Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Coronal "Wave": Magnetic Footprint of a Coronal Mass Ejection?

open access: yesThe Astrophysical Journal, 2007
We investigate the properties of two "classical" EUV Imaging Telescope (EIT) coronal waves. The two source regions of the associated coronal mass ejections (CMEs) possess opposite helicities, and the coronal waves display rotations in opposite senses.

Hemispheric Distribution of Halo Coronal Mass Ejection Source Locations

open access: yesThe Astrophysical Journal
The hemispheric asymmetry of solar activity is one of the essential physical consequences of the interior dynamo process. However, the hemispheric distribution of halo coronal mass ejection (HCME) source locations has not been investigated in detail ...

Suspected Mesenteric Malperfusion in Acute Type A Aortic Dissection During Pregnancy: A Case Report and Review of Reperfusion‐First Strategies

open access: yesClinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT Aortic dissection during pregnancy is rare but potentially catastrophic. Acute Type A aortic dissection generally requires urgent surgical repair. When visceral malperfusion is present, however, the optimal sequence of interventions may be complex, particularly when pregnancy and recent cesarean delivery increase operative risk.

Dynamic disappearance of prominences and their geoeffectiveness [PDF]

open access: yesGeofísica Internacional, 2008
We study 14 cases of dynamic “disparition brusque” (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994.

Gastrodia elata Polysaccharide Attenuates Aging by Modulating Oxidative Stress, Inflammation, and Gut Microbiota

open access: yesFood Science &Nutrition, Volume 14, Issue 10, October 2026.
Gastrodia elata polysaccharide (GEP) alleviates aging in mice by activating the Nrf2/Keap1 antioxidant signaling, inhibiting the TLR4/NF‐κB‐driven neuroinflammation, remodeling gut microbiota, and restoring intestinal‐barrier integrity. Synergistic regulation of oxidation, inflammation, and gut homeostasis underpins its anti‐aging potential for ...

The DIRECD Coronal Mass Ejection Direction Catalog: Three-dimensional Propagation Inferred from Coronal Dimmings

open access: yesThe Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are among the primary drivers of space weather disturbances at Earth, yet their early propagation in the low corona remains poorly constrained owing to occultation and projection effects inherent to coronagraph observations.

Assessing the Economic Benefits of Space Weather Mitigation Investment Decisions: Evidence From Aotearoa New Zealand

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather events pose a growing threat to modern economies, yet their macroeconomic consequences remain underexplored. This study presents the first dedicated economic assessment of geomagnetic storm impacts on Aotearoa New Zealand, quantifying potential gross domestic product (GDP) losses across seven conservative disruption and ...

Schumann Resonance Frequency Increase Following Recurrent Solar Wind Stream Onsets

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null ...

Global Three‐Dimensional Simulation of Magnetospheric Dynamics During the Extreme Geomagnetic Storm of 10–11 May 2024

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study presents a high‐resolution three‐dimensional global magnetohydrodynamic (MHD) simulation of the historic geomagnetic storm of 10–11 May 2024, using observational data for the ACE solar wind input. This extreme event was characterized by intense solar wind dynamic pressure (∼50 nPa) and exceptionally strong interplanetary magnetic ...
