Nakhlite Emplacement as Constrained by X‐Ray Computed Tomography and 3D Quantitative Textural and Petrofabric Analyses

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Nakhlites, clinopyroxene‐rich rocks, are the largest single‐origin suite of samples from Mars. Despite extensive study to discern their petrogenetic histories, nakhlite emplacement mechanisms and environments are not well‐constrained, and it is unknown whether they represent intrusive or extrusive igneous rocks, or a combination.

Approximation of Daily AMS‐02 Spectra With Machine Learning Methods

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

New Li Lidar Observations and Model Simulations: A Window to Anthropogenic Signatures

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We present Li lidar observations in the mesopause region above Kühlungsborn, Germany (54°N, 12°E). The lithium layer is mainly formed by meteoric ablation. But lithium has a much higher relative abundance in space debris compared with meteoroids, making it a good indicator of anthropogenic influence in the upper mesosphere.

Simulated Characteristics of On‐Ground Gamma‐Ray Glows

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 21, 16 November 2025.
Abstract High‐energy emissions from thunderclouds have been observed in the Hokuriku Japanese region during winter. The winter thunderclouds have lower altitudes that allow ground measurements due to the shorter distance between electrified regions and observation site, reducing the electrons' free passage distance.

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, Volume 90, Issue 11, November 10, 2025.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...
