An artificial intelligence tool can help doctors when deciding which COVID-19 patients can be sent home, according to a study that started in May.Researchers at New York University used the AI tool to analyze thousands of COVID-19 cases. The team used data from Asia and Europe to develop the model.It uses lab results, vital signs and oxygen requirements to determine how the patient will do over the next few days.The study has found the AI tool can identify patients that will do well with 90% precision, which could help doctors prioritize care and make discharging plans for others.Doctors always make the final call, but the AI tool can help reaffirm their decisions.“It's augmenting, but it's also teaching a little bit, because you know when the physicians see a patient that looks well, but the models say they may not be well, they can look at the, the features right? The vital signs and labs and other things that are saying that this patient isn't well and then they can start to understand or create a mental model,” said Yin Aphinyanaphongs, Director of Translational Clinical Informatics for DataCore, NYU.The researchers are still running randomized trials for about another two months, looking at the average time patients spend in the hospital.The hope is the AI tool could help reduce the length of stay.“That's extremely compelling because now you don't just show oh I have a model that can predict a favorable outcome, but now you have a model, right, that actually affects the outcome,” said Aphinyanaphongs.Another team at NYU is now conducting a survey among doctors that have used the tool. One facility has already implemented it.The researchers wanted to make sure it's easy for other organizations to start -- so the software can be up and running in about half a day. 1805

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 disinfecting wipes and sprays fly off store shelves, companies are looking for new ways to keep surfaces coronavirus-free. Some are looking at repurposing UV light technology, a cleaning solution that’s been used for decades.Ava Robotics and the Massachusetts Institute of Technology partnered on a project to create a robot that uses UV-C light to disinfect large areas.“It was about a 4,000 square foot space. It was able to disinfect that in less than 30 minutes,” said Youssef Saleh with Ava Robotics.The purpose -- cleaning large, busy spaces of virus and bacteria, specifically coronavirus.“UV is not new. Robots are not new themselves,” Saleh said.“It's actually been in practice in hospitals for probably four decades plus,” said Dr. Eric Hill, the Chair of Emergency Services at Medical Center of Aurora. It’s usually used to sterilize rooms.“Anything that the light hits, it can kill. So it has to be in direct contact with the light beam and it has to be in contact for a certain period of time,” Hill said.“There are three factors of effectiveness of UV light, the first is the power itself,” Saleh explained. “Then there's the distance to the object that you're trying to disinfect, and then there is the amount of time.”"We cannot see it, it's the same kind of UV radiation you’d get from the sun,” Hill said. “It works by destroying the DNA and the RNA of the organism. And it doesn't affect just viruses, it affects bacteria, viruses, mold, and spores.”While it can kill germs, it can also do damage to us. UV light plays a role in diseases like skin cancer. “It is dangerous for humans to be in direct contact with it,” Dr. Hill said.That’s why the project with Ava Robotics and MIT also factors in safety for humans.“Safety elements have to be part of the solution, thought through, and understood,” Saleh said. The team is working on making the robot more adaptable to changing spaces, like warehouses, and potentially other large spaces like grocery stores and schoolsBut Hill says UV light isn’t a complete replacement for traditional cleaning methods.“It does not take the place of things like wiping something down,” he said. “But after you do that...adding in a UV light system can really hit in a broad area...and get all the microorganisms that were in there.”Hill also warns consumers that are interested in this to look at products closely.“Several hundred dollars is realistic for a good UV light system,” he explained. “We have seen much more of a demand of it, if you go on Amazon the amount of UV light products I’ve seen pushed out is incredible.” 2591

