Updates, Examples and Validation of the Global Ionosphere Thermosphere Model

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study provides an updated description, example simulations, and validation of the Global Ionosphere Thermosphere Model (GITM). The updates to GITM include using an exothermic semi‐implicit chemistry scheme that no longer requires an altitude dependent heating efficiency; an ionospheric wind‐driven dynamo; improved neutral, ion, and ...

Crystals as Rockets: Modulation of the Salient Temperature in Cocrystals by Solvent Mixture Composition

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Compositionally engineered mixed solvated cocrystals enable modulation of thermosalient actuation. Guest ratio controls thermosalient temperature and propulsion intensity, providing a tunable platform for designing crystalline systems that exhibit stimuli‐responsive mechanical motion.

Microspherules formed by lightning strikes

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 743-767, May 2026.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Anti‐Astrotropik — Outer space, technology and resistance in the tropics

Singapore Journal of Tropical Geography, Volume 47, Issue 2, Page 289-316, May 2026.
This paper traces an intellectual and geographical arc of thinking about outer space in the tropics, connecting Peter Redfield's Space in the Tropics: From Convicts to Rockets in French Guiana (2000), Sean T. Mitchell's Constellations of Inequality: Space, Race, and Utopia in Brazil (2017) and Asif Siddiqi's Cosmic Fragments: Dislocation and Discontent
