Space travel warps human brains

The brains of astronauts compress and expand in space, a study by a research team from the University of Michigan found. Using astronaut MRIs taken before and after previous NASA space missions, the researchers were able to show that the brains underwent stress.

Why this matters: The findings could have implications for future space travel, and for treating other health conditions that affect brain function.
