Scalable Synthesis of Organic Micro/Nanocrystals via Confined Self‐Assembly in Spinning Fibers

Aggregate, Volume 7, Issue 10, October 2026.
A cost‐effective spinning chemistry strategy is proposed for fabricating organic low‐dimensional micro/nanocrystals (OLCs) via their self‐assembly in the spinning fiber at a speed of 500 m h−1. Notably, the obtained fibers combine optoelectronic properties of OLCs with flexibility of thermoplastic polyurethane, demonstrating tunable emission from 475 ...

MSCM: A geomagnetic model derived from Swarm, CSES, and MSS-1 satellite data and the evolution of the South Atlantic Anomaly

Earth and Planetary Physics
Measurements from geomagnetic satellites continue to underpin advances in geomagnetic field models that describe Earth’s internally generated magnetic field. Here, we present a new field model, MSCM, that integrates vector and scalar data from the Swarm,

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.

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...

Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

Conservation Science and Practice, Volume 8, Issue 10, October 2026.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

Electron Regulation of Proton Cyclotron Waves at Mars

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Proton cyclotron waves (PCWs), generated by the solar wind ionization and subsequent pickup of exospheric hydrogen, offer independent constraints on water loss from Mars. However, translating wave observations into quantitative escape rates has been hindered by an incomplete understanding of wave evolution, particularly the role of electron ...

Substorm Effects on Chorus Emissions Modulated by ULF Waves

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Although cross‐scale wave‐particle interactions play a critical role in energy transfer in the magnetosphere, the influence of geomagnetic activity on the physical mechanisms involved remains unclear. In this study, we investigate this question by analyzing Van Allen Probes‐A observations of an event occurring on 25 July 2016.
