A molecular-resolution look into the near-native architecture of the spinach chloroplast🌱. This one was a long time in the oven, but we're happy to finally share our "version of record". What long-standing debates did we settle? Check back for a short thread🧵 on Monday. #TeamTomo #PlantScience 🧪🧶🧬🔬🌾

Our new paper is out in @currentbiology.bsky.social! Using 3D reconstructions and volume measurements in Drosophila wing primordia, we show that growth can be uncoupled from cell proliferation and uncover a new time window for growth arrest.

Very proud to share our latest preprint: postdoc/LRSF fellow Yue Rui studies the mechanisms regulating attachment of the cell wall to the plasma membrane. The Cellulose Synthase Complex and REMORINs determine the extent of attachment and root osmotic stress tolerance. www.biorxiv.org/content/10.1...

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

One protein, two opposing roles: This ‘compelling’ study shows how the same signalling molecule can drive either protrusion or retraction in migrating cells depending on its concentration and activation dynamics. elifesciences.org/articles/931...

Belyantseva and Liu et al. report that taperin encircles and stabilizes F-#actin at auditory hair cell #stereocilia bases and bundles F-actin. Taperin deficiency causes stereocilia disassembly, rootlet breakage at pivots, and other abnormalities culminating in deafness. rupress.org/jcb/article/...

Incredible 4Pi and pan-expansion imaging of the Golgi 👇

We're on the cover of @science.org this week. Awesome work by @florentwaltz.bsky.social. #CryoET is reaching crazy resolutions inside cells, and this is just the beginning. Fantastic interpretation of the proton motive force by @verenaresch.bsky.social. Always a pleasure making #SciArt with you!🧪🧶🧬🌾

Can you spot the difference? 🔬 SiR-actin labeling can be cytotoxic and affects actin dynamics - while the new XActin probes do not! Developed by @veselin-nasufovic.bsky.social and perfect for time-resolved and STED imaging without the need for genetic manipulation. www.biorxiv.org/content/10.1...

First Post! Thrilled to share our lab's first evolutionary cytoskeleton study! We uncover two distinct FtsZ paralogs in Odinarchaeota OdinFtsZ1 forms curved filaments, while OdinFtsZ2 assembles into spiral rings. A glimpse into tubulin evolution! threads👇 #Eukaryogenesis #AsgardArchaea #cytoskeleton

Huge congrats to Nadja Milivojev @vbcscitraining.bsky.social who successfully defended her @univie.ac.at PhD thesis with a brilliant presentation today. Thanks to examiners Elly Tanaka, Michael @mikebok.bsky.social and Roger Revilla, and both labs for wonderful support!

It’s incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density, which usually isn’t attainable. Lipid-CLEM brought to you by @mathilda95.bsky.social changes that. www.biorxiv.org/content/10.1...

Cicadas have little, bendy micro-pillars on their wings that pierce bacterial membranes and are as effective at killing microbes as a bleach solution. It might be possible to mimic this effect for use in medical (etc.) equipment. 🪳🪲🧪 www.science.org/content/arti...

Kudos to @beingkyo.bsky.social for great supervision, many thanks to Stephanie Ellis and Roger Revilla for joining the panel, and the entire lab for support and presents. Well done Muriel!

Mitochondria- and ER-associated actin are required for mitochondrial fusion - Nature Communications congrats @manorlaboratory.bsky.social & CO www.nature.com/articles/s41...

This #EM_Monday highlights how organelles can shape cells in 🧠! E.g. glia, with their thin processes, often wrap around neurons. But when organelles like lipid droplets (LDs) are present, they can create dents in neighboring neurons—like the one shown here, where a glial LD indents neurons' somas🧵

Mitochondria consist of networks of cylindrical tubes, right? Not necessarily! - in our new preprint, @gavsturm.bsky.social investigates how mitochondria transiently adopt a beads-on-a-string morphology www.biorxiv.org/content/10.1...

Did you know #diatoms are motile? These tiny glass cells have no cilia or flagella and a rigid body yet can glide on surfaces using a specialised slit in the cell wall called the raphe! What is the functional morphology of the raphe? All revealed in our new preprint www.biorxiv.org/content/10.1...

Where does pattern come from inside cells? in this revised preprint, @aralbright.bsky.social Shows that regionalization of mRNA in a Stentor cell depends on dynein motors and the microtubule cytoskeleton doi.org/10.1101/2023...

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)
