Highlights from this week

Preprint—not peer reviewed

uMOF: A Universal Database, Benchmark, and Machine Learning Interatomic Potentials for Metal-Organic Frameworks

The authors release uMOF, combining a density functional theory dataset, a literature-mined benchmark, and universal metal-organic framework potentials. They report that uMOF models outperform tested baselines for dynamics-sensitive adsorption properties and reduce error by more than 80% to within experimental uncertainty. The package links broad physically diverse training data to experimental benchmarks for transferable metal-organic framework simulation.

Mechanistic Reaction Prediction via Discrete Flow Matching on Graph-Structured Electron Occupation

The authors formulate reaction prediction as discrete flow matching over graph-structured electron occupation vectors in a continuous-time Markov chain. On USPTO-480K and the stated out-of-distribution settings, they report competitive prediction, retained performance, mechanism-like trajectories, and side-product prediction. Electron redistribution offers a mechanistically legible alternative to product generation and direct graph edits.

Cartesian tensor equivariant machine-learning force field for spin-dependent atomistic simulations

The authors build HotPP-Spin with Cartesian tensor equivariant message passing and explicit axial-vector magnetic moments. For H-phase monolayer VSe2, they report a finite-size ordering crossover at 415--435 K, close to the reported experimental value. This provides one representation for connecting first-principles magnetic energetics to coupled spin and structural simulations.

A Generalized Approach for Incorporating Geometry and Directionality into Coarse-Grained Machine-Learned Potentials

The authors add molecular geometry and directionality to coarse-grained potentials through anisotropic descriptors and symmetry-adapted message passing. Using Gay-Berne particles and benzene, formamide, and water representations, they report improved energy, force, and torque prediction. The work identifies retained symmetry and geometry as part of the information budget in coarse-grained models.

AdaptNTK: Adaptive Uncertainty Quantification and Active Learning for Neural Network Potentials

The authors introduce AdaptNTK, which measures uncertainty as a regularized Mahalanobis distance in empirical neural tangent kernel feature space. On held-out rMD17 data, they report force-error correlations of 0.68 and 0.71 and a 2.6-fold speedup per Transition-1X cycle. Sequential uncertainty updates offer a route to less redundant acquisition without retraining after each selection.

Accelerating dynamic simulations of photoexcited materials and their evolution by electron-informed machine learning

The authors develop excited-state machine-learning molecular dynamics calibrated against real-time time-dependent density functional theory benchmarks. They report that large-scale simulations resolve phonon competition in bismuth phase transition and structural rearrangement in selenium photoamorphization. This extends learned dynamics toward complex photoexcited materials where electron-nuclear evolution matters.

Hyper-Fold: Exploring the Expressive Limit of Sequence-Geometry Learning for Proteins via Hypergraph Modeling

The authors introduce Hyper-Fold, a rank-K separable convolutional backbone that organizes each radius neighborhood into sequence and contact hyperedges. Across enzyme function, fold classification, and binding-site tasks, they report leading protein-encoder results and lower parameter count and latency for Hyper-Fold-Pocket. The work argues that expressive content-geometry interactions can recover information often attributed to large evolutionary pretraining.

Fourier Neural Operators for Composition-Driven Crystal Structure Discovery

The authors introduce a Fourier Neural Operator crystal-field solver that maps chemical formulae and lattice parameters to periodic density fields. They report novel structures across 104 chemical formulae with competitive reconstruction accuracy, generative diversity, and structural validity. This couples composition-conditioned generation to a reconstruction and screening path for crystal discovery.

Data-driven Effective Modeling of Stochastic Chemical Reaction Networks

The authors approximate the finite-time transition kernel of a stochastic reaction-network Markov chain with a conditional normalizing flow. Their numerical examples report statistically consistent coarse-step trajectories with reduced computational cost. A learned stochastic propagator can decouple useful simulation steps from microscopic reaction-event resolution.

Interpretable physics-informed retrieval-augmented generation language model for end-to-end inorganic crystal synthesis planning

The authors develop PIRAG-LM, which retrieves synthesis precedents by chemical, structural, and thermodynamic similarity before structured route reasoning. They report 91.4% synthesis-method prediction accuracy, compared with 72.1% for the language model alone, and experimental synthesis of five new compounds. Retrieval gives the planning system an interpretable path from materials discovery to experimental realization.

