An armed citizen gunned down a shooter at an Oklahoma City restaurant on Thursday, killing him, police said.A man walked into Louie's Grill & Bar and opened fire, striking two people. As the gunman was fleeing the scene, a bystander armed with a pistol confronted the shooter and fatally shot him outside the restaurant, Oklahoma City Police Captain Bo Mathews told reporters."Right now, all I know is that it was just a good Samaritan that was there and looks like he took the right measures to be able to put an end to a terrible, terrible incident," Mathews said.The shooter's motive is not known and his identity has not been confirmed. 652

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

As a number of students across the country head back to school remotely, many children are getting online for their classes every day. But school districts across the country are approaching the use of computer cameras differently."One of the things we're so worried about our kids missing out on is oxytocin. I know we don't think about it that way but that's the chemical we get when we get to be with or see or hear people that are important to us. The feeling of connectivity, that feeling of being okay is really benefited by seeing faces," said Dr. Deborah Gilboa, a family physician and youth development expert also known as "Doctor G" who has created an e-course for parents and educators to help them navigate back to school virtually. Dr. G says if schools have the secure, virtual platforms for live classroom learning, students should turn their cameras on so teachers and other students can see them.As for whether having your camera on or off during class can be appropriate depending on a child's age, Dr G says "parents are experts of their own kids and there may be individual instances where it would be valuable for a child in certain situations to leave their camera off."Dr. G says parents and teachers have a lot more to fear from kids disengaging than engaging uncomfortably. "Middle school is an uncomfortable experience for almost everyone. And I don't mean to diminish that at all but uncomfortable is not the same as unsafe. Helping our kids navigate more uncomfortable situations is often more valuable than protecting them from uncomfortable situations," said Dr. G.At Sanger Unified School District in California, administrators recommend their 12,000 students leave their cameras on when in their virtual classrooms but it's not required."The students do have somewhat of a choice to do that and we know some of our low socio-economic status students, sometimes they're just a little concerned with the background or there’s a lot going on they don't want to show. Or it could be, I don't want someone looking into my bedroom," said Tim Lopez, the Associate Superintendent of Educational Services at Sanger Unified. Lopez says the district is moving to a new virtual learning platform that will allow students to create a virtual background. He believes that and the optional cameras helps level the playing field among students while they're learning from home."There's other things like bandwidth. I've noticed even in my own meetings with adults, they're going on and off and it's like, 'Hey, turn your camera off so we can just listen to what you have to say,'" said Lopez. Whether students' cameras are on or off, both Sanger Unified and Dr. G say teachers will be prepared to ensure students are paying attention in class."I think that our teachers have learned a ton in the last six months about virtual classroom management, just like they spent a lot of time at school learning about in-person classroom management. Mostly, parents don't need to jump in to this conversation unless the teacher asks us to," said Dr. G.Navigating a new digital classroom with brand new online expectations. 3137
