Viscosity of NaAlSi3O8−H2O fluids and implications for arc magmatism

Water plays a crucial role in the transport properties of silicate liquids and is especially important in subduction-zone magma source regions where conditions promote complete miscibility between water and silicate melts. However, accurately tracing the movement of fluids and vo...

Socio-hydrogeology: The past, present, and future of a people-centred and place-based approach to groundwater science

Groundwater systems are shaped by deeply interwoven physical processes and social dynamics, yet traditional hydrogeological approaches have often treated these domains separately. Over the past decade, socio-hydrogeology has emerged in response, offering an approach that systemat...

Little Red Dots host Black Hole Stars: A unified family of gas-reddened AGN revealed by JWST/NIRSpec spectroscopy

Abstract We construct and characterise a sample of 146 little red dots (LRDs) across 2.0 < z < 9.3, selecting all sources with v-shaped UV-optical continua from JWST NIRSpec/PRISM spectra and compact morphologies in NIRCam/F444W imaging. We show that LRD continuum spectra are wel...

Morphogenesis of bacterial colonies in liquid crystalline environments

Natural bacterial habitats are often complex fluids with viscoelastic and anisotropic responses to stress; for example, they can take the form of liquid crystals (LCs), with elongated microscopic constituents that collectively align while still retaining the ability to flow. Howe...

Conceptual Shift inOur Understanding of DegenerateRadical Spin Systems: Spin-Rotation Coupling Turned on Its Head

Abstract For most chemists, Kramers’ degeneracy refers to the fact that for any radical system, every potential energy surface is at least doubly degenerate (with spin up and spin down, time-reversed solutions) for all nuclear positions X. Yet, as is well-known to the community o...

Protein LanguageModel Decoys for Target Decoy Competitionin Proteomics: Quality Assessment and Benchmarks

Abstract Large-scale proteomics relies heavily on target–decoy competition for false discovery rate estimation in peptide identification, and the performance of this strategy depends strongly on the design of the decoy database. Classical generators such as reversal and shuffling...

Music evokes shared neural representations of imagined narratives across sensory modalities

The human capacity to construct and share subjective experiences from diverse sensory inputs is central to human cognition, and is vividly exemplified through music listening. Direct, focused music perception has been extensively studied while free, imaginative listening, typical...

Plasmon-Driven ChargeTransfer Aids Selective NonthermalVibrational Excitation in Nitrobenzenethiol on Silver Nanoparticles:Insights from Embedded Correlated Wavefunction Calculations

Abstract In plasmonic photocatalysis, a commonly invoked reaction enhancement mechanism is the excitation of a metal-to-molecule charge transfer state, resulting in transient-ion formation. Once accessed, a transient-ion state leads to changes in the molecular geometry that can l...

Coreless exoplanets induced by metal–silicate miscibility

The rocky interiors of exoplanets are generally expected to differentiate into a silicate mantle and a metallic core due to the immiscibility of metal and silicate under typical planetary formation conditions. Here, we use large-scale molecular dynamics simulations driven by mach...

Nanoscale sensing of spatial correlations in nonequilibrium current noise

Abstract Nitrogen-vacancy centers are spatially resolved probes of current noise. So far, current noise sensing with NV centers has primarily been used as a way to probe equilibrium transport coefficients. We develop a framework for computing the spatiotemporal correlations of no...

Atmospheric turbulence sensing with structured terahertz beams containing orbital angular momentum

Clear-air turbulence poses a persistent hazard to aviation, yet it evades conventional weather radar and remains difficult to detect. Existing optical sensing methods falter under severe turbulence and are extremely vulnerable to misalignment between airborne nodes. Here we intro...

Fast, unconditional reset and leakage reduction in fixed-frequency transmon qubits

Abstract On-demand qubit-state initialization is a prerequisite for quantum computation. We demonstrate such a protocol in a device consisting of fixed-frequency transmon qubits pair-wise coupled via tunable couplers — an architecture that is also compatible with the surface code...

Odorant receptor coexpression and multi-expression in the dengue mosquito

Drosophila olfactory sensory neurons tend to express a single ligand-specific receptor, following a one-receptor-per-neuron rule expected to apply broadly across insects. Recent work challenges this view by showing that some neurons in the mosquito Aedes aegypti coexpress multipl...

Drought dynamics explain once in a century yellow fever virus outbreak in Brazil with implications for climate change

While excess rainfall is associated with mosquito-borne disease because it supports mosquito breeding, drought may also counterintuitively increase disease transmission by altering mosquito and host behavior. This phenomenon is important to understand because climate change is pr...

Persistent Free Volume Governs (Anti)plasticization in Chitosan-Water Mixtures

Abstract Chitosan is a highly versatile and sustainable polymer with a broad range of potential biological and materials engineering applications. Despite its versatility, the native brittleness of chitosan limits its broader utilization. This limitation can be addressed by blend...

Eco-evolutionary feedback reshapes competitive dynamics in an orchard fly system

The feedback between competition and evolution is central to hypotheses about the origin and maintenance of species diversity. Yet, whether competition-induced evolution is sufficiently rapid, consistent, and strong to maintain diversity on ecological timescales remains unresolve...

High-resolution simulation and modeling of tropical-cyclone induced power outages in the United States

Storm driven power outages impose large and uneven costs on communities, yet operational outage prediction models remain constrained by available datasets. Existing approaches either provide high resolution forecasts for a small number of utilities with internal outage records, o...

Characterizationof Dapalides D and E and GenomicComparison of the Two Co-Occurring Dapalide-Producing Dapis spp.

Abstract Marine cyanobacteria are a rich source of diverse bioactive natural products, targeting proteins involved in many diseases. Here, we combined metagenomic analysis to enhance the structure elucidation process of two new cyclodepsipeptides named dapalides D (1) and E (2) f...

Economic Conditions and Incarceration in the United States: Evidence from Missouri, 1850–1930

This paper investigates the relationship between economic conditions and incarceration in the postbellum United States. Leveraging unique administrative prison records in Missouri from 1850 to 1931 and the differential exposure to national agricultural price changes across counti...

AI and the Decentering of Disciplinary Creativity

Abstract This paper examines the role of artificial intelligence in scientific problem-solving, with a focus on its implications for disciplinary creativity. Drawing on recent work in the philosophy of creativity, I distinguish between creative approaches and creative products, a...
