Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

The Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...

Drillability evaluation and spatial distribution characteristics of Fengcheng Formation shale in Mahu Sag

Thermal Science
This study investigates rock drillability characteristics and spatial distribution patterns to optimize drilling efficiency. Laboratory testing of core samples from six wells provided comprehensive mechanical data, including uniaxial compressive strength (147.81-306.82 MPa), triaxial compressive strength (310.56-785.00 MPa), and drillability indices (6.

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

Ganoderic Acids Alleviate Neuroinflammation by Targeting Myeloid Differentiation Factor 2 for Ischemic Stroke Therapy

Exploration, Volume 6, Issue 1, February 2026.
Ganoderic acids confer neuroprotection in ischemic stroke by directly targeting MD2, thereby blocking MD2/TLR4 complex formation and downstream MAPK and NF‐κB activation. This suppresses microglia‐driven neuroinflammation and mitigates cerebral ischemic injury.