Amid the COVID-19 pandemic, with millions of schoolchildren still learning remotely as the weather turns colder, some might benefit from a few investments in their at-home experience.The following items, all under , can help make distance learning more appealing to even the youngest learners.1. New background decorationsWhen your child is on screen all day, sprucing up their background with a wall decal or two can help keep them in school mode, especially when virtual backgrounds are prohibited by school systems. Consider shopping for a school-themed wall decal like crayons, pencils, numbers or books. A quick search on Amazon or Etsy pulls up dozens of choices for under .2. A clip-on selfie lightSmall selfie lights that attach to the side of a screen can help light up your child’s face and ensure the teacher can see them, too. This light is especially useful if your student is sitting in a dark room or has a light or window behind them. You’ll want to make sure it’s not too bright for their eyes, but selfie lights generally allow you to adjust the brightness.3. A paper plannerEven though distance learning largely takes place on a computer, it’s nice for kids to get some practice staying organized on paper. To keep track of homework assignments, due dates and even online classes, consider buying a small paper planner for your student. A pack of fine-tip colorful pens can also be a nice bonus.4. Online programs to boost learningAfter checking which free online programs are available through your child’s school, you might want to supplement your child’s learning with some relatively inexpensive academic games. Prodigy, a math game for students in grades one through eight, offers a free version and a premium version, which costs .95 a month (or less if you purchase a longer subscription). Scholastic offers a “Learn at Home” program that costs .99 a month. There are countless other options, so you might want to search online for educational games related to the subjects your child wants to practice.5. A stress ball to squeezeKids of all ages (and even some adults) can struggle with sitting still and remaining on video for class all day. If your child likes to fidget, you might want to consider buying a large stress ball for them to squeeze with their hands or feet off screen. It can help get out some of their energy so they can stay focused on class. If you search online for “giant stress ball,” you’ll find plenty of options for under .6. Blue-light glassesYou’ve probably heard about the blue light being emitted from computer screens that can irritate eyes and even keep you up at night. To protect your child’s eyes from that stress, or just to make a fashion statement, you might want to invest in some blue-light glasses. They filter out the blue light and also look pretty cool. While some are pricier, plenty of colorful kids’ models are available for or less.7. Fine-tip dry-erase markersTeachers often ask students to hold up their work on dry-erase boards or paper to help keep them on task. Using a fine-tip marker with an eraser tip can make it easier for small hands to fit more numbers or words on their dry-erase board; buying different colors can make it more fun, too. You can find multipacks for under online.8. Trifold poster boardIf your child is easily distracted or working in a room with other people — including other children attending school on different computers — then surrounding their front and side views with a trifold poster board can help them stay focused on class. They can even decorate the poster board with photos and drawings.9. Kid-size headphonesHeadphones can also help cut out distractions, and there are plenty of kids’ headphones on the market for under . If you’re willing to spend a few dollars more for wireless headphones, that can help reduce the temptation to fidget with the wires.More From NerdWalletNo Credit? 3 Steps to Qualify for a Great Credit Card3 Ways to Keep Your Distance With Contactless PaymentsIf Credit Card Relief’s a No-Go, Check Out Debt ManagementKimberly Palmer is a writer at NerdWallet.

An Ohio company that makes bulletproof backpack shields is experiencing an increase in demand for its product due to concerns over school shootings."We've had, I would say, a 100 to 200 percent increase certainly in response," said Matt White, the director of marketing for ShotStop Ballistics, based in Stow.The backpack inserts are one-quarter inch thick and weigh about a pound. It's made from the company's Duritium technology, which can block bullets from handguns and some rifles. However, it does not protect against high-caliber weapons, like AR-15s.The shields come in hard or soft designs and cost 0.White said more parents have been inquiring and ordering the insert following the Feb. 14 school shooting in Parkland, Florida. Demand also increased after a 13-year-old boy died after shooting himself inside a middle school restroom in nearby Jackson Township."The fact that you're even here and we're talking about it, it's terrible," White said. "It's not something that we ever envisioned. It's not something that we had planned for, but the potential with what's out there now, it's one more layer of safety."White said the bulletproof product was originally meant as a clipboard for police officers to provide added protection during traffic stops.Some believe sending kids off to school with the shield only creates more fear and anxiety."It's not right. I mean, come on," said Dave Spearing who has grandchildren in the nearby Cuyahoga Falls School District. "Schools are safe."But Kendall Kubus, a recent Akron Archbishop Hoban High School graduate, sees it differently."I think it's protecting us against if that is a scenario, we have that protection and parents have that in their mind that, "Okay, my child is there. They're going to be safer."' 1819
