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

ANNAPOLIS, Md. — A municipal government in China has donated 40,000 medical-grade face masks to Maryland’s capital city amid the coronavirus pandemic.The donations from Changsha, China, were first offered to Annapolis city officials in April, when the need for the masks among public safety workers was high in the beginning of the pandemic, Annapolis City Manager David Jarrell said in a news release Tuesday.They arrived this month, with one of the boxes featuring strikers of American and Chinese flags with a message that read: “Go, City of Annapolis! Best Wishes from Changsha! True unity inspires people to work as one to overcome adversity,” The Capital Gazette reported.Another note from Yani Xia, a representative in the Chinese city’s Foreign Affairs Office, accompanied the shipments. “We sincerely wish you and everyone in Annapolis continued good health, and the fortitude to persevere during this challenging period,” Xia’s note read.Annapolis’ relationship with Changsha began under a former city administrator, according to the release. The two municipalities are now sister cities. 1106

And then there were three. The Atlantic Coast Conference, Big 12 and Southeastern Conference were still moving forward with plans for a fall college football season. Two other Power Five leagues, the Big Ten and the Pac-12, have called things off. SEC Commissioner Greg Sankey says he is comfortable with the 14-member conference’s approach. The ACC says it will continue to follow advice of medical advisers and health officials. The Big 12 Board of Directors met late Tuesday. According to ESPN sources, the league's administrators are still committed to having a fall season. The league previously announced it would move forward with nine conference games and one nonconference contest for each of its teams. In addition to the Pac-12 and Big Ten, the Mid-American and Mountain West Conferences previously announced they were postponing the start of the 2020 football season. The MAC and MWC are two of five leagues that comprise the "Group of Five," which are the lower tier conferences that are part of the Football Bowl Subdivision. 1049
