What if AI could invent enzymes that nature hasn’t seen? 👩🔬🧑🔬 Introducing 🪩 DISCO: Diffusion for Sequence-structure CO-design 14 rounds of directed evolution and over a year of wet lab work. That's what it took to engineer an enzyme for selective C(sp³)–H insertion, one of the most challenging transformations in organic chemistry. DISCO surpasses this with a single plate. No pre-specified catalytic residues, no template, no theozyme, no inverse folding, just joint diffusion over protein sequence and structure. 📝 Blog: disco-design.github.io 📄 Paper: arxiv.org/abs/2604.05181 💻 Code: github.com/DISCO-design/D…

"Someone has to do the exploration of knowledge just for knowledge's sake." Frances Arnold reminds us that even if knowledge seems useless today, it may become essential tomorrow – often in ways we can’t yet imagine. Arnold joined us at Nobel Prize Dialogue to discuss the usefulness of useless information. Watch the full session: bit.ly/4bRWCmk #IWD2026 #IWD















Frances Arnold (@francesarnold) pioneered the process of directed evolution — mimicking natural selection to create new enzymes that have changed everything from agriculture to laundry. link.podtrac.com/xsi60ev8

Thrilled to share the first paper from our group at UCLA, online today in Science: “Biocatalytic, Asymmetric Radical Hydrogenation of Unactivated Alkenes” @uclachem @ScienceMagazine science.org/doi/10.1126/sc…

The Microsoft Research Undergraduate Internship Program offers 12-week internships in our Redmond, NYC, or New England labs for rising juniors and seniors who are passionate about technology. Apply by October 6: msft.it/6015scgSJ


Amazing talk by @francesarnold at AITHYRA symposium in one of the best possible venues in Vienna!
