A top trending video on YouTube Wednesday suggested an outspoken survivor of the mass shooting at Marjory Stoneman Douglas High School is an actor.Calls by student David Hogg for stricter gun laws in the days after last week's massacre have made him the subject of smear campaigns and demonstrably false conspiracy theories."I'm not a crisis actor," Hogg told CNN's Anderson Cooper on "AC360" Tuesday. "I'm someone who had to witness this and live through this and I continue to be having to do that."  515

A member of the White House coronavirus task force encouraged people in Michigan on Sunday to "rise up" against closures enacted by the state's governor in the hopes of preventing the spread of COVID-19.On Sunday evening, hours after Michigan Gov. Gretchen Whitmer announced COVID-19 policies that included the suspension of in-person learning at some schools, in-person dining at restaurants and the temporary closure of movie theaters, Dr. Scott Atlas encouraged people to resist the new measures."The only way this stops is if people rise up. You get what you accept," Atlas tweeted. 594

A suspected suicide bombing at a wedding hall in the Afghan capital, Kabul, has killed 40 people and injured dozens more, officials say.The blast ripped through a venue near the city's international airport, where a gathering of religious scholars was taking place, the Afghan interior ministry said. The blast occurred around 6:15 p.m. local time, police said.It was likely caused by a suicide attack, according to Najib Danish, spokesman for the Afghan Ministry of the Interior. The gathering was being held to mark the birthday of the Prophet Mohammed, he said.At least 60 people were injured, the health ministry reported.The security situation in Kabul has deteriorated sharply in the past year.In August, at least 34 people were killed in an attack which targeted an education center. Among the victims were thought to be dozens of teenagers studying English.Then in September, 20 people, including two journalists, were killed in twin bomb attacks on a wrestling club for which ISIS claimed responsibility. The second blast was detonated after emergency services, journalists and police arrived at the scene.In July, the UN released a report stating the number of Afghan civilians killed in the first six months of 2018 had reached a record high. Almost 1,700 civilians were killed from January 1 to June 30, a total higher than at any comparable time over the last 10 years, according to the UN. 1411

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 new campaign is bringing attention to an issue that hasn't been front and center since the pandemic started – missing children.“There has been a lot of awareness, a lot of things have changed, but regarding her case, unfortunately there's nothing,” said Jessica Nu?ez about her missing 15-year-old daughter, Alicia Navarro.Navarro, who has autism, was 14 when she vanished in the middle of the night last September from her home in Glendale, Arizona.Alicia played online games and her mother thinks she was lured away by someone she met online. They had even discussed the dangers in therapy.“And then she wrote me a letter where she sweared to me she was coming back, so that’s what has me very worried, because I know her intention was for her to come back and that’s why I won’t stop looking,” said Nu?ez. “I won’t stop looking until I get answers because it’s been so long.”In a new effort to bring attention to missing children like Alicia Navarro, their pictures will be featured on some gas station pump video screens. Alicia's picture will be up in Arizona.The National Center for Missing & Exploited Children is coordinating the effort featuring various different missing children's pictures in the states they disappeared from.Her mother wants people to know she looks young for her age and has a noticeable scar on her right knuckles.“People tend to forget so my goal is to continue sharing her story and having her image out there,” said Nu?ez.There's also a Facebook page, called "Finding Alicia," where you can share her picture. 1557
