The U.S. Food and Drug Administration updated its guidance on face coverings on Tuesday, adding information about wearing expired surgical masks.According to the FDA, face and surgical masks may still offer protection even if they've passed their designated shelf life or expiration date."If there is no date available on the face mask label or packaging, facilities should contact the manufacturer. The user should inspect all masks before use and, if there are concerns such as degraded materials (such as elastic) or visible tears," the agency recommends that you should discard the product.However, when it comes to re-using surgical disposal masks, the CDC recommends discarding them after one use.You can clean reusable masks, the CDC says, and recommends washing them after each use. For N95s, which the CDC considers a one-time-use product, but can be re-worn if cleaned with an approved decontamination method. 927

The school shooting was over in seconds. But it could have dragged on longer and proven deadlier were it not for the rapid response of a school resource officer.When a 17-year-old gunman walked into Maryland's Great Mills High School on Tuesday, the swift action of the school's sole resource officer, Blaine Gaskill, was instrumental in bringing the incident to a quick end.Gaskill's response was hailed as an example of exactly what a resource officer is supposed to do in such a circumstance, particularly when contrasted to the actions of the security officer in last month's shooting in Parkland, Florida. (In the incident at Marjory Stoneman Douglas High School on February 14, the armed school resource deputy waited outside the school building as the shooter gunned down students inside.)"He responded exactly how we train our personnel to respond," St. Mary's County Sheriff Tim Cameron told reporters.Engaging the shooterAs soon as the gunfire began, Gaskill rushed to the scene. He fired a round at the shooter, who also fired a round at the same time, Cameron said.It's not yet clear whether the shooter, Austin Wyatt Rollins, was felled by the officer's bullet or killed himself."DFC [Deputy First Class] Gaskill fired at the shooter ... almost simultaneously as the shooter fired," Cameron said. "This is something we train, practice and in reality, hope would never come to fruition. This is our worst nightmare."Gov. Larry Hogan called Gaskill "a very capable school resource officer who also happened to be a SWAT team member.""This is a tough guy who apparently closed in very quickly and took the right kind of action," he said. "And while I think it's still tragic, he may have saved other people's lives."Over in secondsThe incident began in a school hallway at 7:55 a.m., just before classes started. Authorities say Austin, armed with a handgun, shot a female student, with whom he had a prior relationship, and another male student.Gaskill responded to the scene in less than a minute, the sheriff said.Cameron said the entire incident took less than a minute, possibly seconds.The 16-year-old female student is in critical condition with life-threatening injuries, and the 14-year-old male student who was shot is in stable condition.Gaskill was unharmed."He's doing well and we're going to do everything to support and promote him and his well-being," Cameron said.Playing to a narrativeGaskill's actions were praised, rightly, across social media. But some -- most notably, the NRA -- held him up as an example of the "good guy with a gun" theory. The theory goes, that bad guys will always find a way to circumvent whatever gun laws are in place. And "to stop a bad guy with a gun," as NRA head Wayne Lapierre?said, "it takes a good guy with a gun.""This [Great Mills High School] armed school resource officer, you're not hearing anyone in #MSM talk about it because it disrupts their narrative," NRA spokeswoman Dana Loesch said in one of several tweets Tuesday. (MSM is short for mainstream media.)So far, this year, there have already been 17 school shootings where someone was hurt or killed.In the Parkland shooting, school resource deputy Scot Peterson never entered the building after taking a position outside. He resigned after he was suspended without pay for his inaction."Had our resource officer taken action immediately, the result of the Stoneman Douglas Valentine's Day Massacre would have been different," Parkland student Kai Koerber told CNN."We might not have had to walk over the bodies of our classmates, once lovely and wonderful people, as we were led away from murderous tragedy."Speaking to reporters, Dr. James Scott Smith, the superintendent of St. Mary's County's public schools, put the senselessness of it all in perspective."It looks as though the SRO [school resource officer] did exactly what the SRO is trained to do, and yet we still have a tragic loss of life," he said. "We still have somebody in critical condition. And we have students at the school and staff at the school impacted." 4086

The University of Washington’s Institute for Health Metrics and Evaluation now projects that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.The IHME released the updated model on Wednesday.The IHME’s coronavirus projections have been frequently cited in the past by the White House’s coronavirus task force. The group uses state data along with other metrics to create projections on the number of coronavirus-related deaths throughout the US.The projection state that the US is currently on track to have an additional 58,000 coronavirus-related deaths between now and October 1. But that number drops to just 23,000 if masks are universally worn in public. Those figures are on top of the over 121,000 reported coronavirus-related deaths since the beginning of the pandemic.The IHME’s model projects that the US death toll will stay consistent on a per-day basis between now and September, before starting to increase in the fall. But the model projects that fewer than 100 Americans will die per day from coronavirus by September if masks are worn.The IHME’s latest model projects that coronavirus-related deaths will continue to surge in the states of Texas, Arizona and Florida in the coming weeks, while leveling or dropping off in many other states.To see a state-by-state breakdown of the IHME’s projections, click here.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective. 1701

The UK will expel 23 Russian diplomats from the country after concluding that the Russian state is responsible for the attempted murder of former Russian spy Sergei Skripal and his daughter Yulia in the English city of Salisbury.This will be the single biggest expulsion of Russian diplomats in over 30 years, Prime Minister Theresa May said Wednesday. The 23 concerned, who May said had been identified as undeclared intelligence agents, will have only one week to leave."For those who seek to do us harm, my message is simple. You are not welcome here," she said in a statement to the House of Commons following a meeting of Britain's National Security Council.The expulsion of diplomats will "fundamentally degrade" Russian intelligence capabilities in Britain for years, May said.The Skripals are critically ill in hospital after being exposed to the nerve agent, known as Novichok and developed in Russia, on March 4. Thirty-eight other people in Salisbury were seen by medics after the exposure. One, a police officer, remains hospitalized.May said Monday it was highly likely that Moscow was behind the poisoning. The Russian ambassador to the UK was summoned to the UK Foreign Office to explain whether the attack was directed by Russian authorities, or whether Moscow had lost control of the nerve agent.She demanded that Moscow respond by midnight Tuesday, London time, to the UK government's conclusion that Russia was linked to the poisoning of Sergei Skripal and his daughter Yulia on a park bench in Salisbury in southern England.But Moscow -- which has repeatedly dismissed any accusations of involvement in the attack -- ignored the deadline.  1672

The success of online retailers such as Amazon is proof positive that people like shopping online, but many parents still prefer going to the actual store for their children's back-to-school supplies.That way, they have their items right away, and their children can see and hold their new supplies themselves. Who's getting the better deal, though? People who frequent Amazon, or those who head to physical stores such as Target and Walmart?We priced a basket of items for a third-grade classroom, including pencil sharpeners, Crayola colored pencils, Elmer's school glue, Expo markers and Ticonderoga pencils.And we can't forget that oh-so-cute Disney backpack. 691
