Air Quality and Economic Trade-Offs of Relaxing California’s Gasoline Volatility Limits

This study finds that relaxing California's stringent summer gasoline volatility limits would yield significant monthly production and consumer cost savings exceeding the monetized health impacts, despite causing a negligible increase in ozone levels due to the lower reactivity of winter-blend emissions.

From Wild Foods to Mixed Subsistence: Nonlinear Nutrition Transition among Hadzabe Foragers

This study challenges the linear model of nutrition transition by demonstrating that Hadzabe foragers have undergone a nonlinear dietary shift characterized by the simultaneous expansion of both wild and market-based food consumption, driven by complex social-ecological reconfigurations rather than simple substitution.

Mechanistic Pedotransfer Functions for Soil Property Prediction Integrating Process Based Modeling and Data Driven Approaches

This review synthesizes the development, theoretical foundations, and applications of mechanistic pedotransfer functions (MPTFs), which integrate process-based modeling with data-driven approaches to overcome the limitations of traditional empirical methods by offering greater physical realism, interpretability, and predictive capability for sustainable soil management.

Integrating GIS, Multi-Criteria Decision Analysis and Google Earth Engine for National-Scale Groundwater Potential Assessment in Zimbabwe

This study developed and validated a national-scale groundwater potential framework for Zimbabwe's data-scarce crystalline basement aquifers by integrating GIS, Google Earth Engine, and Multi-Criteria Decision Analysis, demonstrating strong predictive accuracy in delineating high-potential zones through the synthesis of eleven hydrogeological factors and extensive borehole data.

Dynamic Soil Properties of Regenerating Coastal Wetlands within Abandoned Agricultural Fields

Although regenerating coastal wetlands in abandoned North Carolina farm fields are accumulating soil carbon and vertical accretion, their current rates remain insufficient to keep pace with regional sea-level rise and their soil carbon stocks are significantly lower than those of native tidal marshes, indicating a need for active management to enhance resilience.

Historical and projected changes in tropical north and south Atlantic indices under different emission scenarios

This study evaluates the performance of seven CMIP6 models in simulating historical Tropical North and South Atlantic sea surface temperature variability and projects that under high-emission scenarios, these regions will experience intensified warming, prolonged anomaly persistence, and increased climate risks for West Africa.

Machine-Learning-Based Landslide Susceptibility Mapping Using an InSAR- Refined Inventory in the Mandi district, Northwestern Himalaya, India, Himalaya region

This study enhances landslide susceptibility mapping in the Mandi district of Northwestern Himalaya by integrating InSAR-derived ground deformation data to refine the landslide inventory and training an Extreme Gradient Boosting model, which significantly improves prediction accuracy and identifies slope, road proximity, fault distance, and rainfall as key controlling factors.

Magmatic Fertility Indicators of the Chagai Arc: A Systematic Review of Published Whole-Rock Geochemistry and Implications for Porphyry Cu–Au Prospectivity

This study systematically reviews published whole-rock geochemistry for the Chagai Arc in Pakistan using the Loucks et al. magmatic fertility framework to demonstrate that Reko Diq and Saindak exhibit fertile signatures indicative of porphyry Cu–Au prospectivity, while highlighting the need for a unified database to fully map the belt's exploration potential.
