A plane dragging the Confederate flag was seen circling Bristol Motor Speedway prior to the NASCAR All-Star race Wednesday night.Videos shared to Twitter and other social media sites show the plane dragging the flag, along with the website for the Sons of Confederate Veterans.NASCAR banned the Confederate flag from racetracks in June, following the death of George Floyd and resulting weekslong protests against police brutality and systemic racism. 459

A viral video showing security camera footage taken in Chula Vista, California on Halloween night may help restore your faith in the honor system. Kim Manalo's family joined the throngs of trick-or-treaters racing door-to-door in their neighborhood.  Manalo wanted to keep the spirit of Halloween alive at her home while they were out, so she left a bowl filled with candy outside their door with a note asking people to help themselves.  Her hope was that people would leave a treat for the next candy-seeker."We came home to an empty bowl and hoped there weren't greedy kids that didn't leave some behind for others," Manalo wrote on her post.She studied security footage to see if perhaps someone grabbed more than their share of goodies. What Manalo found on her security camera video was a surprise that almost made her cry."Instead we found this clip of a wonderful soul who shared some candy from his own bag to keep the halloween spirit going for other kids," Manalo she wrote.The video shows one of the boys reach into his bag and place some of his own candy in the bowl for the next trick-or-treaters. “He didn't even know the camera was there,” Manalo said. “None of his friends knew and to take that second out of his time from his own stuff just really warmed my heart.”San Diego-based KGTV posted the surveillance video on Facebook after Manalo's friend shared the footage with reporter Joe Little.  The video has garnered hundreds of reactions, shares, and comments."If only all of us raised our children to be so thoughtful even when no one is seemingly looking. He will change the world someday if he keeps it up," wrote Jeremy Ellis.The identity of the thoughtful boy remains a mystery, but numerous adoring Facebook fans are looking for clues to thank him for inspiring the spirit of community. 1941

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 pedestrian bridge suddenly collapsed onto the road below near Florida International University, crushing cars and killing at least six people Thursday.Hours after the bridge collapsed, officials said early Friday that the rescue mission is now a recovery operation.Emergency crews worked overnight in what Miami-Dade Police spokesman Alvaro Zavaleta called a "very slow process" in order to preserve evidence and the safety of possible victims and rescuers, because of unstable conditions at the bridge.At least nine people were transported to hospitals for treatment, authorities said.Witnesses described hearing a loud boom Thursday and moments later, finding victims, including construction workers across the wreckage and people trapped in cars.Senator Marco Rubio, who visited the site Thursday, posted on Twitter: "The cables that suspend the #Miami bridge had loosened & the engineering firm ordered that they be tightened. They were being tightened when it collapsed today." Rubio has been a visiting professor at the university for the past 10 years.The bridge's main span, which weighs 950 ton, had just been installed Saturday over eight lanes, near the university in Miami.  1205

A study released earlier this year conducted by university researchers from both the UK and US indicated that climate change is causing more extreme rainfall events from hurricanes, specifically among Caribbean islands.The study was authored by researchers from Bristol University in the UK and MIT in the US.The researchers said that the focus on the study was on extreme rainfall from hurricanes, like Hurricane Dorian which, stalled over the Bahamas last year.“Overall, the results suggest that the Eastern Caribbean region in particular (Puerto Rico and the Dominican Republic) is likely to benefit from a reduction in extreme hurricane precipitation events resulting from increased efforts to stabilize global warming,” the study reads, pointing to the Paris Climate Accord as a benchmark for minimizing the impact of extreme rainfall events from hurricanes.The research found that events like Hurricane Maria, which struck Puerto Rico in 2017, would happen twice as frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 Celsius, which is the goal of the Paris Climate Accord.In the case of Hurricane Dorian, an event like that could strike the Bahamas four to five times more frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 degrees. A seemingly small difference could be what saves thousands of lives and billions of dollars in damage.One of the study’s authors told CBS News there is particular concern that the impact of extreme rainfall events could occur over poorer island nations in the Caribbean."The findings are alarming and illustrate the urgent need to tackle global warming to reduce the likelihood of extreme rainfall events and their catastrophic consequences, particularly for poorer countries which take many years to recover," Emily Vosper, a researcher at the University of Bristol, told CBS News.The full study is available here. 1912
