As mandatory face coverings become more and more common, keep in mind, some are better at protecting from viruses than others.When issuing their face covering guidelines, San Francisco specifically called out masks with one-way valves designed for “easier breathing”, warning that they allow for droplets to get out of the mask and potentially endanger others nearby. These valves are usually about the size of a coin on the side of the mask.The CDC, and many other health departments and officials, urge wearing a mask to prevent the spread of the coronavirus because it can be spread through respiratory droplets. Those droplets are produced into the air when an infected person coughs, sneezes, talks, sings, chants, shouts, etc. They can then land on other people nearby or be inhaled by others.The CDC recommends people wear a cloth face covering in public settings, to reduce the transmission of droplets into the air.“There are no high quality studies regarding the use of masks with additional types of various filters placed in them or with ‘breathing valves.’ While widely marketed with various claims, these have not been studied at all and it is unclear if they help or hurt the overall filtration efficacy against microorganisms,” read a statement from Marc Sala, M.D., Assistant Professor of medicine in the Division of Pulmonary and Critical Care at Northwestern University’s Feinberg School of Medicine.People are being asked to leave N95 masks (without a valve) and surgical masks available for medical staff and essential personnel who are coming into daily contact with many infected patients.An N95 mask with an exhalation valve is not recommended because unfiltered air is sent through the valve and into the air, potentially carrying coronavirus droplets. “The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained…” according to the CDC’s website.Dr. Sala said testing has shown things like multiple layers of cotton fabric is better than a single layer, material of a higher thread count is more effective, and overall, “these studies emphasized the notion that if a mask doesn’t have a good fit (has gaps) its effectiveness is dramatically reduced.” Dr. Sala said even if the cloth mask is not ideal, it can still play a major role in preventing illness as more masks are worn by the population as a whole.Bottom line, choose a fabric face covering that fits and is comfortable around your ears or head, and keep it on while in public, especially when social distancing is not possible, to protect you and the people around you. 2864

ANAHEIM (CNS) - Thousands of Disneyland enthusiasts lined up early Friday to experience the theme park's newest Star Wars Land ride.Bobby Navarro of Garden Grove said he got up at 4 a.m. with his friends and got into the park by 5:30 a.m.Navarro experienced Star Wars: Rise of the Resistance when it debuted at Disney World on Dec. 5, so he had some practice in using the company's application to sign up for a pass to the attraction. Navarro said it was key to get everyone in the group connected on the app and requesting a pass simultaneously, but that also meant he had to de-select others who were not at the park with his group.RIDE REVIEW & VIDEO: 'Rise of the Resistance' fulfills missing 'Star Wars' feel at Galaxy's Edge"The queue for the digital app started at 6 o'clock... and we still had to wait hours before the app opened," Navarro said. "And then, it was whoever is able to push the button fastest."Navarro and his group were assigned to boarding group 84, and he was advised the park may only be able to handle 82 boarding groups on Friday, but he was hopeful his group will get a chance to see the Anaheim version of the ride."The first day in Florida, they got up to boarding group 125," Navarro said."We're close to group 50 now," he said about 1 p.m.Navarro said even the wait in line for the ride in Florida helped guests feel immersed in the experience. The attraction included a hologram explaining the "context and storyline," he said.RELATED: California Adventure's 'Avengers Campus' set for summer 2020 openingCast members help guide guests through the line until the fun begins with an abduction and imprisonment by stormtroopers, he said.One of the more impressive attractions is a glass panel that makes participants feel as if they are looking into outer space, he said.As the "prisoners" are being told they will be "eliminated," resistance fighters break through with lightsabers to help lead an escape, Navarro said."They tell you, `Hurry up, get out,"' Navarro said.RELATED: Disneyland tickets are on sale for as low as right nowThe guests make their escape on a pod, he said."The mag-lev system is what really makes the ride," he said of the battleship in the attraction. "This really feels like a battleship.""They really did a great job of transporting you to a different place," he said.The ride takes about 20 minutes, he said.Anaheim police Sgt. Shane Carringer said the city has not experienced any issues with traffic in the area despite also hosting the National Association of Music Merchants convention."I haven't heard of any problems," he said. "These large events, although extraordinary for Anaheim, are definitely not out of our comfort zone to handle these pretty regularly. And Disney has ingress and egress down to a science."Carringer said he got to experience the new attraction last night."It was cool," he said. "My wife enjoyed it too." 2912

