The Journal of Clinical Pharmacology, Volume 66, Issue 8, August 2026.Abstract Spaceflight induces altered physiology that has the potential to alter medication pharmacokinetics due to factors including gastrointestinal motility, fluid balance, circulatory dynamics, hormonal changes, and metabolic alterations. Here, we report the first pharmacokinetic analysis using blood samples during spaceflight.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.Abstract Fjords are globally significant sedimentary archives that record the relationship between glacial, tectonic, and marine processes. Fiordland, on the southwest coast of New Zealand, hosts one of the most extensive temperate fjord provinces in the Southern Hemisphere, yet its postglacial evolution has remained poorly constrained.
