Research on the spatial-temporal distribution of three-dimensional carbon footprint in different urban agglomerations in China.

This study expands the original two-dimensional carbon footprint model into a three-dimensional model form. Introduce two indicators of carbon footprint depth (CF) and size (CF) to form a three-dimensional carbon footprint model (CF), which is used to respectively represent the occupation and consumption of natural capital reserves by human activities' carbon emissions. Based on the 3D carbon footprint model, this paper calculated the CF, CF, and CF for four different urban agglomerations of China (BTH, YRD, PRD, and CY) spanning from 2000 to 2017.

Enhancing Waterproof Food Packaging with Janus Structure: Lotus Leaf Biomimicry and Polyphenol Particle Technology for Vegetable Preservation.

With the increasing demand for improved food preservation, conventional waterproof food packaging has proven inadequate because of its limited functionality. Although incorporating features such as antibacterial and antioxidant properties into packaging enhances protection, it can compromise the hydrophobicity of the involved material, thereby increasing the risk of contamination from external sources. To address this challenge, a robust and reliable barrier capable of simultaneously integrating multiple protective functions is required.

Identification of Proteoforms Related to Flower Petaloid Through Proteogenomic Strategy.

Effects of soil water on fungal community composition along elevational gradients on the northern slope of the Central Kunlun Mountains.

Soil fungi are essential to ecosystem processes, yet their elevational distribution patterns and the ecological mechanisms shaping their communities remain poorly understood and actively debated, particularly in arid regions. Here, we investigated the diversity patterns and underlying mechanisms shaping soil fungal communities along an elevational gradient (1,707-3,548 m) on the northern slope of the Central Kunlun Mountains in northwest China. Results indicated that the dominant phyla identified across the seven elevational gradients were and , displaying a unimodal pattern and a U-shaped pattern in relative abundance, respectively.

The splicing auxiliary factor OsU2AF35a enhances thermotolerance via protein separation and promoting proper splicing of OsHSA32 pre-mRNA in rice.

Heat stress significantly impacts global rice production, highlighting the critical need to understand the genetic basis of heat resistance in rice.

3D-printed ultra-sensitive strain sensors using biogels prepared from fish gelatin and gellan gum.

The long-term sustainable development of flexible electronic devices is limited by a reliance on synthetic polymers that pose dangers for humans and potentially severe ecological problems, as well as a reliance on conventional processing methods. This work aims to exploit 3D printing to develop natural biogels composed of fish gelatin and high acyl gellan gum for use as flexible sensors. The electrical conductivity and mechanical strength were remarkably enhanced through the environmentally friendly enzyme (transglutaminase) cross-linking and non-toxic ethanol modification treatment, which allows the development of 3D printed sensors for temperature, strain, and stress sensors.

An orphan viral genome with unclear evolutionary status sheds light on a distinct lineage of flavi-like viruses infecting plants.

Advancements in high-throughput sequencing and associated bioinformatics methods have significantly expanded the RNA virus repertoire, including novel viruses with highly divergent genomes encoding "orphan" proteins that apparently lack homologous sequences. This absence of homologs in routine sequence similarity search complicates their taxonomic classification and raises a fundamental question: Do these orphan viral genomes represent viruses? In 2022, an orphan viral genome encoding a large polyprotein was identified in alfalfa () and thrips (), and named Snake River alfalfa virus (SRAV). SRAV was initially proposed as an uncommon flavi-like virus identified in a plant host distantly related to family .
