Facebook. This gave researchers a chance to study the health effects of long-term spaceflights. In a study led by Susan Bailey of Colorado State University, researchers tracked the length of each twins’ telomeres before, during, and after Scott’s yearlong spaceflight. Inside of each of our guts lives a vast community of microorganisms, known as the microbiome, which plays an important role in our overall health. This group of cytokines remained elevated for six months. This is important because, as has been documented with other space-bound astronauts, fluids tend to migrate to the head, causing visual impairment and intracranial pressure.

The researchers found that Scott’s telomeres significantly increased in length while he was in space, which was not the case with his Earth-bound brother Mark, whose telomeres remained relatively stable. These cookies do not store any personal information. Much like Bailey’s findings on telomere lengthening, Smith believes the drop in body mass and increase in folate could simply be a result of eating healthier and exercising more often. Both during and immediately after the mission, the researchers found that Scott’s inflammation biomarkers were elevated and that the wall of his carotid artery was thicker than it was preflight. Using the preflight test results as a baseline, Basner found that Scott’s yearlong mission aboard the ISS did not significantly impair his cognitive abilities while inflight. No matter who you are and where you are from, at some point in your life you must have wondered why the mirror flips... © Gizmocrazed - Your Future Tech News Source. The researchers found that while Scott was in space, he excreted some proteins at different concentrations than his Earth-bound brother Mark. D-brief By Jake Parks February 19, 2018 11:18 PM. Previous research has shown that longer telomeres are associated with fewer age-related problems. Lynk & Co reveals the 02 crossover SUV and details European...

In particular, Scott had elevated levels of a protein called aquaporin 2, which helps form the pathways used to carry water through cell membranes in the kidneys. At this point, the researchers do not know whether the thickening of Scott’s carotid artery is a temporary and reversible adaptation to living in space, or if it is evidence of permanent and premature arterial aging. As part of NASA’s Twins Study, researchers collected biological samples from each of the Kellys before sending Scott to the International Space Station for a year starting in March 2016. Similar to the previous project, Andy Feinberg of Johns Hopkins University conducted a study that tracked how each of the twins’ epigenetics (the way that genes express themselves) differed based on their environment. And last month, after nearly two years of study, the ten separate research teams confirmed their preliminary findings (which were initially released in 2017), as well as presented details on their postflight follow-up results.

However, the researchers point out that Scott’s microbiome was different in space than it was preflight, displaying a decreased presence of one branch of bacteria known as Bacteroidetes.

As NASA said in a press release, “observations guide development of future hypotheses,” and NASA’s Twins Study has taken the first step to observing how our genomic blueprint is affected by long-term exposure to microgravity and an increased radiation environment.
