Quantified Plasma Heating and Energy Dissipation in the Earth’s Quasi-perpendicular Bow Shock

The Astrophysical Journal
The high-speed solar wind decelerates as it travels through the Earth’s bow shock, during which a portion of the incident flow energy is converted into the plasma thermal energy. However, the energy partition of plasma heating among different species, as

Properties of Electron-scale Magnetic Reconnection at a Quasi-perpendicular Shock

The Astrophysical Journal, 2023
Recent spacecraft observations have shown that magnetic reconnection occurs commonly in turbulent environments at shocks. At quasi-perpendicular shocks, magnetic field lines are bent by the back-streaming reflected ions, which form a current sheet in the

Identifying MESSENGER Magnetospheric Boundary Crossings Using a Random Forest Region Classifier

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract We present a new list of bow shock and magnetopause crossings based on automated region classification for the MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging) mission. We fit a random forest model to magnetometer and ephemeris data to classify the solar wind, magnetosheath, and magnetosphere regions surrounding Mercury.

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

MMS Observations of the Velocity-space Signature of Shock-drift Acceleration

The Astrophysical Journal Letters
Collisionless shocks play a key role in the heliosphere at planetary bow shocks by governing the conversion of the upstream bulk kinetic energy of the solar wind flow to other forms of energy in the downstream, including heating of the plasma species ...

Removal of Transgenes and Evaluation of Yield Penalties in Genome Edited Bacterial Blight Resistant Rice Varieties

Plant Biotechnology Journal, Volume 24, Issue 2, Page 939-953, February 2026.
ABSTRACT Bacterial blight (BB) of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the major drivers of yield losses in Africa and Asia. Xoo secretes TAL‐effectors (TALe) that induce host SWEET sucrose uniporter by binding to the effector binding element (EBE) of SWEET promoters, likely required for Xoo reproduction and virulence.

A 3D Parametric Venusian Bow Shock Model with the Effects of Mach Number and Interplanetary Magnetic Field

The Astronomical Journal
Using global magnetohydrodynamics simulations, we have developed a three-dimensional parametric model for the Venusian bow shock based on a generalized conic section function defined by six parameters, with the effects of the solar wind magnetosonic Mach

MsWRKY49 Modulates Pollen Tube Elongation in Response to Boron Deficiency by Regulating Reactive Oxygen Species Homeostasis in Alfalfa

Plant Biotechnology Journal, Volume 24, Issue 2, Page 856-870, February 2026.
ABSTRACT Boron, an essential micronutrient, plays a crucial role in plant reproductive processes. Boron deficiency is widespread in many regions and significantly reduces alfalfa (Medicago sativa) seed yield, yet the molecular mechanisms underlying its impact on reproductive organ development remain elusive.

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...
