Our story on Srs2/PARI family DNA helicases linking chromatin bridges to the Aurora-B dependent NoCut checkpoint is now out in its peer-reviewed version. Thanks to @reviewcommons.org and @jcb.org for a smooth review process! Original preprint thread here: bsky.app/profile/long...

We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

Our lab is actively looking for PhD students and there is NOW an Open Call for PhD fellowship at the IRB Barcelona!!!!! phd.irbbarcelona.org

An Asgard archaeon with internal membrane compartments Brilliant study led by @fmacleod.bsky.social and Andriko von Kügelgen. Tight collaboration with @buzzbaum.bsky.social and lab. Congrats to all authors! www.biorxiv.org/content/10.1...

🌊 A pandemic-era breakthrough has allowed scientists to literally expand our view of plankton. By using ultrastructure expansion microscopy, researchers visualised the inner workings of hundreds of marine species for the first time www.sciencedaily.com/releases/202...

Success. Nearly 259 Foldscope deployed in hands of unsuspecting candy crazy kids. Halloween is always more colorful with the microscopes - specially in a few weeks they could look at the micro-fauna of the teeth with so much sugar consumption.

🚨Our collaboration with @centriolelab.bsky.social & @gautamdey.bsky.social is out today in @cp-cell.bsky.social We show that #Expansion #Microscopy is a broad-spectrum modality for Euks, enabling 3D phenotypic maps rooted to phylogeny. #ProtistsOnSky #SciComm #SciSky www.cell.com/cell/fulltex...

Thanks @maxjtelford.bsky.social for this nice write-up of our Hippo signaling paper

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!

Spread the word! There is a professor position opening at our University @upcite.bsky.social. There are several possible (great) labs to join, but if you are interested in DNA methylation and epigenetics in mammals, don't hesitate to contact me directly!

Our ultimate goal: exploring biology beyond well established research organisms, by building tools that will make new things visible Ending 🧵 with a marker for visualising chanoflagellates, closest unicellular relatives of animals, by @jujumathieu.bsky.social and @thibautbrunet.bsky.social

First neurons didn’t appear overnight. We trace their roots to ancient secretory cells - showing how lifestyle & behavior shaped the evolution of first synapses.🧠🌊 #Evolution #Neuroscience Our latest in @natrevneuro.nature.com Link: rdcu.be/eMX3E @jeffcolgren.bsky.social @msarscentre.bsky.social

I am very excited to announce the opening of the submission site for the upcoming Conférences Jacques Monod on Developmental Biology, May 18-22, 2026 cjm.sb-roscoff.fr/en/conferenc... @lionlchristiaen.bsky.social and I have an exciting program of speakers and slots for selected short talks, etc.

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵 Check our latest preprint

Starting Monday!!! If you are in Paris, feel free to drop in for this exceptional course!

Back from fly lab retreat with some little friends :) hope i manage to make them grow in @thibautbrunet.bsky.social’s lab

Sampling from Groix, a new beauty. Veliger larva (thanks @thibautbrunet.bsky.social for identifying this creature!). Probably a mussle.

piRNAs are essential for transposon silencing in the animal germline. But how do hosts trap transposon sequences in genomic loci that help establish a piRNA response? Looking at a natural transposon invasion, Baptiste Rafanel and Kirsten Senti made some remarkable observations.
