Article Abstract
Artificial light at night (ALAN) can have negative impacts on the health of humans and ecosystems. Marine organisms, including coral reefs in particular, rely on the natural light cycles of sunlight and moonlight to regulate various physiological, biological, and behavioral processes. Here, we demonstrate that light pollution caused delayed gametogenesis and unsynchronized gamete release in two coral species, Acropora millepora and Acropora digitifera, from the Indo-Pacific Ocean. Given the urbanization along major coasts, light pollution could thus further threaten coral communities' populations, which are already under severe degradation. A worldwide-modeled light pollution impact assessment is provided, which can help incorporate an important variable in coral reef conservation planning.

Photocatalysis has emerged as a promising strategy to address water pollution caused by heavy metals and antibiotics. Zeolites exhibit significant potential in petrochemical catalysis; however, the development of zeolite-based photocatalysts remains a critical challenge for researchers. Herein, a novel Z-scheme heterojunction was designed and fabricated on the titanium-silicon zeolite TS-1 by modifying g-CN via a simple calcination process.

Artificial light at night (ALAN) can disrupt numerous biological processes, and is increasingly studied in animal models. Here, we evaluated the impact of red and blue ALAN on Drosophila melanogaster, focusing on fertility, development, circadian rhythms, and gene expression. All results were compared to those of a control group maintained under a 12 h white light/12 h dark cycle.

Bismuth ferrite (BiFeO), a perovskite oxide with both ferroelectric and antiferromagnetic properties, has emerged as a promising material for environmental cleanup due to its piezo-photocatalytic activity. The material's ability to degrade organic pollutants, such as azo dyes, under both light irradiation and mechanical stress (ultrasonic waves) offers a dual-action mechanism for efficient wastewater treatment. In this work, we explore the synthesis of BiFeO nanoparticles a simple sol-gel method, followed by characterization of their structural, magnetic, and photocatalytic properties.

Carbonized wood has great potential as a self-supported electrode for energy storage/conversion applications. However, developing efficient and economical bifunctional electrodes by customizing the surface structure remains a challenge. This study proposes a novel multifunctional electrode design strategy, using N/P co-doped carbonized wood (NPCW) as carriers and in situ grows copper nanoparticles (Cu NPs) as nucleation centers to induce vertical growth of CuCo-layered double hydroxid (LDH) nanosheets along the substrate.
