We can't wait Mathilda ! We are very excited for you to start next week.

Today was my last day in Dresden. I am very sad to say good bye to the @nadlerlab.bsky.social and @mpi-cbg.de. I am so grateful for the amazing PhD time I had and all the friends I made along the way. Thanks so so much to André and the whole lab!

If some of you are still wondering why we screen randomly purchased antibodies in ExM? Well, cuz we randomely find antibodies labelling key organelles and structures across many species...

Reese Richardson@reeserichardson.bsky.social · 3d ago

A massive update: At least ~15 companies~ are selling scientists antibodies using faked validation data. We've documented 18,000+ manipulated images on 17,000+ products sold by leading laboratory suppliers including Thermo Fisher, Abcam, Santa Cruz Biotechnology, Millipore Sigma and Bio-Techne. 1/🧵

My new book, Phylogenetic Biology, is now published. Available online for free at dunnlab.org/phylogenetic... . Physical copies can be purchased at shop.lightningsource.com/b/085?params... or your favorite bookstore.

Looking forward. #Paris is always a lovely trip !

📢 Institut Jacques Monod Seminar 📅 September 18th 📍Institut Jacques Monod Invited by the Dumont Lab, Prof. Omaya Dudin ( @dudinlab.bsky.social ) will present an Institut Jacques Monod seminar on the theme "Data-Driven Inference of Cell Migration and Polarity Dynamics" ➡️ buff.ly/yf2VDLI

I'm thrilled to share that I've started as an Assistant Professor in Biological Sciences and the Oceans Research Center at Lehigh University! I'm building a group in evolutionary genomics to study the origin of animals, and to use those concepts to better understand human disease. More: evogeno.me

Thanks @prelights.bsky.social & @girishkalephd.bsky.social & Anne. A nice piece, that motivated us to push through revisions ;).

A stress response can be a great starting point for discovering new biology! By following genes regulated during the chloroplast unfolded protein response, we’re discovering novel factors involved in chloroplast homeostasis. Here’s the first one we characterized: www.pnas.org/doi/10.1073/...

Very pleased to finally share the main story from my PhD, now published in @natcomms.nature.com ! 🎉 Using a sea anemone we discovered and characterised epithelial cell extrusion as the mechanism underlying starvation-induced cell loss. 🔗 Open-access article: www.nature.com/articles/s41...

Epithelial cell extrusion underlies starvation-induced cell loss in a sea anemone - Nature Communications

Epithelial cell extrusion in a sea anemone shares key hallmarks with bilaterians and is dynamically regulated by nutritional status. During starvation-induced body shrinkage, extrusion likely contribu...

We're hiring 4 postdocs at @unibo.it to study nervous system evolution. Seeking expertise in single-cell genomics, molecular or developmental biology in ctenophores, cnidarians, echinoderms, flies or human stem cells. 2+2 yrs contract. Deadline: 26 Aug. Please share! bandi.unibo.it/s/apos7/proc...

If you are interested in nervous system evolution you may want to read our review with Kei Jokura on nerve nets: "Revisiting nerve nets: functional organization and evolutionary implication" https://link.springer.com/article/10.1038/s44318-026-00879-w […] [Original post on biologists.social]

No, these images are not AI-generated, not even photoshopped. They do look artificial because there is something artificial about them: the extra 150 ppm of CO2 resulting from human activity, which has irretrievably transformed the world.

Look who is starting next door ! Super excited to have @helsenjana.bsky.social at less than 3min walk from my lab ! We are starting to have a "small fish but big teeth" Evolutionary Cell Biology hub at @sciencesunige.bsky.social

Jana Helsen@helsenjana.bsky.social · last mo.

I am starting my lab at the University of Geneva next January! Incredibly excited to soon be joining the MOCEL department as an Asst. Professor. The lab will use evolutionary cell biology to study chromosomes, centromeres & speciation 🧬🔬🌱 Intrigued, want to join or collaborate? 🔗 helsenlab.org

Very excited to dive into the diversity of FRESHWATER perkinsids of the Masurian Lakeland together with Anna Karnkwoska - supported by a joint grant from the Polish and Czech grant agencies NCN & GAČR! #perkinsids #freshwater #protistsonsky

Anna Karnkowska@ankarn.bsky.social · 2mo ago

🎉 Excited to share that Elisabeth Hehenberger and I have been awarded a 🇵🇱🇨🇿 NCN–GAČR grant! We'll explore the diversity, ecology, and interactions of Perkinsea, a fascinating and largely overlooked group of parasitic #protists in #freshwaters. Looking forward to this exciting collaboration!

As always @burnsajohn.bsky.social you are too nice ! It was/is a pleasure working with you mate.

John Burns@burnsajohn.bsky.social · 2mo ago

I recently did this interview with NEB covering a lot of the work I've been involved with lately (e.g. @dudinlab.bsky.social) Hopefully there's something interesting in there and nothing too egregious! Some of the work fits #protistsonsky. Enjoy? www.neb.com/en-us/podcas...

Cell-cell junctions are everywhere for whoever wanna find them ! Amazing story. I wonder how many "non-typical" junctions exist outthere !

Gregor Weiss@weiss-lab.bsky.social · 2mo ago

Some bacteria do not live as individuals. They build multicellular filaments and connect neighboring cells through tiny cell-cell junctions. Cyanobacteria are among the most beautiful examples 😍 In our new paper, we reveal first molecuar insights on the cyanobacterial septal junction architecture 🧵

Thanks @luisjagago.bsky.social for all your efforts in making this an awesome trip to the team. We can't wait to start expanding and imaging ;)

Luis Javier Galindo@luisjagago.bsky.social · 2mo ago

In September we will have the pleasure of hosting Karla and @fmikus.bsky.social from the labs of @dudinlab.bsky.social and @gautamdey.bsky.social. If you are around Granada please join us for their talk! They will present ExÂME, an incredible initiative to build a 3D atlas of protists diversity!
