This research analyzes media coverage of government approaches to climate-health policy across 4 countries (USA, UK, Pakistan, and India) from 2015-2024, examining how newspapers portray governmental responses to climate change's health implications.

The authors proposed an integrated system combining intensive pig farming, rice cultivation, and biochar production leading to zero emissions goal. They also minimized the waste recovery cost, reduced greenhouse gas emissions and reused nutrients from pig farming waste.

This study examines teacher joy in outdoor learning contexts, addressing a gap in research on positive emotional experiences that support educator well-being. Findings show that joy arises through student growth, connections with nature, flexible teaching, and collaboration, highlighting its role in sustaining teachers and enhancing professional well-being.

This perspective explores the idea of the “Earth Grid,” which proposes an intercontinental electric grid facilitated by three technological advancements: enhanced information and communication technology (ICT) applications in the electric grid, development of inter-country grids for power-sharing, and the application of artificial intelligence (AI) for efficient operation and maintenance.

This paper examines how climate change and environmental factors impact rheumatic diseases, introducing the concept of planetary health and the exposome as frameworks for understanding these interconnections.

Researchers assess the critical mineral demand required to meet sustainability goals using a bottom-up, scenario-based approach and examine how mineral bottlenecks affect sub-technology choices.

This study examined how air pollution exposure affects asthma treatment effectiveness in Black children by reanalyzing data from the AsthmaNet BARD clinical trial. The researchers found that children with lower nitrogen dioxide (NO2) exposure had significantly better lung function improvements when treated with high-dose inhaled corticosteroids plus long-acting ?-agonists compared to children with higher NO2 exposure. The findings suggest that residential air pollution exposure, particularly NO2, may reduce the effectiveness of standard asthma treatments in Black children, highlighting the need to consider environmental factors in asthma management strategies.

This review examines how artificial intelligence (AI), machine learning (ML) and the Internet of Things (IOT) improve thermal efficiency, enable real-time system monitoring, and support predictive maintenance across solar, wind, geothermal, and bioenergy applications.

This study finds that optimal placement of long-duration energy storage in renewable-heavy power systems depends on multiple interacting factors—such as generation, demand, storage, and transmission—and cannot be determined by any single metric, with siting decisions having system-wide effects.

This article examines 42,291 renewable energy investment deals across OECD countries from 2004 to 2022, revealing highly international capital flows. Results show that $US 45.4B annually (45%) is invested across borders, with varying degrees between countries. Further, renewable energy investments increasingly mirror general foreign direct investment (89% correlation), indicating financial mainstreaming, which can contribute to rapid deployment.

This review highlights 3 primary criteria for selecting vegetation that supports ecosystem services while minimizing allergy risks. First, reducing the use of many wind-pollinated plants, such as birch trees and grasses, is crucial due to their high pollen production and cross-reactivity with other species, which can exacerbate allergies. In contrast, insect-pollinated plants are generally safer for allergy sufferers. Secondly, cultivating multispecies plant communities with minimal maintenance supports habitats for microbiota and invertebrates, further providing ecosystem services. Lastly, balancing plant gender ratios in urban spaces can help control pollen levels.

This study examines whether conducting lessons in natural outdoor environments, rather than traditional classrooms, influences students’ conceptual learning. Results show that younger students benefited cognitively from outdoor lessons, while older students performed better indoors, although both groups perceived natural settings as more restorative, indicating that the physical environment can shape learning outcomes.

Atmospheric water harvesting is emerging as a promising Earth?friendly technology to ease water scarcity, and new porous materials like MOFs and COFs could dramatically cut its energy use by efficiently capturing humidity even in arid climates. This review highlights how smarter material design can accelerate energy?saving AWH solutions for sustainable, decentralized water access.
