Did you know that today is #InternationalCrabDay? 🦀 Started by The Crab Museum, this holiday encourages people to share photos of crabs so we’d love to see the Crabby Darwins you’ve created in Everything is Crab! Here's one I made earlier…

Finding molecular tags that localise fluorescent proteins to the cell membrane was the goal of our latest paper, now published in Development @dev-journal.bsky.social. The tags act as address labels, sending proteins to the cell membrane, where they highlight the shape and arrangement of cells. 2/9

Last day to submit an abstract! This is a meeting aimed at all career stages, but especially geared on early career scientists (PhD/postdoc), don't feel you need to have a perfectly polished story to present!

Pablo Villar et al discover male octopus mating arms are sensory organs used to find females, navigate internally to the oviduct & deliver sperm. From behavior to structure, these findings offer a framework for how sensory systems shape reproduction & species barriers www.science.org/doi/10.1126/...

Nice opportunity to join QMUL as a PhD student (or postdoc). Lee works on cool insect symbiosis projects, and I am co-supervisor on this one. Don't miss it if you're into microbiome / host-microbe interactions.

May 5th: if you are around London, please join the London #EvoDevo symposium at QMUL / Charterhouse campus, as usual we will have selected talks and post-event 🍻. A warm up for #EED2026 in Glasgow. Registration £0, more info here: londonevodevo.co.uk

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the “Example...” button for immediate candy and then click every button you can find).

BMC Biology is currently welcoming submissions of original research to the “Genome organization and evolution” Collection, which I am supporting as a Guest Editor. If interested check out the link: www.biomedcentral.com/collections/... Deadline: 26 March #GenomeEvolution @bmc.springernature.com

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

Anouk Necsulea, @maelledaunesse.bsky.social and myself are organising a symposium at SMBE this year. Send us all of your abstracts!!

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...

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

Gene annotations matter for downstream analyses: different structural gene-annotation pipelines yield markedly different orthology calls. We compare four strategies across species and argue for standards & QC before inference. Work led by @silviaprietob.bsky.social. Paper: doi.org/10.1093/bioi...

Pleased to share our latest paper led by @tomlewin.bsky.social, now out in @currentbiology.bsky.social! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions unite phoronids and bryozoans as sister groups. www.cell.com/current-biol...

Come join the #LondonEvoDevo network half day meeting, hosted at @ucl.ac.uk on Friday November 7th, 2025. Submit your abstract by Oct 27th (or your interest in joining) here: forms.gle/TRbdrCkQTcY2.... Friendly vibes and free registration. More info here: londonevodevo.co.uk.

Adding loops into a genome is a complicated and costly business for a cell. New findings suggest that it may be the reason that ancient life became complex. @philipcball.bsky.social reports: www.quantamagazine.org/loops-of-dna...

Chaetognaths have lost gene body methylation and shifted #5mC back to Transposable Elements. This reversion to the ancestral state is coupled with a simplification of DNMT3 architecture. We posit that trans-splicing might compensate. It is an honour to have contributed to this 20y struggle ⛰️.

A genome sequence and single-cell atlas of a marine worm species point towards bursts of gene emergence, duplication and loss as the drivers of lineage-specific body traits go.nature.com/4oAI2nf

New Nature study (co-authored by Queen Mary researchers) reveals that arrow worms evolved unique organs by inventing brand-new genes — not just reusing old ones. 🧬🌊 🔗 www.qmul.ac.uk/sbbs/news/it... @qmulse.bsky.social

After nearly twenty years in the making, our attempt at understanding what makes the chaetognath phylum so unique has finally been published! www.nature.com/articles/s41... with #LauraPiovani @dariagavr.bsky.social @alexdemendoza.bsky.social @chemamd.bsky.social and others /1

To all post-docs: The Genome Biology dept ‪@embl.org has an Independent faculty position. Fantastic place to set up your lab –great package: core funding, fantastic Ph.D. students, cutting edge core facilities & great colleagues. Closing date Sept 19th embl.wd103.myworkdayjobs.com/en-US/EMBL/j...

Happy to see our latest work out in @molbioevol.bsky.social. We revisit the evolution of 5-methylcytosine across neglected eukaryotic supergroups, establishing an ancestral repressive role silencing genome invaders, both transposons and viral elements👾: academic.oup.com/mbe/advance-... 🧵 1/7

Thrilled to share that our latest work on marsupial heterochrony is now online at @cp-devcell.bsky.social @cellpress.bsky.social @lab-turner.bsky.social @crick.ac.uk We used scRNAseq to understand the asynchronous progression of developmental programmes in marsupials www.cell.com/developmenta...

It was a pleasure to write a N&Vs on @danielibrahim.bsky.social's latest paper in @natgenet.nature.com. Enhancers tend to stay put even if their sequence changes beyond recognition. Quoting Il Gattopardo, everything must change so that everything can stay the same: www.nature.com/articles/s41...

🚨The formation of 3D chromatin hubs is a poorly understood phenomenon. I wrote a N&V about the excellent work Karpinska, Zhu and colleagues, from @mariekeoudelaar.bsky.social lab, who shed new light on the formation and function of these structures. rdcu.be/elPt3

Postdoc job opportunity! We're looking for ECR in evolutionary genomics to study the relation between intra-specific gene expression variability, polymorphism, and macro-evolutionary rates. We have the data in 3 fishes & amphioxus, just waiting for your expertise and enthusiasm! tinyurl.com/3aewk286

I’m very excited to share our work on the early evolution of animal regulatory genome architecture - the main project of my postdoc, carried out across two wonderful and inspirational labs of @arnausebe.bsky.social and @mamartirenom.bsky.social. www.nature.com/articles/s41...
