阿拉善盟查肺部有几种方法(铜仁院哪个体检好) (今日更新中)

A month ago, a former student roamed the halls of Marjory Stoneman Douglas High, opening fire on terrified students and teachers at the Florida school.The massacre of 17 students and faculty members added to a grim statistic: three of the 10 deadliest mass shootings in modern US history happened within five months of one another. In the four weeks since the Valentine's Day shooting, the survivors have turned into activists on the national stage. Even as they grieve, they've demanded action on gun reform. In between congressional meetings and protests, they've attended memorials and funerals. 606

A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of "interstellar objects."Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 mph, might have an "artificial origin.""'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018."Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.The paper, written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics, points out that comparable light-sails already exist on earth."Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The light-sail technology might be abundantly used for transportation of cargos between planets or between stars."In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational."This would account for the various anomalies of 'Oumuamua, such as the unusual geometry inferred from its light-curve, its low thermal emission, suggesting high reflectivity, and its deviation from a Keplerian orbit without any sign of a cometary tail or spin-up torques."'Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system.Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. 3063

A Michigan couple faced discrimination due to their sexual orientation, but because of the state's laws, it’s legal. They’re sharing their story because of a new national campaign called Beyond I Do.The campaign highlights states that are legally allowed to discriminate due to sexual orientation, for things like employment, housing and social services, doctors visits or dining at a restaurant.Jami and Krista Contreras are a couple from Oak Park, Michigan. Three years ago, they became new parents and brought their six-day-old newborn to a local pediatrician, but they were denied care. "Your doctor prayed on it and decided she won't see you all today,” Krista Contreras claims one employee at the doctor's office said.The couple was floored. They said they had personally experienced discrimination for their sexual orientation, but they never though it would directly carry over to their newborn in this way.“We spoke to other people and they would say well they can’t do that… that’s not legal and we looked into it and it was legal,” Jami Contreras said.According to the Beyond I Do campaign, 31 states including Michigan don’t have protections for this kind of discrimination. “It was horrifying and humiliating and we just kept thinking god she's 6 days old and she’s already experiencing discrimination,” said Krista.  1358

A new study has found that those who drink moderate amounts of alcohol or coffee lived longer than those who didn’t, reports the Chicago Tribune.The research was led by University of California neurologist Claudia Kawas who tracked 1,700 nonagenarians enrolled in the 90+ study, which began in 2003.According to researchers, those who drank roughly two glasses of beer or wine a day were 18 percent less likely to experience premature death.The findings mean that, according to the research, drinking alcohol increased longevity more than exercise.The study found that participants who exercised 15 to 45 minutes a day cut their risk of early death by 11 percent.And good news for coffee lovers. Participants who drank two cups of coffee a day also increased longevity by 10 percent.The study also found that people who were overweight in their 70s lived longer than normal or underweight people. 904
