Assessing synergies and trade-offs among water yield, sediment retention, and carbon storage in Yunnan Province, China

Understanding the spatiotemporal dynamics and interactions of ecosystem services (ES) is critical for regional ecological governance. Taking Yunnan Province, a key ecological barrier in southwestern China, this study quantified water yield (WY), sediment retention (SR), and carbo...

RetFL: a privacy-preserving and traceable framework for robust federated learning

Federated learning (FL) enables multiple clients to jointly train a model without sharing raw data. Decentralized federated learning (DFL) further removes the need for a trusted central coordinator in the aggregation process. However, in decentralized settings, model aggregation...

A Selective ERα Photodegrader for Precise and Efficient Breast Cancer Treatment

Abstract Breast cancer is the most prevalent malignancy in women, with over 70% of cases being estrogen receptor α (ERα)-positive. Photodynamic therapy (PDT) is spatially precise yet limited by tumor-selective photosensitizers. Herein, we report the first co-crystal structure of...

A Highly-Sensitive Electrode with Tubular Structure for the Detection of AA in Orange Juice

In this work, a three-dimensional (3D) tubular composite electrode was fabricated for the high-sensitivity electrochemical detection of ascorbic acid (AA). The differential pulse voltammetry (DPV) was employed to investigate the electrochemical behavior of AA at the composite ele...

Nonlinear controls on nitrogen export across heterogeneous riparian zones in a karst catchment: Insights from an integrated habitat classification framework

Identifying the spatial heterogeneity of riparian zones and its regulatory mechanisms on nitrogen migration is crucial for the prevention and control of non-point source pollution in watersheds. However, the influence of complex habitat characteristics in karst watersheds on nitr...

Tsukamurella tyrosinosolvens P9 enhances drought tolerance and recovery in peanut via regulation of stress resistance and rhizosphere microbiome

Plant growth-promoting rhizobacteria (PGPR) have been widely reported to enhance crop drought tolerance; however, mechanisms of rare actinomycetes across the drought-rewatering-maturation continuum in peanut remain unclear. Here, we investigated the effects of inoculation with Ts...

Soil moisture variation plays an important role in shaping the rhizosphere microbial community assembly of Pinus massoniana

In subtropical forest ecosystems, water availability and forest type are important environmental factors influencing soil microbial community structure. However, with the development of conifer–broadleaf mixed plantations, how water availability and forest type interact to influe...

Sedimentary Environment and Organic Matter Enrichment of Shale under Tectonic-Depositional Differentiation from the Lower Cambrian Niutitang Formation Guizhou, South China

Abstract To investigate variations in depositional environments and organic matter (OM) enrichment across different tectonic deformation zones, this study analyzed samples from three wells with contrasting deformation intensities: QinX1 (strongly deformed), YF1 (moderately deform...

Development and validation of a machine learning model for predicting refracture risk in older adults with osteoporotic vertebral compression fractures

Osteoporotic vertebral compression fractures (OVCFs) are common among older adults and are associated with a high risk of subsequent vertebral refracture, which may result in functional decline and reduced quality of life. However, effective tools for identifying Older Adults at...

Research Progress and Prospect of Ultralow Phosphorus Steel Smelting Technology

Ultralow phosphorus steel (phosphorus content ≤ 0.005%) is a key material for high‐end equipment manufacturing in fields such as nuclear power, marine engineering, and high‐pressure vessels, where phosphorus content control is the core technology. Molten steel dephosphorization i...

Xinjunan Binds to Pseudomonas syringae Pv. Actinidiae FleQ to Inhibit Flagella and Biofilm Formation and Reduce Pathogenicity

Abstract Pseudomonas syringae pv. actinidiae (Psa) is a devastating kiwifruit pathogen causing severe economic losses. In this study, Xinjunan (dioctyldiethylenetriamine) exerts potent antibacterial activity against Psa (EC50 = 4.29 mg/L), outperforming thiodiazole-copper (34.8 m...

Earth Observation of Ecological Restoration Effectiveness and Ecosystem Functional Recovery in the South China Karst: From Greenness Monitoring to Functional Verification

Long-term Earth observation has reliably documented vegetation greening, biomass increases, and the mitigation of rocky desertification across the South China karst. However, “greening” alone neither demonstrates an incremental effect of ecological restoration interventions nor s...

Ecological risk assessment of migratory bird feces in plateau wetland: Phosphorus speciation, ARGs, and pathogens

Plateau wetlands are critical habitats for migratory birds, but the potential ecological risks from the large-scale accumulation of migratory bird feces (MBF) remain poorly understood. This study focused on seven wintering waterbird species, including the Grus nigricollis , Grus...

Egg volatiles of oak silkworm mediate defense against parasitoid wasps

Most insects protect their eggs from natural enemies via physical coverings, yet defensive mechanisms of exposed eggs (i.e., those without such coverings), particularly those lacking toxins, remain largely unexplored. The oak silkworm (Antheraea pernyi) lays such exposed eggs, ye...

Underground Signals: The Ecological Power of Root Volatiles

Root volatiles mediate diverse belowground interactions among plants, microbes, and invertebrates, but biological and environmental conditions strongly influence their production, movement, perception, and ecological effects. This review synthesizes current knowledge through an i...

Triple-crosslinked network engineering of cellulose aerogels for intrinsically ultrahigh flame retardancy and thermal shielding

Background Developing environmentally friendly cellulose aerogels with excellent flame retardancy and thermal protection remains challenging because of the inherent flammability of biomass and insufficient structural stability under high temperature conditions. Methods In this wo...

Height-threshold-dependent estimates of forest gap characteristics, spatial patterns, and dynamics: Evidence from multi-temporal UAV–LiDAR

Forest gaps record disturbance, regeneration, and canopy structural change, yet estimates of gap closure depend strongly on the height threshold used to define when a gap is considered closed. This issue is particularly relevant for three-dimensional LiDAR analyses, where gap str...
