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/...

Apply now to join us in December for our workshop "Rethinking Cell Differentiation and Development: A Unicellular Perspective". This will be an intimate meeting (30 people total) and we hope will be a great place to discuss this topic.

Apply for a funded early-career researcher place at our Workshop on Rethinking Cell Differentiation and Development: A Unicellular Perspective, organised by Elena Casacuberta & James Gahan @jgahan.bsky.social. Find out more www.biologists.com/workshops/de... #BiologistsWorkshops

Just heard that HHMI will start a new Masters Investigator program, for those who are 55 and above. They have done so much for early career scientists, and now supporting the more mature. It is a 10-year non-renewable funding mechanism. The catch? You have to promise to leave science afterwards!

This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

Voici le tout nouvel article publié de notre équipe @stemdevevo.bsky.social !

We are continuing our efforts at iterative expansion microscopy of loricate choanos. Not only does the lorica expand, it seems you can iterate expansion pretty much infinitely. Here’s our latest - incredibly, it expanded to macroscopic size! #ProtistsOnSky

I'm hiring! I have 2 open positions: 🔬 Postdoc 🧪 Research associate We study how animal multicellularity evolved by exploring the molecular logic of cell adhesion using cell biology, 'omics, and tool-building in non-model organisms. Come join us! Details and application links 👇 Please repost

🤖AI tools for peer-review? I want to share my experience using q.e.d. science (www.qedscience.com), a reviewing tool with high-profile endorsements. I will report results and my impressions from the use /1

Our work on chromatin evolution in brown algae is finally out! This is also my first "co-first author" paper!! I’m excited to share what we found 👇

I'm happy to present our new tool, EpiCure, a napari plugin to ease correction of segmentation and tracking of epithelia movies, developed in @devstempasteur.bsky.social

It absolutely makes sense but incredibly important to quantify and test. Note that the Chatbots supported AITA posters 50% of the time (telling people they were not the A). And most of those are not edge cases!

Happy to share the heroic effort of @gaellel.bsky.social to reduce our segmentation pain through EpiCure (Epithelial Curation), a napari plugin easing the curation of epithelial segmentation developed with several groups of @devstempasteur.bsky.social. www.biorxiv.org/content/10.6... See more 👇

Abstracts have been reviewed and participants will soon be notified for CGUE2026! The program will be finalized in the coming weeks. Please head on over to the registration page to secure your spot!! Invited speakers - wait until you hear from us for more information! Registration is open!

Interesting study in @science.org: asking chatbots for advice in social interactions decreases prosocial behavior: www.science.org/doi/10.1126/... (basically, chatbots will always affirm your reactions in social situations; on the long run, this makes you more selfish and self-righteous)

Choanoflagellates — our closest animal relatives — form multicellular colonies in two ways: cell division AND aggregation. This previously unknown "mixed multicellularity" suggests our animal origins are more complex than thought. 📄 @thibautbrunet.bsky.social ↘️

New piece on the mechanics of squamous epithelial shape transition highlighting the role of tensile forces, force transmission by Dumpy & elastic resistance by the ECM in the developing wing. Terrific work from Stefan Harmansa @morphomechanics.bsky.social with Alex Erlich🍾👏: tinyurl.com/2p58b3w3

“I shall send off the manuscript today or Monday. It is an extremely poor affair; I must say something & have nothing worth saying.

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

Excited to share our PNAS paper on the genome evolution of an early-diverging #amphioxus, Asymmetron lucayanum! There is a long and twisty story behind this work, which also explains the username choice of the lab PI @iamphioxus.bsky.social . 😀 @pnas.org www.pnas.org/doi/10.1073/...

A sea anemone looks very different from a coral, despite belonging to the same broad biological group. A new study from EMBL researchers and their colleagues sheds new light on how diversity arises in body shapes in the animal world. www.embl.org/news/science...

Hello epithelia enthusiasts! I’m @inesfournon.bsky.social and I study epithelial mechanics in sea anemones 🪼 Did you know epithelial cell extrusion had never been described outside bilaterian animals before? Well… not anymore 👀 Read ⬇️🧵1/9

We are looking for a new group leader to join the IGH (Montpellier, France). I can’t wait to meet my future colleague! Apply :-) More infos here: igh.cnrs.fr/join-igh-as-...

Super stoked that we (with @viktri08.bsky.social, Michael Stumpf and Miguel Concha) got awarded an HFSP research grant! Looking forward to diving into this exciting if a bit crazy project.

One of the joys of working @pasteur.fr is that you get to be constantly in awe of the great science your colleagues do. Read below for a cool genetic/archeological detective story on the spread of farming in South America (with a rare stop-motion abstract!)

We’re looking for a new team member! 🚀 Only 3 more weeks to apply to the fantastic Vienna BioCenter PhD program

Expansion microscopy of a loricate choanoflagellate, generated by Mylan Ansel in our lab 🤩 (yes, the lorica expands. No, we don't understand how either)

Our study on shape diversity in cnidarians is now published. The final version includes extensive new data that substantially extend the original bioRxiv preprint. Congrats to everyone who contributed to this work! www.cell.com/cell/fulltex... @embl.org

Choanos on an hydra tentacule 🧐

Hello from sunny @institutpasteur.bsky.social

As emerging models gain traction during this uncertain funding landscape, the need for sustainable and scalable approaches is pressing. Our effort to implement accessible genetics in choanoflagellates and share our strategy is now out. We hope the community finds this helpful and invite feedback.

How did farming reach the Southern Andes? Through migration or cultural transmission? Our new paper in @nature.com combines ancient DNA, isotopes, archaeology & paleoclimate to reconstruct 2,000+ years of history in Uspallata, Mendoza. www.nature.com/articles/s41... A Thread🧵 (1/25+)

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky

I am very happy to share that I've started my new position @upcite.bsky.social and opened my lab @institutimagine.bsky.social 🎉 In the lab we will study how differences in X-linked gene dosage between the sexes affect fetal growth and survival and contribute to sex differences later in life 👩‍🔬🧪🧬🧫

Choanoflagellate transfection just got much cheaper: www.biorxiv.org/content/10.6... Congratulations @frutag33.bsky.social & team. #choanoflagellates #transfection

The best stories are the personal ones. So before we get to the new preprint, stay awhile and listen #MobileLabs #TREC

I was saddened to learn of the passing of Chandler Fulton. I met him a few times & recently served with him on a PhD committee. His work using Naegleria & his energy & enthusiasm will remain an inspiration for exploration-based science and for how to study non-models. RIP Chan. tinyurl.com/CFulton1
