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 Akron, Ohio man will spend at least the next 20 years in prison for selling fentanyl to a woman who overdosed on the drug and died nearly three years ago.Jurmaine A. Jeffries, 29, was convicted of distribution of fentanyl and possession with intent to distribute the drug.A jury found that the fentanyl Jeffries sold the woman resulted in her death.On Sept. 16, 2015, the day of her death, the woman texted and called Jeffries to ask about buying heroin. He responded to her messages and told her "B right there."Cell phone records placed Jeffries in the area near the woman's house on the day she died, authorities said.According to the U.S. Attorney's Office, after the woman died, police used her phone to text Jeffries about buying more drugs. Police arrested him when he showed up at the woman's house with fentanyl on his person.Sentencing will take place at a later date, but Jeffries is facing a mandatory minimum of two decades in prison for his charges.“We will prosecute those who sell fentanyl and other drugs that kill our friends and neighbors,” U.S. Attorney Justin E. Herdman said. “This defendant drove around Akron delivering poison for profit. The Akron Police Department and all our law enforcement partners did a tremendous job bringing this man to justice.” 1315

An email sent to businesses and organizations across the country on Thursday appears to be a hoax, authorities from the New York Police Department said. According to NYPD's Twitter page, the email, which prompts victims to make a Bitcoin payment, is a scheme to either "cause disruption and/or obtain money."Police in New York said they have searched various places where the email has been sent, and no devices have been found. NYPD said they will continue to respond to calls for service if anyone receives a threat. Authorities in other states have conducted similar searches. Police in Tennessee said they believe the email originated from outside of the United States. The FBI issued the following statement: 746

As floodwaters started receding in central Texas, authorities discovered the body of a second victim in this week's deluge.The woman's body was found in Llano County, one of the areas inundated by the swollen Llano River, county officials said Wednesday. The woman's name has not been publicly released.On Tuesday, another body was found in the Colorado River in neighboring Burnet County, sheriff's office Capt. Tom Dillard said. Near-record flood levels swamped homes and caused a bridge to collapse.But there's a sliver of good news: While flood warnings are still in effect due to ongoing rain Wednesday, the Llano River's depth has dropped significantly."Right now, the Llano River is at about 12 ? feet, down from just shy of 40 feet yesterday," Llano County Emergency Management Coordinator Ron Anderson said Wednesday. 834

Apple has defended its tax arrangements after reports revealed it had shifted its mountain of offshore cash from Ireland to a tax haven in the English Channel.A trove of documents known as the Paradise Papers have reportedly shed light on Apple's search for a new place to store the huge sums, after more than two decades of benefiting from artificially low taxes in Ireland. The company has resisted bringing the money back to the U.S. because of the massive tax bill it would face.Coverage of the documents is being coordinated by the International Consortium of Investigative Journalists, which has shared them with major media outlets including The New York Times, The Guardian and the BBC. 702
