Geopolitical Energy Shock Triggers Rural Aerosol Resurgence — Evidence from India’s 2026 LPG Crisis

India's 2026 LPG crisis, triggered by geopolitical energy shocks, forced reverse migration to rural Bihar and eastern Uttar Pradesh, where unaffordable fuel costs drove households back to solid-fuel combustion, significantly increasing local aerosol pollution and exposing a critical structural vulnerability in the nation's clean-cooking transition that prioritizes access over supply security.

Millennial-scale ice retreat after the first Phanerozoic glaciation

This study reveals that the post-glacial recovery following the Late Ordovician Hirnantian glaciation was marked by seven millennial-scale cold–warm cycles driven by episodic ice-sheet discharge, demonstrating that such climate instability is a fundamental feature of Earth's history that significantly influenced early biotic recovery patterns.

A Relationship Between Baroclinic Tidal and Wave Horizontal Spectral Energy and Stratification on the Australian Continental Shelf

This study analyzes temperature and velocity data from Australian moorings to establish a power-law relationship between upper-ocean stratification and baroclinic wave energy that holds for specific depth and temperature difference thresholds, offering a cost-effective method to predict internal wave energy fields and mixing potential.

Geochemical modelling of ore-forming processes in the Börzsöny Mountains, N-Hungary

This study utilizes PHREEQC 3.0 geochemical modeling to demonstrate that the reduced porphyry mineralization in the central Börzsöny Mountains resulted from multiple fluid pulses characterized by fluctuating temperature, redox conditions, and sulfur fugacity, which successfully constrained the observed paragenetic sequence of sulfide precipitation and alteration.

Institutional network connectivity outweighs land-use zoning in shaping watershed sustainability: a participatory agent-based model in the Colombian Andes

This study utilizes a participatory agent-based model in the Colombian Andes to demonstrate that strengthening institutional network connectivity is more effective for watershed sustainability and forest conservation than relying solely on formal land-use zoning, while also revealing that labor availability, rather than income or environmental values, primarily drives smallholders' willingness to participate in conservation.

Parasitic Helminths (Trematoda, Nematoda, Cestoda) as Bioindicators of Heavy Metal Pollution in Marine Ecosystems: A Comparative Study on Saurida undosquamis

This study demonstrates that parasitic helminths (specifically Trematoda and Cestoda) isolated from the Brushtooth lizardfish (*Saurida undosquamis*) along the Misurata coast of Libya serve as sensitive and reliable bioindicators for monitoring heavy metal pollution, particularly showing higher accumulation of toxic metals like Cadmium and Lead during the cold season.
