Here’s the nervous system of a juvenile sea star ⭐️
Green = acetylated tubulin, red = nuclei

As a biologist working on the cellular and molecular development of gills, I love seeing gill architecture inspire solutions like this plastic-filtering technology....truly inspiring 🦓🐟🔬
Mikroplastik stellt eine große Belastung für Mensch und Natur dar. Forscher haben nun einen Mikroplastikfilter für Waschmaschinen entwickelt, der sich an den Kiemen von Fischen orientiert. So können selbst winzige Kunststoffpartikel besonders effizient aus dem Abwasser gefiltert werden.

To build the body plan of an animal, cells must adhere to one another via cell-cell junctions. We now know these assemble as punctate protein complexes containing thousands of proteins, but how this occurs remains mysterious. 1/n 🧪

Live muscle precursors on a pupal fly testis (Lifeact-eGFP, 🔥-depth-coded).
It's special because this is on the poster for the @sfb1348.bsky.social Meeting in May — my first time being featured as a speaker on a poster! 😀
Feeling very grateful & excited!
