A new study based on astronauts Scott Kelly and Mark Kelly\u2014identical twins\u2014found that space travel can alter DNA, at least the way we’re doing space travel now. The study found that 7% of Scott Kelly’s DNA did not return to normal after a one-year mission in space. Gizmodo<\/em> noted<\/a> that the change is epigenetic in nature, rather than simply genetic. It’s the way Mr. Kelly’s genes are expressed, not the genes themselves, otherwise he would now be a new species. Important semantics aside, the changes were thought to be caused by\u00a0\u00aboxygen-deprivation stress, increased inflammation, and dramatic nutrient shifts that affect gene expression,\u00bb according<\/a> to CNN. It’s important to both understand and solve these kinds of issues when it comes to prolonged space flight, travel to Mars, and other space-related activities, and the Kellys being part of this study will pay untold dividends towards that understanding. The video below on the topic is from NBC.<\/p>\n","protected":false},"author":21,"featured_media":36594,"comment_status":"open","ping_status":"closed","template":"","format":"standard","tags":[],"class_list":["post-36589","cool-stuff-found","type-cool-stuff-found","status-publish","format-standard","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nAstronaut Twin Study Finds Space Travel Can Alter DNA - The Mac Observer<\/title>\n<meta name=\"description\" content=\"A new study based on astronauts Scott Kelly and Mark Kelly\u2014identical twins\u2014found that space travel can alter DNA, at least the way we're doing space travel now.
