Now in Nature SMB: how do proteins fold while still being made? We solved all-atom structures of two ribosome-tethered folding intermediates—invisible to cryo-EM, seen only by ¹⁹F NMR. Thank you @julianstreit.bsky.social, John Christodoulou & co-authors! nature.com/articles/s41594-026-01814-7

Hats off to JC and team, amazing work

Microscopy nerd alert: two scopes in California can now do phase contrast cryoEM - potentially fixing the tech's very low signal/noise ratio. The phase filter they used is a laser. Which is also the brightest thing in the solar system (outside of the inside of the sun). cen.acs.org/analytical-c...

Scientists detail a previously unknown pathway by which our bodies fight infections--directly inside infected cells. Read more in Molecular Cell: www.cell.com/molecular-ce... Tyler Rhinesmith, Leo James, & colleagues @cp-molcell.bsky.social

Automation of #CryoEM SPA from raw movies in @cryosparc.bsky.social to the generation of high-resolution density maps Resolution improved in 80% of the targeted #GPCR datasets The pipeline in this paper is available for download and use: biorxiv.org/content/10.1...

Incredibly excited and grateful to be joining the Burroughs Wellcome Fund family! Thank you @bwfund.bsky.social and the selection committee members for supporting and believing in our vision and congrats to the other 2026 PATH Investigators!!! 🥳

Exciting to see momentum building around our concept of inverse agonist-bound GPCR–G protein complex structures (PMID: 39775170). Great work from the groups of Can Cao & Xiaoguang Lei: a clinically viable MRGPRX4 inverse agonist for chronic itch with therapeutic potential. Congrats to all!

Effective laser phase plates should be transformational for cryo-EM and this proof of principle study shows a pulsed system successfully intergrated in a SEM. A powerful step towards functional systems in a cryo-TEM

Neuroscientists are always looking for new tools that can bring the brain into sharper focus. For postdoc Daniel Du, that means shooting lasers at state-of-the-art microscopes to take better snapshots of the building blocks of the brain: zuckermaninstitute.columbia.edu/science-life...

How do you make one of the best microscopes in biology even better? Postdoc Daniel Du of the Fitzpatrick lab zapped electrons with a laser. The new research in @elife.bsky.social with Cornell’s Maxson lab promises improved snapshots of the brain: zuckermaninstitute.columbia.edu/making-world...

🚀 CryoSPARC v5.0 BETA is here! We’re excited to deploy another major #CryoSPARC release to help enable and accelerate #cryoEM data analysis. v5 has a redesigned underlying software system and many new features - highlights in thread! Full changelog: cryosparc.com/updates/v5.0.0

Excited to share our latest research, out today in Cell (@cellpress.bsky.social) Using cryo-EM and cell-based studies, we reveal how large nutrient sensing protein complexes form at the lysosomal membrane to turn off mTORC1 and halt anabolic signalling. Read the paper here: doi.org/10.1016/j.ce...

Another member of the Fitzpatrick/Shapiro quad @zuckermanbrain.bsky.social embarks on setting up his lab! If you wish to use #cryoEM #cryoET to study how viruses enter & evade the immune system, & design antibody-based vaccines, check out the Roark lab: isb.med.upenn.edu/research/cryoem-and-cryoet

Organelles do NOT have a single uniform pH. And if you think they must, because “protons diffuse fast,” this paper is for you. A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

A quick tutorial on the DAQ structure validation score for protein models derived from cryo-EM. DAQ evaluates amino acid–level accuracy in your model. Consider including a DAQ validation report in your next publication! www.youtube.com/watch?v=YRAT...

I’m very happy (and grateful!) to share that I’m featured in a Nature Cancer Viewpoint about starting my lab at CNIO. In the Lab (www.rcglab.com) we’re combining AI, protein design and structural biology to study protein structures and design novel protein therapeutics for cancer. 🔬

🔬 Just out in @NatureComms! Using cryo-CLEM and cryo-ET, we reveal the unique ultrastructure of dopaminergic varicosities in the striatum. Amazing collaboration with @davip-bdx.bsky.social and Etienne Herzog @iins-bordeaux.bsky.social Congratulations to Paul and Robin for this fantastic work! 🎉

December Update of DAQ-Score DB! Quality evaluations of protein models from cryo-EM. Now includes evaluation of 258,956 protein chains. Check at daqdb.kiharalab.org It's very easy to compute DAQ for your protein model. Add the validation result in your publication: em.kiharalab.org/algorithm/da...
