So great to see this work come out from my colleague's lab @cdsnow.bsky.social at CSU. Truly a dream-come-true innovation that will really accelerate X-ray structure determination. Applications are endless. Take a look and see if your protein of interest will work.

Stackreg will do it for you. But you may need to background subtract so it focuses on the thing moving and not on background stuff.

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

It's been a privilege to be involved with this. #FRET approaches have so many potential applications for linking in vitro studies with in cell behaviours, but lacked a consistent benchmarking molecule that works across systems: not any more! #IDRs #smFRET #singlemolecule

Single-molecule dynamics of the TRiC chaperonin system in vivo - Nature Single-particle tracking experiments&nbsp;in intact cells reveal dynamic co- and post-translational interactions of the TRiC–PFD chaperonin complex with client proteins during in vivo protein folding.

I’m excited to share my first-author paper, with co-first author @rongqinxiaoxiao.bsky.social, now out in @nature.com. We developed a live-cell single-particle tracking platform to see how TRiC & prefoldin engage proteins during co- and post-translational folding. 1/9 www.nature.com/articles/s41...

This was a great chance to work with @IwasakiLabRiken to discuss the nearly perfect complementarity of Ribo-Seq and single molecule imaging studies of mRNA translation. I hope there are more studies in the future combining these two modalities to unravel translational regulation.

Developability comes for free...? Did AI de novo antibody generation models learn developability properties without explicitly being trained on this?

Love this theory for why antibody generative models produce sequences with nice developability properties: it’s a reflection of PDB. ayusuf.substack.com/p/developabi....

This is a very nice example of one way of thinking about conditional generative models.
