Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

Geological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

Integrated one‐pot CRISPR‐Cas detection: Addressing strategies and future prospects

Interdisciplinary Medicine, EarlyView.
Integrated one‐pot CRISPR‐Cas detection significantly simplifies workflows, reduces cross‐contamination risks, and shortens turnaround times, making it highly suitable for point‐of‐care testing (POCT) and resource‐limited settings. Key challenges include system compatibility issues between Cas proteins and isothermal amplification, limited multiplexing

A Water Soluble Polymer as a Working Structural Model for Humic Acids: H-binding and Spectroscopic Properties

, 2008
HA occur ubiquitously in terrestrial and aquatic environments, indicating that many precursors and several formation pathways exist. Distinguishing among these pathways has been difficult because individual scientists have tended to concentrate their ...

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Aumento del contenido de ácidos húmicos en un carbón de bajo rango a través de la oxidación con aire y con peróxido de hidrogeno o ácido nítrico Increase of the content of humic acids in a low rank coal by oxidation with air and with hydrogen peroxide or nitric acid

Química Nova, 2013
Low-rank coals are an important source of humic acids, which are important in retention processes of water and nutrients in plants. In this study coal samples of Montelibano, Colombia, were oxidized with air at different temperatures and subsequently ...

Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...
