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 Smithsonian announced the reopening of two prominent Washington, D.C., area attractions that have been shuttered during the spread of the coronavirus.The National Zoo located in Washington and the National Air and Space Museum in nearby Chantilly, Virginia, are scheduled to reopen Friday with a number of safety precautions in place. All other Smithsonian attractions will remain closed. Most other prominent D.C. destinations, including the White House and Capitol, also remain closed to visitors.Both at the zoo and the National Air and Space Museum, all visitors age 6 and over will be required to wear face coverings. The zoo and museum are also requiring timed tickets, and has scaled back its hours to close at 4 p.m.“As a public entity, we thrive on serving our visitors and making our collections readily available to them, virtually and in person,” said Lonnie Bunch, Secretary of the Smithsonian. “However, the safety and well-being of our staff, visitors and volunteers come first and are paramount, so we are taking a deliberate, phased and cautious approach to reopening. Our goal is to be safe and measured in order to adjust and pivot as necessary.” 1177

The view from the airplane window just got a little bit weirder -- or at least it did over Ireland.Several airborne sightings of at least one "very bright" unidentified flying object were seen last Friday, according to air traffic control audio logs.Chatter between airline pilots and Irish air traffic control focused briefly on the sightings, with at least four aviators confirming that they'd seen the phenomenon.The exchange began when one pilot asked Shannon air traffic control if there was nearby military activity. When the air traffic controller replied in the negative, the pilot said that she had seen something moving "so fast.""It came up on our left hand side (rapidly veered) to the north, we saw a bright light and it just disappeared at a very high speed ... we were just wondering. We didn't think it was a likely collision course .. (just wondering) what it could be," she said.A pilot on Virgin Flight 76 added that his flight crew had seen "two bright lights at 11 o'clock (which) seemed to bank over to the right and then climb away at speed." 1073

The U.S. again broke its daily record for new confirmed cases of COVID-19 on Wednesday, as local health departments recorded 50,000 new confirmed cases of the virus, according to a database kept by Johns Hopkins.The previous record was set Tuesday when health departments reported about 45,400 new cases.The figures highlight a continued spike in cases throughout the country over the past few weeks. Prior to the recent peak, the highest daily increase in confirmed cases came on April 24, when health departments reported about 36,400 new cases. The U.S. has recorded at least 38,900 new cases every day for the last week.(John's Hopkins)Because the Johns Hopkins database is reliant on reporting from local health departments, the data doesn't necessarily reflect a patient's day of infection. Daily case numbers are often higher mid-week because some local health departments or test centers may be closed on weekends.It's not just cases that are on the rise. According to the Institute for Health Metrics and Evaluation at the University of Washington, use of hospital beds, ICU beds and invasive ventilators have all risen in recent weeks after months of falling resource use.Many states have either "paused" or chosen to take steps back in their reopening process as cases and hospitalizations linked to the virus continue to rise.On Tuesday, Dr. Anthony Fauci — the government's top expert on infectious diseases — called the recent spike in cases "disturbing," and said that he could foresee the U.S. reporting up to 100,000 new COVID-19 cases a day if recent trends continue. 1593

The U.S. population grew by the smallest rate in at least 120 years from 2019 to 2020.Figures released Tuesday by the U.S. Census Bureau show the U.S. population grew by 0.35% from July 2019 to July 2020, an increase of 1.1 million people in a nation with an estimated population of more than 329 million residents.Demographer William Frey says population growth in the U.S. already had been stagnant over the past several years due to immigration restrictions and a dip in fertility.However, the pandemic exacerbated that lethargic-growth trend.Even during the height of the Spanish flu, the growth rate was higher — 0.49%. 632
