Taphonomic Patterns of Elemental Enrichment: Synchrotron X-ray Fluorescence of Diverse Fossils From Multiple Konservat-lagerstätten, Extant Organisms, and Artificial Maturation Experiments

This study utilizes synchrotron X-ray fluorescence to demonstrate that fossil elemental compositions are primarily driven by diagenetic processes and sediment interaction rather than original tissue chemistry, indicating that most detected elemental signatures are exogenous and that attempts to identify tissue-specific markers must strictly control for geologic formation.

Hydrocarbon Lease Overlap with Small Cetacean Habitat: A Reproducible GIS Comparison of Rice's Whale and the Cook Inlet Beluga Whale

This study utilizes reproducible GIS analysis of public data to demonstrate that active hydrocarbon leases overlap significantly more with the Cook Inlet beluga whale's critical habitat than with Rice's whale's, while highlighting that the magnitude of overlap for Rice's whale is highly sensitive to the choice of habitat boundary used in the analysis.

Seasonal Dynamics of Heavy Metal Contamination and Associated Health Risk Assessment in the Water Resources of Riruwai Mining Area, North-Western Nigeria

This study assessed seasonal heavy metal contamination in the water resources of Nigeria's Riruwai mining area, finding that while concentrations were higher during the rainy season and exceeded regulatory limits in some samples, the associated non-cancer and cancer health risks for both adults and children remained within acceptable thresholds, though children were identified as more vulnerable.

Spatial Dynamics and Socioeconomic Drivers of Urban Household Mini-Grids in Lubumbashi, DR Congo

This study analyzes a 2024–2025 survey of 5,270 households in Lubumbashi, DR Congo, revealing that privately operated urban mini-grids serve over 20% of residents primarily due to public grid unreliability rather than lack of access, with participation driven by income diversification and education rather than household income alone.

Quasi-global, land-only, high-resolution and spatially averaged climate variables from downscaled CMIP6 models for climate impact research

This paper presents a quasi-global, high-resolution dataset of daily, land-only climate variables for 1985–2100, generated by applying the DBCCA method to six CMIP6 models under two emission scenarios, and provides both 0.1° gridded outputs and population-weighted administrative-level aggregates specifically designed to support tropical health-related impact research and policy planning.

Municipal heat stress and respiratory mortality in Central Brazil assessed by an integrated environmental vulnerability index

This study demonstrates that an integrated Urban Heat Stress Index, which combines climatic exposure with environmental buffering capacity, effectively identifies municipalities in Central Brazil with significantly higher respiratory mortality risks, offering a practical tool for targeted public health planning and climate adaptation.
