The band Smash Mouth is facing criticism for playing a concert to a large crowd that were reportedly mostly mask-less. The band headlined the Sturgis Motorcycle Rally being held this week in South Dakota.Images from Sunday night’s Smash Mouth concert show a crowd packed shoulder to shoulder in some places, with few people wearing masks.At one point in the concert, a band member addressing the crowd can be heard saying "F*** that Covid s***,” according to KOTA-TV. It's unclear what he's saying before or after that comment.The group defended the concert in a statement given to Billboard; band manager Robert Hayes said "the promoter did a fantastic job with their COVID protocol. They had a very strict social distancing and mask policy in place for all workers."Hayes added comments about the "endless hours" spent to ensure the concert happened as safely as possible and “we are very happy with the outcome."Sturgis city officials allowed the annual event to go on this year, despite pleas from residents, and recommend visitors wear masks and social distance. However, masks are not required.Numbers from the South Dakota Department of Transportation indicate attendance numbers are similar to 2019 for the first few days:Friday, August 7: 49,835 entering – down 4.3% from Friday last yearSaturday, August 8: 54,804 entering – down 8.0% from Saturday last yearSunday, August 9: 56,149 entering – up 1.1% from Sunday last yearThis is the 80th year of the Sturgis Motorcycle Rally. In recent years, the event has drawn between 500,000 and 700,000 people. 1568

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

TAMPA, Fla. — Many parents are opting to keep their kids home to give distance learning a try amid the pandemic.With many districts pushing back the first day of school, you got time to get in line."Now that we have time to plan it’s a beautiful thing," Anne Flenner with Florida Virtual School said.She recommends parents making a dedicated space for your child. It can be a desk, the kitchen table, or an empty guest room.You also want to get them involved in making the space functional."Whether that’s adding some posters that inspire them or whether it’s just getting color-coded notebooks that they’re going to use," Flenner said. "That actually can bring some excitement for them for this new school year when it’s a really hard time for them."Once you got that figured out, it is time to set up what Flenner calls a “pace chart.” It’s basically the agenda your kid is familiar with, but for you too. Some parents put it on a big whiteboard or just a piece of paper attached to the fridge."Parents can really do that important part of organizing them so that they can really focus on their job which is to learn the content," Flenner said.She also suggests after getting access to the virtual learning platform, go in and click on everything. Then, organize different binders or folders for each course.If your kids are sharing devices with each other or you, make a folder on the desktop for their own work. Or buy each child their own flash drive."The biggest help that will get you in gear for virtual learning… is to throw out what you know about the traditional school day. We call it chunking their time together," Flenner said. "Most students will work three to four hours like on one course alone to get everything done before they move on."Flenner and the crew at Florida Virtual School have been doing this for more than 20 years. They are professionals and they understand we are far from that. And that is okay."I want to tell parents to take a deep breath and do the best you can," Flenner said.This story was originally reported by Jasmine Styles at WFTS. 2084

Sudan, the world's last male northern white rhino, has died.For nearly a decade, Sudan lived in a 700-acre enclosure at the Ol Pejeta Conservancy, against the backdrop of the hulking Mount Kenya.Armed guards protected him 24 hours a day because he belonged to a subspecies on the verge of extinction from poachers. Rhinos are targeted by poachers fueled by the belief in Asia that the horns cure various ailments. 421
