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.

Rabbits are multiplying in the childrens' book section.Comedian John Oliver is provoking Mike Pence with a parody book about the vice president's pet bunny to coincide with the Pence family's release of a new children's book."Marlon Bundo's A Day in the Life of the Vice President" was written by the vice president's daughter, Charlotte Pence, and illustrated by second lady Karen Pence, a watercolor artist. The book, which is out Monday, "gives young readers a bunny's-eye view of the special duties of the vice president," per its publisher.Not to be out-bunned, HBO's "Last Week Tonight" released its own version, "Last Week Tonight with John Oliver Presents a Day in the Life of Marlon Bundo."The late-night comedy news program's book "tells the story of Vice President Mike Pence's famed pet rabbit's same-sex wedding," per its publisher."I live with my Mom, Grandma, and Grampa in an old, stuffy house on the grounds of the U.S. Naval Observatory. That's because my Grampa is the vice president. His name is Mike Pence. But this story isn't going to be about him because he isn't very fun. This story is about me, because I'm very, very fun," an excerpt of the spoof Bundo book reads alongside a watercolor picture of the rabbit, clad in a multicolor bow tie, hula-hooping on the grounds of the vice president's residence.Pence was criticized during his time as Indiana governor for his positions on issues important to the LGBTQ community, including signing a religious freedom bill into law in 2015.A spokesperson for Regnery Publishing, which issued the Pences' book, called the parody "unfortunate.""It's unfortunate that anyone would feel the need to ridicule an educational children's book and turn it into something controversial and partisan. Our and Mrs. and Charlotte Pence's goal is -- and will continue to be -- to educate young readers about the important role of the vice president, as well as to highlight the charities to which portions of the book proceeds will be donated," the spokesperson said in a statement.The proceeds of "A Day in the Life of Marlon Bundo" will be donated to The Trevor Project and AIDS United, while the Pences will donate a portion their proceeds to A21, a nonprofit focused on combating human trafficking, and an art therapy program at Riley Hospital for Children.The parody version of the book was the No.1 bestseller on?Amazon.com Monday morning. The Pence version ranked 15th. 2464

President Donald Trump will announce his decision on who to nominate to the Supreme Court on Saturday, and CNN and the New York Times reported Friday per their sources that Trump intends to nominate Judge Amy Coney Barrett to the court.Trump's formal announcement comes at 5 p.m. ET on Saturday.Barrett’s likely nomination will come just eight days following the death of liberal Justice Ruth Bader Ginsburg, who laid in state in the US Capitol on Friday.Barrett, 48, was previously confirmed by the US Senate to the federal Seventh Circuit Court of Appeals in 2017. Her vote garnered the support of three Democrats, Joe Donnelly, Tim Kaine, and Joe Manchin.She is a disciple of Justice Antonin Scalia, serving as his clerk in 1998 and 1999. Given her conservative bona fides, she is expected to give the Supreme Court a clear conservative advantage, fueling hopes from the evangelical right to overturn Roe versus Wade, which has set the precedent for abortion cases for nearly five decades. Liberals say Barrett’s legal views are too heavily influenced by her religious beliefs and fear her ascent to the nation’s highest court could lead to a scaling back of hard-fought abortion rights. She also would replace the justice who is best-known for fighting for women’s rights and equality.Sen. Dianne Feinstein told Barrett her views suggested religious tenets could guide her thinking on the law, the California Democrat telling Barrett: “The conclusion one draws is that the dogma lives loudly within you.”Barrett responded that her views had evolved and that she agreed judges shouldn’t “follow their personal convictions in the decision of a case, rather than what the law requires.”While two Republican senators, Susan Collins of Maine and Lisa Murkowski of Alaska, have said that a confirmation should not come so close to an election, enough Republican senators have said they would be supportive of Trump’s nominee to ensure a confirmation.Trump will likely become the first president to fill three Supreme Court vacancies in a single term since President Richard Nixon’s first term from 1969 through 1973.At just 48, Barrett would be the youngest justice and her tenure could last for decades. She’s made her mark in law primarily as an academic at the University of Notre Dame, where she began teaching at age 30. She first donned judges’ robes in 2017 after Trump nominated her to the 7th Circuit.The Associated Press contributed to this report. 2464