Compiling Chemical Knowledge into Executable Descriptors for Materials Prediction

The authors introduce CRISP, which samples chemical rules, consolidates them, and compiles each into an executable scalar descriptor for a conventional learner. For inorganic-crystal synthesizability, they report stronger results than expert-curated and generic representations under a shared learner, especially under structural-size and chemical-family shifts. The method makes chemical heuristics auditable computational features without relying on structures, labels, or data splits during rule construction.

Language-Informed Flow Matching for Trend-Guided Structure-Based 3D Molecular Generation

The authors use a language-informed flow-matching framework in which target-aware SMILES supply semantic priors to geometric molecular generation. On Cross-Docked2020, they report competitive distribution matching with improved medicinal chemistry metrics and competitive structural validity under task steering. The approach tests whether language-derived chemical context can guide three-dimensional design without further generator fine-tuning.

S3C-LLM: Skill-Code Guided Agentic Language Models for Spectrum-to-Structure Elucidation

The authors introduce S3C-LLM, which retrieves spectroscopy skills, runs analysis code, and integrates peak-level evidence before generating SMILES. Across diverse benchmarks, they report that S3C-LLM outperforms general and spectrum-specific models while using less than 1/10th of SpectraLLM training data. The workflow places analytical constraints inside spectrum-to-structure prediction rather than treating it as direct generation.

RegimeFormer: A Large Protein Model of Global Perturbation Regimes

The authors couple RegimeFormer with RegimeAtlas to model protein perturbation regimes across a harmonized global sequence collection. Across deep mutational scanning and molecular benchmarks, they report reproducible regimes and improved substitution-specific prediction under unseen-protein, unseen-family, and low-homology evaluation. The framework offers a scalable way to map and query mutation response across protein sequence space.

Accelerating Chemical Kinetics for Exoplanet Atmospheres using Neural Networks

The authors develop a residual flow-map neural solver for local-box chemical kinetics in exoplanet atmospheres. They report microsecond-scale inference, percent-level accuracy, and robustness under the extreme stiffness of atmospheric chemistry. A fast surrogate could let atmospheric models retain kinetic effects that equilibrium approximations miss.

SymFold: Synergizing Evolutionary and Structural Priors for Accurate Protein Inverse Folding

The authors use a symmetric dual-path architecture that iteratively combines protein language and multimodal protein language knowledge for sequence generation. Across standard inverse-folding benchmarks, they report state-of-the-art performance and ablations supporting the symmetric design. The design directly addresses the limits of post-hoc sequence refinement in inverse folding.

Text-guided flow matching enables sample-efficient crystal structure generation

The authors introduce TFMat, which conditions a CrystalFlow generator on structured materials language as a semantic prior. Across the stated crystal benchmarks, they report a 92.04% MP-20 match rate with 20 candidates and improved alignment in de novo generation. The result makes materials language an inspectable control layer before downstream simulation and validation.

GRAS: Guided Reduced-Variance Proposals and Adaptive Selection for Training-Free Reward Alignment in Discrete Diffusion

The authors introduce GRAS, which lowers guided-proposal variance and uses an adaptive resampling temperature for training-free discrete diffusion steering. Across regulatory DNA and protein design, they report the best training-free reward and performance that matches or exceeds a reward-fine-tuned model. The analysis isolates a compact change to inference-time search that remains effective for non-differentiable rewards.

Learning Interpretable Tumor Microenvironment Representations by Fitting Pan-Cancer Cell State-Niche Correlation

The authors introduce GITIII-scale, a hierarchical interpretable spatial transcriptomics model that decomposes cell state-niche associations and ligand-receptor pathways. On cancer types unseen in training, they report embeddings that recover niche-associated state changes more accurately than existing spatial transcriptomics foundation models. The model ties pan-cancer representation learning to biological mechanisms that can be inspected for drug-target hypotheses.

Ab initio Modeling of MoS2/Oxide Device Interfaces with Machine Learned Electronic Structures

The authors integrate machine-learned electronic structures with a quantum transport solver for semiconductor device simulation. They report 10,000X speedups over density functional theory for devices above 20,000 atoms and identify an effect of undercoordinated Hf or Al atoms on MoS2 current. Explicit oxide layers can therefore enter transport calculations at device-relevant scales.
