post by @maikbischoff.bsky.social — proof that science is art!!

For today's #FluorescenceFriday I'm thrilled to share that ScienceAdvances was so nice to pick my picture as this week's featured image! It's actually a still of a video😊 Check out the paper to learn more science.org/doi/10.1126/... #cellbio #devbio #cellmigration #science Thank you @aaas.org

It’s a quill? A sea pen? No—it’s a gill filament! 🪶🪸🐟 Under the microscope, this fish gill structure looks just like a sea pen. Fascinating how nature keeps circling back to the same shapes. Want to learn how gills develop? 👉 www.biorxiv.org/content/10.1... #FluorescenceFriday #Zebrafish

What a remarkable achievement. This guy is a true genius 🪰👨‍🔬🔬 check out the beautiful illustrations and images. Congratulations!
