Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Role of Large‐Scale Traveling Ionospheric Disturbances in the Positive Storm Phase Observed by the Millstone Hill Radar and GNSS TEC Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A moderate geomagnetic storm was driven by high‐speed solar wind stream on 14 March 2016. We show that large‐scale traveling ionospheric disturbances (LSTIDs) played a significant role in producing the ionospheric storm positive phase at mid‐latitudes in the North American sector.

The Role of High‐Gradient Diffusion Nuclear Magnetic Resonance in Exploring Peculiarity of Water in Ionic Liquids Doped with Alkali Metals

Chemistry–Methods, Volume 5, Issue 12, November 2025.
Applying high gradients during diffusion nuclear magnetic resonance experiments allows for the determination of isolated microenvironments in ternary solutions composed of an imidazolium‐based ionic liquid, water and alkali metal halide. Two separate water populations are detected, forming either the isolated solvent network or the first solvation ...

Timescales of Asymmetries in Magnetospheric Dynamics Induced by the IMF By Component

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract Recent studies have shown that global geomagnetic activity and particle precipitation are enhanced, when the dawn‐dusk By $\left({B}_{y}\right)$ component of the interplanetary magnetic field (IMF) and Earth's magnetic dipole tilt angle Ψ ${\Psi }$ have opposite signs.

Characteristics of Atmospheric Gravity Waves and Medium Scale Traveling Ionospheric Disturbances Derived From EISCAT Measurements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract This study investigates the characteristics of medium scale traveling ionospheric disturbances (MSTIDs) relative amplitudes (δNe/Ne $\delta Ne/Ne$) in the ionospheric E to lower F regions, using the EISCAT VHF radar data measured from 41 daytime runs in years 2008–2024 carried out mostly between 7−13 $7-13$ UT.

Decades of Change in Vascular Plant Composition in High‐Latitude Ecosystems: Shifting Prevalence of Pollination Strategies

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We studied long‐term changes in plant species that require or support pollinators in comparison to those that do not interact with pollinators in two high‐latitude ecosystems of northern Fennoscandia. Over the past 50 years, plant communities in tundra and boreal herb‐rich forests have shifted toward reduced dependence on insect pollination, with ...
