Astronauts’ Brains Shift in Microgravity, Causing Dizziness and Vision Risks

Recent research shows astronauts' brains shift upward and backward in microgravity, causing fluid buildup, dizziness, and potential vision issues, with changes intensifying over longer missions. Some alterations persist post-flight, prompting countermeasures like artificial gravity for safer deep-sp
