#PASEDB community✨ Welcome to our newly elected PASEDB executive council members @kathykavanagh.bsky.social @ischneider.bsky.social @fishevodevogeno.bsky.social @fishfena.bsky.social Thrilled to have you join us and are looking forward to working with you!

🧬 10 @dfg.de-funded PhD positions at @goettingen-campus.de 🧬 ❗Focus: Evolution of gene regulatory networks & Wnt signaling in emerging models (insects, snails, flatworms, cnidarians). 💻 Methods: 'Omics, Bioinformatics, CRISPR/RNAi & Imaging. 📌Start: June 2026. #EvoDevo #Genomics #Bioinformatics

Check out our latest issue where we interview Cassandra Extavour, who studies the evolution of the genetic mechanisms employed during early animal embryogenesis to specify cell fate, development, and differentiation at Harvard University. www.cell.com/current-biol...

Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal. bioRxiv 2025.11.17.688882; doi: doi.org/10.1101/2025...

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9

Our paper on the role of neurons in Nematostella head regeneration is now out at @currentbiology.bsky.social Big thank you to all collaborators, it was a pleasure! Ectopic head regeneration after nervous system ablation in a sea anemone: Current Biology www.cell.com/current-biol...

Glad to see our phoronid genome study featured on the cover of @currentbiology.bsky.social! It shows how genome structure can be used to test competing hypotheses of nested topology and how derived structural changes provide evidence for monophyly. www.cell.com/current-biol...

Looking forward to giving this talk. See you all on Tuesday!

Join our upcoming course on cutting-edge evolutionary & genomic methods for Evo-Devo studies! We'll cover: comparative & single-cell transcriptomics,ATAC-seq, phylogenomics, comparative genomics, gene regulation, and much more Spots still available: sites.google.com/view/evodevo...

Happy partially muscled skeleton screaming before vanishing day to all those who celebrate.

I will be participating in this EvoDevo course in Madrid, organised by @patrialvarezcam.bsky.social and other colleagues. sites.google.com/view/evodevo... I will be covering scRNA-seq, other topics are transcriptomics, ATAC-seq, phylogenomics Registration closes on Nov 20! Dates: Dec 15-18

Happy to share Jialin's first publication. She did a great job exploring the transition to land in animals. Co-supervised by the great Jordi Paps and me and in collaboration with Davide Pisani and @phil-donoghue.bsky.social

The Marine Biological Association is now accepting applications for the Molly Spooner Studentship, a paid summer research opportunity for undergraduate students interested in hands-on marine biology.
