Beautiful image 😍

Found this cute little 1” #goby living on a feathery #SeaPen today while looking for something completely different. Tomorrow will be my first day not diving in 3.5 weeks - gotta head to the city to restock “supplies”🍷

Have a nice #FluorescenceFriday!
This is pollen from pine tree, imaged from auto-fluorescence by confocal microscopy
the LUT is "KTZ bw DarkGold" 🔥

For this #FluorescenceFriday 🔬

Rainbow shading of a confocal micrograph of a developing mouse neural tube. The protein actin is stained and colored in rainbow to indicate depth in the section.

Happy #FluorescenceFriday! This is a maximum intensity projection of depth shaded actin (🌈) in a section from an E9.5 🐭 neural tube (NT). 🔬 by postdoc @christinaadaly.bsky.social 👩‍🔬 🧪 Image shows the floor plate and lumen of the developing NT.

I’m happy to share some plugins I’ve been developping this summer: "Channels and Contrast" and LUTs Manager!
I can’t find new bugs and ideas by now so I need your help to please test them in your machines and report bugs, feedbacks and ideas! forum.image.sc/t/looking-fo...

One out of many reasons why gills fascinate me 🔬🧬

PS: A recent study showed that the outer ear cartilage shares gene regulatory programs with the gill filaments of fishes and amphibians — the gills program has been repurposed to create parts of the human ear 👂

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 🧵...

What if fish gills —often overlook —hold secrets about development, patterning, and function?
We uncovered how early patterning shapes adult gill architecture.

Development does not happen in isolation! Material properties, geometry, stiffness, fluid flows...can all steer how development unfolds. If you’re exploring these kinds of questions, we’d love to see your work @dev-journal.bsky.social

Image of a fluorescently labeled adult mouse kidney showing AQP2 staining of collecting ducts and connecting segment in green and alpha SMA staining of the arterial tree in magenta. The collecting ducts look like squiggly branches.

For this #FluorescenceFriday, a gorgeous image of an adult mouse kidney labeled with AQP2 and alpha SMA antibodies. AQP2 (green) marks the collecting duct and distal connecting segment while SMA marks the arterial tree. Courtesy of talented postdoc Sarah McLarnon.

Sea urchin metamorphosis is maybe one of the most radical event in developmental biology. In just about an hour, these little pluteus larvae completely reorganize their entire body plan.
