This study projects that humanity's capacity for sustained physical activity will significantly decline over this century due to the combined effects of climate change and population aging, rendering many common work and household tasks unsafe in increasingly frequent heat conditions, particularly for older adults in tropical regions.
This study evaluates the use of forage fish (mummichog and banded killifish) as cost-effective bioindicators for monitoring polychlorinated biphenyls in the Anacostia River watershed, identifying Lower Beaverdam Creek as a major PCB source and providing strategic recommendations to support sediment cleanup and source control efforts.
Using the UK as a case study, this paper demonstrates that adopting a "geological net zero" framework, which strictly balances fossil emissions with geological-scale carbon storage, could enable the country to reach net zero by 2040 and achieve significant emission reductions compared to current policies, despite the approach's reliance on vulnerable technology and supply chains.
Experimental evidence showing that interfacial-energy-driven rounding of ferropericlase grains occurs faster than mantle-flow-induced elongation indicates that the Earth's lower mantle viscosity is controlled by the stronger bridgmanite phase, making it orders of magnitude higher than previously hypothesized.
This study demonstrates that increasing the hydrogen content in aviation fuel significantly reduces soot and contrail formation, offering a physically grounded strategy to mitigate aviation's climate impact by potentially offsetting 21% of the projected temperature rise from the sector by 2050.
This study utilizes high-resolution satellite data and landscape metrics to reveal that the Katavi landscape in western Tanzania is undergoing significant woody encroachment and rangeland fragmentation alongside emerging peripheral human pressure, highlighting the critical need for integrated land-use planning that addresses both habitat extent and ecological connectivity.
This study demonstrates that historically redlined neighborhoods in Baltimore have nearly twice the arterial road density of non-redlined areas, highlighting a significant link between historical structural racism and the built environment factors that contribute to pedestrian injury disparities.
This study utilizes Multi-Angle Imaging Spectroradiometer (MISR) data from 2006 to 2030 to analyze the three-dimensional distribution and seasonal persistence of atmospheric turbidity in Iran, revealing that the Caspian Sea and Mazandaran wastelands experience significantly higher turbidity levels compared to the country's arid central and eastern regions.
This paper proposes a topological free-energy framework that models continental assembly within the Wilson cycle as a measurable, falsifiable selection process driven by a gradient of five topology-state coordinates, supported by existing simulation data and a reproducible analysis pipeline, while outlining a future validation protocol using public geological reconstructions.
This study analyzes five years of air quality data (2013–2017) in Bukit Rambai and Muar, revealing that while the regions generally experienced good to moderate air quality, they faced severe, episodic pollution spikes—most notably in June 2013—driven by transboundary haze events.
