Super excited to have this preprint lead by @jayrshenoy out for people to see! Exciting work!

AlphaFold-based models like Boltz-2 and BioEmu train on atomic conformational structures in order to predict protein dynamics. But is it possible to train these models directly on cryo-EM map ensembles, harnessing conformational data that is typically not deposited in the PDB? Introducing CryoSampler: a new approach for fine-tuning Boltz-2 with raw supervision on cryo-EM map ensembles. 1/6🧵

Super proud of @PolymathicAI 's new foundation model on biomolecules! 🚀 It was probably the most challenging datasets 💪 we have gathered so far (which we are making public!) and realizing biology is super hard even when you work with the best domain scientists @PilarCossio2 @sonyahans @JonesyLab & @OlgaTroyanskaya Hats off to the team led by @SiavashGolkar J.Kovalic @irina_espejo , @samsledzieski & @mhli41 !

Postdoc job opening! This is a unique opportunity to work at the intersection of computation of experiment between us at the Flatiron and a time-resolved cryo-EM lab at the Crick: crick.wd3.myworkdayjobs.com/… Deadline May 6.

If you're not on the multi-thousand-person cryo-EM listservs... we (EZ lab @PrincetonCS, @FlatironInst, #CCPEM) just announced a new #heterogeneity challenge for cryo-EM! #CAHRA2025 Webinar this Fri Nov 14 at 12p ET. Datasets and more info here: heterogeneity.notion.site/ch… We've been preparing this challenge for over a year 🥵 (designing the heterogeneity, collecting data, validating results and metrics). Super excited to finally share it with the community! There are three mystery❓❔❓ datasets! Some fun facts about each: 1) comp-het: an experimental dataset containing a mixture of mystery❔complexes 2) conf-het: we're asking folks to submit *atomic models* instead of density maps for the first time ❗️❕ 3) pose-entanglement: a simple dataset to test how much the pose distribution influences conformation estimation 🐎 Huge shoutout to the members of my group driving this work @FeathersRyan and Robert Heeter, @sonyahans @PilarCossio2's groups @FlatironInst, and Joel Greer from Tom Burnley's group at #CCPEM. Calling both methods developers and users to participate! Check out our website for more details!

Announcing cryo-EM heterogeneity challenge #2, now dubbed the 2025 Community-Wide Assessment of Cryo-EM Heterogeneous Reconstruction Algorithms (CAHRA)! Join us for a webinar next Friday (Nov 14th) to learn more. Datasets already posted here: heterogeneity.notion.site/ch…

Last week, #FlatironCCM and #FlatironCCB held a Computational Cryo-EM Workshop that focused on methods for 3D heterogeneity analysis including deep learning and statistical techniques in cryo-EM. #science #biology #math

Check out our latest preprint for the first community #cryoEM heterogeneity challenge 🎆🎇 @sonyahans @miroastore method developers and participants!

That's a wrap! The results of the first #cryoEM heterogeneity challenge are up on biorxiv! biorxiv.org/content/10.1101/…
