Spatial heterogeneity and trade-offs of agricultural functions in plateau basin: A case study of Dianchi Lake basin, China.

Plateau basin, characterized by strong radiation, climate variability, and ecological fragility, pose complex challenges for agriculture, requiring a balance between production and ecological goals. The unclear mechanisms underlying the evolution and interaction of agricultural functions (AFs) constrain the formulation of spatial and environmental policies in plateau regions.This research aims to understand the dynamic changes and trade-offs among different AFs in a typical plateau basin.

Outcrossing preference in Magnolia ×soulangeana 'Hongyun' is associated with differential stigmatic ROS accumulation regulated by MsFERONIA-MsROP2-MsROBHD module.

As primitive angiosperms, bisexual Magnolia species evolved a relatively advanced mating system, namely facultative outcrossing, avoiding inbreeding depression meanwhile providing a certain reproductive assurance. Explosive advances have been made in the molecular understanding of pollen-pistil interactions in the past decades, especially emphasizing the role of FERONIA-RAC/ROP-RBOHD module. However, relevant molecular framework in primitive angiosperms remains largely unknown.

The potential impact of forest landscape patterns on land surface temperature and carbon stock using highly reliable satellite observations and climate models was assessed.

Enabling High Capacity and Durable Si Anodes Through Simultaneous Construction of CNTs Assembled Network Wrapping, Surface Co Decorating, and Conformal Carbon Coating.

Herein, this work demonstrates a simple structure engineering strategy to construct in situ grown carbon nanotubes (CNTs) assembled 3D network wrapping surface cobalt (Co) nanoparticles (NPs)-decorated and conformal carbon-coated irregular silicon (Si) NPs (Si NPs@CNT@Co) for achieving high and durable lithium storage performance. It simultaneously integrates CNTs assembled 3D network wrapping, surface Co decorating and conformal carbon coating into Si NPs. The findings confirm that these structural characteristics enable Si NPs@CNT@Co to achieve improved electrochemical kinetics (smaller charge transfer impedance and activation energy, and higher Li ion diffusion coefficient and electric conductivity) and structural durability (more stable LiF-rich solid electrolyte interphase (SEI) layer, and smaller electrode expansion ratio) over the pristine Si NPs and Si NPs@CNT counterparts.

Landscape changes elevate the risk of avian influenza virus diversification and emergence in the East Asian-Australasian Flyway.

Highly pathogenic avian influenza viruses (HPAIV) persistently threaten wild waterfowl, domestic poultry, and public health. The East Asian-Australasian Flyway plays a crucial role in HPAIV dynamics due to its large populations of migratory waterfowl and poultry. Over recent decades, this flyway has undergone substantial landscape changes, including both losses and gains of waterfowl habitats.

Mutations mark cell lineages and sectors in flowers of a woody angiosperm.

While radial sectors of flowers are likely to accumulate nested mutations, the distribution of natural somatic mutations across floral organs in dicot plants has not been studied previously. Here, we use next generation sequencing of 78 independent genome samples through sepals, petals, stamens, and carpel of two flowers to ask 1) whether radial sectors accumulate nested mutations, 2) whether carpels share de novo mutations with the radial parts, and 3) whether mutations can be used to estimate founder cell numbers in the floral anlagen. Mutations described seven sectors, each including a single petal and adjacent sepals, consistent with radial cell proliferation in the floral cup that predates the split of the sepal and petal cell populations.

Glaucoma is a serious eye disease characterized by damage to the optic nerve, potentially leading to severe vision loss or even blindness. Lowering IOP is a crucial strategy in managing the disease. Although trabeculectomy is considered the gold standard in conventional treatment for preventing vision loss, surgical interventions often face challenges such as poor prognosis, high failure rates, and complications.

Ultrafast Construct Local Acidic Microenvironment of Boron-Intercalated Osmium with Anti-Precipitation and Corrosion-Resistant for Seawater-splitting.

Seawater electrolysis represents a promising avenue for hydrogen production, nevertheless, the Cl corrosion and surface deposition of Ca(OH)/Mg(OH) hinder its practical application by deactivation. Herein, an interstitial boron doped osmium (B-Os) is ultrafast (10 s) constructed by microwave quasi-solid approach, where theoretical and experimental analysis proves that the interstitial boron triggers electron enrichment at the Os site and the formation of negative charge centers. The modified electronic structure electrostatically inhibits Cl corrosion as well as promotes HO adsorption, creating a local acidic microenvironment in the natural seawater, neutralizing OH and effectively avoiding Ca/Mg deposition.
