We’re relaunching The Matter Blotter — our Substack newsletter where the Matter Lab members will be writing about their research in greater detail, going beyond what’s possible on social media (and way past the Bluesky character limit!). Subscribe here: aspuru.substack.com

Our director, @aspuru.bsky.social, has been named alongside Sheila McIlraith as AI2050 Senior Fellows by Schmidt Sciences. The prestigious fellowship honours researchers advancing responsible innovation and the development of AI that benefits humanity. Learn more: uoft.me/bYA

New paper out in PNAS Nexus! Molecules aren’t flat — so why should our models be?🧬 Our latest work "Stereochemistry-aware string-based molecular generation,” explores how considering stereochemistry changes the way machine learning models design molecules. Link: doi.org/10.1093/pnas... [1/4]

What do transition state search, geometry relaxation, zero point energy corrections, and extrema classification have in common? They all require Hessians! The problem is, accurate Hessians are really expensive, even with MLIPs. We say, just shoot 'em from the HIP! 🤠 [1/4]

Excited to share our new article: “Quantum algorithm for vibronic dynamics: case study on singlet fission solar cell design”, now published in Quantum Science and Technology! 📜 Paper: doi.org/10.1088/2058... 📝 Blog post overview: pennylane.ai/blog/2025/02... [1/8]

Our lab director, @aspuru.bsky.social, talking about the University of Toronto: “I am the happiest guy here.” This Nature article shares his story, the experiences of other scientists who made international faculty moves, and advice for those considering such a leap. www.nature.com/articles/d41...

And I just found this related Perspective by @aspuru.bsky.social and Varinia Bernales in Polyhedron where they argue that in #CompChem "we are at a crossroads where artificial intelligence will further democratize our discipline" doi.org/10.1016/j.po...

Ever wondered how to get organic chemists to synthesize the molecules you designed with your newest generative AI model? Please check out our latest article: “The elephant in the lab: Synthesizability in generative small-molecule design”. 🐘 Link to preprint: chemrxiv.org/engage/chemr... [1/4]

With all the recent interest in physical machine learning, @realmantilla.bsky.social and I wondered what would be a mechanical machine learning system? We devised a simple springs and sticks model that leads to very interesting thermodynamics learning limits. #chemsky #physicssky #machinelearning

Excited to share our most recent work: “Learning with springs and sticks” — now on arXiv! Paper link: arxiv.org/abs/2508.19015 Project page (with animations & code): bestquark.github.io/springs-and-... Authors: @realmantilla.bsky.social, @aspuru.bsky.social [1/4]

Have you ever wanted to use computer vision to speed up your materials research, but weren’t sure where to start? High-throughput synthesis can generate huge libraries of new materials. However, characterization often lags behind, becoming the real bottleneck in discovery. [1/6]

A hands-on tutorial on computer vision for chemistry coming out of @thematterlab.bsky.social in collaboration with @omarfarha.bsky.social ‘s lab led by Matter lab’s director of research @variniabernales.bsky.social @accelerationc.bsky.social #chemsky #compchemsky #computervision #selfdrivinglabs

We're excited to present our latest article in Nature Machine Intelligence - Boosting the predictive power of protein representations with a corpus of text annotations. Link: www.nature.com/articles/s42... [1/4]

What if, instead of trying to predict properties of every molecule, we focus on simply ranking them? After all, when running Bayesian optimization (BO) for drug/materials discovery, what matters is picking the best candidates first. Paper: doi.org/10.1063/5.02... Code: github.com/gkwt/rbo [1/5]
