Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Tectonic Influences on Trench Slope Basin Development via Structural Restoration Along the Outer Nankai Accretionary Prism, Southwest Japan

Geochemistry, Geophysics, Geosystems, 2020
Three‐dimensional (3‐D) seismic reflection data and sediment cores record ~2.87 million years of structural and depositional history of a trench slope basin along the outer Nankai accretionary prism, southwest Japan.

Rheology and Structure of Fe‐Mg‐Ca Enriched Silicate Melt: Benchmarking Viscosity Models for an Exotic Planetary Composition

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Silicate melt viscosity plays a pivotal role in the evolution of rocky bodies within the Solar System, exerting first‐order control on mantle differentiation and stratification, while dictating the metal‐silicate separation and the subsequent volcanic activity.

MUD DIAPIRS OF THE MEDITERRANEAN RIDGE: SEDIMENTOLOGICAL AND MICROPALEONTOLOGICAL STUDY OF THE MUD BRECCIA

Rivista Italiana di Paleontologia e Stratigrafia, 2017
Two recent sea-going expeditions showed that mud diapirism is a common feature in the accretionary wedge of the Mediterranean Ridge, but unlike in other prisms, it is well expressed exclusively in the most elevated areas of the Ridge.

Mineralogy, mineral chemistry, and redox equilibria in ten aggregate particles from asteroid Bennu

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1905-1927, August 2026.
Abstract Examination of 10 Bennu aggregate particles has revealed the presence of many phases which taken together can provide constraints on the oxygen fugacity (fO2) of Bennu samples. Phyllosilicates (saponite and serpentine), carbonates, oxides (magnetite, chromite), sulfides (pyrrhotite, pentlandite), phosphate (hydroxyapatite, Na‐Mg‐phosphate ...

Attenuation of Tau Hyperphosphorylation by Chronic Toxoplasma gondii Infection in a Mouse Model of Alzheimer's Disease

Parasite Immunology, Volume 48, Issue 8, August 2026.
ABSTRACT Alzheimer's disease (AD) is characterized by amyloid‐β (Aβ) peptide accumulation and tau protein‐mediated neurodegeneration, and neuroinflammation is increasingly recognized as a major process associated with tau pathology. Chronic Toxoplasma gondii infection reduces amyloid accumulation in AD models through immune modulation, but its stage ...

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

Sedimentology, Volume 73, Issue 5, Page 1842-1866, August 2026.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Divergent skeletal muscle metabolite exchange in insulin‐like growth factor‐1‐stimulated myotubes and resistance‐exercised human muscle

Experimental Physiology, Volume 111, Issue 8, Page 3784-3799, 1 August 2026.
Abstract Skeletal muscle hypertrophy requires a substantial nutrient influx for biomass accretion, but global metabolite exchange during growth is poorly characterized. Therefore, we profiled the metabolite uptake and release in insulin‐like growth factor‐1 (IGF‐1)‐stimulated C2C12 myotubes and human muscle 24 h after resistance exercise ...
