Understanding Oral Hygiene and Periodontal Health in Space Using a Bedrest Analog Model for Weightlessness (NASA Sensorimotor Countermeasures Study)

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Aims To investigate longitudinal alterations in oral hygiene, gingival inflammation, and salivary secretion during a 60‐day head‐down tilt bed rest (HDTBR) protocol as a validated ground‐based analog of microgravity. Materials and Methods Twenty‐four healthy volunteers participated in a 60‐day, 6° HDTBR study conducted under strictly ...

Volumetric Absorptive Microsampling During Spaceflight for Analysis of Acetaminophen Pharmacokinetics in Whole Blood

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.

Undergraduate Women Socially Develop Science Identities Through Everyday Talk and Recognition: A Mixed Methods Study

Journal of Research in Science Teaching, Volume 63, Issue 6, Page 531-549, August 2026.
ABSTRACT Science identity is a key predictor of persistence in STEM. Although prior research has established the importance of social recognition for identity development, less is known about how recognition operates within informal, everyday interactions.

Arase/LEPi Observations of Low‐Energy H+ and O+ Ion Fluxes in the Inner Magnetosphere: Implications for the Relationship Between Warm Plasma Cloak and Oxygen Torus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We investigated the spatial distributions and pitch‐angle distributions of 30–300 eV H+ and O+ ion fluxes using data obtained by the low‐energy particle experiments‐ion mass analyzer (LEPi) onboard the Arase satellite. A statistical analysis over 3.7 years reveals that the H+ ion flux is enhanced at L > 4 from the premidnight sector through ...
