This great piece by @lionlchristiaen.bsky.social highlights the sea squirt Ciona as a versatile and tractable model for marine sciences, from cells to ecosystems 👏🧪 Read it in @natmethods.nature.com ⤵️ www.nature.com/articles/s41...

Well, we also find increased contractility in the aged embryo also correlates with faster compaction at the 8-cell stage. Could this be a possible metric to see which ones will implant?

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!

The "superpower" of sea urchins is the fact that a single female can produce millions of embryos. In the next day or so we will share a new method to analyze gene expression methods in these embryos using a fully automated, open platform.
