Tug-of-war between cortical and cytoplasmic forces shaping planar of 4-cell stage embryos https://www.biorxiv.org/content/10.1101/2025.11.24.690087v1

@katecavanaugh.bsky.social you have to explain me that one
(the physics)

Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal.

New research has unravelled the mystery of how microscopic cilia choreograph their “Mexican wave”, enabling marine creatures to swim.

Cilia are tiny, hair-like protrusions found in many organisms. Yet despite decades of research, the mechanisms of cilia coordination remained disputed.

Modeling whole ascidian embryos for #forksningdagene 😉🧪🧬🔬#devbio

We all know scientists who are also musicians In fact, one of my favorites just dropped a new album last month. I was surprised me, though, since she died over 800 years ago. Turns out she might also be the first woman to ever write about developmental biology. 🧵 1/16

We have shared detailed protocols for the expression, purification, and use of VitelloTag-Cas9 (in sea stars) on our website. We hope that this will be a useful starting place for working in your own favorite organism!

wise words from a wise man.
today's world is missing you

Good news alert! We are among the 2025 HFSP awardees! In a fun project developed together with @turlierlab.bsky.social and @chemamd.bsky.social we will study the polar lobe of spiralian embryos. Very excited about the opportunity to explore this unique mode of asymmetric cell division. Stay tuned!

wow, I wish I could inject 35000 ascidian eggs...
Congrats to them

My first post on bluesky. I am very proud of it because it will happen in the beautifull Villefranche sur Mer.
And it all organised by Angelica Miglioli at LBDV (and soon at QMUL)
