Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

Biodegradable, Breathable, and Skin‐Friendly Solution‐Blown Quercetin Nanofibers for Antiviral Nonwoven Filter

EcoMat, Volume 8, Issue 4, April 2026.
A nanofiber filter of quercetin and poly(ethylene oxide), produced through a solution‐blowing technique, serves as an eco‐friendly, high‐performance alternative for antiviral mask filters. The resulting material combines effective particle filtration with excellent breathability, robust mechanical strength, and rapid biodegradability, while also ...

Aerospace Engineering Undergraduate Laboratory Courses: A Systematic Review (1990–2025)

Computer Applications in Engineering Education, Volume 34, Issue 2, March 2026.
ABSTRACT This review examines the evolution of undergraduate aerospace engineering (AE) laboratories from 1990 to 2025, focusing on course formats, pedagogy, technology, and assessment. Once centered on traditional demonstration‐based exercises, AE laboratories have increasingly shifted toward hands‐on, project‐based, and hybrid physical‐virtual models
