It has been announced that the answers to how long-term spaceflight affects human health can be obtained from studies of squid sent to the International Space Station (ISS).
Juvenile short-tailed squid bred in the University of Hawaii’s marine laboratory and sent to the ISS have been reported to be instrumental in experiments on how human health is affected during long space missions.
Jamie Foster, a researcher at the US Aeronautics and Space Administration (NASA), said squid have a symbiotic relationship with natural bacteria that help regulate light emission.
“As astronauts spend too much time in space, their immune systems fail. Understanding how squid changes in space could also help solve astronaut health issues,” Foster said. used the expression.

University of Hawaii Professor Margaret McFall-Ngai also pointed out that when astronauts are in low gravity, their body’s relationship to microbes changes.
McFall-Ngai says, “We have found that the symbiosis of humans with their microbes is disrupted at low gravity, and Jamie Foster has found that it works well in squid. It’s a simple system that gets to the bottom of what is causing this problem. .” mentionned.
The juvenile short-tailed squid, sent to the ISS on a SpaceX refueling flight earlier this month, will be returned to Earth for examination in July.
