Center-of-Mass Interpretation of Evolution Strategies
Evolution strategies (ES) update a model by sampling a population of perturbed copies, scoring each one, and moving in the reward-weighted direction of the perturbations. This update is usually presented as an estimate of a smoothed gradient. We present a geometrical interpretation of this update instead. Treat each perturbed model as a particle and its reward as the particle's mass. Before scoring, every particle has the same mass and the population balances at its centroid. Once rewards are as
Information-theoretic entropy imaging of quantum matter
Phase transitions can generate intricate spatial organization invisible to spatially averaged probes, yet quantitative measures of this organization remain limited. Here we develop "entropy imaging," an information-theoretic technique that harnesses lossless compression to quantify spatial complexity, predictability, and order in quantum materials. Using this approach, emergent spatial textures can be imaged and converted into an experimentally-accessible observable: the computable information d

Tehran remains firm on demands despite diplomatic urgency to prevent escalation in the ongoing US-Israeli conflict.
Model Selection for Off-Policy Evaluation via Pairwise Bellman Validation
Model selection and hyperparameter tuning pose a central challenge in off-policy evaluation (OPE) because errors of fitted Q-functions and occupancy-ratio estimates cannot be directly evaluated from held-out transitions. Bellman-residual and minimax validation methods often require auxiliary regressions or optimization over separate critic classes, adding computational and tuning costs. We introduce pairwise Bellman validation (PBV), a tuning-free minimax procedure for selecting among finite cla
Noah Wyle Crowned PEOPLE's 2026 Sexiest Man Alive

Apple iPhone Duo review: Two screens, two experiences, two thousand dollars
I understand the appeal of foldable phones—they let manufacturers keep expanding screen sizes while still producing devices that can reasonably fit in a pocket. In practice, though, every foldable Android phone I've seen in public has had a ridiculously visible seam between the two halves of the screen, often with what looks like delamination from the underlying surface, giving the display an ugly, bubbly appearance. Back when Android phones began shipping with bigger and bigger screens and the iPhone was stuck at a miserly four inches, I was jealous.
Third harmonic generation in the transition metal trichalcogenides
The transition metal trichalcogenides (TMTs) are an interesting class of layered 2D materials that have strong anisotropic electrical and optical properties. We report on the polarization-dependent nonlinear optical response of exfoliated crystals at the third harmonic using non-resonant excitation with a 1560 nm femtosecond laser. All members of the TMT crystal family explored (ZrS3, HfS3, TiS3, and NbS3) display large anisotropy in their polarized third harmonic generation signal, with anisotr

Retriever-Free Retrieval: Navigating Documents with Decision Models
While language models have become dramatically more capable, retrieval still largely relies on lexical matching or similarity in fixed embedding spaces. This creates a capability asymmetry: what the retriever fails to find, even the strongest generator cannot recover. We propose DecisionRAG, which brings the capabilities of pretrained language models to retrieval using decision models that jointly evaluate candidate branches in a single forward pass, without generating any tokens, and show that

Dynamic heart rate variability for classification of arrhythmia burden
Purpose: Heart rate variability (HRV) may provide information beyond heart rate (HR) for identifying arrhythmia burden, but the value of temporal HRV variation remains unclear. This study developed a dynamic HRV measure quantifying the interquartile range of window-level root mean square of successive RR-interval differences (IQRRMSSD) and evaluated its utility in classifying total abnormal-beat and premature ventricular contraction (PVC) burden compared with the conventional RR-based HRV measur

This is the one retirement expense that you might have forgotten to plan for
People often underestimate some expenses when planning for retirement. In my conversations with older adults about their in-retirement finances, they’ve repeatedly mentioned the cost of dental care. The reasons are straightforward: Our teeth get worse as we age, and yet dental care isn’t covered by Medicare (except for emergency dental procedures for people who are hospitalized).There are three main avenues to covering dental costs during retirement: dental insurance, a Medicare Adva

US officials want Section 702 renewed before damaging court ruling goes public
Two Democratic senators who have long overseen US intelligence say the Trump administration is illegally withholding a secret court’s findings from Congress until lawmakers renew a program that lets federal agents read Americans’ communications without a warrant. Seven months ago, the Foreign Intelligence Surveillance Court objected to search filters that let intelligence analysts pull Americans’ messages from intercepted data without the approvals, written justifications, or records the law requires. The court approved another year of surveillance anyway.
Ukraine improves drone interception rates despite Starlink disruptions
Ukraine made significant progress in countering Russia's jet-powered drones, with some air defence units reporting interception rates around 80%. But recent restrictions on US satellite services exposed Kyiv's reliance on US technology as it races to develop cheaper, more effective interceptors.

Want to be happier? Oxford research says ask yourself these 3 questions
What does it take to be happy? Three simple and surprising questions may hold the answer, research found. While most of us seek more money and greater achievement as paths to happiness, these questions are all about connection. They’re more strongly associated with self-measured life satisfaction than either money or success. That’s according to the 2025 World Happiness Report published by Oxford University and based on a study of people in 147 countries. The questions are: How often do you e

Sculpture recreates odd optical effects of famed Lycurgus Cup
Dating back to around 400 CE and made of dichroic glass, the Lycurgus Cup is notable for exhibiting different colors depending on the light. (It gets its name from the scene depicted on its surface, of King Lycurgus of Thrace.) Light it from the front, and the cup looks green; light it from behind, and the color changes to a deep red. University of Sheffield scientists have recreated the original recipe to produce a contemporary glass sculpture with the same optical effect. The cup is considered one of the seven glass wonders of the world, one of just 40 glass cage cups that survived.

A theory of noisy linear recurrent neural network learning dynamics
Biological neural networks are noisy: their dynamics involve difficult-to-predict fluctuations which are likely due not just to chaos, but also to a variety of low-level biophysical processes. Despite the omnipresence of intrinsic noise, its theoretical consequences are incompletely understood, especially in the context of learning. For example, does noise meaningfully shape representation learning, or is it better viewed as a nuisance factor whose presence or absence changes little about what s

Adequacy radii for stepped-wedge trials with time-varying effects
Complete stepped-wedge designs guarantee eventual intervention delivery, but their final periods contain no concurrent controls. Under exposure-time heterogeneity this creates a design-analysis tension: a constant-effect analysis can be precise while targeting a design-dependent contrast, whereas an exposure-time indicator (ETI) analysis targets a prespecified time-averaged effect but may be much less precise. We develop an adequacy radius that quantifies the size of exposure-time heterogeneity

On the stability of learning
Learning algorithms are usually analyzed under the assumption that informative gradients are continuously available. But this is not always true---learning signals in biological neural networks, for example, may be sparse, local, and only intermittently available at any given synapse. In this work, we show that if gradient information is noisy and only intermittently available, learning may be unstable. In particular, even if average learning dynamics converge to the correct optimum, variance in
