A Crazy Idea: Ibn Sīnā on Hylomorphism, the Elements, Mixture and Evolutionary Processes
Theoria, EarlyView.ABSTRACT Ibn Sīnā (c. 973‐1037), the Avicenna of Latin fame, developed a unique theory of the elements and their status in mixtures that severely challenged the views of earlier natural philosophers and in its turn was severely challenged by later Latin Schoolmen in the West.

Analytical Science Advances, Volume 7, Issue 2, December 2026.The pharmacological potential of the methanolic stem extract of Acampe papillosa is evaluated using in vivo and in silico approaches. The extract demonstrates significant anxiolytic, sedative, anti‐inflammatory, and antipyretic activities in experimental models, while molecular docking supports the observed biological effects through favorable ...

Motion Sensitivity Analysis and Terrain Correction for UAV‐Borne Gamma‐Ray Spectrometry
Geophysical Prospecting, Volume 74, Issue 7, September 2026.ABSTRACT Uncrewed aerial vehicles (UAVs) equipped with gamma‐ray spectrometry sensors enable high‐resolution surveys but face challenges in rugged terrain. Conventional airborne gamma‐ray processing commonly approximates the source–detector geometry using a single height‐above‐ground parameter.

Tracing Continental Basalt Sources and Mantle Processes Using Fe Stable Isotopes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract Iron (Fe) isotopes have emerged as powerful tracers of mantle source heterogeneity and melting processes, yet the mechanisms producing heavy Fe isotope signatures (high δ57Fe values) in intraplate basalts remain debated. Competing interpretations include partial melting of recycled pyroxenite domains versus carbonate‐induced oxidation of a ...
