A Copula-based composite drought index for vegetation and hydrological droughts

Drought is a complex natural hazard with profound impacts on vegetation and water resources. However, existing monitoring approaches often treat vegetation and hydrological droughts separately, limiting a comprehensive understanding of their interactions. To address this gap, thi...

Computationally guided hapten design enables a colloidal gold immunochromatographic assay for rapid citalopram detection in water and dietary supplements

Citalopram, a widely prescribed selective serotonin reuptake inhibitor (SSRI), has emerged as an environmental and food contaminant owing to its extensive consumption and incomplete removal during wastewater treatment, posing potential risks to aquatic ecosystems and human health...

Quality Deterioration and Volatile Metabolite Profile of ‘Orah’ Mandarin During Low-Temperature Storage and Room-Temperature Shelf Life

Low-temperature stored mandarin was prone to rapid quality deterioration when moved to a room-temperature shelf (RTS). However, systematic research on the safe threshold of time for low-temperature storage (LTS) and the key metabolic mechanisms underlying the quality deterioratio...

Environmental Occurrence, Toxicity Concerns, Degradation Behavior, and Plant Resistance of Glufosinate-Ammonium

The market for traditional non-selective herbicides has undergone dramatic changes over the past decade. As an emerging herbicide, glufosinate-ammonium’s market share has been steadily increasing. However, with its widespread use, glufosinate-ammonium residues have been detected...

Enhanced oral bioavailability of ivermectin in pigs via a novel pH-sensitive enteric matrix granule formulation

Ivermectin (IVM) oral use is often limited by its instability in gastric acid and poor water solubility. Conventional oral formulations, such as premixes and tablets, are often associated with inaccurate dosing and variable bioavailability. This study aimed to develop a novel pH-...

Distribution Characteristics of Antimicrobial-Resistance and Virulence-Associated Genes of Bacillus cereus in Animal-Origin Food in Guangzhou, China

This study investigated the prevalence and genomic characteristics of Bacillus cereus group organisms in animal-origin foods sold in Guangzhou, China. A total of 505 retail samples, including 117 milk samples and 388 commercially available smoked sausage products, were collected...

H2O-gasification direct carbon solid oxide fuel cells utilizing biochar as fuel for high-performance electricity generation

H 2 O-gasification direct carbon solid oxide fuel cells (DC-SOFCs) show promise for operation at reduced temperatures. In this study, Camellia oleifera shell biochar is utilized in H 2 O-gasification DC-SOFCs to improve cell performance and broaden fuel applicability. The biochar...

Perilla frutescens (L.) Britton (Lamiales: Lamiaceae) cultivation repels red imported fire ant Solenopsis invicta Buren (Hymenoptera: Formicidae) through volatile organic compounds

The red imported fire ant (RIFA, Solenopsis invicta Buren) (Hymenoptera: Formicidae) is a highly destructive invasive pest that threatens agriculture, biodiversity, human health, and infrastructure worldwide. Current management heavily relies on synthetic chemical insecticides, b...

Integrated transcriptomic analysis of milk-derived RNA associated with divergent milk yield phenotypes in buffalo

Buffaloes are the second-largest milk-producing animals, and their milk possesses significant nutritional and health benefits. However, the relatively low milk yield severely limited the development of buffalo dairy products. Here, to explore molecular features associated with di...

Predicting the future of battery lifetime and knee point ultra-early at the formation stage

Early lifetime prediction can accelerate lithium-ion battery development, support factory-side quality control, and reduce testing-related energy consumption. However, most existing methods rely on post-production cycling data and long test windows, limiting manufacturing scalabi...

Thermoplasticization of Bamboo Fibers via Solvent-Free Heterogeneous Esterification with Long-Chain Fatty Acids: Effect of Lignin Removal and Carbon Chain Length

Abstract The development of bio-based thermoplastics from lignocellulosic biomass is of considerable interest for reducing dependence on petroleum-derived plastics. In this work, a solvent-free strategy was proposed to fabricate thermoplasticized bamboo fibers (TBF) via heterogen...

Carbon dot/rare-earth compound composites: design principles, synthetic strategies, mechanisms, and applications

The integration of carbon dots (CDs) with rare-earth compounds (RE-compounds) has emerged as an important strategy for constructing multifunctional photofunctional systems capable of overcoming the intrinsic limitations of single-component luminescent materials. Owing to their br...

Terminal Shoot Maturity Orchestrates LcSPL–LcFT1 Signaling to Dictate Low-Temperature Floral Induction in Litchi (Litchi chinensis Sonn.)

In perennial fruit trees, erratic floral initiation and alternate bearing represent major horticultural challenges, yet how vegetative shoot maturity conditions low-temperature responsiveness remains poorly understood. Here, using litchi (Litchi chinensis Sonn.) as a model, we de...

A robust biotechnology induces artificial genomic duplication via transient RNAi‐mediated suppression of OSD1 in rice

ABSTRACT Ploidy manipulation is a crucial strategy for generating germplasm in crop breeding. However, artificial genomic duplication, often induced by colchicine treatment, is associated with toxicity and unpredictability. Although mutations in OSD1 have shown promise for induci...
