Have you ever dreamed about flying off into space? A new study looks at the possible long-term effects of space travel.
When astronauts blast off into space, they are exposed to a type of transfer radiation. Researchers from Georgetown University Medical Center have re-created conditions like that in lab mice.
Immediately, they noticed premature graying and aging in the mice. But a bigger concern is they found free radicals in the gastrointestinal tract, which may encourage cancer.
NASA is sponsoring this research to learn more about the long term risks of space travel.
