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/...

Call for a group leader in Evolutionary Biology The IGFL @igflyon.bsky.social in Lyon, France, is recruiting a group leader in Evolutionary Biology. An exciting place for exploring the interfaces of evolution with physiology and development. #EvolBiol #ecoevo #evodevo tinyurl.com/evolbiol

Single-cell transcriptomes of acorn worms show that larval & adult body plans are composed of distinct cell types. Larval & adult cells evolve quasi-independently! @paulbump.bsky.social @laurentformery.bsky.social @lowelab.bsky.social @planaria1.bsky.social www.nature.com/articles/s41...

Fantastic news!!! My project ECHINODEV has been awarded an ERC starting grant 🥳🥳⭐ We will use several echinoderm species to study animal body plan evolution! Reach out if you are interested, we will be looking for PhD students and postdocs 😀

Good to see our results from xenacoelomorphs (doi.org/10.1038/s415...) made it into the new BBC "Evolution" documentary! www.youtube.com/watch?v=tgjZ...

🔬 Meet Michalis Averof, ZooCELL PI at IGFL @michalis-averof.bsky.social What sparked his interest in EvoDevo? What keeps him curious after all these years? And what does he hope to discover next? 🧵 Read on to get to know Michalis through his own words. #ZooCELL#EvoDevo#genomics#IGFL#MSCA

Fantastic seminar by Chris @lowelab.bsky.social. It’s been a real pleasure having you at @szndohrn.bsky.social these days. With @arnonelab.bsky.social

🔬 Meet Ina Arnone, ZooCELL PI at @szndohrn.bsky.social In this Q&A, she shares how she discovered EvoDevo, the big questions driving their research and her passion for mentoring the next generation of scientists. Follow the thread to learn more. 👇 #MSCA #ZooCELL #EvoDevo @arnonelab.bsky.social

Very excited to see our preprint on the monoaminergic signaling system in sponges (www.biorxiv.org/content/10.6...) featured by @qedscience.bsky.social. This highlights the importance of studying early-branching animals to piece together how the first animal cell types communicated with each other.

Published today in Open Biology, our investigation of the evolutionary and functional significance of neuropeptide cocktails. Congrats to my co-author Nayeli Escudero Castelán and thanks to @leverhulme.ac.uk and @ukri.org BBSRC for funding. royalsocietypublishing.org/rsob/article...

Congratulations to @kremnyovs.bsky.social, @tclebedeva.bsky.social and @hejnol.bsky.social - this is a fantastic paper. www.nature.com/articles/s41... Very happy to have been part of this collaboration.

What is the evolutionary origin of the organizer? New work from @kremnyovs.bsky.social, @tclebedeva.bsky.social & Hejnol Lab @uni-jena.de reports the blastopore lip of the #ctenophore Mnemiopsis leidyi, a member of the evolutionary sister group to all other metazoans, exhibits organizer activity.

61 species, 13 phyla, one simple geometric rule that appears to set when every embryo starts speaking through its own genome. 🧬 Panagiotis Giannios highlights a recent #preprint from @mirimiam.bsky.social & collaborators. #EvolutionaryBiology #preLight: prelights.biologists.com/highlights/e...

(1/2) What a fantastic week for the Arnone Lab at #EED2026 in Glasgow! Our lab’s work was showcased through contributed talks by @perievodevo.bsky.social in S19 and @mlrusciano.bsky.social in S02, as well as an invited talk by Ina in S15.

A fossil nervous system meets modern neurobiology. We found that a living comb jelly preserves neural architecture remarkably similar to those inferred from Cambrian fossils over 500 million years old 🤩. www.biorxiv.org/content/10.6...

Issue 8 is now complete! On the cover: Embryos of diverse animals & choanoflagellates expressing different fluorescent reporters, from a project to identify membrane-localising tags across diverse organisms. See the Techniques and Resources Article by Karapidaki et al. doi.org/10.1242/dev....

Do you want to know when your favorite species activates its genome? Just input its genome size (🧬 in bp) and egg volumen (🥚 in um3) here! ZGA_onset = -2.37 * log10(gDNA/EggVol) + 11.74

I am honored to have been involved in this super cool open-science project. Thanks, Michalis!

Thrilled to be part of this beautiful work! Stay tuned😉

Thrilled to share that I’ve been awarded a FIS-3 Advanced Grant (ERC-inspired) to study the evolution of neurogenic GRNs. Recruiting soon: 4 postdocs + 3 PhDs Press release in Italian — to decolonise scientific language 😄 magazine.unibo.it/it/articoli/... Email me if interested in joining the lab

Coolness alert!! If you didn’t attend this fantastic microscopy course last year, make sure you do so this coming April! Don’t miss the chance to learn from the best in the field. Plus, the course takes place at @szndohrn.bsky.social, one of the most iconic marine stations in the world!

I am very happy (and a bit scared) to present to you what we have been working on over the last 4 years. This manuscript is exactly what I dreamt of when I started the lab and I could not be happier and prouder of the outcome!

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/...

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
