Spending 340 days aboard the International Space Station between 2015 and 2016 caused changes in astronaut Scott Kelly's body, from his weight down to his genes, according to the results of the NASA Twins Study, released Thursday.The majority of changes that occurred in Kelly's body, compared with his identical brother, Mark, on Earth, returned to normal once he came back from the space station. The study results suggest that human health can be "mostly sustained" for a year in space, the researchers said.On a call with reporters Thursday, Mark thanked Scott for his service to the country and commitment to science by spending a year in space without knowing how it would affect him."I got all the glory, and you got all the work," Scott said, chiding his twin."And I got people coming to my house for tubes of blood," Mark replied in reference to the scientific samples taken during Scott's mission; Scott was collecting the same samples from himself to send back to researchers on Earth.The results show "the resilience and robustness of the human body," said Steven Platts, deputy chief scientist for NASA's Human Research Program, which coordinated the study.Coincidentally, the results are being released just in time for the 58th anniversary of the first manned spaceflight by Soviet cosmonaut Yuri Gagarin.But the much-anticipated study reveals areas that may require countermeasures or safeguards when preparing for longer space missions or missions to deep space, like Mars.The molecular, physiological and behavioral changes were divided into low-, mid-level and high-risk groups. Scott's change in body mass and microbiome were considered low-risk. Shifts in collagen regulation and blood vessel fluid management were mid-level, and genomic instability was regarded as potentially high-risk."When we go into space and experience microgravity and travel at speeds like 17,500 miles an hour, our bodies adapt and continue to function and, by and large, function extremely well," Platts said.The study, which includes the work of 84 scientists who made up 10 teams from 12 universities in eight states, all studying different aspects of the human body in space, was published Thursday in the journal 2227

Presumptive Democratic presidential nominee Joe Biden made one of his first public appearances during the spread of the coronavirus on Sunday, visiting the site Saturday’s tense Black Lives Matter protest in Wilmington, Delaware. Biden visited businesses that were boarded up in Wilmington, and met a few locals during his visit. “We are a nation in pain right now, but we must not allow this pain to destroy us,” Biden’s campaign account tweeted. “As President, I will help lead this conversation — and more importantly, I will listen, just as I did today visiting the site of last night's protests in Wilmington.” 627

Special counsel Robert Mueller did not find Donald Trump's campaign or associates conspired with Russia, Attorney General William Barr said Sunday.Mueller's investigation of whether the President committed obstruction of justice did not conclude the President committed a crime, but it also "does not exonerate him," Barr quoted from Mueller's report.After nearly two years of being under the cloud of the Russia investigation, Trump's presidency is no longer directly under threat from the special counsel probe as the White House turns toward the 2020 campaign, although he still faces the specter of more legal and congressional action from the other investigations that remain ongoing.Trump and his allies charged that Mueller's report fully vindicated the President, while Democrats were already raising questions about Barr making the decision on obstruction, a signal that the fight and the fallout from Mueller's investigation is far from over.Mueller did not make the decision himself on whether to prosecute the President on obstruction. Barr and Deputy Attorney General Rod Rosenstein made the determination the evidence was "not sufficient" to support prosecution.The President went beyond the conclusions of Barr's letter, saying Sunday the findings were a "complete and total exoneration.""No Collusion, No Obstruction, Complete and Total EXONERATION. KEEP AMERICA GREAT!" 1399
