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 thanked multiple members of Congress involved in passing the John S. McCain National Defense Authorization Act at a signing ceremony at Fort Drum, New York, Monday, with one major exception: the senator for whom the bill is named."We would not be here for today's signing ceremony without the dedicated efforts without the dedicated members of Congress who worked so hard to pass the National Defense Authorization Act," Trump said, namechecking Republican members of Congress including Rep. Elise Stefanik, who spoke briefly and represents the district containing Fort Drum, as well as Don Baker, Dan Donovan, Joe Wilson and Martha McSally.Trump, who did not serve in the military himself, has previously attacked?McCain's record of service, saying the Vietnam veteran and former prisoner of war is "not a war hero" because he was captured."He is not a war hero," Trump told pollster Frank Luntz, who was hosting a July 2015 question-and-answer session at the Family Leadership Summit in Ames, Iowa."He is a war hero," Luntz interjected."He is a war hero because he was captured?" Trump said, cutting him off. "I like people that weren't captured, OK? I hate to tell you. He is a war hero because he was captured. OK, you can have -- I believe perhaps he is a war hero."Trump has since acknowledged that McCain is a hero, but?refused to apologize in subsequent interviews.McCain has been one of the administration's most outspoken Republican critics.The President hasn't backed down on his attacks on McCain, who was diagnosed with glioblastoma, a rare brain cancer, over a year ago. Trump has referenced McCain several times on the campaign trail over the past months without directly naming him, hitting the Arizona senator for his health care vote.Just hours after the signing ceremony, Trump continued the criticism at a campaign event for Rep. Claudia Tenney in Utica, New York."One of our wonderful senators said 'thumbs down' at two o'clock in the morning," he said.Although Trump claimed the Senate was one vote away, in reality, the vote was only to go to conference with the House on the Senate's "skinny repeal."McCain's daughter, conservative commentator Meghan McCain, called Trump's comments "gross and pathetic."John McCain, who is the Senate Armed Services Committee chairman, spearheaded efforts to pass the defense spending bill in the Senate."I am particularly humbled that my colleagues chose to designate legislation of such importance in my name. Serving on the Senate Armed Services Committee has been an incredibly meaningful experience since my first days on Capitol Hill," McCain said in a press release when the bill was passed earlier this month.The bill's formal name is the "John S. McCain National Defense Authorization Act for Fiscal Year 2019," and it is listed on the White House daily guidance as such, but Trump simply called it the "National Defense Authorization Act" at Fort Drum.In mostly scripted remarks Monday, Trump called the measure "the most significant investment in our military in our war fighters in modern history," saying he was "very proud to be a big, big part of it."He also touted the 6 billion in forthcoming 2019 fiscal year military funding, his administration's economic success, and the United States' "leadership in space." 3346

President Trump confirmed to reported in the White House Tuesday that he had called Russian President Vladimir Putin to congratulate him on his re-election."I had a call with President Putin and congratulated him on the victory, his electoral victory," Trump said. "The call had to do, also, with the fact that we will probably get together in the not too distant future so that we can ... discuss the arms race."Trump also made comments discussing increased military spending, and said he would also discuss issues relating to Ukraine and North Korea if he were to meet with Putin.Putin was re-elected as Russia's president Sunday, an election he won with 76 percent of the vote — an election that watchdogs said was far from fair but cleaner than in years past.Watch Trump's full comments in the video below. 823
President Donald Trump's former lawyer, Michael Cohen, is under federal investigation for tax fraud and possibly misrepresenting his finances, people familiar with the investigation told The Wall Street Journal.The reported investigation adds to the wide-ranging federal investigation Cohen is already facing in relation to his business affairs and work with Trump. According to the Journal, authorities are investigating whether Cohen underreported his income in federal tax returns, in which he reaped hundreds of thousands of dollars over the last five years.People familiar with the matter told the Journal that authorities are also investigating whether any bank employees were improperly permitted to offer Cohen loans when he didn't provide adequate documentation. Investigators are reportedly examining Cohen's relationship with Sterling National Bank, which financed Cohen's taxi medallion business, and looking closely at whether Cohen lied or misrepresented information on loan applications.Investigators are also looking into whether Cohen inflated his income "in loan applications and refinancing efforts," people familiar with the matter told the Journal.Cohen's former accountant, Jeffrey Getzel, has been subpoenaed as part of the investigation, the paper reports.Cohen has not been charged with a crime and the Journal said he previously denied wrongdoing. Lanny Davis, Cohen's attorney, declined to comment to the paper "out of respect for the ongoing investigation."CNN has not independently confirmed the Journal's report.Cohen is facing a wide-ranging federal investigation into his finances -- including potential bank fraud, campaign finance violations, and hush payments to women saying they had affairs with Trump, which the President has denied. Authorities raided Cohen's home, office and hotel room in April as part of the investigation.The former Trump "fixer" once said he would take a bullet for his boss, but in recent months, he's suggested that he's willing to cooperate with federal authorities.The-CNN-Wire 2050
