The spread of COVID-19 is tough to trace and even tougher to predict, but researchers at Pittsburgh’s Carnegie Mellon University created an early warning system to help protect you from the virusMathematics professor Po-Shen Loh developed an app called NOVID, a contact-tracing app, to help communities see the virus coming before they get infected.On top of creating a brand new app, Loh teaches math to middle-school students online from his own office-turned-broadcast studio. He’s also the national coach for the United States Math Olympiad team that competes around the world.But when the pandemic hit, Loh wanted to take on one more project. “I like things that are supposed to be impossible, that can’t be done,” said Loh. Stopping the spread of the coronavirus seemed to fit the bill.“The problem with COVID is it spreads before you know you have it, that’s what makes COVID different," Loh said. "The only way you can control this disease is in helping people to know whether or not COVID is coming close to them in advance."That’s where the NOVID app can help, said Loh. “Shows the virus coming towards you based on your relationship network, so that you can protect yourselves from others before you actually get infected," Loh explained of the app. "This is in contrast to most other contact tracing apps that are designed to protect others from you."The app shows you positive cases in degrees of separation. A positive case in the first degree would be someone you live with. The second degree could be your coworker or a friend. The third degree would be that person’s spouse or child. Each degree of separation is a possible pathway for you to come in contact with COVID-19.“This thing shows you the virus coming towards you, kind of like a hurricane satellite shows you a hurricane coming towards you,” said Loh.In addition to showing you cases as they pop up around you, the app can track the distance between phones down to the inch.It uses both Bluetooth and ultrasound waves to give you that measurement to make sure you’re safely social distancing.“We don’t know of any other contact-tracing app in the entire world which will tell you, ‘here’s how far away we think the device was,’” said Loh.The safety of your personal information is one of the most important features of this app. It collects data, while you stay completely anonymous.“Many people are distrustful of an app that does contact tracing,” said Loh. “We never ask for your phone number or email."Those who are positive can self-report their case in the app. Loh is also working with cities and counties to integrate NOVID into health departments across the country. He said the health departments would issue a ticket with a number to each person who tests positive for the virus.That person would enter the number into their NOVID app, anonymously reporting the positive case in the community.“If this thing actually caught on, you’d see in all the cities and towns, whether it’s rural or urban, whenever COVID starts to rise up, you’d start to see everyone take caution. Not because anyone forced them to, but because they saw this is what would be useful,” said Loh.To create the powerful community resource Loh is hoping for, he said more people need to know about the app.“Right now, we only respond when the intensive care units are full, and then it’s too late, and people die on the sidewalk. But, what we wish would happen, is that people could see it coming, and then, everyone starts to be careful at the right time. With more traction, we can save more lives,” he said.Loh is hoping he can not only help save lives but help bring back life as we knew it.“The goal of what we’re trying to do is to give people headlights to drive in the dark. Our app is not designed to let other people control you; our app is designed to help you control your life,” said Loh.For more information on NOVID or to download it, click HERE. 3928

The Trump campaign has filed a second lawsuit to stop ballot counting the day after the election. This time in Pennsylvania.In a release sent to supporters, the president’s campaign says they are taking several legal actions concerning Pennsylvania ballots. The first is they are “moving to intervene in the existing Supreme Court litigation over the Pennsylvania Supreme Court’s unlawful extension of the mail-in ballot receipt deadline.”Trump’s campaign is also filing suit to stop ballot counting because they claim election officials are counting and processing ballots out of sight of Republican poll observers.“In Philadelphia and elsewhere, Democrat officials forced our observers to stay 25 feet or more from the counting process, leaving no meaningful way whatsoever for our observers to do their jobs,” the statement from Justin Clark, Trump’s deputy campaign manager, reads.With about 84 percent of the ballots counted, Trump leads Biden by almost 300,000 votes. This is similar language used by the Trump campaign when they said they filed in Michigan Wednesday morning. The Trump campaign says it is calling for a temporary halt in the counting in Michigan until it is given “meaningful access” in numerous locations and allowed to review ballots that already have been opened and processed. Trump is running slightly behind Democratic nominee Joe Biden in Michigan. 1387

The US ambassador to Mexico was not invited to a meeting between senior White House adviser Jared Kushner and Mexican officials, including President Enrique Pe?a Nieto, a US official told CNN.Roberta Jacobson, a career diplomat who has more than 30 years of experience in the region, announced her retirement earlier this month effective in May. Her departure comes at a time when US relations with Mexico have been strained over issues related to trade and migration.Kimberly Breier, who was just nominated to be the new assistant secretary for Western Hemisphere -- a senior State Department position Jacobson previously held -- was with Kushner at the Wednesday meeting.The New York Times first reported that Jacobson was not at the meeting.The timing of the meeting came amid NAFTA negotiations and questions over President Donald Trump's tariff proposal. It also comes shortly after Kushner had his security clearance downgraded because he had not obtained his full clearance.  995

The White House on Tuesday said the Justice Department should consider a criminal prosecution of former FBI Director James Comey, claiming he had leaked privileged information to the press and offered false testimony to Congress."It's something they should certainly look at," press secretary Sarah Sanders told reporters when asked whether the administration should prosecute Comey. She acknowledged that it was "not the President's role" to determine which criminal investigations are taken up by the Justice Department.The question arose as Sanders defended Trump's decision to fire Comey earlier this year, a choice Trump's former chief strategist called a mistake this week.Speaking to "60 Minutes" on CBS, Steve Bannon called the Comey decision the worst mistake in "modern political history." 812

The U.S. Supreme Court has declined to weigh in on the battle over pension reform in the city of San Diego. The decision leaves in place a California Supreme Court decision from last year that called pension reform into question and required a lower court to come up with a remedy. It could end up costing the city billions. In 2012, San Diego voters approved Proposition B with 65 percent in-favor. The measure ended pensions for nearly all new city hires, instead switching them to 401(k) type plans. Around the time, the city faced a billion pension liability, comprising 20 percent of the budget. "It is saving us, literally, hundreds of millions of dollars," Mayor Kevin Faulconer said Monday. "That's why it's important, so we can invest dollars back into neighborhoods."The city, however, is now on the legal defensive. Back in 2012, then-mayor Jerry Sanders campaigned on behalf of the measure. Labor unions argued Sanders' involvement required the city to meet and confer with unions before changing their terms of employment. The city argued that Sanders was exercising his First Amendment right to endorse the measure, which got to the ballot via a citizens initiative. The state Public Employee Retirement Board sided with the unions. So did the California Supreme Court, which last year ordered lower courts to decide a remedy. "There is not even a breath of a suggestion in this case that any public officials First Amendment rights have been violated," said Ann Smith, the attorney representing the labor unions. In a statement, Sanders, who now heads the San Diego Regional Chamber of Commerce, called the Supreme Court's decision disappointing but not unexpected. Smith said a lower court decision could make a decision within 30 days. It could impact as many as 4,000 city employees. 1813
