These findings were recently clarified by NASA, which indicated that 93 percent of Scott Kelly's genes returned to normal after he returned to Earth while the remaining 7 percent points were missing. According to a NASA’s research — which is still preliminary, with the agency expecting to publish a more complete study this year — it was not Kelly’s genes that changed but how they were expressed. What changed was the way his DNA was transcribed and translated into functional products; the study of such shifts is called epigenetics. The longer Scott Kelly stayed aloft, the greater the number of genes becoming active. Eventi astronomici .
