Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

Small, EarlyView.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Sargassum Lung Syndrome: Air Flow Obstruction and Bronchial Inflammation Are Observed After Prolonged Exposure to Sargassum Gas Emissions in the Eastern Caribbean

Environmental Toxicology, EarlyView.
ABSTRACT Sargassum inundation of Caribbean and American shorelines is a growing environmental hazard. Hydrogen sulfide (H2S) and ammonia (NH3) produced by decomposing Sargassum could be involved in airway obstruction and bronchial inflammation. The study was undertaken to evaluate the effects of exposure to H2S and NH3 gases emitted during Sargassum ...

A retrospective on the 2025 Atlantic hurricane season

Weather, EarlyView.
The 2025 Atlantic hurricane season was intermittent, with extended quiet periods separated by three clusters of activity. The broad‐scale conditions were often unfavourable for cyclogenesis and common drivers of activity such as La Niña were weak, but well above‐average sea temperatures still supported intense storms.
