Don't miss the spotlight that @hiralshah.bsky.social wrote :D

Our new paper (with @biotay.bsky.social) is out and on the cover story of @currentbiology.bsky.social !!!! Veronika, a Carinthian mountain cow flexibly uses a “multi-purpose tool” to scratch herself. A video and more information will follow in the comments. www.cell.com/current-biol...

Ever wonder why some projects just work and others slowly eat your soul? In this paper by @urialonlab.bsky.social discuss the importance of choosing both interesting and actually doable ideas. Impact matters as well as feasibility!

Exciting preprint from @franbottanelli.bsky.social and @annespang.bsky.social! ARF-1 regulates FERARI-mediated endosomal kiss-and-run recycling by controlling selective cargo loading into vesicles. ARF-1 Coordinates Cargo Sorting at FERARI Endosomal Recycling Hubs www.biorxiv.org/content/10.6...

😍 😍 Amazing

New preprint from the lab 🎉: γ-tubulin is a novel target of the tubulin autoregulation pathway! Previously thought to exclusively target α- and β-tubulin mRNAs, we show that the TTC5–SCAPER–CNOT11 axis also degrades γ-tubulin mRNA, expanding the scope of this fundamental regulatory mechanism.

This is the cover proposal I made for our recent paper! It’s Pyramimonas diskoicola — a very beautiful green flagellate and one of those cells that makes you stop and stare for a while. I tried to capture its shape, symmetry, and general vibe :) #FluorescenceFriday #BioArt #SciArt #Illustration

Nice summary on our paper on mechanisms controlling development and evolution of the cone-dominant ground squirrel retina, which is now in final form at eLife. www.lifescienceeditors.com/2026/01/06/h...

After years of struggling with how to cryopreserve one of our endosymbiotic bacteria, we found something that worked! 🦠☃️ We crowd-sourced suggestions and then @ruthwright.bsky.social tried the most common ones (like 🥛...). Want to do the same? Here is how we did it: www.biorxiv.org/content/10.6...

New paper from the @rouxlab.bsky.social on Nature Communications! We study how membrane tension is spatially organized in cells. Using the mechanosensitive probe Flipper-TR to visualize tension across the plasma membrane of adherent cells and to dissect the conditions needed for a gradient to happen

Just uploaded our new preprint to @ecoevorxiv.bsky.social Multinucleate life really is everywhere...from deep sea forams to slime molds, intracellular parasites, and beyond. 🚀 We explore how scaling, ecology, & evolution intersect when many nuclei share a single cytoplasm. doi.org/10.32942/X2M...

Grants writing tips: (1) Rejections are totally normal, have faith in your idea, push it and improve it; (2) Every panel is different. Study it and prepare your grant for them; (3) Grant-writing takes months. Plan it and get diverse feedback and (4) Have fun with it! The work there is never wasted 😜

In 2023, we first sampled from a geothermal tributary at LVNP and using enrichment culturing, found an amoeba growing at high temp.

The lab’s first pre-print! We investigated how growth-inducing Erk activity waves are regulated in regenerating zebrafish scales. We discovered that Erk waves are followed by waves of expression of their own inhibitors, as predicted by excitable waves theory. tinyurl.com/26r2cmpj
