Perylenediimide Halogen Substitution-Modulated Photochromism and Photocatalytic Activity in Metal−Organic Frameworks

Abstract Perylenediimides (PDIs), which feature strong visible-light absorption, π-electron-deficient planes, and photochemical characteristics, offer a versatile platform for developing tunable and efficient metal−organic framework (MOF) materials through modulation of their bay...

Cross-sectional associations of generative AI acceptance with self-efficacy and well-being among students recruited from seven Chinese universities

Generative artificial intelligence (AI) is increasingly used in higher education, but its associations with students’ broader psychological outcomes remain uncertain. This cross-sectional study examined generative AI acceptance, general self-efficacy, and well-being among 495 stu...

Atmospheric Blocking Pattern as the Primary Driver of Subseasonal Greenland Ice Sheet Summer Melt Variability

ABSTRACT The anomalous summer melting of the Greenland Ice Sheet (GrIS) is one of the key signals of ongoing climate system changes. The complex spatiotemporal characteristics of GrIS and its impacts on global sea‐level rise have attracted increasing attention. Although previous...

AgEuPS4: Unlocking the CentrosymmetricShackle of Rare-Earth Thiophosphates via Microscopic Distortion Cascadingfor Enhanced Second-Harmonic Generation Response

Abstract Breaking the rigid centrosymmetric (CS) shackles of rare-earth thiophosphates remains a significant challenge for designing high-performance mid-to-far-infrared (MFIR) nonlinear optical (NLO) materials. Herein, using the CS LiEuPS4 (I41/acd) as the structural template, a...

Healing intervention for improving the efficiency and stability of tandem devices on industrial textured silicon

Monolithic perovskite/silicon tandem solar cells are widely regarded as the next-generation, low-cost, high-efficiency photovoltaic technology. However, achieving high-quality wide-bandgap perovskite top cells on industrial textured silicon, particularly using hybrid two-step dep...

Increasing Climate Constraint on Vegetation Productivity Under Rising CO 2 in Northeast Asia

Abstract Elevated atmospheric CO 2 enhances vegetation productivity through direct physiological and indirect climate‐mediated pathways. However, how the balance between these mechanisms evolves under continued CO 2 rise remains unclear. Here, we use CMIP6 Earth system models to...

Intra‐Bacterial Supramolecular Assembly of Peptide With RNA Activates MRI/Fluorescence Imaging and Avoids Drug Resistance

ABSTRACT Multidrug‐resistant Gram‐negative bacteria present a critical challenge for both diagnosis and therapy because diagnostic and therapeutic molecules have difficulty entering Gram‐negative bacteria, and these molecules can also be expelled by bacteria using efflux pumps. H...

Microglial immunometabolism in Alzheimer's disease: A stage-resolved trajectory from adaptive remodeling to the metabolic paradox

Microglia are central regulators of the cellular phase of Alzheimer's disease (AD). Under chronic exposure to amyloid-β, pathological tau, and aging-associated bioenergetic decline, these cells undergo immunometabolic remodeling that may initially be adaptive. As stress persists,...

Unlocking biological insight from single-cell data with an interpretable dual-stream foundation model

Abstract Deep learning foundation models are revolutionizing single-cell biology, yet learning holistic and discriminative representations from complex, high-dimensional data remains a central challenge. Although Transformer-based single-cell language models have shown significan...

Impact of ozone pollution on gross primary productivity during a large-scale emission reduction: Implications for strengthening carbon sink over megacity clusters in China

Ozone (O 3 ) pollution poses a significant threat to plant growth and diminishes ecosystem carbon sequestration capacity in China, representing a critical challenge to achieving “dual carbon” goals. A large-scale emission reduction that occurred during the Coronavirus disease 201...

Heavy‐Halide Coordination and Lattice‐Confined Molecular Alignment Enable Giant Birefringence in Hybrid Metal Halides

ABSTRACT High‐birefringence materials are essential for polarization optics, yet it remains difficult to translate anisotropic molecular building blocks into a strong directionally accumulated crystal‐scale optical anisotropy. Here, we establish a hybrid metal halide engineering...

Synergies and trade-offs for reaching global biodiversity and climate commitments

The Kunming-Montreal Global Biodiversity Framework strives to expand high-quality protected areas globally, yet faces economic constraints, climate change and human pressures. This requires integrating biological and socio-economic complexity while ensuring equity. We explore mul...

Glymphatic-meningeal lymphatic dysfunction drives remote organ injury after aneurysmal subarachnoid hemorrhage: a unified neuroimmune framework and time-stratified therapeutic roadmap

Aneurysmal subarachnoid hemorrhage (aSAH) confers substantial mortality and morbidity driven not only by primary brain injury but also by systemic remote organ complications across the pulmonary, cardiac, renal and gastrointestinal systems. Despite growing recognition of neuroimm...

Genetic architecture of node-specific leaf length and candidate gene identification in maize revealed by a temperate–tropical multiparental population

Abstract Background Optimizing leaf morphology is essential for improving maize plant architecture, plant density tolerance, and yield. Leaf length is a key agronomic trait controlled by complex genetic mechanisms. In this study, upper leaf length (ULL), ear leaf length (ELL) and...

Intraoperative titanium clip localization versus preoperative medical glue localization for pulmonary nodules: a prospective cohort study

Preoperative CT-guided percutaneous localization of pulmonary nodules is widely used in clinical practice but is often associated with localization-related complications. Intraoperative titanium clip localization may provide a safer localization strategy. This study aimed to comp...

Urban water system resilience and risk assessment in a typical arid industrial city: a case study of Karamay

This study develops a multi-dimensional framework to assess urban water resource resilience and risk in Karamay, a typical resource-based industrial city in arid northwest China. By integrating long-term data on water supply and demand, meteorological and hydrological conditions,...

DHPA: decomposition-enhanced hybrid spatiotemporal modeling for city-scale parking availability forecasting

The growing demand for urban parking has imposed increasingly stringent requirements on the real-time and fine-grained management of parking resources. Accurate parking availability (PA) forecasting is therefore essential for parking guidance and traffic congestion mitigation. Ex...
