Plasticity of the heart in response to changes in physical activity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The heart adapts to changes in physical activity, with inactivity (e.g. bed rest or spaceflight) causing cardiac atrophy and ventricular stiffening, and endurance exercise training leading to eccentric hypertrophy and improved ventricular compliance.

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

The direct application and potential indirect contribution of space law for solar radiation modification governance

open access: yesReview of European, Comparative &International Environmental Law, Volume 34, Issue 1, Page 170-180, November 2025.
Abstract Solar radiation modification (SRM) reflects sunlight back into space and could rapidly cool Earth, potentially reducing the harms of dangerous climate change. Current international law fails to directly and comprehensively address the transboundary, regional and global governance challenges that SRM presents.
