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

Arizona Sen. John McCain, a former Republican presidential nominee and prisoner of war, has died after a battle with an aggressive form of brain cancer.The 30-year Arizona Senator leaves behind wife, Cindy, and 7 children.John Sidney McCain III, 81, was the son and grandson of Navy admirals. He was born August 29, 1936.As a naval pilot, he narrowly escaped death in a fire aboard the USS Forrestal in 1967. Also in 1967, McCain's plane was shot down over Hanoi, and he was captured by North Vietnamese troops. He was tortured during more than five years as a prisoner of war.RELATED:?50 photos that capture John McCain's personalityCelebrity deaths of 2018: Remembering those we've lost this yearAfter retiring from the Navy in 1981, he moved in Arizona and ran for Congress, winning a U.S. House seat the following year.After two terms, he was elected to the U.S. Senate, succeeding Barry Goldwater, and served in the role until his death.McCain married Cindy Hensley, his second wife, in 1980. She is the daughter of an Arizona beer distributor.McCain is father to seven children, including Bridget, a daughter adopted from Bangladesh. Another daughter, Meghan McCain, is a television host on ABC’s The View.A low point in his political career came when McCain was implicated in the Keating Five campaign contribution scandal of the 1980s. The senator emerged with a new passion to reform money in politics. Called a maverick, he bucked his party as he worked with Democrats on campaign finance and other issues.McCain also campaigned for president in 2000 and 2008. In 2008, he won the Republican nomination with a surprising choice of running mate, then-Alaska Gov. Sarah Palin.After his second failed presidential bid, McCain continued as senator, assuming the role of an elder statesman. He visited troops overseas and dug into foreign policy. McCain, due to the lasting impacts of his torture as a POW, could not lift his arms above his head. He had other health scares, including bouts of skin cancer that left a large scar on his cheek. In July 2017, Sen. McCain was diagnosed with glioblastoma, the deadly brain cancer which took his life.Even in his waning days, McCain lived up to his reputation as a maverick. In August 2017, less than two weeks after surgery to remove his tumor, McCain returned to the U.S. Senate floor to become the deciding "no" vote on repealing Obamacare.Senator McCain had a joke he famously told throughout his life. Whenever he got upsetting news, he said he slept like a baby, explaining that he slept two hours, woke up and cried, then slept two more hours and did the same. It’s that wit that many of his closest friends say they’ll remember him by in the days ahead.No funeral arrangements have been announced, but in an interview with “60 Minutes”, Senator McCain recently said he wanted the ceremony to take place at the Naval Academy in Maryland.  2913
