#stuffthatmatters Congratulations!

SO HAPPY to share our new paper in @currentbiology.bsky.social! Using volumetric EM, we found daily shifts in synapses, vesicles, and mitochondria that accompany neuronal remodeling, linking structural plasticity to changes in how s-LNv neurons influence their targets 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...

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...

🧬 PhD Position: Evolutionary & Comparative Genomics 🕷️ Join us at @uni-goettingen.de for a 3-year PhD (65% TV-L E13). We will investigate the genomic & phenotypic impact of gene duplication across 233 arthropod genomes! More infos 👇 and s.gwdg.de/eDrAAY #Evolution #Genomics #Bioinformatics

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...

Our work on Naegleria Myosin 2 is out! Naegleria encodes 3 Myo2s which contract its actin network—the first evidence of contractile Myo2 outside of Amorphea. Myo2 is actually widespread in Naegleria's relatives and correlates with fast cell crawling. Read more: www.cell.com/current-biol...

Me to myself this morning, realizing it's mid-month and I hadn't done anything for #InsertAnInvert2024 in 2025 yet: "You're not allowed to do any other hobbies until you draw."

You only have one more week to submit your abstract for 'Collectivity in living systems: emergence, function, and evolution' 👉 s.embl.org/ees26-01-bl Don't miss #EESCollectivity which will explore how collective behaviours arise from fundamental principles across biological systems🦠🐒🧬

My book 'The Tree of Life' is published in the USA and Canada today. Available as book, on kindle and as audio. I would be really grateful for reposts. www.amazon.com/Tree-Life-So... www.amazon.ca/Tree-Life-So...

On the importance of marine labs: "Marine laboratories encourage exploratory and creative thinking... Against the current backdrop of anxiety about the future of science, the scientific community and public need these places now more than ever." Could not agree more... 🌊 🧪🥼🧫

If you believe either that Franklin discovered the double helix, and / or Watson and Crick stole her data, ask yourself how you know this. Then take a read of this article.

Happy to share our last paper in PNAS! Woo-hoo! 🥳 This article supports once more the hypothesis that sponges (and therefore animals) emerged about 100 million years before the Cambrian, and before we find any animal fossils. www.pnas.org/doi/suppl/10...

What happens if your asexual reproduction goes wrong? For instance, you can grow a head instead of a tail. But if you're a flatworm, it's not that bad - as we showed in our newest paper published in the Proceedings of the Royal Society B: tinyurl.com/4dnp2ffz

Very happy to see our paper published online natcomms.nature.com. Thank you to @wellcometrust.bsky.social for funding this work during my time with @robklose.bsky.social and David Booth! Thanks also to collaborators @garcialabms.bsky.social @alexdemendoza.bsky.social and the other authors!

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️ Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

How did the anus evolve? Researchers led by evolutionary biologist Prof. Dr Andreas Hejnol from #UniJena, in collaboration with the University of Bergen, showed that in sea worms (Xenacoelomorpha), the sperm duct exhibits the same gene pattern as the later rectum. ➡️ www.uni-jena.de/en/367301/th...
