Long in the making, but happy to present the Chlamydomonas chlororibosome! Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins. bioRxiv 📖: shorturl.at/q44tG This suggests greater chlororibosome diversity than expected! 1/n 🧵

🚨 new work from the lab on how eye movements 👀 versus orofacial movements influence 🐭 visual cortex activity 🧠 #neuroscience #behavior #neuroAI

There was so much to unpack with this data, we teamed up with the marvellous @margotriggi.bsky.social to help explain what we think is going on. (Please also check out our model of central apparatus assembly here: www.biorxiv.org/content/10.6...)

This is finally out in J Neuroscience! A micropatterned presynapse-on-glass approach to resolve the nanoscale architecture and function of presynapses www.jneurosci.org/content/earl...

Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila.

Final version is out! Our large-scale cryo-ET dataset 🔬 of Chlamydomonas reinhardtii 🦠 is now published in @cp-molcell.bsky.social Huge collaborative effort! So glad to see the community already using it to develop new resources & tools. Check it out here: shorturl.at/z4i4c #CryoEM #CryoET

New preprint showing how the membrane-associated periodic skeleton (MPS) restricts endocytosis in neurons: www.biorxiv.org/content/10.6... It nicely confirms our work from last year (science.org/doi/10.1126/science.ado2032) and extends it to other compartments in more mature neurons

I am currently reading Innumeracy. We were warned about the dangers of a society incapable of doing basic math 37 years ago. How I wish elected officials, anti-vaxxers and conspiracy theorists would read that book😞.

New release of #BigVolumeBrowser. Many things were added: UI improvement (thanks to @kwolbachia.bsky.social feedback), pyramidization for BioFormats dataset, bug fixes. Now there is an isosurface rendering mode (1/4)

Devcontainers are great. But related, does anybody know of a good mechanism to bleep the secrets that ClaudeCode or OpenCode spill when they decide to ignore deny rules? Like a rule that replaceAll()s everything on the client before it goes out?

I had heard this was coming, but it’s still an amazing indication of how far we’ve come in the last decade or so!

Have you ever wondered what you would find if you could keep your eyes on a bee for more than a few meters? Us, too! preprint (with videos!) + thread 🧵 Precise, individualized foraging flights in honey #bees 🐝 revealed by multicopter drone-based tracking www.biorxiv.org/content/10.6... 1/9

(1/2): Using cryo-electron tomography and an instrument like this one, HHMI Investigator Michael Rosen & team (not pictured) have captured the most detailed images to date of the molecules inside chromatin condensates. hhmi.news/4iFBIrV

Very excited to show off our latest data. Videos hot off the microscope! Come see what crazy things cells of al types are up to tomorrow!

I am very much in favor, we just put out a recent preprint thinking about learning to navigate from the perspective of generative models of trajectories www.biorxiv.org/content/10.1...

The era of coding agents is here. How do we approach this as scientists? Wednesday Dec 10th at 9am PT I'll livestream an interactive demo of what I have learned (matsen.group/agentic.html) about how to leverage agentic coding to do rigorous science. www.youtube.com/watch?v=Rbhs...

Do you have 2D-to-3D image registration challenges? Let me know about them here forum.image.sc/t/toward-bet...

Our new paper showcasing molecular connectomics with pan-expansion microscopy is out in @natbiotech.nature.com! www.nature.com/articles/s41... This wonderful collaboration with @bewersdorflab.bsky.social was led by Ons M'Saad (now founder/CEO of Panluminate) and @allisonphysics.bsky.social. (1/5)

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji. It ships many new features, detailed below, but that are articulated around the following:

Finally, the first public release of #BigVolumeBrowser, so after teasers, you can try it yourself. For details, please check the announcement post (1/2) forum.image.sc/t/bigvolumeb...

Wow, huge work, congratulations to all!

The songbird basal ganglia connectome https://www.biorxiv.org/content/10.1101/2025.10.25.684569v1

A new, nerdy paper. We figured out (some) of the rules underlying cell-permeability of probes and designed ligands that light up, grab, and move proteins around. Awesome @hhmijanelia.bsky.social x @uwmadison.bsky.social x @stjuderesearch.bsky.social collaboration! www.pnas.org/doi/10.1073/...

Hello dear diary, today I've added some minor features, like highlighting boxes and canvas selecting objects + manual transform mode. Small update, mucho trabajo, but it should be helpful for user experience #bigvolumebrowser

The Shanahan Fellowship is a unique PostDoc opportunity at the intersection of Neuroscience and Data Science. If you are considering a PostDoc in this area, I encourage you to apply! Applications are open! And due by Dec 1st alleninstitute.org/shanahan-fou...

Very excited to be co-organizing this meeting. Hope to see you there!

Excited to share our new #biorxivpreprint: “Sexual dimorphism in the complete connectome of the Drosophila male central nervous system” www.biorxiv.org/content/10.1... We describe the #connectomics reconstruction and analysis of an entire adult #maleCNS #drosophila central nervous system. 1/10

The connectome of the entire male Drosophila central nervous system is out!! Acquired using FIB-SEM @ 8x8x8nm, we aligned 7.5 mio 2D images aligned into one seamless 3D volume, which was used to segment & proofread neurons and synapses. @hhmijanelia.bsky.social www.biorxiv.org/content/10.1...

Cell Physics community is missing Jochen Guck deeply.. He was a very kind and generous person, one of the most creative minds, and always ready to help everyone in the field.. He inspired many of us.. He will always be missed..

Great Job - Great Colleagues - Great Science👍 Help us pick the next generation of @hhmi.org Investigators, Freeman Hrabowski Scholars, Hanna Gray Fellows, Gilliam Fellows Relocation to DC is required, perfect for academic PIs looking for their next chapter hhmi.wd1.myworkdayjobs.com/External/job...

I love this piece! It shows the many ways a connectome can be put to use, AND the many complementary modalities that are needed, beyond the connectome, to answer real questions. And it makes me feel good about having helped to generate the thing. :)
