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.

Queen Elizabeth II is reportedly down to just one dog after the passing of her dorgi, Vulcan, NBC News and People reported.According to NBC's TODAY, the dorgi is a crossbreed corgi and a dachshund.

Researchers at University of Michigan have developed a fake news detector to help fight against misinformation. The technology is "an algorithm-based system that identifies telltale linguistic cues in fake news stories." The team says the system is "comparable to and sometimes better than humans at correctly identifying fake news stories."According to their study, linguistic analysis tracks things like grammatical structure, word choice, punctuation and complexity. But there are challenges to making sure the system properly deciphers stories. Researchers say the difficulty in building a fake news detectors is not in developing the algorithm itself, "but in finding the right data with which to train that algorithm."The system is still in its beta stage. Details of the fake news detector system will be presented on August 24 at the International Conference on Computational Linguistics in Santa Fe. Read the full study here. 962

Republican Darrell Issa has represented the 49th Congressional District for nearly 20 years, but new signs are pointing to a Democrat taking that House seat in the November election.Republican Diane Harkey is vying for the position against Democrat Mike Levin.
