Picked for broad interest, a real step forward and honest claims, with no field allowed to take over.
Collective order reorganizes dissipation and powers an active engine
These findings establish energetic fluxes as quantitative observables for understanding collective state transitions and demonstrate how collective order can be harnessed for work extraction in active matter.
PreprintClaims a big stepMultidimensional Political Attitudes and Polarization Across 141 Countries
A single left-right axis does not describe political division in most of the world.
PreprintClaims a big stepDirect Light Storage with Controlled Dark Release in a Bipyridine-Based Covalent Triazine Framework
Here, we reveal the light-induced, reversible electron storage properties of a two-dimensional (2D) 2,2′-bipyridine (bpy)-based crystalline covalent triazine framework (CTF), CTF-Bpy.
Peer-reviewed journalClaims a big stepReal-world useCo-design of trajectory and morphology for a vertical jump-climbing robot
In this paper we present a 290 g robot that, to our knowledge, is the first to climb vertically by bounding (with an aerial phase).
PreprintClaims a big stepDual Topological Channels in a Programmable Mechanical Metamaterial
Here we demonstrate that a single mechanical metamaterial can host two independent topological channels governing static and dynamic response within the same architecture.
PreprintClaims a big stepGeneration of 10-TW Attosecond X-Ray Pulses in a Free Electron Laser
Here we report the generation of soft-x-ray pulses with a duration of as and peak power on the order of 10 TW at the European XFEL.
PreprintClaims a big stepBreaking the Black Box: Byte-Level Boundary Inference of Real-World Antivirus Systems
In this paper, we present AVHunter, the first framework for inferring byte-level decision-critical regions of real-world AV products under a black-box threat model.
PreprintClaims a big stepReal-world useDistributed laser energy deposition enables fog-resilient optical communications
Here we demonstrate laser-assisted fog clearing under atmospheric-scale propagation conditions over a 140-m optical path using a high-energy, high-average-power picosecond laser and weak focusing to sustain extended multifilamentation.
PreprintReal-world useJevAdvBench: A Benchmark and Black-Box Attacks for Reinforcement Learning for Calibrated Decisions Models
Building on this, we introduce JevAdvBench, to our knowledge the first adversarial benchmark for RLCD models, with 812 typed questions over 66 scenarios, and a black-box attack suite of 9,744 single-edit variants that each edit one part of a request, with billed input tokens confirming that the edit reached the model.
PreprintClaims a big stepReal-world useA tidal disruption event in a quasar at redshift 7.19
We report a long-lived nuclear transient in GNz7q, a red quasar at powered by a black hole and hosted by a compact, dusty starburst galaxy.
PreprintClaims a big stepUncertainty-Aware Federated Learning for Infant Movement Analysis
To address these challenges, we present, to the best of our knowledge, the first federated learning framework for automated infant movement analysis and General Movement Assessment using skeletal motion data.
PreprintReal-world useA Long-Legged, Direct-Drive Monopedal Robot Achieves Exceptional Jump Height
We demonstrate a jumping robot that reaches high (7.6 m) and fast (190 ms stance time) jumps from a single long leg driven by a direct-drive transmission, without elastic energy storage.
PreprintClaims a big stepReprogramming energy system for growth and bioproduction from CO₂ and methanol in Escherichia coli
Integration of the OES-driven CAM* pathway with a rationally rewired native electron transport chain supports growth of the engineered E. coli on CO₂ and methanol, with a doubling time of 8.6 ± 0.3 h and a maximum OD₆₀₀ of 37.5 ± 5.8.
Peer-reviewed journalClaims a big stepReal-world useBeatGraph: Self-Supervised Heartbeat Graphs for Infant ECG Representations from the Home Environment
We propose BeatGraph, which makes the heartbeat its unit of representation, modeling each 30-second window as a graph of beats.
PreprintReal-world useSN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+1626.
PreprintClaims a big stepFederated Targeted Maximum Likelihood Estimation
To fill this gap, our paper introduces the first federated TMLE algorithm.
PreprintClaims a big stepA single-nucleus multi-omic atlas of gene regulation across 21 adult human tissues
Here we present a single-nucleus multi-omic atlas comprising 459,856 transcriptomic and chromatin accessibility profiles from 21 adult human tissues and four donors, including paired measurements from 160,688 nuclei.
PreprintClaims a big stepLearning a non-linguistic code for inferred rules from reward
Rewarded for the second's success, the first learns a code carrying rules to three-step transformations training never presents, which new learners acquire.
PreprintExcitation and Identifiability in the 2D Navier-Stokes equations
This paper develops, to the best of our knowledge, the first such excitation theory for a nonlinear partial differential equation.
PreprintClaims a big stepGenetic architecture of immune-mediated thrombotic thrombocytopenic purpura in Han Chinese individuals
In summary, we reconstructed the genetic architecture of TTP in East Asians and identified structural gatekeepers of autoimmunity, providing novel targets for precision medicine and ethnic-specific risk stratification.
