The twin study is a revolutionary analysis of the molecular, physiological, and behavioral changes that happens to the human body in space in a year span. This is the first time it's ever been done and we're here to break it down for you.

Keep an eye out for "SICK"!

"This first-of-its-kind investigation has provided clues about how a long duration space flight changes the regulation of molecules in the body and the relationship of these changes with physiological changes in the body due to space flight such as vascular remodeling and vision problems," said senior author Brinda Rana, PhD, professor in the Department of Psychiatry at UC San Diego School of Medicine."

"Emmanuel Mignot of Stanford University studied the Immunological responses of the twins by introducing them to the flu vaccine preflight, inflight (for Scott) and postflight – each at one year intervals. Following each vaccination, both twins had an increased immune cell response to the flu at comparable levels. This is the expected response, protecting the human body from contracting the flu virus."

No, Scott Kelly's Year in Space Didn't Mutate His DNA
"That these levels of expression haven’t boomeranged to pre-spaceflight values is humongously different than saying Kelly’s DNA didn’t “return to normal after a sojourn in space.” “We had no idea what to expect, and this is the first experiment of its kind, so this sets the bar for future studies of astronauts,” Mason says. “Nonetheless, this number is likely within the range for humans under stress, such as climbing a mountain, or SCUBA diving.”