Are Apple's glory days behind it? That's probably a stretch. But Wall Street clearly is getting more worried about the company's reliance on the iPhone to generate sales and profit at a time when demand for the newer phones appears to be subpar.Shares of Apple (AAPL) fell 3% Wednesday and that was one of the big reasons why the Dow, which includes Apple, fell 300 points. Apple's stock briefly dipped into bear market territory, meaning it was down more than 20% from its all-time high.The reason for the Apple slide? Several companies that produce chips and other components used in iPhones have all issued gloomy forecasts recently, citing sluggish demand for higher-end smartphones.Although none of these companies, which include Qorvo (QRVO), Lumentum (LITE), Japan Display and IQE, have named Apple as the source of their woes, they are all Apple suppliers.But it may not be time to throw in the towel on Apple just yet, even though some analysts are cutting their price targets and earnings estimates due to concerns about soft sales for the newer iPhone XR, iPhone XS and iPhone XS Max.Apple's stock is still up more than 10% this year, making it one of the better performers in the Dow. The company is still worth nearly 0 billion. It remains the most valuable company in the world.Apple also continues to pay a solid dividend that yields 1.5% -- and the company is likely to keep raising its dividend thanks to its cash stockpile of 7.1 billion.What's more, Apple's earnings are expected to increase by more than 13% this fiscal year and keep growing at about a 12% clip annually, on average, for the next few years.So predictions of an Apple iPocalypse, if you will, may be premature. But it does seem like the company needs a new product to get consumers and investors excited again.Perhaps Apple needs to take a cue from the movie "This Is Spinal Tap" and release a new iPhone that goes to eleven. But would it be the iPhone 11 or iPhone XI? 1969

  

An Alabama woman says the temporary teeth that she wore with her zombie Halloween costume almost turned into permanent teeth.Anna Tew of Mobile County, Alabama told WKRG-TV she was forced to schedule an emergency dentist appointment after the "Devil Teeth" she wore with her costume wouldn't come out after nearly a day.Tew said she bought the fake teeth at Walmart to wear with a zombie costume as part of a haunted house at a local school. The teeth came with an adhesive that she applied before putting them in her mouth.But soon after leaving the haunted house, Tew realized the teeth wouldn't budge. On top of that, the teeth were extremely painful, meaning she couldn't eat or drink.At one point, Tew thought that drinking hot coffee would loosen the adhesive, but she told the Ledger-Enquirer that she ended up "drooling" the drink. 850

  

An Arkansas sheriff's office has arrested a woman who helped her boyfriend escape from the county jail last month by posing as a deputy from California.Maxine Feldstein, 30, was arrested Aug. 17 in connection with forgery, accomplice to third-degree escape and criminal impersonation.Feldstein's boyfriend, Nicholas Lowe, was at the Washington County Detention Center on July 27 with a hold for criminal impersonation out of Ventura, Calif., according to a probable cause affidavit.Feldstein, who had bonded out earlier that day, called Washington County jail staff and identified herself as deputy "L. Kershaw" with the Ventura County Sheriff's Office. She also provided a forged VCSO document releasing the agency's hold on Lowe.Jail staff learned of the forgery and accidental release two days later, when a VCSO deputy called to say he was on his way to pick up Lowe.The sheriff's office discovered through jail video that Lowe told Feldstein to pose as a VCSO deputy while she visited him, according to the affidavit.Lowe said Feldstein should tell Washington County that VCSO was "having issues with overcrowding and all low-priority extraditions have been suspended," according to the affidavit.Washington County later confirmed the VCSO document Feldstein used was fake, and that VCSO didn't have a deputy named "L. Kershaw," according to the affidavit.Lowe was also arrested Friday and faces a felony charge of second-degree escape.A spokeswoman for the sheriff's office said the agency is "still evaluating to determine the best corrective action needed to ensure this doesn't happen again.""There is a procedure to ensure requests are legitimate, and that hasn't changed," she said.Feldstein and Lowe were being held Tuesday (Aug. 21) at the Washington County Detention Center on bonds of ,500 and ,000, respectively.The pair has hearings set for Sept. 5 in Washington County Circuit Court. 1920
