Salt Chemistry Regulates Habitable Microenvironments in Brinicles: Implications for Icy Ocean Worlds

This study demonstrates that brine chemistry fundamentally dictates the microstructure of brinicles and the spatial distribution of cellular proxies, revealing that calcium chloride promotes localized entrapment near the inner channel while sodium chloride enables uniform distribution, thereby highlighting the critical role of ocean composition in assessing habitability on icy ocean worlds.

Evidence for lower soil carbon storage in forests invaded by Chinese privet

This study demonstrates that Chinese privet invasion in southeastern US forests significantly reduces both soil organic carbon and tree biomass carbon by over 40% compared to uninvaded areas, highlighting the critical need for invasive species management to preserve carbon sequestration in temperate forests.

Flow Profiling of a Geothermal Well Using an Isotherm-Slope Method Applied to Fiber-Optic Distributed Temperature Sensing Data: An Example from Utah FORGE EGS Well 16B(78)-32

This paper introduces and validates an isotherm-slope method that utilizes fiber-optic distributed temperature sensing (DTS) data to estimate wellbore flow profiles and stage-scale partitioning in enhanced geothermal systems without requiring repeated logging interventions or calibrated thermal properties.

Mitigation Technologies for Wellbore Blockage Caused by Coal Powder Ejection from Surface Wells in Mining-Disturbed Areas: A Case Study

This paper investigates wellbore blockage caused by coal powder ejection in mining-disturbed surface wells and demonstrates that while high-pressure gas flushing and standpipes have limited effectiveness, installing a 1.0 mm metal mesh filter around the slotted pipe successfully mitigates plugging while maintaining high gas drainage efficiency.

Bridging the Gap: Assessing China’s Adaptation Policies in a Multi-Hazard Climate Risk Context

This study evaluates China's 19 national-level adaptation policies (2007–2024) using a multi-hazard risk framework, revealing that while objective setting is strong, overall policy quality remains low due to significant gaps in resource capacity and decision-making, though a statistically significant improvement has emerged since 2015.

Super-Resolution of Radar/Rain Gauge–Analyzed Precipitation Using Gaussian Process Regression with a Steering Kernel

This study demonstrates that applying Super-Resolution Gaussian Process Regression with a Steering Kernel (SRGP-SK) to radar/rain gauge–analyzed precipitation effectively reconstructs finer convective structures and achieves higher structural similarity and spectral resolution compared to both standard SRGP and bicubic interpolation, though further validation across more cases is needed for broader application.

The tsunami triggered by the 24 June 2026 Venezuela earthquakes: tectonic context and tsunami modelling

This paper analyzes the June 24, 2026, Venezuela earthquake and its resulting tsunami by demonstrating that while finite-fault numerical models successfully reproduce regional waveforms, the significant discrepancy between simulated and observed local amplitudes suggests that factors such as coastal effects, grid resolution limits, or a submarine landslide likely contributed to the event's intensity.
