In case you're missing my poster at #NeurIPS2025 about how I fine-tuned DINOv2 to ophthalmological images, here are some animations so you don't miss out! 🔗 Preprint: doi.org/10.48550/arX... 🔗 Code: github.com/peng-lab/rmlp 🧵1/9

Are you also often frustrated when DINOv2 puts very high attention on background patches, rather than cute fox heads? @virtualhomo.bsky.social found an elegant way to regularize DINOv2 training using randomised linear algebra 🤯 Check out his thread or even his poster if you're at #NeurIPS2025.

I wrote a paper with @lorenzlamm.bsky.social, @marionjasnin.bsky.social, @tingyingpeng.bsky.social, F. Eckardt and B. Schworm and got accepted at #NeurIPS2025 and fun fact: 90% of viewers are enby vegans! 🤟 So if u fit there, u might wanna check it out! Maybe also if you don't. We're allies here <3

I'm pleased to announce 🍦 Icecream 🍨 v0.3! New features include: * Training on multiple tomograms (same training time, with linear increase in RAM) 🚀 * Logging and plotting of the loss function 📉 * The --scale option is now called --eq-weight for clarity 😉 We'd love to hear your feedback! 🙏🏽

You might have noticed lots of activity in the napari project recently! 🚀 We're grateful for a grant from CZI that's keeping us going, but grants don't last forever: we're trying to figure out sustainable long term funding. Read our blog post to find out how you can help: napari.org/island-dispa...

✨Excited that the main project of my PhD is now available as a pre-print on #bioRxiv Here, we used #CryoET to visualise mitochondrial proteostatic stress and together with SPA #CryoEM shed light into the functional cycle of the Hsp60:10 chaperone system. #TeamTomo 🔗 www.biorxiv.org/content/10.1...

Time for a thread!🧵 How different is the molecular organization of thylakoids in “higher” plants🌱? To find out, we teamed up with @profmattjohnson.bsky.social to dive into spinach chloroplasts with #CryoET ❄️🔬. Curious? ..Read on! #TeamTomo #PlantScience 🧪 🧶🧬 🌾 elifesciences.org/articles/105... 1/🧵

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture. buff.ly/j3TSIkn

Better ML for cryo-ET starts with better benchmarks. We built a phantom cryo-ET dataset (~500 tomograms) + hosted a Kaggle challenge. The result: community models beat expert tools. Read more in the @natmethods.nature.com article that just came out: 🔗 doi.org/10.1038/s415...

Proud to share our latest paper. doi.org/10.1016/j.cr... Through the dedication of @glynnca.bsky.social and @cryingem.bsky.social we report a thorough method to image molecular organisation within hippocampus tissue. Structural biology in tissue is well and truly here! @rosfrankinst.bsky.social

Final PhD paper now reviewed and published in JSB:X. I was happy with some great reviews that improved the paper! Thanks to Sander Roet for his help with the code base, and Remco Veltkamp and @fridof.bsky.social

You want to start tomography? Solve structures inside cells? Reach Nyquist 😳 ? @phaips.vd.st and I have a website for you! tomoguide.github.io You'll find a tutorial on how to reconstruct tomograms, pick particles and do subtomogram averaging, using different software! Hope it will be useful !

Hey #TeamTomo, Ever been in need of a tutorial about the fundamentals of cryo-electron tomography? From preprocessing raw frames to high-res subtomogram averaging? That's why @florentwaltz.bsky.social and I made this website! tomoguide.github.io Follow the thread 1 /🧵 #CryoET #CryoEM 🔬🧪

MemBrain v2: an end-to-end tool for the analysis of membranes in cryo-electron tomography [updated] Cryo-ET membrane analysis via deep learning.

We’ve updated our powerful MemBrain-seg tool for CryoET membrane segmentation! Plus, we’re introducing two new tools: MemBrain-pick for particle picking and MemBrain-stats for statistical analysis. Feedback is warmly welcome!

Check out the latest version of MemBrain, spearheaded by computation superstar @lorenzlamm.bsky.social ! It can segment, pick particles and give you metrics on everything!

🦠🧠 MemBrain update! 🧠🦠 We’ve updated our preprint! It now covers the full MemBrain v2 pipeline for end-to-end membrane analysis in #CryoET: segmentation, particle picking, and spatial statistics. 🔗 Preprint: doi.org/10.1101/2024... 🔗 Code: github.com/CellArchLab/... 🧵(1/6) #TeamTomo

Yo #TeamTomo, check out our updated #MemBrain v2 preprint. And better yet, give it a whirl on your #CryoET membranes! Please send us your feedback! 🧪🧶🧬🔬

We have updated our #MemBrain v2 preprint with a lot more details about the MemBrain-pick and MemBrain-stats modules, as well as some application examples! Stay tuned for the upcoming thread by lead author @lorenzlamm.bsky.social! 🧠🧵 #CryoET #TeamTomo www.biorxiv.org/content/10.1...

I've got bad news for #teamtomo: earlier today, our resident headcrab attacked @lorenzlamm.bsky.social, turning his Mem🧠 into 🧟‍♂️🧠

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!🧪🧶🧬🌾

The final version of our work on the in-cell architecture of the mitochondrial respiratory chain is now online in @science.org 🎉 You can find the full story here www.science.org/doi/10.1126/... @verenaresch.bsky.social did a wonderful job on the cover and animation, she really brought it to life 👩‍🎨

Hey #teamtomo, if you often find yourself using the excellent membrain-seg from @lorenzlamm.bsky.social et al., you might find my napari plugin "napari-segselect" useful. Let's say your tomogram contains the edges of two bacterial cells, each with a membrane and cell wall:

Exciting update on the CryoET Data Portal! A new annotation set from Mart Last & team is now live. They’ve doubled available annotations with >1,800 tomograms of Chlamydomonas reinhardtii which now have almost fully dense labels, and all can be visualized in the browser using Neuroglancer.

In case you missed our first webinar of 2025, it is now available. Lorenz Lamm from MUDS - Munich School for Data Science presented MemBrainv2- an end-to-end tool for the analysis of membranes in cryo-electron tomography. https://buff.ly/4hutFwf #SBGridwebinars #ScienceMatters

Looking forward to talking about MemBrain-seg tomorrow and giving a sneak peek into other MemBrain v2 functionalities 👀🚀
