Jamie Foster is conducting the study as a researcher at the University of Hawaii with the help of Dr. Margaret McFall-Ngai, a member of the National Academy of Sciences. The Honolulu Star-Advertiser newspapers reported that she studies how spaceflight affects the squids. The research, started in 1989, can help scientists learn about human health during long trips in space.
Squids have a relationship with natural bacteria that help them control their giving off light. Margaret said, “When astronauts are in low gravity, their bodies" relationship with bacteria changes. Bacteria are very important to the human body and health. The relationship of humans with bacteria is disturbed in low gravity, and Jamie has shown that it is true in squids," said Margaret. "And, because it"s a simple system, she can get to the bottom of what happens."
“As astronauts spend more and more time in space, their immune systems don"t function well,” Jamie said. "Their immune systems don"t recognize bacteria easily. They sometimes get sick. Understanding what happens to the squids in space could help solve health problems that astronauts face."
