Nature, origin, and phosphorylation potential of the phosphorus/sulfur‐bearing nanoscale multiphasic assemblages in the CM chondrites Murchison and Murray

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2303-2335, September 2026.
Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2233-2257, September 2026.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Access to Essential Services: A Critical Factor for Predicting Recovery and Quantifying Resilience

open access: yesRisk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT Essential services are necessary for individuals to recover from and adapt to disruptive events, yet the relationship between access to such services and recovery trajectory is poorly understood. Data on household recovery times are typically only available through surveys, which are limited in scale and scope. Further, the availability of all

Variations of Mid‐Magnetotail Magnetic Pressure During Substorms

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Magnetic reconnection is commonly observed in the mid‐tail plasma sheet during substorms, the mechanism behind this spatial preference, however, remains unsolved. This study focuses on magnetic pressure evolution within this critical region during substorms.

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at ∼0.1 ${\sim} 0.1$–10 keV is traditionally considered the main driver of auroral emissions, recent studies show that >30 ${ >} 30$ keV electrons and protons can significantly ...

Post‐Sunset Merging of Equatorial Ionization Anomaly Crests Into a Single Peak Over ∼35° Longitude During the 19 January 2026 Geomagnetic Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We investigate the nighttime equatorial ionosphere during the 19 January 2026 geomagnetic storm using Global‐scale Observations of the Limb and Disk OI 135.6 nm observations and ground‐based GPS Total Electron Content. The observations reveal a pronounced longitudinal asymmetry in the post‐sunset equatorial ionization anomaly (EIA).
