 differences in the metabolites and proteins released by cells in space and on Earth along with partial improvement in both gravity conditions. The findings suggest the treatment is safe and could help ensure the health of crew members on future missions and patients on Earth.

Astronauts have high rates of musculoskeletal injuries, and post-traumatic osteoarthritis from ****** injuries is a major contributor to disability across all ages on the ground.

 examined capillary flow, interface reactions, and bubble formation during solidification of brazing alloys in microgravity. Brazing, which bonds similar and dissimilar materials at temperatures above 450°C, is a potential tool for construction, manufacture, and repair of space vehicles and habitats.

 that spaceflight may affect sensory perception and regulation, a finding similar to previous studies. Researchers recommend developing measurement tools with greater sensitivity and questions that capture previous spaceflight experience and astronaut status (commercial or professional) to assess pain experiences.

Astronauts frequently report pain during missions and after returning to Earth, particularly in the back and neck.

 assessed how short-term exposure to microgravity affects pain sensation, biomechanics, bone physiology, and the musculoskeletal system. Results suggested that spaceflight may affect various aspects of sensory perception and regulation, and further investigation is needed to support development of countermeasures and treatments.
