Picked for broad interest, a real step forward and honest claims, with no field allowed to take over.

  1. 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.

  2. Multidimensional Political Attitudes and Polarization Across 141 Countries

    A single left-right axis does not describe political division in most of the world.

  3. Direct 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.

  4. Co-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).

  5. Dual 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.

  6. Generation 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.

  7. Breaking 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.

  8. Distributed 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.

  9. JevAdvBench: 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.

  10. A 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.

  11. Uncertainty-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.

  12. A 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.

  13. Reprogramming 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.

  14. BeatGraph: 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.

  15. SN 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.

  17. A 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.

  20. Genetic 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.
