Woohoo, copick is out! Access to massive amounts of CryoET data, MCP for agentic, plus a @napari.org interface!

We even used it when hosting the CZII CryoET Kaggle competition: www.kaggle.com/competitions... when we needed to support a large collaborative annotation event with humans + ML models.

An illustration of an apical region of an animal cell in cross section, shown crowded with individual molecules. The plasma membrane is densely occupied by influenza virus glycoproteins, and from the surface bud influenza virions with different morphologies (L-R): spherical, bacilliform, filamentous with a genome, filamentous and empty, filamentous with a helical inner layer, and filamentous with a cofilactin cytoskeleton.

🚨New pre-print!🚨
Because influenza virions are highly variable in form no single method can show their molecular architecture in detail. Here, we integrate multiple structural and compositional approaches to identify new features of these beautiful virus particles

initial model - class 3d - post-processing

it’s been a while. Since I have no local workstation for data processing in my new role yet, I’ve been playing with AWS.

In my downtime, I asked Claude Code to follow a RELION tutorial from scratch. With a few fixes, I got a 3.22 Å result.

Not bad for AI handling routine tasks! :P

Best 3D reconstruction so far from this Tundra dataset. Right shape with some hints of secondary structure. Data collected at a higher magnification will hopefully improve this. @nusbf.bsky.social #cryoEM

Chatbot-type AI has the same issue the invention of the internet had. The benefit of lots of access to information but then it immediately gets worse because it comes with no ability to filter disinformation. And then over time people game the disinformation aspect of it.

This is a well balanced assessment of AI in science. It's hard to know where the balance is and it's hard to maintain that balance even if you do since it can immediately solve your problem that's due tomorrow at the tiny tiny cost of a smidgen of future skill. But it adds up.

7) Using cryoET and STA we find that aldolase particles stuck at the AWI not only adopt a single orientation, but these particles are also partially denatured at the AWI! Only when aldolase particles were pushed into bulk ice with SurfACT did they remain intact.

Finally got around to porting my coot-trimmings scripts over to Coot 1... only the hotkeys are working (nothing requiring creating a custom menu or GUI dialog), but I've added a couple of new ones, e.g. copy/pasting ligands.

Check it out & let me know what you think! 😊

The indirect — and sometimes surprising — benefits of vaccines Many vaccines confer surprising knock-on, or indirect, health benefits when they have been put into widespread use.

Multiple vaccines offer benefits beyond protecting the vaccinated individual from the disease the vaccine targets. Some protect fetuses in the womb, some protect people who are immunocompromised, some protect seniors. As vax rates fall, these benefits are threatened. www.statnews.com/2026/03/19/v...
