Raw material procurement in northwest Sierra Morena during the Middle Palaeolithic: quartz exploitation at La Sima Cave (Constantina, Seville, SW Spain)

This study characterizes Middle Palaeolithic lithic procurement at La Sima Cave in SW Spain through geological mapping and microscopic analysis, revealing that human groups employed a dual mobility strategy utilizing nearby quartz outcrops (<10 km) and more distant Guadalquivir River terraces (25–30 km) for higher-quality quartzite and chert.

Wetland tree stem methane emissions are fuelled by modern carbon sources

This study demonstrates that methane emissions from wetland tree stems are primarily fueled by modern carbon derived from shallow soil organic matter and plant-driven cycling, rather than ancient carbon stores or in-stem production.

Geomagnetic reversals are modulated by the motion of basal mantle structures

This study establishes a quantitative link between geomagnetic reversal frequencies and the equatorial extent of basal mantle structures, demonstrating that changes in short-wavelength core-mantle boundary heat flux heterogeneities drive variations in the Earth's magnetic field polarity.

Eddy-edge submesoscale dynamics drive chlorophyll exchange across the mixed-layer base

This study demonstrates that eddy-edge fronts, rather than eddy cores, drive localized bidirectional chlorophyll exchange across the mixed-layer base in the Antarctic Circumpolar Current, fundamentally revising the conventional understanding of mesoscale biogeochemical transport.

Earth ecosystem models use wrong temperature sensitivity index (Q10) to predict Antarctic phytoplankton growth

The paper argues that Antarctic phytoplankton growth has a much higher temperature sensitivity (Q10 of 8.85) than currently modeled, implying that future warming will significantly boost Southern Ocean primary production and carbon drawdown if this parameter is corrected.

Twenty Years of Aerosol Optical Depth over Cairo, Egypt (2005–2025): A Comprehensive Climatology Using AERONET and MODIS Observations

This study presents the first unified 20-year (2005–2025) aerosol climatology for Cairo, Egypt, utilizing AERONET and MODIS data to reveal a statistically significant decreasing trend in aerosol optical depth while characterizing distinct seasonal regimes driven by Khamaseen dust and agricultural burning.

Evidence-Efficient Isotope Hydrology for Groundwater Management in Data-Scarce Aquifers: A Legacy-Data Reassessment from Palestine

This paper presents an evidence-efficient isotope-hydrology framework that transforms a historical archive of 176 legacy observations from the West Bank into actionable management insights for groundwater recharge, renewability, and pollution source attribution in data-scarce, transboundary aquifers.
