How Spaceflight Shifts Astronauts’ Brains Inside Their Skulls
New Insights into the Brain in Zero-G Space exploration continues to reveal surprising effects on the human body. A recent study sheds light on a little-known consequence of spaceflight: the brain shifting inside the skull. In microgravity, the brain’s position changes, influencing neural function and potentially long-term health. This discovery adds to the growing body…

NASA Astronaut Demonstrates How to Weigh Yourself in Space on the ISS
How do you weigh yourself without gravity? On Earth, weighing yourself is a routine act powered by gravity. In space, the absence of a strong gravitational pull means traditional scales don’t work the same way. This week aboard the International Space Station, NASA astronauts shed light on how crew members measure mass and track bodily…

NASA Astronaut Demonstrates How to Weigh Yourself in Space on the ISS Week of Nov. 17–21, 2025
How do you weigh yourself in space? Weighing yourself in space sounds like a paradox. In microgravity, objects don’t pull toward the Earth the same way they do on the surface. Yet the International Space Station (ISS) and its crew still need to understand mass and how it affects everything from exercise routines to docking…
