ANNAPOLIS, Md. – The U.S. Naval Academy has named its first ever African American female brigade commander – Midshipman 1st Class Sydney Barber.The brigade commander is the highest leadership position within the student body and it’s held for a semester. Barber will hold the role this spring semester.Barber will be the 16th woman selected for brigade commander in the 44 years women have been attending the Naval Academy. The first female brigade commander was in the class of 1992.“Earning the title of brigade commander speaks volumes, but the title itself is not nearly as significant as the opportunity it brings to lead a team in doing something I believe will be truly special,” said Barber. “I am humbled to play a small role in this momentous season of American history.”Barber is from Lake Forest, Illinois, and is majoring in a mechanical engineering, with aspirations of commissioning as a Marine Corps ground officer.As a walk-on sprinter and hurdler of the Navy Women’s Varsity Track and Field team, Barber has lettered all three years of competing and is a USNA record holder for the outdoor 4x400m relay.Word of the announcement spread quickly after a social media post by the first Black female to graduate from USNA, Janie Mines. She wrote, “This brought me to tears. This young woman, Midshipman Sydney Barber, will be the first Black Female Brigade Commander at the U.S. Naval Academy. 40 years later. Thank you, Sydney! Love you!” 1460

Amid the coronavirus pandemic, Thanksgiving this year is bound to look a bit different than in years past.When it comes to holiday gatherings, the Centers for Disease Control and Prevention (CDC) recommends you eat with people you already live with by having a small dinner or having a virtual feast.According to Numerator, a market research firm, 70% of Americans polled that they were doing Thanksgiving differently this year.According to the New York Times, consumer surveys by Butterball and Hormel Foods also saw its customers celebrating the holiday with smaller gatherings.In turn, this has many grocery store chains approaching the holiday differently by selling smaller turkeys this year to accommodate consumers.According to CNN, chains like Walmart, Giant Eagle, and Stew Leonard's are either selling smaller birds or boneless turkey breasts. 861

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
