doi.orgDiscovery of Nanomolar CDK2 Inhibitors Using Boltz-2 | ChemRxivThe computational design of small-molecule ligands for pharmaceutical targets has historically been hindered by a strict trade-off between screening throughput and predictive accuracy. While next-gene...

What does a cofolding model do with chemistry it has never seen? We answer this in our new preprint: A prospective CDK2 inhibitor discovery campaign guided by Boltz-2. Preprint: doi.org/10.26434/che... Code: github.com/papidocha/CD... Data: doi.org/10.5281/zeno...

• 12 of 18 compounds from the first synthesis round inhibited CDK2 at or below 10 µM • Nanomolar inhibitors after a single structure-guided optimization cycle

• A chemotype distinct from all 10,402 known CDK inhibitors in ChEMBL • Boltz-2 outperformed a docking baseline across all 57 synthesized compounds Congratulations to Sven Papidocha, Yoshihiro Ogura, Jiahe Ren, Mikhail Saykin, Stuart Green, @variniabernales.bsky.social, and @aspuru.bsky.social!

Instead of screening a supplier catalogue, the team built a virtual library of 74,000 compounds, none of them for sale, all reachable in a single synthetic step. Boltz-2 then navigated that space prospectively, and the resulting predictions were translated directly into a synthesis plan.

🎉We’re excited to see El Agente Cuántico featured in ScienceNews.dk, highlighting work from The Matter Lab at the University of Toronto, led by our Co-Director @variniabernales.bsky.social, with our interdisciplinary team. ➡️ sciencenews.dk/da/ai-system...

🦾Six specialist AI agents, coordinated by a central agent, support tasks ranging from quantum circuits to energy transport in photosynthetic systems. The goal is to make advanced simulations more accessible and give researchers more time to develop ideas and evaluate results.

🔑 As Varinia mentioned, successful automation still requires careful validation and human oversight. Looking ahead, the team aims to connect simulations with laboratory experiments, bringing computation and experiment into a shared research cycle. Thank you to ScienceNews for featuring our work!

🚀Quantum simulation often requires researchers to navigate complex software, learn different programming interfaces, and troubleshoot calculations.

El Agente Cuántico helps lower these barriers: researchers describe their scientific question, and the system selects computational tools, writes and runs code, and corrects errors along the way.

🤔 What if AI could not only automate scientific experiments, but also design and build the laboratories needed to perform them? We are excited to introduce Self-Building Labs (SBL), a new paradigm for autonomous scientific laboratories! 🌐 self-building-labs.github.io 📜 arxiv.org/abs/2610.23826

Our vision is to move beyond laboratories that simply execute predefined experiments toward scientific infrastructure that can build new capabilities from scratch, continuously adapt, and evolve alongside scientific discovery. We also envision leveraging SBL to build safer laboratories.

👏 This work was co-led by @jiarubai.bsky.social and @allanzhao.bsky.social, along with Han Hao, Miroslav Bogdanovic, Yang Cao, @variniabernales.bsky.social, and @aspuru.bsky.social. Huge congratulations to the entire team for this collaborative effort!

In our latest work, we demonstrate how SBL can: 🔹 Automatically reconstruct digital twins of laboratory equipment and environments. 🔹 Develop and validate new robotic manipulation skills through simulation and physical feedback.

🔹 Execute real-world quantum-dot synthesis experiments, coordinating liquid handling, robotic manipulation, plate sealing, and optical measurements. 🔹 Scale from individual robotic workstations to interconnected laboratories with multiple robots and instruments.

🚀 Self-Building Labs (SBLs) takes a step further: enabling laboratories to autonomously design, configure, and operate based on high-level scientific goals.

Whether starting from an empty laboratory or an existing self-driving lab, SBL aims to autonomously develop the capabilities needed to achieve scientific objectives, from laboratory layouts and digital twins to robotic skills and experimental workflows.

While self-driving laboratories (SDLs) have significantly advanced scientific automation, their capabilities are often limited by predefined equipment, robotic skills, and experimental workflows.

🚀 New work from the group- DIA: Denoising Intermediate Advantage for Diffusion Policy Optimization Paper: arxiv.org/pdf/2609.12245 Blog: github.com/dia-rl/dia Code: dia-rl.github.io

🚀 We also find that DIA can reach successful states more efficiently and move further from the pretrained behavior distribution, highlighting the importance of assigning credit to the intermediate decisions that construct an action.

Kudos to the authors: Arjun Sohal, @allanzhao.bsky.social, Miroslav Bogdanovic and @aspuru.bsky.social 🎉

🚀 New work from the group- DIA: Denoising Intermediate Advantage for Diffusion Policy Optimization Paper: arxiv.org/pdf/2609.12245 Blog: github.com/dia-rl/dia Code: dia-rl.github.io

These inner-loop learning signals are combined with the standard environment-level PPO advantage, giving the policy more informative feedback during optimization.

🔥 Across benchmarks, DIA improves over state-of-the-art diffusion-policy fine-tuning methods for both state- and image-based policies.

🚀 New work from the group- DIA: Denoising Intermediate Advantage for Diffusion Policy Optimization Paper: arxiv.org/pdf/2609.12245 Blog: github.com/dia-rl/dia Code: dia-rl.github.io

🔑 Key insights: DIA introduces credit assignment within the denoising process itself. We showed that better credit assignment inside the generative process can lead to better policy optimization.

The method learns a value function over partially denoised actions and uses it to construct intermediate advantages for individual denoising decisions.

🚀 New work from the group- DIA: Denoising Intermediate Advantage for Diffusion Policy Optimization Paper: arxiv.org/pdf/2609.12245 Blog: github.com/dia-rl/dia Code: dia-rl.github.io

🤔 Diffusion policies generate actions through multiple denoising steps, but standard RL fine-tuning methods often assign the same environment-level credit across the full denoising trajectory.
