Check this one out! Outstanding review to understand all the different approaches that are being used to understand the structure and function of the Cilia and the centriole :) #cytoskeleton #cellbiology PS: and congrats for the cover🥰

Just posted, "The Tiling Tree Method, Part 2: Common Pitfalls and How to Overcome Them" a follow-up to our previous essay on the "tiling tree" method for thinking of all the possible solutions to a problem, by Claire Wang, Nina Khera, and myself. engineeringx.substack.com/p/the-tiling...

This is a glimpse of the cytoskeletal structures we found doing U-ExM in more than 200 species, now in Cell🤩: shorturl.at/6oHvi Amazing collaboration between @centriolelab.bsky.social , @dudinlab.bsky.social and @gautamdey.bsky.social labs. I believe last one is a 🕷️ #FluorescenceFriday #Microscopy

🚨 Come join us @sheffielduni.bsky.social for a PhD on the evolution and development of feathers and flight! 🐣🔬 This project is supervised by @matt-towers.bsky.social & @alexgfletcher.bsky.social, and I'm excited to be involved as a project advisor. Please share! www.findaphd.com/phds/project... 🧪

The A–C linker structure!!! 🤩 Beautiful work. Even if you’re not as centriole-obsessed as we are, you’ll appreciate the elegance and complexity. Amazing to see U-ExM proteins in human centrioles fitting right into these densities. Congrats to all!

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards… What would you do with this? Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵

🚨 We’re hiring a postdoc! 🚨 Interested in lysosomes, Parkinson’s disease, cell biology, microscopy — or all of the above? Come work with us at the Bonet-Ponce Lab! Reach out directly: [email protected] Learn more: bonetponcelab.com Let’s chat!

I found these immune cells just finished mitosis but their midbody is still yet to be resolved. How cool? If you zoom in to the midbody, you can see its classical shape just like in the textbooks. I love these little details.

Stoked to share TWO preprints on mitochondrial pearling! 🎉 We uncover how spontaneous #mitochondria pearling drives #mtDNA nucleoid distribution (doi.org/10.1101/2024...), and @gavsturm.bsky.social et al. dissect the biophysics behind it (doi.org/10.1101/2024...). Details below! 🔬🧵🧪


1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

Heading to HD! Despite my sleepy face I can promise that Im very excited to join the Seeing is Believing 2025 @events.embl.org If you are interested in centrosomes, centrioles, expansion microscopy or protist, don't be shy and let's have a chat! ☺️🤗 #EMBLSymposium #microscopy

UNIGE postdoc? 🎓 Interested in sharing your research in a friendly seminar? Join the new SCIENCE CLUB with Physics, Chemistry & Biology colleagues! Contact us for details 👍 Not a postdoc? Please share with yours!

Really nice contribution of @arcadiascience.com of open high quality drawings across the tree of life. Take a look! research.arcadiascience.com/pub/resource... 😍😍

Now out on bioRxiv. 🥳My research on #cytokinesis, averaging thousands of #ExM images🔬, creating a dynamic atlas of cytokinesis 🦠⏳. Here's an animated sneak peek of what we found. Better resolution on bioRxiv😄 #PSFoftheGIF

#GEF25 the expansion microscopy community would benefit from high NA, long working distance water objectives. Who's working on these? What's out there?

Be our new colleague! 🎉 The Dept of Molecular and Cellular Biology at the University of Geneva is hiring an Assistant Professor or Associate Professor. 👉 More details here: lnkd.in/e8Z9eAm4 👉 Our department: mocel.unige.ch Please feel free to share this opportunity with your network.

Finally 🥂

Our latest preprint on the role of the Arp2/3 complex in mitotic entry is now available @biorxiv. This work was done by Dhanya Kalathil, a very talented postdoc in my lab. The story started in 2019 when we were investigating the role of branched actin in cytokinesis. 1/

Lately I've been only posting images of really interesting protist here, but something that many don't know is that most of my time i'm expanding 'boring' mammalian cells and that I love human centrioles. Don't tell me that they are not beautiful😍👁️ #FluorescenceFriday #CellBiology #Cytoskeleton

It’s truly inspiring to see how persistence, collaboration, and communication across disciplines can transform ambitious ideas into such impactful stories. Seven years, four interdisciplinary teams, and countless discussions later—this really shows the power of timing, teamwork, and shared vision!😍

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins www.biorxiv.org/content/10.1...

🔎New preprint! We reveal a physiological role for tubulin autoregulation, fine-tuning microtubule dynamics and preserving 3D cellular architecture. Big thanks to @ivanagasic.bsky.social and team! Link below for all #cytoskeleton & #spheroid enthusiasts👇(1/5) www.biorxiv.org/content/10.1...

📢 Excited to share our new study in Nature Communications! We show that the A-C linker safeguards centriole architecture & controls duplication. A big congratulations to Lorène for this beautiful discovery, which represents 4 years of her thesis work. www.nature.com/articles/s41...

Thrilled to share our newly published work in @natcellbio.nature.com. We found that differentiating cells tune the size and architecture of mitotic organelles through changes in cytoplasmic density. Many thanks to my fantastic co-authors! 💥

Measuring properties of individual cells in relation to their neighbors in 3D tissues is challenging. @cellysally.bsky.social &co develop a computational toolkit to facilitate this, analyzing developmental patterning in mouse, chick & #Drosophila #embryo @plosbiology.org 🧪 plos.io/4lQMeNu

Excited about this new role! I have admired CRG for long, its amazing science, and how it constantly innovates in how research is done and how it connects with society. Happy to follow Luis Serrano´s work with this incredible community + the ecosystem it is part of & push the boundaries together!

After 5 amazing years @pilhoferlab.bsky.social I'm starting my lab @embl.org Grenoble this November embl.org/wollweber We'll image Asgard archaea and many other strange microbes ( #archaeasky, #protistsonsky..) to understand eukaryogenesis First job ad: #teamtomo scientist!🔬❄️ tinyurl.com/2rdu2ze6

I think I found a very big myosin in the wild! :)🌱

An amoeba with teeth. When building its shell, Netzelia corona selects sharp grains of quartz and positions them around its aperture with the tips pointing inward. I took a few closeups, yesterday. #ProtistsonSky #amoebae #peatlands #MEvoSky

Is there anything more unsettling and beautiful than the eyelids of a red eyed tree frog? They're so ornate and bizarre. I can't think of anything else like them.

Every spike in this photo is a single crystal💠 — an ordered atomic array grown layer by layer. These crystals of transition metal chalcogenide halide doesn’t occur naturally; we built it atom by atom⚛️. Single crystals, which are always chemically pure, allow us to characterise physical properties

Hi Bluesky 😀 Looking for advices on *how to improve my Filipin staining*. The tissue is only 3 cell layers tick. My goal is to stain the PM. If I do it live, cells dies. If I do it fixed (no permeabilization at all to keep the PM intact) it is too weak to makes conclusions. Any advices? Thanks!!
