As health officials around the world tack COVID-19 infection rates, two universities in the U.S. have partnered with Facebook to try to predict infections with real-time survey data.Dr. Alex Reinhart, an assistant teaching professor of statistics and data science at Carnegie Mellon University and a member of the Delphi Group, says that as health officials were struggling with testing capacity in the spring, they realized they might be able to predict infections by analyzing social media."They realized that if we could know when people are experiencing symptoms, they probably experience symptoms a few days before seeing a doctor. That's probably a few days before they get test results back and so that could potentially be an early indicator," Reinhart said.The Delphi Group reached out to Facebook, which agreed to help them survey its users."Every day Facebook takes a random sample of their active users that day in the United States and internationally and invites them through a little blurb at the top of their newsfeed that says, 'you can help coronavirus research' if you take this survey, which is voluntary," Reinhart said.Once Facebook users click on the survey button, it takes them to Carnegie Mellon's page for the survey. The University of Maryland also jumped on board with the project and conducted the survey for all international Facebook users.Facebook does not receive any survey data and only refers to the interested participants to the survey links. So far, more than 30 million people have taken the survey.Dr. Frauke Kreuter, who is working with the University of Maryland in Germany on the international side, says she's not aware of another global survey on COVID-19."There are two factors globally, I would say. One, is that many countries do not have good reporting systems and so they rely even more on alternative data sources. And the other one is, you want to compare yourself to other countries, but for that you need to have kind of the same measure in each country," Kreuter said. "And that's what we're lacking with a lot of measures right now because each country does there reporting slightly different."So far, Carnegie Mellon and the University of Maryland have been able to develop heat maps showing coronavirus symptoms across the country and world. Reinhart says they've been on par with COVID-19 infection rates being reported from health officials and says the survey has helped them identify patterns when it comes to mask-wearing and infection rates."In early September, we started asking questions about mask usage and we soon found that there is a striking difference in mask usage across the country," Reinhart said. "At the time, places that had lower mask usage seemed to be having a worse time in the pandemic."Reinhart says the survey results are helping them learn more about the effects of mask mandates. Researchers are hoping to continue the survey as the pandemic evolves — for example, they hope to begin gauging users on vaccine usage and skepticism in the coming months.The data is available for anyone to view and use."It's different from what you can get from cell phone mobility data that we see people use because we get to directly ask people what they're thinking, how they're feeling, what they're experiencing," Rinehart said. "We'd like as many people as possible to discover this data and use it for their own important research questions." 3430

An astrological mystery event that lit up the daytime sky Wednesday over parts of the upper and midwest and southern Canada may have been solved.Scientists say the fireball was likely a rock that had escaped an asteroid belt between Mars and Jupiter a million or more years ago. They think the chunk of rock has been swirling near earth for awhile.“It’s probably been crossing the Earth’s path countless times, until its time was up in 2020,” Robert Lunsford, fireball report coordinator for the American Meteor Society, told Syracuse.com. “The chance of a collision is infinitesimal, but if you do it several million times, it finally happens.”Apparently the time to finally happen was around noon on Wednesday, December 2. Thousands of people reported seeing a bright streak of light lasting a few seconds, and thousands more heard the deafening boom.Reports came in from several states, including Ohio, Michigan, New York, Pennsylvania,Virginia, as well as parts of Toronto, Ontario and southeast Canada, according to the American Meteor Society.It’s not unusual for meteors to enter Earth’s atmosphere or make it to the ground, however this one was rare because it happened in a very populated area.NASA’s analysis of the event shows the meteoroid entered Earth’s atmosphere over upper New York, roughly between Rochester and Syracuse traveling roughly 56,000 mph. Which is slow by meteor standards.It then broke into pieces roughly 22 miles in the air, which produced the bright flash of light and loud sonic boom.NASA estimates the meteor was roughly three feet across and weighed about 1,800 pounds when it entered the atmosphere.NASA reportedly has three meteor-tracking cameras in Ohio and western Pennsylvania that could have precisely tracked this event, but they were off at the time because of the time of day.“Meteor cameras don’t turn on until night because they’re too sensitive to the sun,” explained Bill Cooke, who tracks meteors for NASA. 1966

As America comes to grips with the nation’s handling of race relations, the Cleveland Indians and Washington Redskins have both said that now is the time to reevaluate their respective team monikers.But the Chicago Blackhawks said they will not follow suit.The National Congress of American Indians have long criticized the name. Activists say these team nicknames play up harmful racial stereotypes."The professional sports industry, specifically the National Football League (NFL), Major League Baseball (MLB), and the National Hockey League (NHL) and the leagues’ team owners have failed to address the racist origins of deplorable race based marketing strategies of the past," the report read. "Often citing a long held myth by non-Native people that 'Indian' mascots 'honor Native people,' American sports businesses such as the NFL’s Washington 'Redsk*ns' and Kansas City 'Chiefs,' MLB’s Cleveland 'Indians' and Atlanta 'Braves,' and the NHL’s Chicago Black Hawks, continue to profit from harmful stereotypes originated during a time when white superiority and segregation were common place."Each of these professional sports businesses attempt to establish a story of honoring Native peoples through the names or mascots; however, each one—be it through logos or traditions (e.g., fight songs, mascots, human impersonators, and fan culture)—diminishes the place, status, and humanity of contemporary Native citizens. What is true about many of the brand origin stories is that team owners during the birth of these brands hoped to gain financially from mocking Native identity. As a result, these businesses perpetuated racial and political inequity. Those who have kept their logos and brands, continue to do so."The Blackhawks say their team name is different as it honors a specific Native American. Black Hawk was a leader of the Sauk Native American Tribe in the early 19th century. Black Hawk served as an ally to the British during the War of 1812 in hopes of pushing the US from Sauk land."The Chicago Blackhawks' name and logo symbolizes an important and historic person, Black Hawk of Illinois' Sac & Fox Nation, whose leadership and life has inspired generations of Native Americans, veterans and the public," the team said in a statement."We celebrate Black Hawk's legacy by offering ongoing reverent examples of Native American culture, traditions and contributions, providing a platform for genuine dialogue with local and national Native American groups. As the team's popularity grew over the past decade, so did that platform and our work with these important organizations."The team said it would “raise awareness” of Black Hawk and Native American people. 2693

An irate homeowner in Louisiana who armed himself with a handgun and chased down a group of teenagers after they rolled his house is behind bars for aggravated assault.The armed confrontation came in response to what Mandeville Police Chief Gerald Sticker said was the group of teens “yearly ritual of ‘rolling or toilet papering’ of homes of fellow students” in the early morning hours of October 27.Craig Scott apparently didn’t think it was funny.Scott armed himself with a semiautomatic handgun and chased down the group of teens, according to Sticker.After he caught up to the group in another section of the neighborhood, Scott pulled his vehicle across the road to block their exit, got out, and confronted the teens with his handgun.Scott was arrested on November 2 and charged with aggravated assault with a firearm and obstruction of a roadway.“Though he had ample opportunity, Mr. Scott never once called 911 or requested police assistance,” Sticker said. “The end clearly did not justify the means this situation.”The teens still may face charges, since “rolling” a house is technically considered criminal mischief, according to Sticker. 1163
