An isolated Amazon tribe with no known contact with the outside world has been spotted by a drone flying over the Brazilian jungle, according to the country's National Indian Foundation.Footage released this week shows several people walking through a wide clearing made in a patch of dense jungle in the Javary River valley, near the border with Peru.One of the figures is carrying a spear or pole of some kind, while four or five others stand near what look like thatched structures.None of the people spotted by the drone appear to notice their observer, which is flying high above the trees surrounding them. 620

An independent news organization has researched reports regarding the size of airplane seating, and its findings led it to call coach-class seating a "death trap."The Daily Beast says dense, shrunken seat space does not do a safe enough job of allowing passengers to move quickly in the event of emergencies. DB's investigation found the FAA nor Boeing is disclosing evacuation test data "for the newest (and most densely seated) versions of the most widely used jet, the Boeing 737."It also found tests to ensure all passengers may safely leave a cabin are "dangerously outdated." They do not reflect how densely packed coach class seating has become, the report says."No coach class seat meets the Department of Transportation's own standard for space required to make a flight attendant's seat safe in an emergency," the DB reports. And a judge in a case brought by the Flyers Rights activist organization said there is "plausible life-and-death safety concern" about the "densification" of coach seating.The Daily Beast's report says that court "complained that the FAA had used outdated studies to argue that no change was needed" for how tests are performed, and it refused to release results of tests.The DB looked at 900 pages of Department of Transportation documents; go here to see its full report. 1327

An Ohio company that makes bulletproof backpack shields is experiencing an increase in demand for its product due to concerns over school shootings."We've had, I would say, a 100 to 200 percent increase certainly in response," said Matt White, the director of marketing for ShotStop Ballistics, based in Stow.The backpack inserts are one-quarter inch thick and weigh about a pound. It's made from the company's Duritium technology, which can block bullets from handguns and some rifles. However, it does not protect against high-caliber weapons, like AR-15s.The shields come in hard or soft designs and cost 0.White said more parents have been inquiring and ordering the insert following the Feb. 14 school shooting in Parkland, Florida. Demand also increased after a 13-year-old boy died after shooting himself inside a middle school restroom in nearby Jackson Township."The fact that you're even here and we're talking about it, it's terrible," White said. "It's not something that we ever envisioned. It's not something that we had planned for, but the potential with what's out there now, it's one more layer of safety."White said the bulletproof product was originally meant as a clipboard for police officers to provide added protection during traffic stops.Some believe sending kids off to school with the shield only creates more fear and anxiety."It's not right. I mean, come on," said Dave Spearing who has grandchildren in the nearby Cuyahoga Falls School District. "Schools are safe."But Kendall Kubus, a recent Akron Archbishop Hoban High School graduate, sees it differently."I think it's protecting us against if that is a scenario, we have that protection and parents have that in their mind that, "Okay, my child is there. They're going to be safer."' 1819

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

Are you participating in Black Friday shopping this week? The season's biggest shopping event of the year might look a lot different than usual with many cities, states and retailers putting in restrictions due to COVID-19.For the first time, Deloitte’s consumer survey found that more shoppers plan to go online Thanksgiving weekend than to visit in-person retailers. The survey found that 58% of those planning to shop on Thanksgiving weekend will do so online, compared to 41% who say they will shop in person. Last year, 61% of shoppers said they planned on shopping in person compared to 51% who said they would shop online. A number of those surveyed said they would do both.If you plan on shopping on Black Friday, the Better Business Bureau offered the following tips:1) Stay Safe. Follow CDC guidelines to healthy and safe while in the store.2) Make the most of Black Friday deals. Start with a list of items and use sale flyers and promotions to determine which store has the best price. Set a budget and stick with it before heading out.3) Read the fine printSome retailers may offer an additional percentage off the purchase, but could exclude certain deals or items such as “door busters.” Watch for companies boasting a high percentage off; the item may be “75% off,” but the original price could be inflated. Carefully check the price tags, terms, and conditions. Research online using a secure wifi connection to see if competitors have the item at a better price.4) Plan out the excursion. Sometimes it's not necessary to wait to see what deals will be offered on Black Friday. Retailers often will release Black Friday flyers weeks ahead of time, so consumers can plan out their shopping spree. Make a map of the stores to visit and what items are at which store. Some retailors only honor sale ads during a certain time frame, or on certain days, and could limit the amount of deeply discounted items available for purchase.5) Sign-up for email alerts. Many stores release their best Black Friday deals and exclusive coupons to people who have subscribed to their emails. Sign up ahead of the holiday season, and then unsubscribe afterwards if needed.6) Do your research. Read product reviews on extremely discounted items. It could be a cheaper model or brand advertised, and not what was expected. Check BBB.org for Business Profiles of the stores and read what other customers’ have experienced.7) Know the return policy and warranty information.Pass along any information about returns, exchanges, repairs, and warranties to the person who will use the item. Gift receipts are an easy way for recipients to return or exchange a gift if it’s not just right, but make sure the item is able to be returned before purchasing.Visit BBB.org to look up a business, file a complaint, write a customer review, report a scam, read tips, follow us on social media, and more! 2894
