Spark-0: Scaling Spatially Aligned Tactile Pretraining for Robot Dexterous Manipulation
A thousand hours of glove touch, used as pretraining signal and as a policy input, lifts dexterous success even when the robot later runs vision-only.

Grounding Generative Verification in 3D Content
A 10-task 3D verification benchmark finds a 21.6-point human–model gap — and shows oracle picking of generated candidates can jump factual success from 26.7% t…

OmniVerifier-C1: Decomposed Graded Verifier for Rule-Governed Generative World Modeling
A pointwise graded visual verifier beats binary True/False critics — and the authors argue pairwise grades are what world-modeling agents actually need.

Discovering state-of-the-art quantum circuits with large language models
An LLM proposes quantum circuits, an independent scorer keeps or kills them — beating published Toffoli and qubit counts on seven of eight tasks.

Sim-to-Real Reinforcement Learning for Path-Safe Target Reaching in Robotic Harvesting of Hydroponic Lettuce
A path-safe PPO trained only in simulation hits 94.7% of physical reaching targets on a UR10e and harvests 86.1% of greenhouse lettuce tries.

Mem4Act: Learning Effective Latent Memory for Long-Horizon Robotic Manipulation
A fixed-size latent memory, trained to be used rather than ignored, posts 81.5% success on four real long-horizon manipulation tasks.

LIBERO-PeRM: Benchmarking Personalized Robotic Manipulation
A 312-task LIBERO fork shows today’s vision-language-action robots barely follow household preferences zero-shot — and still stumble on conflicts after fine-tu…

Perceive, Predict, and Plan: a Unified World Action Model for Egocentric Dexterous Manipulation
One video-diffusion world-action model reconstructs hands, dreams action-conditioned futures, and plans dexterous videos — beating single-mode training on all…

Which Tokens to Merge? Diffusion Dynamics for Efficient Image Generation
Merge diffusion tokens using the denoising trajectory itself — not the prompt — so backgrounds and unmentioned details survive the speedup.

Interlocked Vortex Order in the Frustrated $A_3$V$_9$Te$_{13}$ Lattice ($A$=Cs,Rb)
First-principles work finds a locked vortex antiferromagnet in A3V9Te13 — with Weyl points in the Cs compound and a ~27 meV SOC gap in Rb.

Panoramic modelling of single-cell transcriptomes at scale with CellNet
A 231-million-cell, 40-species model that paints genes and expression into a shared image learns rare cell states and even some withheld RNA, including across…

Parafermions in polarized $ν=2/3$ Fractional Quantum (Anomalous) Hall Heterostructures
Correlated edge disorder may be the friendlier path to Z3 parafermion zero modes on polarized ν=2/3 edges next to a superconductor.

Documenting Trofinetide Treatment Phenotypes in Rett Syndrome with a Dual-LLM Consensus Pipeline
Two LLMs must agree before a Rett-clinic note becomes a phenotype — 90.2% expert agreement, and 47 points above regex on diarrhea.

Variable Masking for Climate Emulation in ACE
Masking inputs and subtracting the global mean help an ACE climate emulator stop undercooking near-surface warming — including under unseen forcing.

Forecast lead time and the timing of crew deployment for weather-driven power outages using AI weather models
Call mutual-aid crews early: three-to-five-day skill loss is real, but waiting for a better forecast can still lose if fewer crews show up.

Singles in Disguise: Kepler's Low-SNR Single-Transiting Systems as Incompletely Detected Multis
Kepler’s extra low-SNR “single” planets look like compact multis whose other planets simply never transited into the catalog.

Plasma-Enabled Wideband Matching of Electrically Small Antennas
A few watts of capacitively coupled plasma act as a tunable negative capacitor, pushing an electrically small dipole past 100% fractional bandwidth at −6 dB.

ALMA2040: Submillimeter-wave Limb Sounding of Venus and Mars
A 0.01-arcsecond ALMA upgrade could limb-sound Venus and Mars at their atmospheric scale heights — turning spacecraft snapshots into four-dimensional climate r…

The role of friction on heave-induced motion of offshore drilling systems: modelling, analysis, and numerical experiments
In a coupled drillstring model, friction barely changes well-posedness — and can still move the stability margins that operators actually feel.

Gyrators for superconducting circuit design
A flux-charge Hamiltonian that always symplectic-reduces well-posed LCG circuits extends Tellegen’s gyrator duality to Josephson junctions and phase slips.
