Comparison of tomographic wind retrievals with different geometric implementations for multistatic meteor radar networks

A growing number of multistatic meteor radar networks are being established worldwide. The multistatic geometry with overlapping observation volumes of several meteor radars or passive receivers permits the inference of higher-order kinematic properties of the wind field or even...

A First Global Full-vector Coronal Magnetic Field Inference Using MLSO CoMP and UCoMP Observations

Abstract Building on recent advances in coronal spectropolarimetry, seismology, and magnetic-field inferences of Z. Yang et al. (2024) and A. R. Paraschiv (2026), we present the first application of the CLEDB IQUD inversion methodology to Mauna Loa Solar Observatory CoMP and UCoM...

The May 2024 Storm: The Cusps and Dayside Magnetopause in Simulated Soft X‐Rays

Abstract The coronal mass ejection (CME) arriving at Earth on 10 May 2024 caused the most intense geomagnetic storm in the last two decades, resulting in highly unusual cusp and magnetopause dynamics. We simulate soft X‐Ray emission due to solar wind charge exchange with exospher...

Efficient and Long‐Lasting Seawater Oxidation Over a Sodium Nitroprusside‑Modified NiFe Layered Double Hydroxide

ABSTRACT Despite the great potential of direct seawater electrolysis technology in alleviating freshwater scarcity for green hydrogen production, its practical application is severely limited by the degradation of anode catalysts under chloride‑rich conditions. In this study, we...

Long‐Term Increase in Equatorial Rayleigh‐Taylor Instability: Synergistic Effects of Greenhouse Gas Cooling and Geomagnetic Field Secular Variation

Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations. Results reveal a...

Cholesterol sulfate as a novel theranostic target for sepsis-induced liver injury through Beclin1-mediated autophagy enhancement and pyroptosis suppression

Sepsis remains a life-threatening syndrome, and septic liver injury is a frequent and critical complication for which no specific pharmacological therapy exists. Current biomarkers lack sufficient specificity for early diagnosis and severity assessment, highlighting an urgent nee...

OAF Blocks SIAH1‐Mediated Degradation of SCPX, a Therapeutic Strategy for MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) poses an increasing threat to global public health. Currently approved drugs for MASLD, such as resmetirom and semaglutide, have demonstrated clinical efficacy. However, their use is associated with notable adverse...
