Three-Dimensional P- and S-Wave Local Earthquake Tomography of the Eastern Alborz, Northern Iran

This study utilizes 3D P- and S-wave local earthquake tomography to reveal pronounced crustal heterogeneity and concealed fault structures in the eastern Alborz, demonstrating that active deformation is localized within mechanically heterogeneous domains and providing a refined geophysical framework for seismic hazard assessment in the Arabia–Eurasia collision zone.

Environmental Suitability Reveals Under-Surveyed Refugia for Endemic Damselflies in an Afromontane Region

By integrating ensemble species distribution modeling with historical sampling data, this study identifies significant under-surveyed high-elevation refugia for threatened endemic damselflies in Zimbabwe's Eastern Highlands, suggesting that their apparent rarity often reflects sampling gaps rather than true absence and providing a framework to prioritize future conservation surveys.

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.
