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).

A Parametric Study of Solar Wind Properties and Composition Using Fluid and Kinetic Solar Wind Models

The Astrophysical Journal
The physical processes in the solar corona that shape the solar wind remain an active research topic. Modeling efforts have shown that energy and plasma exchanges near the transition region play a crucial role in modulating solar wind properties ...

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.

Power-law Indices of EUV Intensity Power Spectrum in Flaring Coronal Active Regions

The Astrophysical Journal
Solar intensity power spectra are usually characterized by colored noise, with the spectral energy following a segmented power-law function of frequency, S ( f ) ∝ f ^− ^α , over different frequency ranges. Typically, the power-law index exceeds 1 in the

Spectral analysis of 3D MHD models of coronal structures

, 2009
We study extreme-ultraviolet emission line spectra derived from three-dimensional magnetohydrodynamic models of structures in the corona. In order to investigate the effects of increased magnetic activity at photospheric levels in a numerical experiment,

Localized Heating and Dynamics of the Solar Corona due to a Symbiosis of Waves and Reconnection

The Astrophysical Journal
The Sun’s outer atmosphere, the corona, is maintained at mega-Kelvin temperatures and fills the heliosphere with a supersonic outflowing wind. The dissipation of magnetic waves and direct electric currents are likely to be the most significant processes ...

Measurements of Photospheric and Chromospheric Magnetic Fields

, 2015
The Sun is replete with magnetic fields, with sunspots, pores and plage regions being their most prominent representatives on the solar surface. But even far away from these active regions, magnetic fields are ubiquitous.

Exploring the impact of Cabotegravir‐Rilpivirine long‐acting on weight gain, body composition and quality of life in adults living with HIV

HIV Medicine, Volume 27, Issue 5, Page 727-739, May 2026.
Abstract Introduction Long‐acting injectable antiretroviral therapy (ART) with Cabotegravir (CAB) and Rilpivirine (RPV) offers an alternative to daily oral regimens, improving adherence and patient satisfaction. However, its impact on body composition and metabolism remains underexplored.

Magnetic Field Variability as a Consistent Predictor of Solar Flares

The Astrophysical Journal
Solar flares are intense bursts of electromagnetic radiation that occur due to a rapid destabilization and reconnection of the magnetic field. While preflare signatures and trends have been investigated from magnetic observations prior to flares for ...
