Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...

Integrative Phytochemical, Antioxidant, and NLRP3‐Linked and Anti‐Inflammatory Evaluation of Salvia balansae (Aurès Chemotype): Insights Into Its Safety and Therapeutic Potential

open access: yesChemistryOpen, Volume 15, Issue 9, September 2026.
An endemic Aurès chemotype of Salvia balansae emerges as a rich source of luteolin, rosmarinic acid, and other polyphenols with potent antioxidant and NLRP3‐linked anti‐inflammatory activities. Protection against experimental inflammation, favorable enzyme‐modulating properties, and a wide safety margin highlight its promise as a pharmaceutical and ...

Preserved Through Hyperaridity, 150 Million Years of Exhumation and Strike‐Slip Deformation in the Atacama Coastal Cordillera

open access: yesTectonics, Volume 45, Issue 9, September 2026.
Abstract The Coastal Cordillera of northern Chile, in the forearc of the Andean subduction zone, provides an ideal site to evaluate exhumation above the oldest active subduction under extreme aridity. This range lies parallel to a sediment‐starved trench, has experienced hyperaridity since the Miocene, and is transected by the ∼1,000‐km‐long Atacama ...

Motion Sensitivity Analysis and Terrain Correction for UAV‐Borne Gamma‐Ray Spectrometry

open access: yesGeophysical 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.

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Herba Lysimachiae Polysaccharide‐Modified Selenium Nanoparticles Alleviate Oxidative Injury in Kidney Stones via TOMM22‐Regulated Mitophagy Activation

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
HLP‐SeNPs, a Lysimachia christinae polysaccharide‐modified selenium nanoparticle, treat kidney stones by downregulating TOMM22 expression, which reduces PINK1 translocation into mitochondria and promotes its retention on the outer mitochondrial membrane.

Functional and Taxonomic Structuring of Ground‐Dwelling Spider Communities Under the Combined Effects of the Environment and Metal Contamination

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Through a field study along a metal contamination gradient, we propose a combined application of taxonomic and functional approaches to study the impacts of contamination on polyphagous predators, spiders. We have demonstrated a significant impact of metal contamination on spider communities, although it operates among a set of variables (e.g ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, Volume 61, Issue 8, Page 2258-2278, August 2026.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.
