Measurements of Coronal Faraday Rotation at 4.6 Solar Radii

, 2014
Many competing models for the coronal heating and acceleration mechanisms of the high-speed solar wind depend on the solar magnetic field and plasma structure in the corona within heliocentric distances of $5R_\odot$.

Understanding the Evidence Gaps: Diets and Fruit and Vegetable Intake Across Five Diverse Low‐ and Middle‐Income Countries

Maternal &Child Nutrition, EarlyView.
This perspective article synthesizes findings from scoping reviews examining diet and F&V intake, and interventions to increase F&V consumption among population groups in five countries: Benin, Fiji, the Philippines, Sri Lanka and Tanzania. ABSTRACT Poor dietary quality, particularly inadequate fruit and vegetable (F&V) intake, remains a significant ...

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Coupling the solar surface and the corona: coronal rotation, Alfv\'en wave-driven polar plumes

, 2013
The dynamical response of the solar corona to surface and sub-surface perturbations depends on the chromospheric stratification, and specifically on how efficiently these layers reflect or transmit incoming Alfv\'en waves.

Machine Learning for Local Detection of Separators in Three‐Dimensional Magnetic Fields

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Magnetic reconnection is a major plasma phenomenon occurring in various key environments ranging from the Sun and near‐Earth space to astrophysical plasmas. While magnetic reconnection is relatively well‐understood under two‐dimensional (2D) settings, it remains challenging to characterize in three‐dimensional (3D) magnetic fields.

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Imaging the Solar Corona from “Within”: A Cutting-edge Approach to Enhance PSP/WISPR Imagery

The Astrophysical Journal Supplement Series
The unprecedented remote-sensing observations obtained by the Wide Field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) from distances inside Mercury’s orbit are revolutionizing our perception of the fine-scale morphology and ...

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.
