To recognise and celebrate @svobodalab.bsky.social's pivotal contribution to Woodstock Bio2 + Night Science, #TCTeAC, I am starting this "What Petr Svoboda did at Woodstock?" thread. If you were there - #contribute and #retweet. "Petr Didn’t Submit an Abstract. #TCTeAC Submitted to Him."

Our study on endothelial mechanics made the news! 🤩 Super nice and clear article on our findings and their implications. www.snexplores.org/article/how-...

it appears your safe back-up post doc project wasn’t so risk free after all, mr. bond

Amazing defense by @alisonkickuth.bsky.social! Congratulations on the beautiful thesis!

Very happy and excited to share our latest work linking actin nematodynamics and endothelial cell mechanics under anisotropic tension, now published in @natphys.nature.com ! rdcu.be/eigWi @ipparis.bsky.social @polytechniqueparis.bsky.social

Looking for a student or postdoc! Want to combine evolutionary analysis + structural modeling with in vitro biochemistry & fluorescence microscopy? Help us uncover new protein-protein interactions — from in silico to in vitro. Join us at @istaresearch.bsky.social 👉 looselab.org 🧬💡🔬🎡

REPOSTING this here just to officially leave "the other place" Our work on the role of endogenous electric fields in guiding collective cell migration during #morphogenesis is out @naturematerials.bsky.social nature.com/articles/s41...

Very happy that our new paper on social distancing during epidemics has just come out in @pnas.org! With @molinajohnj.bsky.social, Ryoichi Yamamoto, and Matthew S. Turner. Understanding Nash epidemics | PNAS www.pnas.org/doi/10.1073/...

In fun news, a video of mine won the UCLA Broad Stem Cell Research Center's Imaging Competition! You can see a muscle cell (a myoblast) fusing into a moving myotube. These myotubes mature to become our muscle fibers. They are beautiful cells! 🤩 www.youtube.com/watch?v=g6xK...

The Image & Optics Facility @ Institute of Science and Technology Austria is expanding it’s image analysis services and has a vacant position for a service oriented *Image Analysis Specialist* with a strong interest for data infrastructure organization🔬🧑‍💻📈 - sharing is much appreciated

Excited about protein biochemistry, fluorescence microscopy, and image analysis? Curious how proteins drive bacterial division or define organelle identity? Join us at ISTA! Apply to the PhD program by Jan 8th: gradschool.ist.ac.at

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

New paper out with the Kicheva group by S. Lehr and D. Bruckner! 🧪 Develops a new 2D neural tube organoid, and models its striking self-organized patterns! Key finding: patterning via 2-phase dynamics of BMP, which acts like a temporal relay balancing sequential fate decisions! bit.ly/3OJti4G

As promised, here a fast acquisition of a migrating cell videoed under a microscopy, look those membrane dynamics @ the leading edge ! Bonus: nuclear deformation once the cell rear snaps. (Fluo nucleus, for the #fluorescencefriday) @focalplane.bsky.social @cellcommlab.bsky.social #CellMigration 🧪🔬

I have moved to 🦋 as well ! Looking forward to reconnecting with old and initiating new science contacts here

Mix two motors of opposite polarity with microtubules and they will partition space ! Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns. #morphogenesis doi.org/10.1073/pnas... (1/n)

🌱🔬The most time-intensive and difficult paper of my PhD is now published in #mSystemsJ! I'm proud of this work and also how much I've grown since I first started this experiment. Read on to learn more about how the functions of bacterial communities impact plant growth and health. 👇

I thought #fluorescencefriday would be a good opportunity for my first post here. Here are some crazy actin dynamics imaged with TIRF

Before I start posting about newer results on this platform, here is a video from our most recent paper -- www.nature.com/articles/s41...

The cell contacts its chloroplast area by up to 40%! Where does all the material go? Smart design! Chlorophyll absorbs a lot - what is crucial is not its volume but is a high 2d-projected area for example a network. Fast contractions are driven via buckling of the network strands into the voids.

💥Beyond happy 💥 Our work is now published in PNAS! www.pnas.org/doi/10.1073/... With Gloria Canales & @mazi1.bsky.social we studied how the single celled alga Pyrocystis lunula 🌙 move their chloroplast in response to strong light. Get ready for some fun mechanics, signals and organelle motion! 🧵

Introductory post on 🦋! We're a research group headed by Prof. Johanna Ivaska interested in understanding how integrins contribute to every step of cancer progression. We're located at the Turku Bioscience Center in Turku, Finland! Find out more about us and our interests here: ivaskalab.utu.fi

We have an inherent intuition for the progression of time. In entropy producing systems the arrow of time should appear clear and a reversed movie feels thereby wrong. Look at these macroscopic active spheres and try to figure out whether the movie has been reversed.(1/6) arxiv.org/abs/2409.16734

Myoblasts flows on nematics tracks!

Introducing "3D Micropatterned Traction Force Microscopy", our new joint work with Pere Roca-Cusach's lab, led by amazing Laura Faure and Manu Gómez. Hope you find it useful!👇 onlinelibrary.wiley.com/doi/full/10....

Another good example of exciting science from the Barcelona team!

It's not a repost if it's a new platform, right? right?? Lattice light sheet movie of actin in mitosis. Blebby.

Moving some content to this platform. "Synchronization in collectively moving inanimate and living active matter" - Combining cell biology with an unconventional toy model, we show that synchronization unifies speeds in a collective. rdcu.be/dl0JF Here is the story: (1/12)

I’m new to Bluesky - and new to bats - my first bat paper! Led by the amazing Aya Goldshtein. We show how they navigate their environment, and provide evidence that they employ an acoustic map! www.science.org/doi/10.1126/...

Polymerizing actin creates fireworks that are a sight to behold. This excitable medium produces polymerizing waves similar to those observed in other context. The parallels I tried to lay out in this perspective piece last year: tinyurl.com/53cbxm4v (LifeAct-GFP in Endothelial Cell)

Hi #SciSky :) So cool that many are moving here now! I study how chloroplasts in plants and algae move from a physics-y point of view: Here's recent work on a dinoflagellate. doi.org/10.1101/2024... I'm interested in dynamical systems, complex fluids, bioluminescence, stochastic processes etc. :)
