Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.

Membrane lipid composition modulates the organization of VDAC1, a mitochondrial gatekeeper
Communications BiologyVDACs, the most abundant proteins in the outer mitochondrial membrane (MOM), are crucial for mitochondrial physiology. VDAC regulate metabolite and ion exchange, modulate calcium homeostasis, and play roles in numerous cellular events such as apoptosis ...

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data
AGU Advances, Volume 7, Issue 6, September 2026.Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

Understanding mechanisms underlying solar cycle predictability with a general framework
Astronomy & AstrophysicsContext. The large-scale magnetic field observed at the solar surface is produced by the interior dynamo process. Whether this surface field also provides the dominant seed for the subsequent dynamo cycle, however, remains controversial, with important ...

Feasibility of a magma ocean dynamo on Mars
Progress in Earth and Planetary Science, 2017 Crustal magnetization of rocks in regions of Mars surface testifies to an era of dynamo activity. I examine the possibility that the dynamo that operated then, in the first 400–600 Ma after Mars formed, was powered by a crystallizing subsurface magma ...

Establishing a Lunar Origin for Paleomagnetic Records in Apollo Samples
Geophysical Research Letters, 2023 Numerous paleomagnetic studies attribute the magnetization preserved within Apollo samples to an ancient dynamo. However, other works propose that lunar rocks were instead magnetized by either transient impact‐related magnetic fields on the Moon or by ...

Quasi 6‐Day Wave Variability in the Thermosphere and Ionosphere: Observations and Modeling
Earth and Space Science, Volume 13, Issue 9, September 2026.Abstract Satellite observations of the upper mesosphere and lower thermosphere from TIMED‐SABER and ICON‐MIGHTI reveal a clear Quasi 6‐Day Wave (Q6DW) event in the winds and temperatures in this region. This Q6DW event persists across multiple data sets throughout the middle‐to‐upper thermosphere and the F‐region ionosphere, including GOLD disk ...
