Hierarchical quasiparticle dynamics in antiferromagnets revealed by time- and momentum-resolved X-ray scattering

Abstract Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations —magnons— mediate these flows in ultrafast magnetism. Yet momentum-resolved access to low-energy magnons governing the microsc...

World model for robot learning: A comprehensive survey

World models, which are predictive representations of how environments evolve under actions, have become a central component of robot learning. They support policy learning, planning, simulation, evaluation, data generation, and have advanced rapidly with the rise of foundation m...

AX-35 Targets the Cytochrome bc1 Complex in Mycobacterium abscessus and Reveals a Novel Resistance Mechanism

Abstract In patients with cystic fibrosis, nontuberculous mycobacteria are opportunistic, intracellular and extracellular pulmonary pathogens that contribute to deterioration of lung function and, ultimately, morbidity from respiratory failure. Among nontuberculous mycobacterial...

Persisting perceptual abnormalities in psychedelic users are associated with conditioned hallucinations and impaired sensory processing

Abstract Serotonergic psychedelics (SP) are increasingly used in clinical research and naturalistic settings, but their psychotic-like side effects, including persisting perceptual abnormalities (PPAs), are poorly understood. Psychosis-associated hallucinations are associated wit...

Rapid Simultaneous Quantification of Four Typical Phthalate Esters in Complex Food Matrices via Thermal Desorption–Dielectric Barrier Discharge Ionization Mass Spectrometry

Abstract Conventional analytical methods for detecting and quantifying phthalate esters (PAEs) in foods generally require lengthy sample pretreatment procedures and suffer from severe matrix interferences. To address these shortcomings, a fast analytical platform based on a therm...

Existence of Spectral Submanifolds in Time Delay Systems

Abstract Spectral submanifolds (SSMs) are invariant manifolds of a dynamical system, defined by the property of being tangent to a spectral subspace of the linearized dynamics at a steady state. We show existence, along with certain desirable properties such as smoothness, attrac...

Real‐Time Monitoring of Mass and Mechanical Properties in Single Cells and Multicellular Spheroids

ABSTRACT Cell state, growth, and mechanics are tightly connected properties underpinned by fundamental biological processes. Yet methods to quantify them simultaneously under physiologically relevant conditions, at resolutions sufficient to follow (sub)cellular processes, are sti...

Groundwater regulates the spatial pattern of photosynthesis in the contiguous United States

Abstract Plants can access water stored in aquifers to sustain their activity, releasing moisture into the atmosphere—a critical survival mechanism during drought. Understanding the role of groundwater in regulating photosynthesis is thus key for modelling land-atmosphere interac...

Functionalization and Metal Ion Encapsulation Within a Triaxial Supramolecular Weave

ABSTRACT Molecular weaving has attracted much interest in recent years. Supramolecular organic weaves offer many benefits, such as error correction, but their functionalization is challenging, as even minor modifications to the building blocks can disrupt self‐assembly. In this s...

Alteromonas macleodii breaches the diatom frustule triggering protoplast emergence and programmed necrosis-like death in Thalassiosira rotula

Abstract Diatom-bacteria interactions drive biogeochemical fluxes at the base of the marine food-web. Although bacteria are increasingly recognised as important drivers of algal mortality, the diversity of algicidal strategies remains understudied. Here we show that Alteromonas m...

The social embeddedness of learning: Social network formation and academic achievement in an undergraduate student community

Background: Students play an active role in developing their social learning environment and peer relationships. Meanwhile, their academic behaviors are likely to be affected by their integration and individual positions in social networks. Despite the clear importance of social...

Multi-facility GNSS antenna calibration

Abstract Accurate antenna calibrations are a cornerstone of high-quality global navigation satellite systems (GNSS) positioning, time and frequency transfer, precise orbits, and troposphere estimates. The international GNSS service (IGS) antenna committee maintains antenna phase...

Uncertainties of GRACE/GRACE-FO Satellite Gravimetry Data and Thereof Derived Products

Abstract Inter-satellite ranging by space gravimetry missions, such as from the Gravity Recovery And Climate Experiment (GRACE) mission and its successor mission GRACE Follow-On, has been established to observe mass variations in the Earth system from space globally. A complex pr...

Zircon geochronology constraints on the geometry and solidification timescales of the Dufek layered mafic intrusion, Antarctica

Abstract The ~ 182 Ma Dufek Intrusion of Antarctica, associated with the Ferrar Dolerite Province, is a large layered mafic intrusion that is estimated to be similar in size to the 8–9 km thick Bushveld Complex of South Africa. Similar to the Bushveld Complex, the Dufek Intrusion...

Volatile depletion in rocky planets as a chemical fingerprint of hybrid accretion

Volatile depletion in rocky planets records their formation history. Earth and Mars grew through different hybrid pathways of pebble and planetesimal accretion, providing a new way to interpret the diversity of rocky planets beyond the Solar System.

A global mitochondrial genomic atlas illuminates freshwater microeukaryote diversity

Abstract Environmental genomics has transformed our view of the microbial world, yet progress remains largely prokaryote-centric. Among microbial eukaryotes, inconsistent marker choice and limited species-level resolution blunt diversity estimates and hinder cross-study synthesis...

Stimulatrix: An open-source automated platform for high-throughput functional characterization of engineered contractile tissues

Engineered cardiac and skeletal muscle tissues suspended between flexible posts support disease modeling and pharmacology, yet their stimulation, longitudinal imaging and quantitative analysis often remain fragmented and labor-intensive. Here we present Stimulatrix, an open-sourc...

Systematic mapping of bacteriophage gene essentiality with HIDEN-SEQ

Abstract The arms race of bacteriophages and their bacterial hosts has inspired major breakthroughs in biotechnology and shaped phages as fierce predators with great clinical potential to fight multidrug-resistant bacterial pathogens. However, the large amount of genes of unknown...

Probing picosecond depairing currents in type-II superconductors

Abstract Accessing the intrinsic critical current density in type-II superconductors can provide a means to probe microscopic superconducting properties and increase current limits in high-magnetic-field devices and electrical power systems. However, the critical current density...

Mind the Trust Gap: Identifying (Mis)alignments in Teacher-Student Views Toward Control and Agency in K-12 Classroom AI

As Artificial Intelligence (AI)-based technologies have been integrated into school classrooms where multiple stakeholders (with different roles) interact with each other, it is critical to deeply understand stakeholder views in the classroom. In particular, prior work has not fu...
