Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

, 2014 This article describes the life and work of French astrophysicist Evry Schatzman (1920-2010). He was a pioneer in the study of white dwarfs during the 1940s and was one of the proponents of the wave heating theory of the solar corona.

Thermal Segregation and Reddening in Europa's Double Ridges
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.Abstract The launch of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission in 2023 marked a new era in air quality monitoring by providing high‐frequency, geostationary observations of column NO2 across most of North America. In this study, we present the first implementation of a TEMPO NO2 data assimilation system using the Joint ...

Spectral Properties of Cool Stars: Extended Abundance Analysis of 1617 Planet Search Stars
, 2016 We present a catalog of uniformly determined stellar properties and abundances for 1626 F, G, and K stars using an automated spectral synthesis modeling procedure. All stars were observed using the HIRES spectrograph at Keck Observatory.

Space Weather, Volume 24, Issue 5, May 2026.Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...
