The University of Arizona and Boeing joined forces to find disinfectants that will kill COVID-19 and help make air travel safer. The project known as the Confident Travel Initiative is designed to test out cleaning solutions that can destroy the Coronavirus. Arizona microbiology professor Dr. Charles Gerba, who is known as "Dr. Germ," says he’s been working with Boeing since the summer to test cleaning products as part of the initiative to make flying as safe as possible during the pandemic and beyond.“It's really innovative to try to get a coating that will be antiviral," he said. "I think it’s the next step in hygiene and disinfection adding another barrier between when they clean and regularly disinfect aircraft. We’re looking at coatings. And anytime the virus lands on it would kill it, so you don’t have to keep disinfecting all the time."The team conducted laboratory testing by using a virus called MS2 on surfaces inside of an unoccupied plane. The virus has similar characteristics to the virus that causes COVID-19.“It would protect you from when they disinfect it or clean the aircraft. In case the virus lands again on a surface in the aircraft. We’ve been evaluating the overhead bins, the seats, the trays, the handles,” Gerba said.Cleaning solutions and ultraviolet wands were also used throughout the plane and according to Boeing, the results show that antimicrobial coatings were effective for extended periods of time and won’t be harmful to passengers. While Gerba didn’t share the names of the disinfectants, he did say the products can potentially be used on public transportation and other high traffic areas.“We actually did some of the work in the aircraft going in and contaminating certain areas like the tray in the aircraft the overhead bin and then evaluating the disinfectants to show they could kill the virus," Gerba said. "I see this new technology of self-disinfecting surfaces will revolutionize public places in cleanliness, cars, and buses you name it. These are products already on the market and they are new innovative products where you can put down a coating and it will last for hours, weeks, or maybe even months."The research project is expected to be done with other viruses by the end of the year and airplane cleanings will be done between flights.“It all has a big benefit I think it's going to add that extra barrier to me it’s the next generation of infection control and the spread of disease,” Gerba said.This story was first reported by Shawndrea Thomas at KGUN Tucson, Arizona. 2552

The U.S. Marine Corps says it has lifted a "shelter-in-place" order at the Air Ground Combat Center (AGCC) in Twentynine Palms, California following earlier reports of an "active shooter."According to a statement from the Marines, the order was enacted when an "individual" suffered a self-inflicted gunshot wound on the base at about 8:30 a.m. PT. No other injuries were reported. The person who fired the gun has been transported to a local medical center for treatment.The Marines say they are investigating.Shortly after 8:30 a.m., the Marines tweeted that they were "aware of reports" of an active shooter at the AGCC. Later, both KESQ-TV in Palm Springs, California and KTTV-TV in Los Angeles reported — citing a base spokesperson — that a suspect had been taken into custody and that there were no reports of injuries. The Marines later disputed those reports, saying that it could not confirm that a suspect was in custody.The base is located about an hour's drive northwest of Palm Springs. 1008

The Trump administration announced Thursday it is enacting new sanctions on Russia for its election meddling, a month-and-a-half after missing a congressionally mandated deadline.The Associated Press also reports that the administration has accused Russia of an ongoing, deliberate attempt to penetrate the US energy grid.The new punishments include sanctions on the Internet Research Agency, a Russian troll farm that produced divisive political posts on American social media platforms during the 2016 presidential election. Yevgeniy Viktorovich Prigozhin, a financial backer to the Internet Research Agency with deep ties to Russian President Vladimir Putin, is also included.Known as "Putin's chef," Prigozhin was indicted by special counsel Robert Mueller earlier this year for his involvement with the Russian troll farm.In total, the administration applied new sanctions on five entities and 19 individuals on Thursday, including Russians who posed as Americans and posted content online as part of the IRA's attempts to sow discord ahead of the presidential contest.The sanctions were applied through executive power as well as through the Countering America's Adversaries Through Sanctions Act, which Congress initially passed this summer hoping to pressure Trump into punishing Russia for its election interference.Trump signed the bill reluctantly in August, claiming it impinged upon his executive powers and could dampen his attempts to improve ties with Moscow.The measure imposed an October deadline on the administration to produce lists of individuals and entities that could be subject to potential sanctions, and a January deadline to impose them. The law required the administration to identify entities that conduct significant business with the Russian defense and intelligence sectors.The administration missed both by several weeks, claiming necessary work was underway at the State and Treasury Departments to complete the lists.The delay was seen as sign of Trump's unwillingness to punish Russia for its meddling, which he has downplayed in the past. Members of Congress expressed frustration that their law, which passed almost unanimously, wasn't being enacted.On Thursday, administration officials insisted the new measures weren't the end of their efforts to punish Russia."By no means will this constitute the end to our ongoing campaign to instruct Mr. Putin to change his behavior," a senior administration official told reporters.The-CNN-Wire 2485
