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 terms "signing bonus: and "recruiting" are usually reserved fro top-paid professional athletes. Now add nurses to that list.Hospitals across the country are facing a shortage of nurses, and they're stepping up the incentives to fill the jobs.Patients aren't the only ones happy that Christina Predo is working at UCHealth. After all, the hospital gave her a ,000 signing bonus as an incentive to take the job."Other offers before that hadn't even come close," Predo said.Predo needed to find a job where her husband was being relocated. With several offers on the table, in the end it was UCHealth's signing bonus and other perks that sealed the deal."They offered all sorts of help to help move here," Predo said. "They offered someone to actually find me a neighborhood to live in which was awesome. None of the other hospitals actually offered to do that."What's behind the big bonuses? A shortage of nurses. With more than 500,000 seasoned registered nurses expected to retire by 2022, there's a projected need for 1.1 million new nurses to avoid a shortage.Hospitals across the country, including UCHealth, are feeling that crunch already."Well I'll tell you what, we have about 300 positions open," said Kathy Howell, Chief Nursing Executive at UCHealth.Howell says growth has created a greater demand for nurses, and a good economy means more nurses are opting to retire. That's why there's a concerted effort to make the offer to work at UCHealth as attractive as possible, even allowing out-of-state nurses to try out the hospital for a year and covering their housing costs."They go from assignment to assignment within our health system," Howell says. "We also give them a housing stipend, and we usually convert between 35 and 40 percent of them to full-time employees."Most new nurse hires get around ,000 to sign, which Howell doesn't think is out of line."When you look at what turnover of nurses costs and what not having the right nursing complement is to your hospital," Howell says. "That is a very reasonable investment."Ultimately, Howell says it's about delivering the right care to patients, and creating the right environment for the nurses they hire."It's a real comradery. Everyone is super super nice, you really have a say in what you're doing here, your opinion actually matters you don't feel like a number," Predo said.A new way to fill the need for nurses, with a payoff, multifold. 2476

The woman who opened fire at YouTube headquarters Tuesday practiced shooting at a gun range hours before the attack, police said. She then took her 9 mm Smith & Wesson handgun to the Silicon Valley campus and shot three people she apparently didn't know, San Bruno police Chief Ed Barberini said.All this because Nasim Najafi Aghdam was upset with YouTube's practices and policies."We know she was upset with YouTube, and now we've determined that was the motive," Barberini said.Aghdam shot and wounded three people before killing herself. Two of her victims have been released from the hospital, and one remains in serious condition.Barberini said the shooter did not have a link or relationship with the three people she shot.  747

The skies over several US states and Ontario, Canada, lit up briefly on Wednesday as a presumed fireball streaked over the daytime sky.Despite the midday sun, the fireball was clearly visible in videos captured at the time of the event.According to the American Meteor Society, dozens of eyewitnesses reported seeing the fireball shortly after 12 p.m. ET. The reports were clustered around Lake Ontario, but the organization received reports from Michigan, Ohio, and even as far away as Maryland and Virginia.An eyewitness in Ohio reported to the American Meteor Society, “It was like a ball of fire with a tail...surreal to see in the daytime.”Another eyewitness in Ontario said, “Astonishing, amazing, still get goosebumps talking about it.”What caused the bright flash hasn’t been confirmed, but is presumed to be a meteor. Meteors are not uncommon events, as small rocks and objects enter the Earth’s atmosphere on a daily basis. Most of the time, the atmosphere causes these objects to burn up before reaching the ground. 1034

The White House on Friday announced a policy to ban most transgender people from serving in the US military.Following a Pentagon policy review after a tweet by President Donald Trump last year, the White House said the policy will say "transgender persons with a history or diagnosis of gender dysphoria -- individuals who the policies state may require substantial medical treatment, including medications and surgery -- are disqualified from military service except under certain limited circumstances." 513
