Living in outer space for nearly a year had some interesting effects on American astronaut Scott Kelly. Scientists found signs of increased activity in his immune system, the body’s natural defenses against disease. Life in space also changed the activity of some of Kelly’s genes compared to those of his identical twin brother, who stayed on Earth. The scientists reported their findings at a conference earlier this month. But they admit they do not yet know if the changes are good or bad. The findings are part of a larger, special study of twins from NASA, the United States government’s space agency. The study raises new questions for doctors as agency officials make plans to send people to the planet Mars. Tests of Kelly and his genetically identical brother have given scientists a chance like never before to study details of human biology. They are able to examine how an astronaut’s genes turn on and off in space differently than on Earth.
