"An american twins, both astronauts, gave researchers the opportunity to investigate how man is affected by rymdvistelser."
"Scott Kelly spent 340 days on the space station ISS. His identical twin Mark Kelly stayed on the earth, and tvillingparet fit thus perfectly in order to compare how long rymdvistelser really affect people."
"During the 25 months, the researchers of the twins' blood, urine and stool, both before and after the rymdvistelsen in Scott's case."
"– this twin study is the most comprehensive insight we had when it comes to how the human body is affected by spaceflight, " says Susan Bailey, a biologist at Colorado State University, to Nature."
"Scott Kelly was hit during the rymdvistelsen of a thickening of the halshinnan and the retina, loss of weight, changes in the intestinal flora, decreased cognitive abilities, and that the genome was affected."
"– the Return was much worse than the alignment when I got up there, " says Scott Kelly, according to the Reuters news agency, adding that it felt like he had the flu the first few days after landing, and that he was tired for a long time to come."
"After six months on the earth reverted most of the changes in Scott Kelly's body to normal again. But it was not everything. Some genetic changes, affecting the chromosomes, remained."
"It may depend on, among other things rymdstrålning or weightlessness, according to the researchers."
"Although the current study only deals with two people hope Nasa that it should be helpful for future research."
"identical twins Mark and Scott Kelly are both astronauts at the u.s. space agency Nasa."
"Scott Kelly was a total of 520 days in space, of which 340 related. Mark Kelly has been in space in a total of 54 days, spread out on four occasions."
"Both of them have now stopped at Nasa. Sccott Kelly has written and spoken about their time in space, while Land is betting on a political career and trying to get into the senate."
