Feasibility studies on regional aircraft retrofitted with hybrid-electric powertrains
Aerospace Science and TechnologyHybrid -electric powertrains are considered a promising technology for mitigating noxious emissions and promoting aviation decarbonization, particularly in regional segments with limited flight energy requirements. However, assessing their potential quantitatively proves challenging owing to system complexity and enlarged dimensions of the design space.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Iterative black auroral stripes were identified in auroral images obtained by the low‐altitude microsatellite Reimei. These steady and narrow black stripes are a remarkable feature of diffuse auroras generated by energetic electrons precipitating at higher latitudes than pulsating auroras.

The greenhouse gas emissions of psychological conferences and what we can do about it
Applied Psychology: Health and Well-Being, Volume 18, Issue 3, June 2026.Abstract The UN Sustainable Development Goals highlight the relevance of climate change for global health. At the same time, the academic community—including health‐related disciplines such as psychology and behavioural medicine—contributes substantially to greenhouse gas emissions, particularly through work‐related travel. To inform discussions on the
