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

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

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

Antwone Berry was found shot and killed in January in Milwaukee, two weeks after he went missing.Milwaukee police say 34-year-old Skylard Grant is accused of killing Berry. According to police and family members, the two were close friends around each other a lot. That's why this killing is senseless to them.“It's just ridiculous, to come to find out that someone that's very close to you and be the one to hurt you," said Tashe Lee, Berry’s cousin."He didn't deserve that, you know that was the wrong thing," said Steve Lee, another cousin.Berry went missing on Christmas Eve, for two weeks his family searched all over for him in the cold.He was found shot to death two weeks later on Jan. 7 in a wooded area in Milwaukee.According to the criminal complaint, witnesses say Grant was drunk and began arguing with Berry about not sending him money when he was previously in jail.Grant allegedly shot and killed Berry with his own gun. Grant tried to then sell Berry's gun to another friend, who declined and asked of Berry's whereabouts. Court documents show that's when Grant said."....you ain't gonna be seeing him no more, I had to take care of him," he allegedly said. "That wasn't fair to him it wasn't fair to us for somebody to be getting taken away from us," Tasha Lee said.  "Just hoping for the best, hope that he gets life, that’s what I want for him to have life, he took my cousin's life, he deserve to have life."Grant was actually arrested for this case on Jan. 4. Investigators analyzed phone records placing grant near the area where berry's body was found. Surveillance video also showed Grant's SUV near the scene the day Berry went missing.Homicide numbers from Milwaukee Police for this year indicate that of 32 homicide cases so far in Milwaukee this year, 14 remain open. 1834
