- Reposted by Alex McDougallThis 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...
- Very happy to see this piece on the Tunicate Ciona published. Grateful to @alexandrejan.bsky.social and @chiaracastelletti.bsky.social for the Illustrations, and to @natmethods.nature.com for the opportunity to showcase our ever emerging model organism www.nature.com/articles/s41...
- Reposted by Alex McDougallWell, 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?

- Reposted by Alex McDougallFirst post on bsky for a very good news. Very glad to be awarded this HFSP with @chemamd.bsky.social & @baronelab.bsky.social to study the evolutionary biophysics of spiralian early asymmetric divisions ! @hfspo.bsky.social @cnrsbiologie.bsky.social @collegedefrance.bsky.social @cirbcdf.bsky.social
- 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!

- Reposted by Alex McDougallThe "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.
