New space station study reveals a hidden side effect of long-term microgravity on the human brain

A study conducted aboard the China Space Station revealed that astronauts exhibited increased movement durations and altered motion profiles when reaching for a target with their arm, compared to a control group and their own baseline motion profiles on Earth (i.e., before flight). Analysis showed that the differences stemmed from reduced initial force and later compensation, indicating that the astronauts tended to underestimate the effective m…
