Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, Volume 111, Issue 9, Page 4073-4088, 1 September 2026.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Regional and Seasonal Variability in Decreasing Contrail Cirrus Cloudiness Using Sustainable Aviation Fuel

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract The impact of aviation induced contrail cirrus on Earth's radiation budget depends on the optical depth (OD) and the life time of these clouds. Their tendency to enhance global warming may be mitigated by replacing conventional kerosene with fuels that form fewer soot particles, such as sustainable aviation fuels (SAF). The resulting reduction
