We’re hiring! The Department of Physics @sfuphysics.bsky.social at Simon Fraser U (in beautiful and vibrant Vancouver) seeks applications for an Assistant or Associate Professor in Experimental Biophysics, encompassing all scales of life from molecules to ecosystems. @sfuscience.bsky.social

So proud of this work in which we managed to extract valuable information from the intra- and interdomain dynamics of the Tau protein, it indeed looks like there is valuable information to find in protein disorder, if one figures out how to retrieve it !

📢 New preprint: Experiment-guided AlphaFold3 resolves accurate protein ensembles. doi.org/10.1101/2025... AlphaFold3 is incredible, but has crucial limitations: it typically collapses to a single conformation, ignoring the inherent dynamics of proteins. And it can be wrong. Here's a solution. 🧵👇

Thrilled to share that our latest article is now out in final form! A great collaboration with @fraserlab.com and @silviaosuna.bsky.social. Distal mutations enhance catalysis in designed enzymes by facilitating substrate binding and product release www.nature.com/articles/s41...

New IDPSeminars season on deck 🤩 We hope you can join us to learn about some exciting science! More info in the post below👇

📢 New preprint: Aromatic Ring Flips Reveal Reshaping of Protein Dynamics in Crystals and Complexes. We addressed a long-standing question that people debated already in the 1970s - but it still remained open: Do proteins in crystals move as they do in solution? We used ring flips to find out. 1/n

We are thrilled to be part of Project Diffuse, building infrastructure for the dynamic future of structural biology. We are helping to lead the modeling and encoding efforts of this project, including designing infrastructure that allows AI to learn from the full complexity of experimental data.

Hi bluesky scientists! Recently, @stephanieaw.bsky.social @fraserlab.com held a workshop at UCSF to discuss methods for modeling heterogeneity in structural biology (conformationalensembles.github.io).

Very happy that this story found its home at @pnas.org www.pnas.org/doi/10.1073/...

The Tortured Proteins Department Esp. 2 with @fraserlab.bsky.social is out! In addition to bantering about the craziness of the times, we chat about some recent exciting preprints (see links below). open.spotify.com/show/10PHVou...
