Morpho-functional innovations in Shibantan fossils fuel Ediacaran frond debates

The Ediacara biota represents Earth’s earliest complex macroscopic organisms, but their biology and ecology remain poorly understood. Here we report Dengyingia pennata gen. et sp. nov., an exceptionally preserved frondose fossil from the late Ediacaran ( ~550–543 Ma) Shibantan li...

Asymmetric Response of Land Precipitation Variability Under Carbon Dioxide Removal

Abstract Precipitation variability describes fluctuations between wet and dry conditions and plays an important role in shaping hydrological extremes and their societal impacts. Using idealized carbon dioxide removal experiments from CMIP6 models, we assess how precipitation vari...

Machine Learning-Assisted Nanozyme–Porphyrin Dual-Channel Sensor Array for Glycosaminoglycan Pattern Recognition

Abstract Selective discrimination of glycosaminoglycans (GAGs) is crucial for drug safety and quality control but remains challenging because GAGs share similar disaccharide repeating units and overlapping polyanionic features. Nanozyme-based sensor arrays offer a cross-reactive...

Features of Regional Compound Dry‐Hot Events Over the Yangtze River Basin in Warm Season and Related Mechanisms

Abstract Based on daily station observations and ERA5 reanalysis data during warm seasons of 1961–2024, the characteristics of regional compound dry‐hot events (RCDHEs) and associated mechanisms over Yangtze River Basin (YRB) have been systematically explored. Results show more t...

Age-Dependent Heterogeneity Trends in the Associations between Urban Green Space and Cardiovascular Health in a Humid-Subtropical Megacity

Abstract Urban green space (UGS) is a promising nature-based solution for cardiovascular health, yet its associative pathways in pollution-saturated, high-density environments remain contested. We applied a two-stage framework combining gradient boosting decision trees and struct...

Model-Based Multiframe Radiometric Spatial Reconstruction for Optical Satellite Video

Satellite video provides repeated observations of the same ground scene within short acquisition intervals, but blur, detector sampling, radiometric differences, noise, and registration errors complicate joint reconstruction. This study presents mixed sparse representation-based...

Coherent terahertz magnon–phonon three-wave mixing in a layered antiferromagnet

The coherent nonlinear dynamics between collective excitations, such as magnons and phonons, drive emergent phenomena in quantum materials, yet their direct observation remains limited. Here, using double-terahertz-pump optical-probe spectroscopy, we report the direct observation...

Kinematic relationship between solar extreme ultraviolet waves and type II metric radio bursts

Solar extreme-ultraviolet (EUV) waves are large-scale disturbances that manifest as bright wavefronts, often during coronal mass ejections (CMEs). According to the magnetic field line stretching model, this phenomenon comprises two components: a fast-mode CME piston-driven shock...

Balancing Interfacial Adsorption and Ion Migration Through a High‐Entropy‐Engineered Oxide for Durable Zinc Anodes

ABSTRACT Oxide coatings, owing to their electronic insulation and ionic conductivity, are promising artificial interfacial layers for stabilizing Zn anodes. However, conventional single‐phase, multiphase, and low‐entropy oxides remain insufficient to simultaneously address the co...

UAV-Satellite Integration Reveals Continuous Methane Emission Variability from Chinese Coal Mine Ventilation Shafts

Abstract Satellite quantification of coal mine methane lacks validation for continuously operating ventilation systems with high temporal variability. We integrate 75 unmanned aerial vehicle (UAV) flights (30 successful, 13 days) with 6.5 years of satellite observations at a Chin...

Temporoparietal structural-functional coupling abnormalities in drug-naïve youths with major depressive disorder and suicidal ideation

Major depressive disorder (MDD) in youth is associated with higher suicide risk. Although white matter and functional connectivity abnormalities have been reported in MDD patients with suicidal ideation (SI), how brain structure and function interact abnormally remains unclear. W...

Optimal Mixing for Randomly Sampling Edge Colorings on Trees Down to the Max Degree

Abstract. We address the convergence rate of Markov chains for randomly generating an edge coloring of a given tree. Our focus is on the Glauber dynamics, which updates the color at a randomly chosen edge in each step. For a tree [Formula: see text] with [Formula: see text] verti...

Statistics of Solar Filament Mass Based on CHASE Sun-as-a-star Spectroscopic Observations

Abstract Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequent eruptions and induced space weather effects, but it remains hindered by their intrinsic g...

Verifying Interrupt-driven Programs Efficiently via Heuristic and Reduced Partial-order Constraints

Interrupt-driven programs are extensively utilized in embedded systems for safety-critical domains. However, uncertain interleaving executions of enabled tasks with different priorities often lead to concurrency defects. In this context, assertion violation detection is a fundame...

Contrasting Terrestrial Moisture Controls on Precipitation and Interannual Variability across the Southern and Northern Tibetan Plateau

The Tibetan Plateau (TP) plays a crucial role in the Asian hydrological cycle, yet the dominant moisture sources and their governing physical processes remain debated. Here, we employ the Eulerian water tracer technique embedded in Community Earth System Model version 1 (CESM1),...

Effect of Fiber Dosage and Age on Creep Failure of Alkali-Activated Slag Concrete Under High Stress Sustained Loading

Alkali-activated slag (AAS) has emerged as a sustainable alternative to Ordinary Portland Cement (OPC), offering a viable pathway for mitigating global environmental footprints. However, its widespread structural application is often hindered by pronounced time-dependent creep de...

In Situ Peptide Assembly for Cancer Therapy

Peptides have emerged as promising anticancer agents due to their biocompatibility and functional versatility, such as tumor targeting and cell penetrating capabilities. However, their clinical application is often limited by poor stability and rapid clearance. To overcome these...

Low-Complexity Three-Layer GII Encoders Based on a Grouping Strategy

Generalized integrated interleaved (GII) codes have emerged as a compelling coding solution for distributed storage systems, as they achieve a favorable tradeoff between error-correcting capability and repair locality. Compared with conventional two-layer GII codes, three-layer G...

From creation to dissemination: a lifecycle-based evaluation of AI guidance policies in health-related journals

Abstract Background The rapid integration of generative artificial intelligence into health sciences research has prompted major advisory bodies to establish ethical guidelines governing AI use in scholarly publishing. However, practical implementation at the journal level remain...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...
