According to NASA, Johns Hopkins researcher Andy Feinberg, one of 10 investigators on the Twins Study, observed variability in patterns of methylation - the process by which genes are chemically turned on and off. Chris Mason of Weill Cornell Medicine reported epigenetic changes in five biological pathways, including those related to oxygen deprivation, DNA fix and bone formation.
Still twins? Astronauts Mark, left, and Scott Kelly.
"We do not yet clearly understand how the space environment fully affects the human body", Pitt said on CBSN, "and of those changes, how do we mitigate them and can we see a correction if we come back to a normal Earth environment?"
Some of the most exciting things that we've seen from looking at gene expression in space is that we really see an explosion, like fireworks taking off, as soon as the human body gets into space. "This likely is within the range for humans under stress, such as mountain climbing or scuba diving". Reports included data on what happened to Scott Kelly, physiologically and psychologically, while he was in space, and compared the data to Mark Kelly, as a control subject on Earth.
What changed in Scott was the way his DNA was transcribed and translated into functional products; the study of such shifts is called epigenetics.
"The two are still very much identical twins", Holm said.
The media told a different story this week, however, as various news sources proclaimed that a fourteenth of Kelly's genetic code had mutated during his time off-planet.
MCCAMMON: That's Christopher Mason from Weill Cornell Medicine. Kelly's transformation suggests longer-term alterations related to at least five biological pathways and functions. "NASA and the other researchers collaborating on these studies expect to announce more comprehensive results on the twins studies this summer". Seven percent of Kelly's gene expression experienced change that did not return to preflight expression after six months back on Earth, based on results published January 31.
MASON: We saw some genes that were activated while he was in space. However, a more pronounced decrease in speed and accuracy was reported postflight, possibly due to re-exposure and adjustment to Earth's gravity, and the busy schedule that enveloped Scott after his mission.
Some outlets, including Ars Technica, The Verge and National Geographic, spotted and combated the misinformation that had been spreading. His twin brother, a retired astronaut, Mark Kelly back on earth.

Skyrim VR will be something that's instantly familiar to those who are already well acquainted with the standard version. When the Elder Scrolls V: Skyrim launched on the Nintendo Switch previous year you probably thought that was it.
One week after contending for his first PGA Tour win in years, Tiger Woods is back in the mix at the Arnold Palmer Invitational . In fact, it's probably best to just skip the whole dang day and don't even put up with the pretense of looking productive.
He also took the opportunity to repeat his oft-used comparison of Iran's Supreme Leader Ayatollah Ali Khamenei to Adolf Hitler. He downplayed Iran's power during the interview, saying that Iran was far from being a rival to Saudi Arabia.
That's why Wall Street will take a wait-and-see approach to find out how much influence the incoming Kudlow really has on policy. He also believes that the ultimate guide to increasing tax revenue is economic growth through reducing tax rates and expansion.
We can not sit back and let events overtake us. "A Britain proud of its past and confident of its future". He stressed the need for the UK's soft power to be able to resort to "hard power to back it up".
I think either one of us that starts brings the same and either one of us that comes on brings the same. That would be special for us in all sorts of ways, because of the Championship and what is at stake".
