National Egg Day celebrates the humble breakfast egg. But at the Marine Biological Laboratory, we’re taking a different spin and highlighting the eggs that help scientists better understand life itself.

Introducing a Clytia planula cell atlas, and demonstrating broad-level relations with medusa cells via another updated atlas.

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...

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...

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?

Admirez la magie du développement cellulaire des organismes marins ! 3/4

This Earth Day, we’re honoring the planet through the power of genomics—preserving biodiversity, protecting ecosystems, and decoding the DNA of life to shape a sustainable future. Happy sequencing! 🌍 #earthdayeveryday #earthday #earth #genomics #genome #DNA #biodiversity #conservation

First 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

Barone Lab@baronelab.bsky.social · last yr.

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.
