NASA study confirms initial findings - Space can alter genes

Study NASA Astronaut Scott Kelly's DNA Changed in Space

So when Scott Kelly was selected, along with Mikhail Korniyenko, for a special 340-day so-called year-long mission to the International Space Station, HRP was provided with the opportunity to study the medical, psychological and biomedical challenges faced by astronauts during long-duration spaceflight. Per Live Science, even though Scott and Mark Kelly once boasted the same DNA makeup, Scott's almost yearlong trip on the International Space Station in 2015 and early 2016 changed all of that-leaving him with a lower body mass, altered gut bacteria, and a seeming growth spurt of 2 inches, among other shifts.

The changes are "thought to be from the stresses of space travel, which can cause changes in a cell's biological pathways", read the NASA statement.

Scott has since shrunk back down to his pre-space height and 93 per cent of his genes returned to normal after he landed.

Scott's telomeres, the ends of chromosomes that shorten as you age, became significantly longer in space, but the majority of them shortened within two days of his return to Earth.

Reason She Wasn't at RAW Revealed
This week's episode of Monday Night Raw in Detroit, Michigan, was considered a letdown for many fans in attendance. Whoops! While we can't blast WWE too hard for this, it an unfortunate retraction to make.

But Scott Kelly, the US Space Agency astronaut who broke any record of staying at the International Space Station, changed a little. After Scott returned to Earth from his year-long mission, it took his body time to re-adapt to Earth's gravity. So they made a decision to run some tests and compare Scott's DNA to his brother's after spending some time in space, and they were pretty surprised by the results.

The "Twins Study" was a preliminary step in the lead-up to an eventual long-haul manned mission to Mars. Ten research teams presented their preliminary findings a year ago at NASA's Human Research Program 2017 Investigators' Workshop (IWS). A few, however, still affected Scott six months after his return. Further testing confirmed this change, and revealed that most of the telomeres had shortened again within just two days of his return. Later in 2018, an integrated summary publication of the Twin Study is expected to be released. According to researchers, around 7% of Scott Kelly's genes have shown long-lasting changes when compared to his brother's.

However, seven per cent of the changes to Scott's genetic code remain, including some related to his immune system, DNA fix and bone formation networks that could potentially be permanent. So researchers tested both brothers before, during and after Scott's year in space to map specific changes in the astronauts' physical and mental health.
