Our work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l

Congratulations to the all team for this amazing work understanding how the cis regulatory elements and chromatin organization are relevant in the ancestral regulatory features of animal genomes. This study started with a collaboration with José Luís Gómez Skarmeta from #CABD.

I am extremely proud and happy to announce that another paper from my PhD days has just been published in @natecoevo.nature.com on evolution of genome and gene regulation thanks to all the amazing people involved. Check the paper out at: www.nature.com/articles/s41...

Extremely happy to see this work out! I am deeply grateful to everyone who contributed, and especially to @danivoronov.bsky.social, who took the lead! @arnonelab.bsky.social sky is the limit! 🌊🔬🧬

When you combine a brilliant scientist with strong grant support, the result is magic. This is exactly what the NEF project will deliver, nothing less!

First #MicroscopeMonday contribution! Early auricularia larva of Holothuria tubulosa (4 days post-fertilisation, dpf) shown in brightfield (left) and with DAPI-stained nuclei (right, blue). Same larva. Same view. Bonus: this was also my first DAPI stain, imaged on an inverted microscope.

Researchers discover an "all-body brain" in sea urchins - @mfnberlin.bsky.social www.museumfuernaturkunde.berlin/en/museum/me...

Our study, just published in #ScienceAdvances and funded by @hfspo.bsky.social, explores the post metamorphic cell composition of the sea urchin juvenile, revealing that its body is head-like. Long considered brainless creatures, they’re all brain instead! www.science.org/doi/10.1126/...

I am beyond excited to share that my postdoc project @szndohrn.bsky.social and the @arnonelab.bsky.social is now available in #ScienceAdvances @science.org. www.science.org/doi/10.1126/...

Thrilled to share my newest perspective article with @arnonelab.bsky.social in @dev-journal.bsky.social journals.biologists.com/dev/article/...

Our lab studies how animals regenerate their body, e.g. how crustaceans regenerate broken legs. One of our aims is to understand if regeneration re-uses the gene networks that built the legs in the first place. Arthur Monternier, an artist in our team, captured the question in this cartoon.

First neurons didn’t appear overnight. We trace their roots to ancient secretory cells - showing how lifestyle & behavior shaped the evolution of first synapses.🧠🌊 #Evolution #Neuroscience Our latest in @natrevneuro.nature.com Link: rdcu.be/eMX3E @jeffcolgren.bsky.social @msarscentre.bsky.social
