Investigating Potential Benefits of Future Sub‐L1 Missions With STEREO‐A

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO‐A spacecraft as a sub‐L1 monitor. Between November 2022 and June 2024, STEREO‐A crossed the Sun–Earth line, covering longitudinal and radial separations of ±15° $\pm 15{}^{\circ}$ from the Sun–Earth line and 0.01–0.06 au from Earth.

Three-dimensional Global Hybrid Simulation of Magnetosheath Jets at Mercury

The Astrophysical Journal Letters
Plasma high-speed jets are common in Earth’s magnetosheath, and they significantly perturb the magnetosheath and affect the magnetosphere. The space environment of Mercury, characterized by the bow shock, magnetosheath, and magnetosphere, shares many ...

Comprehensive Validation of Novel Deep Learning Architectures to Forecast Geomagnetic Substorms

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Magnetic substorms are disturbances in the terrestrial magnetosphere that can have significant space weather impacts, although forecasting their onset accurately remains an open problem. In this study, we develop multiple novel machine learning architectures based on convolutional neural networks, long short‐term memory networks, extreme ...

The multiple dimensions of intraspecific variation in seed dispersal

Functional Ecology, Volume 40, Issue 6, Page 1822-1835, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal plays a central role in plant ecology and evolution, and understanding its variation is key to predicting species demography and range dynamics. However, dispersal is difficult to measure, and most modelling and field studies assume uniform dispersal ...

60Fe-60Ni chronology of core formation in Mars

, 2014
The timescales of accretion, core formation, and magmatic differentiation in planetary bodies can be constrained using extinct radionuclide systems. Experiments have shown that Ni becomes more siderophile with decreasing pressure, which is reflected in ...

Investigation on Upstream Ion Events from the L1 Point Observation: New Insights

The Astrophysical Journal
There has been long-standing controversy regarding the origin and transport of short-lived energetic ion events observed upstream of the Earth’s bow shock. In this work, by adopting a unique method, we study the characteristics of 152 upstream ion events

Cessation of Gene Flow Associated With the Reduction of a Sexually Selected Phenotype in the Island Stag Beetle

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Whether gene flow acts as a creative or constraining force on local adaptation is a fundamental question in evolutionary biology, yet its role in the evolution of sexually selected traits remains poorly understood. Here we combine whole‐genome and functional analyses to investigate how geological isolation is associated with the evolution of ...

“Good job reporting this!”: Examining psychological needs and community building in YouTube conspiracy narratives

Political Psychology, Volume 47, Issue 3, June 2026.
Abstract The proliferation of conspiracy theories online has tangible offline consequences, both on an individual and collective level. Conspiracy narratives have been associated with reduced belief in democracy, the rise of populist parties, and can act as a radicalization multiplier in such contexts.

Electron Acceleration in Magnetic Islands in Quasi-parallel Shocks

The Astrophysical Journal
We report new theories and simulations for electron acceleration in magnetic islands generated by magnetic reconnection in the shock turbulence in a quasi-parallel shock, using a 2 and 1/2 dimensional particle-in-cell simulation. When an island is moving,
