Researchers from Florida Atlantic University released a video on Tuesday that shows how droplets disperse into the air from a person’s mouth.The researchers used different kinds of masks to analyze the disbursement of the droplets. The researchers also showed that without a mask, six feet of distance might not be enough to avoid infection.The FAU team tested a single-layer bandana-style covering, a homemade mask that was stitched using two-layers of cotton quilting fabric consisting of 70 threads per inch, and a non-sterile cone-style mask that is available in most pharmacies. The team used a mannequin, Laser lights and synthetic fog to help visualize the spread of the droplet from a cough..The researchers said that stitched quilted cotton masks worked the best in the simulation, with droplets from emulated coughs traveling just 2.5 inches from the mask. By comparison, without a mask, the droplets moved more than 8 feet, with some droplets traveling up to 12 feet during a heavy cough. The researchers also noted that the droplets remained suspended in midair for up to three minutes in the simulated environment.“We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point,” said Dhanak. “Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing.”FAU said that droplets from a cough traveled 3 feet, 7 inches from a bandana; 1 foot, 3 inches from a folded handkerchief; and 8 inches from a cone-style mask.“Preliminary results from our experiment reveal that significant concentrations of small particles from a turbulent jet such as from a heavy cough/sneeze can linger in still air for more than one minute. It only took the particles a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet,” said Siddhartha Verma, an assistant professor in FAU’s Department of Ocean and Mechanical Engineering.Last week, the University of Washington’s Institute for Health Metrics and Evaluation projected that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.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.The CDC issued guidance in April to recommend mask wearing while in public, which has become a requirement to enter retail establishments in more than a dozen states.The CDC's guidance stressed several points: That wearing a face covering is not a substitute for social distancing, and that the public should not use medical or surgical masks. The recommendations suggest the public should use fabric or cloth that covers the mouth and nose.To view FAU's video, click here. Justin Boggs is a writer for the E.W. Scripps National Desk.

President Donald Trump's legal team is preparing to respond to special counsel Robert Mueller regarding the possibility of an interview, Rudy Giuliani told CNN Monday.Giuliani, one of Trump's lawyers, would not characterize the response. He's recently suggested that Trump and his lawyers would be making a final decision soon, but other sources have said the coming response would likely be another effort to counter the latest from Mueller and not a final offer.CNN reported last week that Mueller has offered to reduce the number of obstruction-related questions Trump would be asked by investigators. The President's lawyers had previously offered the special counsel written answers to obstruction questions and limiting the interview to matters before his presidential inauguration, which are largely confined to collusion.The special counsel indicated an interview with the President would include obstruction questions, but did cede that some answers on topics could be in writing. Trump's lawyers -- who are not in favor of any interview despite the President saying he wants to set the record straight with special counsel -- are seeking to limit the interview to collusion topics.The-CNN-Wire 1211

Ray Szmanda, known to generations of Americans as the man who brought Menards commercials to life, has died at age 91.Szmanda passed away at his home in Antigo on Sunday, May 6, according to an obituary posted to Bradley Funeral Home & Crematory's website.Szmanda worked in T.V. and radio in the 1950s and operated a broadcast school in Waukesha, Wisconsin until the late 1970s, when he joined Menards as a pitchman. After a successful run, Szmanda retired as the spokesman in 1998.Menards released a statement about the loss of their beloved spokesman:"Ray Szmanda remained a steady fixture in our advertising for nearly a quarter century  until his retirement in 1998.  Still to this day, Ray’s friendly, enthusiastic and fun loving personality have made a lasting impression on our customers and all of us at Menards. We are saddened by his passing and our thoughts and prayers are with Ray’s family, friends and the millions of people who knew him as ‘The Menards Guy.'"His countless commercial appearances over the decades, as well as his distinctive voice, endeared Szmanda to many across the years."I'm having a ball; I love what I do, and I think as long as I feel that way, that message gets across on television," Szmanda once said, according to his official biography on the Menards website.Szmanda graduated from Milwaukee's Bay View High School in 1944. In 1970 he founded the Transamerica School of Broadcasting in Wausau, helping local talent to achieve their dreams, and preparing them for the airwaves. Szmanda also performed as a drummer and vocalist in Wisconsin clubs.Additionally, Szmanda served his country in the Navy in WWII. 1707

RANCHO SANTA FE (KGTV): As the costs to grow avocado and citrus keep rising, farmers in San Diego are trying a new crop to put a jolt in their business: coffee."We’re excited about the possibilities," says Chuck Badger, who runs R.E. Badger and Sons. He's planted about 5,000 coffee plants across several farms that his business manages."The plants are very happy. They’ve got a lot of cherries on them. So we’re super excited for this summer to pick it."Badger says he heard about the possibilities of coffee from growers in Ventura County. San Diego's coastal climate and soil are similar to other coffee producing regions.The timing couldn't be better. In addition to dealing with the lingering drought, many farmers are getting frustrated with the rising production costs of avocado and citrus trees. They're looking for ways to diversify their crops.Badger says the upfront costs of coffee are a little higher, but the profit margins can be much better. He told 10News that coffee needs about 900 trees planted per acre, while citrus uses only 150.But, if the coffee grades out as a "premium" brand, farmers could net as much as ,000 per acre. Citrus and avocado trees bring in anywhere from ,000 to ,000 an acre, depending on the yield and other market factors.Leaders with the San Diego County Farm Bureau are excited about the potential as well, but caution that coffee is still in an "experimental" phase in the area."Nobody's all in at this point," says Executive Director Eric Larson. He points out that San Diego has around 50,000 acres of total farmland. Larson guesses that coffee makes up less than 20 total acres right now."Folks are seeing if it’s going to work here before they make a future decision to be all in," says LarsonHe says it could be a good crop to plant in conjunction with other established crops, doubling up acreage to increase profits.Badger thinks San Diego could become coffee country, in the same way Napa is known for wine."We want to model it after the whole wine growing template, where people are asking for certain varietals, certain regions, organic," he says. "So those coffee snobs become like those wine snobs and will pay for premium coffee."Badger won't be able to harvest any of his beans until next summer. He's looking forward to seeing how it all plays out."If you look at what the world wants and what people are spending money on, I think it will be a good thing." 2447

Relatives of Richard Russell say they are "stunned and heartbroken" after the airline worker stole a passenger plane Friday from the Seattle-Tacoma International Airport and was killed when he crashed 25 miles away."This is a complete shock to us," the family said in a statement Saturday night. "We are devastated by these events, and Jesus is truly the only one holding this family together right now."The statement said Russell, 29, was "a faithful husband, a loving son and a good friend."Referring to audio recordings of Russell talking to air traffic control during his hour-long flight, the statement said his "intent was not to harm anyone. He was right in saying that there are so many people who have loved him."Russell, a Horizon Air ground service agent for three and a half years, was the only person aboard the plane, the Pierce County Sheriff's Department said. The job of a ground service agent includes directing aircraft for takeoff and gate approach, handling baggage and tidying and de-icing planes, authorities said.The incident, which the FBI's Seattle office did not consider terrorism, raises questions about airport security. Investigators headed Saturday to the crash site to recover the plane's data recorders and Russell's remains as part of a criminal probe, authorities said. 1313
