Alkali Metal Cation‐Regulated Interfacial Electric Fields Enable Selective C─H Oxidation via Reactive Oxygen Species

ABSTRACT Precise control over C─H oxidation remains challenging due to the intrinsic coupling between the generation and reactivity of oxygen‐based oxidants. Here, we identify the interfacial electric field as an effective reaction coordinate that decouples these processes, enabl...

High-fidelity spatiotemporal evolution of CO₂ storage in saline aquifers: A physics-synergized deep learning framework for CO₂ plume prediction and super-resolution reconstruction

Abstract Precise forecasting of spatiotemporal CO₂ plume evolution in deep saline aquifers is imperative for ensuring the long-term integrity and efficacy of carbon capture and storage. However, a persistent dichotomy exists in current modeling paradigms: high-fidelity numerical...

Time-boundary scattering and topological resonant transmissions

Time boundaries (TBs), temporal analogues of spatial interfaces, offer a powerful handle to engineer quantum systems. However, unlike the well-developed stationary scattering theory at spatial interfaces, a unified framework for quantum scattering at TBs has been missing. Here we...

Superradiant phonon laser with collective spin control

Hybrid systems consisting of phonon resonators and solid-state spin ensembles offer a unique opportunity for the study of emerging driven-dissipative quantum many-body physics. Our theoretical analysis shows that in such a phonon-matter hybrid system, the interplay of coherent an...

Ecological fitting in a deceptive trap flower: Aristolochia gibertii recruits native drosophilid flies outside South America

Deceptive pollination, in which plants lure pollinators without offering rewards, represents a sophisticated evolutionary strategy. The trap-flowers of Aristolochia provide an excellent system to study the coordinated evolution of floral morphology, chemistry, and phenology. Howe...

New constraints on cosmic-ray boosted sub-Gev dark matter via light mediators

Abstract Traditional direct detection experiments lack the sensitivity to probe the sub-GeV dark matter(DM), primarily due to the low energy of the expected nuclear recoils. In this work, we investigate cosmic-ray (CR) upscattering as a mechanism to accelerate DM particles to det...

Comparative metabolomics, network analysis, and fraction-based in vitro evaluation of three Lagerstroemia species reveal bioactive compounds and potential for sustainable industrial applications

Lagerstroemia plants are widely cultivated as ornamental trees, while also being traditionally used in China and Southeast Asia as functional tea beverages, fragrant flowering trees, and herbal medicines, indicating their potential as industrial crops enriched with high-value bio...

Nuclear tests at Mt. Mantap have reactivated intraplate faults

Underground nuclear explosions typically produce short-lived seismic sequences that decay rapidly after testing ceases. By contrast, seismicity near the Punggye-ri nuclear test site at Mt. Mantap in the Democratic People’s Republic of Korea has persisted and intensified for years...

Sleep quality is associated with gut microbiome signatures of hyperuricemia in Chinese elderly adults: a community-based case–control study

Hyperuricemia (HUA) has become a global health issue due to its rapidly increasing prevalence. Growing evidence from population and animal studies suggests that gut microbial dysbiosis and lifestyle changes are involved in serum uric acid metabolism. However, most existing studie...

City-Scale Assessment of Rooftop Photovoltaic Carbon Mitigation in China Using Semantic Segmentation and Interpretable Machine Learning

Urban rooftop photovoltaics (URPV) are crucial for decarbonizing China’s building sector, yet large-scale assessment remains limited by difficulties in rooftop extraction, cross-city generalization, and linkage to forward-looking decarbonization strategies. This study developed a...

Gas absorption of soft X-rays strongly impacts the redshift distribution of dark Fast X-ray Transients

Abstract The progenitors of many Fast X-ray Transients (FXTs) and those of γ-ray bursts (GRBs) are strongly linked. Given that ”dark” GRBs are typically found to be events suffering from enhanced extinction in the host galaxy, we investigate the nature of ”dark” FXTs. However, un...

Enzyme-mimicking peripheral substituents beyond the second coordination sphere tune single-atom catalysts for periodate activation

Abstract Single-atom catalysts (SACs) are promising enzyme-mimetic active centers, yet mimicking long-range regulation by distal binding pockets in natural metalloenzymes remains challenging. Here, we synthesize conjugated organic SACs bearing tunable peripheral substituents beyo...

Experimental Measurement and Artificial Neural Network Prediction of Dew Point Pressure for Ultra-Deep Condensate Gas

The development of oil and gas resources in global petroliferous basins has extended from shallow to deep reservoirs. Dew point pressure (Pd) is a vital parameter for fluid characterization and field development. Accurately and quickly obtaining Pd is crucial for the development...

An integrated remote sensing framework reveals zone-specific ecological response trajectories to open-pit mining on the Qinghai-Tibet plateau

Rapid mining expansion on the Qinghai-Tibet Plateau threatens its fragile alpine and arid ecosystems, with complex and spatially heterogeneous impacts, underscoring the need for long-term quantitative monitoring to support effective management. To address gaps in prior work that...

A physics-informed spatiotemporal downscaling model for kilometer-scale hourly humid heat stress indices

High-resolution humid heat stress indices, characterizing the interactive physiological effects of temperature and humidity, are vital for precision heat-health assessment and climate adaptation. However, existing coarse-resolution datasets smooth fine-scale spatial heterogeneity...

Net carbon losses in Central African forests revealed by high-resolution biomass change maps

Dense humid forests in Central Africa hold vast biomass carbon stocks but are increasingly affected by small-scale disturbances that are difficult to detect with current satellite observations. Here, we generate 10 m canopy height maps for 2019–2022 using deep learning with space...

Nano-NucleOTAC-mediated Z-DNA transformation disrupts mycobacterium tuberculosis biofilms and activates antibacterial immunity

The biofilms of Mycobacterium Tuberculosis (Mtb) use extracellular DNA (eDNA) as a protective structural scaffold that shields resident bacteria from host immunity and antibiotics, promoting persistent infection. An FDA-approved DNase can partially hydrolyze eDNA but has limited...

Emerging compound air-soil heatwaves amplify global vegetation losses

Abstract Compound air-soil heatwaves—periods in which extreme air and soil temperatures co-occur—pose a growing threat to terrestrial ecosystems, yet their occurrence and impacts remain poorly understood. Here, we show that compound air-soil heatwaves have become more frequent (0...

Flood-Induced Shifts in Nitrogen Speciation Alter Nitrogen-Transforming Microbial Communities and Functional Potentials in a Shallow Lake Ecosystem

Nitrogen cycling in freshwater lakes is mediated by diverse microbial communities, yet how nitrogen-transforming communities respond to flood perturbations across multiple habitats remains poorly characterized. In this study, we investigated nitrogen forms and associated microbia...
