Investigating the Impact of Rocket Exhaust on Ionospheric Disturbances
Space Weather, Volume 24, Issue 5, May 2026.Abstract The study of chemical releases into the ionosphere is crucial for understanding ionospheric dynamics and managing space environmental effects. In this work, we investigate the impact of rocket exhaust emissions, particularly CO2 and H2O, on electron density in the ionosphere.

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 ...

Headache: The Journal of Head and Face Pain, Volume 66, Issue 5, Page 1128-1147, May 2026.Abstract Objective Calcitonin gene‐related peptide (CGRP) inhibitors, including monoclonal antibodies (mAbs) and small‐molecule antagonists (gepants), have transformed migraine treatment. Although clinical trials established their efficacy and initial safety, post‐marketing surveillance is essential for understanding their real‐world safety profile in ...

Numerical Study on Response Characteristics of Solid Rocket Pintle Motor
Journal of Aerospace Technology and Management, 2019 Pintle technology is currently a versatile technology used in a solid rocket motor (SRM) to control the desired thrust by changing the nozzle throat area, while effectively controlling the chamber pressure at the same time.

Ryugu reference project: Recommendations from the measurement definition team
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

The 2024 European Union report on pesticide residues in food
EFSA Journal, Volume 24, Issue 5, May 2026.Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), the European Food Safety Authority publishes an annual report assessing pesticide residue levels in food. In 2024, 9842 samples were analysed as part of the EU‐coordinated multiannual control programme subset, of which 1.2% were found to be non‐compliant.
