Characterization of High‐Frequency GNSS Total Electron Content Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Global Navigation Satellite System (GNSS)–derived Total Electron Content (TEC) is widely used to investigate ionospheric variability, but has primarily been applied to low‐frequency fluctuations. Here we present a long‐term statistical characterization of high‐frequency (30–500 mHz) TEC variations using multi‐constellation GNSS data from 11 ...

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

Police department design, political pressure, and racial inequality in arrests

American Journal of Political Science, Volume 70, Issue 4, Page 1269-1284, October 2026.
Abstract This paper theorizes a source of bias in discretionary arrests: strategic limits on police officer learning. Officers have a variety of tactics at their disposal besides arrest that they use for less serious offenses when they judge the underlying behavior to be less severe. In departments led by a chief with special expertise in crime control,

Biofloc‐based aquaculture: From monoculture to integrated systems

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract The demand for high‐quality protein has been growing in recent years, led by population growth. The development of aquaculture has been considered one of the solutions to ensure food security worldwide. New farming technologies have been promoted to increase productivity and, at the same time, minimize environmental impacts.
