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.

Protecting yourself from sickness has become a top priority for many people right now.Whether you're trying to steer clear of the novel coronavirus or germs in general, there are a few simple things families can do to keep their immunity in top form."First, it's important to remember that nothing you do is 100% guaranteed in preventing you from getting sick, but there are certain lifestyle changes you can make that can actually help your immune system react better when there are pathogenic invaders that would cause diseases," said SaVanna Shoemaker, a registered dietician with Healthline.Shoemaker and other experts overwhelmingly say getting enough sleep is number one."Making sure that you’re getting plenty of sleep,” said Shoemaker. Sleep and immunity are so deeply linked, so just getting adequate sleep can help you from getting sick as often.""When you have a disruptive sleep cycle and you're not getting good, adequate, restorative sleep, then our immune system takes a hit for that," said Joe Weydert, the Chair of Integrative Medicine at the American Academy of Pediatrics.She says younger children need nine to 11 hours of sleep, while teenagers could use eight to 10 hours.Also, watch out for stress. Consistent, high levels of stress can weaken your immune system."In these goofy times that we’re living in right now, we’re all experiencing high levels of stress. Kids may not say 'Oh mom, I’m stressed,' but they may manifest it by being more irritable or not sleeping well," said Weydert.Getting outside or prioritizing time to relax can help.Another major factor in keeping our immunity strong is our diet – eating rich, whole foods that are not processed. Probiotics can also help.As for supplements, "the thing you need to consider with supplements is there’s no guarantee. Now there are some supplements that some studies show may boost your immunity, but so far there’s no research in any supplement that shows it can prevent COVID-19," said Shoemaker.Vitamin D has a direct impact on our immune system, preferably straight from the sun. Elderberry is a supplement that's strongly recommended by many doctors for families, as it acts as a barrier to viruses."Other nutrients which I think are important are vitamin C and zinc. Those work together to help make what we call tight junctions in the epithelial cells. So, our epithelial cells need to be tight together so germs can't get through and vitamin C and zinc help maintain that tight junction with things," said Weydert.While supplements are certainly beneficial, experts advise getting the vitamins naturally through food. These tools are helpful in keeping your immune system at its best and a great addition to other safety measures like wearing a mask, washing your hands and social distancing as many do their best to avoid COVID-19. 2830

Presidential candidate Joe Biden spoke out on Wednesday on the shooting of Jacob Blake in Kenosha, Wisconsin. Blake was shot by police in Wisconsin on Sunday, causing unrest in Kenosha.Two officers from the incident have been placed on administrative leave. But protesters are calling for the officers to be fired and criminally charged for the shooting.Biden confirmed that he has talked to the Blake Family about the shooting.“What I saw on that video makes me sick,” Biden said. “Once again, a black man, Jacob Blake, been shot by the police in the broad daylight, the whole world watching”Biden said he told the Blake Family that “justice must and will be done.”While Biden applauded the protests, he decried the violence surrounding the protests. The violence culminated on Tuesday in the fatal shooting of two people. Police in Illinois arrested a 17-year-old in connection to the shootings.“As I said after George Floyd's murder, protesting brutality is a right and absolutely necessary, but burning down communities is not protest,” Biden said. “It's needless violence. Violence that endangers lives, violence that guts businesses and shutters businesses that serve the community. That's wrong. In the midst of this pain, the wisest words that I've heard spoken so far have come from Julia Jackson, Jacob's mother. She looked at the damage done in her community and she said this, quote ‘This doesn't reflect my son or my family. So let's unite, and heal, do justice, end the violence, and systemic racism in this country now.’Protests are expected to continue in Kenosha on Wednesday. President Donald Trump said that the state’s governor had accepted help from the National Guard, but the state’s governor, Democrat Tony Evers, said that he had not agreed to National Guard assistance, but would welcome federal assistance in a support role. 1859

Prosecutors rested their case Monday afternoon in the trial against former Trump campaign chairman Paul Manafort.This comes after 10 days of testimony from 27 witnesses. The defense has not indicated if it will call any witnesses to the stand.Prior to the prosecution resting, a bank official testified that the Federal Savings Bank gave Manafort million in loans and knew that he lied about his financial situation before they were approved by the bank's chairman.James Brennan, a vice president of Federal Savings Bank, said he faced so much pressure from his bank's chairman about Manafort's ability to borrow the million that he lied on a form reviewed by federal regulators and the bank's directors about the stability of the loan."If I had my recommendation ... the loan would not be made," Brennan said in court Monday.Brennan, who wrote a memorandum about a second .5 million loan the bank extended to Manafort, said he had given the loan a rating of "4." But in court Monday, he said he shouldn't have done that.A very stable, high-quality loan would get a rating of "1," and any rating less than "4" wouldn't get approved and would draw regulators' attention because of its instability, he said.When asked by prosecutors why the loan received a 4 rating, Brennan said it was because of "Mr. Calk," referring to the bank's founder, Stephen Calk."It closed because Mr. Calk wanted it to close," Brennan said, referring to one of the loans.Last week, the jury heard testimony that Calk approved the loans as he sought Manafort's help in getting a high-ranking position in the Trump administration.Brennan also said he and his colleagues documented their concerns about Manafort's personal finances. Information about Manafort's company's income, his unpaid debts from his Yankees season ticket and undisclosed mortgages on his other properties in New York raised red flags internally at the bank, he added.Brennan was the 27th prosecution witness to testify against Manafort in the first major test in court for special counsel Robert Mueller, who is currently leading an investigation into Russian interference in the 2016 election.Manafort has been charged with 18 tax and banking crimes. He has pleaded not guilty to all charges.Prosecutors pulled up an email that Brennan sent to colleagues who sat on the bank's loan-approving committee in September 2016. The email detailed some of "the issues we were having" regarding one of Manafort's loan applications, Brennan said.Brennan also described how he asked Stephen Calk's brother, John Calk, another major Federal Savings Bank shareholder, to sign off on the loans to Manafort, but John Calk refused.In all, the bank lost .8 million on the loans it made to Manafort, Brennan said. 2763
