Swishing with mouthwash can help freshen that mask breath, and, new research suggests, reduce the amount of coronavirus in the mouth and may help reduce the spread of the virus.Physicians and scientists at the Penn State College of Medicine studied the effect of rinsing with a neti pot, peroxide sore-mouth cleansers, mouthwashes and a 1 percent solution of baby shampoo, which is often used by head and neck doctors to rinse the sinuses. All of the products are currently available to consumers, many over-the-counter.They found several of the nasal and oral rinses had “a strong ability to neutralize human coronavirus, which suggests that these products may have the potential to reduce the amount of virus spread by people who are COVID-19 positive,” the college said in a written statement.Researchers used human coronaviruses that are similar to SARS-CoV-2, the coronavirus strain that causes COVID-19. The “outer envelopes of the human coronavirus tested and SARS-CoV-2 are genetically similar,” the researchers stated.“While we wait for a vaccine to be developed, methods to reduce transmission are needed,” said Craig Meyers, the professor who led the study. “The products we tested are readily available and often already part of people’s daily routines.”The study looked at the effectiveness of the various products when they interact with a solution containing a strain of human coronavirus at intervals of 30 seconds, one minute and two minutes.The 1 percent baby shampoo solution inactivated more than 99.9 percent of the human coronavirus after being in contact for two minutes. The mouthwash and gargle products were also 99.9 percent effective in inactivating the human coronavirus, but after only 30 seconds of contact.The findings from Penn State College of Medicine add to findings earlier this year that showed certain types of oral rinses could inactivate SARS-CoV-2.Meyers said the next step in this line of research is to evaluate products like mouthwashes in COVID-19 positive patients to see if they reduce the viral load.The study’s results were published this week in the Journal of Medical Virology. 2137

Texas State University moved to suspend all fraternity and sorority activities Tuesday, a day after a 20-year-old fraternity pledge died following an off-campus social event.San Marcos police said they were called at 11:35 a.m. Monday to respond to a person not breathing at an apartment complex. Matthew Ellis, a pledge for the Phi Kappa Psi fraternity, was found unresponsive and declared dead less than an hour later. Police said he was discovered by friends just after 11 a.m.An autopsy is being conducted, but a preliminary investigation indicates alcohol may have been a factor in his death, police said. 618

  

TAMPA, Fla. - A "Back the Blue" mural was painted outside the Tampa Police Department headquarters over the weekend.On Saturday, about 40 people came together and painted the mural on East Madison Street in downtown Tampa. The mural was created to show support for law enforcement."When they walk into the police department or when they go to work or they're patrolling the streets, they see that mural and they know they have a community behind them," said Cassandra Kistler.Kelli Campbell and Cassandra Kistler are members of Back the Blue Florida. The ladies helped organize the project.People from Community Patriots of Tampa also helped paint the mural."We had people just walking by that were inspired to pick up a brush and a roller and start helping us," said Campbell.Some people on social media are criticizing the mural or showing their support."We've been criticized a lot like it's not the best, it's not this, it's not that. It's community and community did it and brought it together and made it happen," said Cassandra Kistler.A Change.org petition said, "This mural seems to mock the Black Lives Matter movement and is a huge slap in the face for all the protesting we have been doing all over this country.""Everybody's entitled to voice their opinions and voice what they want," said Kistler."This has nothing to do with race. This is not against anyone. It's not to counter anyone. This is 100% showing support for law enforcement, all branches and truly all first responders," said Campbell.A City of Tampa spokesperson said the mural was not approved by the city.“Any tribute to honor their service is welcome. It’s unfortunate they didn’t see the permitting process through so that our community could participate in showing their appreciation for the brave men and women that service our residents every day," said Mayor Jane Castor.Kistler claims the group got verbal approval from Mayor Castor's office.This article was written by Julie Salomone for WFTS. 1989

  

Stephen Hawking, the brilliant British theoretical physicist who overcame a debilitating disease to publish wildly popular books probing the mysteries of the universe, has died, according to a family spokesman. He was 76.Considered by many to be the world's greatest living scientist, Hawking was also a cosmologist, astronomer, mathematician and author of numerous books including the landmark "A Brief History of Time," which has sold more than 10 million copies.Celebrity deaths of 2018: Remembering those we've lost this yearWith fellow physicist Roger Penrose, Hawking merged Einstein's theory of relativity with quantum theory to suggest that space and time would begin with the Big Bang and end in black holes. Hawking also discovered that black holes were not completely black but emit radiation and would likely eventually evaporate and disappear."A star just went out in the cosmos," Lawrence Krauss, a theoretical physicist and cosmologist, wrote on Twitter. "We have lost an amazing human being."Hawking suffered from ALS (amyotrophic lateral sclerosis), a neurodegenerative disease commonly known as Lou Gehrig's Disease, which is usually fatal within a few years. He was diagnosed in 1963, when he was 21, and doctors initially only gave him a few years to live.The disease left Hawking wheelchair-bound and paralyzed. He was able to move only a few fingers on one hand and was completely dependent on others or on technology for virtually everything -- bathing, dressing, eating, even speech.Hawking used a speech synthesizer that allowed him to speak in a computerized voice with an American accent."I try to lead as normal a life as possible, and not think about my condition, or regret the things it prevents me from doing, which are not that many," he wrote on his website."I have been lucky that my condition has progressed more slowly than is often the case. But it shows that one need not lose hope."Hawking was married twice. He and his first wife, Jane Wilde, wed when he was still a grad student and remained together for 30 years before divorcing in 1995. Hawking was later married for 11 years to Elaine Mason, one of his former nurses.Hawking was born in Oxford, England, on what turned out to be an auspicious date: January 8, 1942 -- the 300th anniversary of the death of astronomer and physicist Galileo Galilei.In an exclusive interview with CNN in October 2008, Hawking said that if humans can survive the next 200 years and learn to live in space, then our future will be bright."I believe that the long-term future of the human race must be in space," Hawking told CNN's Becky Anderson."It will be difficult enough to avoid disaster on planet Earth in the next 100 years, let alone next thousand, or million. The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load."At Cambridge, he held the position of Lucasian Professor of Mathematics -- the prestigious post held from 1669 to 1702 by Sir Isaac Newton, widely considered one of the greatest scientists in modern history.Yet Hawking once said if he had the chance to meet Newton or Marilyn Monroe, he would opt for the movie star.Hawking became a hero to math and science geeks and pop culture figure, guest-starring as himself on "Star Trek: The Next Generation" and "The Simpsons." His life was dramatized in the 2014 movie, "The Theory of Everything."He had at least 12 honorary degrees and was awarded the CBE in 1982. A CBE, or Commander in the Most Excellent Order of the British Empire, is considered a major honor for a British citizen and is one rank below knighthood.Despite being a British citizen he was awarded the Presidential Medal of Freedom, the US's highest civilian honor, in 2009 by President Barack Obama.In September 2016 Hawking joined 375 "concerned" scientists in penning an open letter criticizing then-presidential candidate Donald Trump, citing the threat of climate change and blasting his push for the US to leave the Paris Accord.Fellow scientists hailed Hawking for his work and influence in the field."His passing has left an intellectual vacuum in his wake," tweeted Neil deGrasse Tyson. "But it's not empty. Think of it as a kind of vacuum energy permeating the fabric of spacetime that defies measure."Hawking leaves behind three children and three grandchildren. "We are deeply saddened that our beloved father passed away today," Hawking's children, Lucy, Robert and Tim, said in a statement. "He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humor inspired people across the world.""He once said, 'It would not be much of a universe if it wasn't home to the people you love.' We will miss him forever."The-CNN-Wire 4846
