President-elect Joe Biden named former General Lloyd J. Austin as his nominee for secretary of defense on Wednesday.If confirmed, Austin would become the first Black person to lead the Pentagon.At a press conference in Wilmington, Delaware on Wednesday, Biden introduced Austin as a man who is "breaking down barriers and blazing a trail," adding that he is "going to do it again" if confirmed.Biden called for Austin to be confirmed "swiftly," adding that the country "needs his expertise.""It will be my sincere honor and privilege to return to the department and to lead our great service members and civilians in accomplishing the mission of ensuring our nation's security," Austin said Wednesday.He also added that he would give Biden clear and "unvarnished council" when it comes to military matters.Austin also said that he had benefitted greatly from leadership above him throughout his career, citing the influence of former Sec. of State Colin Powell, among others.In addition to needing Senate confirmation, Austin will also need a waiver, as there is seven-year waiting period after leaving the military in order to become defense secretary. Some Senate Democrats, including Sen. Elizabeth Warren, have signaled that they are hesitant to grant Austin a waiver."I would not be asking for this exception if I didn't think this moment in history called for it," Biden said.President Donald Trump's first defense secretary, James Mattis, also required such a waiver upon his nomination.Austin, a former four-star general, was the 12th head of Central Command from 2013 through 2016 under President Barack Obama.Austin followed Mattis in leading Central Command. He also served as the vice chief of staff of the Army. 1732

President Donald Trump suggested during an interview on Wednesday that he will accept the presidential nomination of the Republican party in a live address from the White House later this month.During an interview on Fox News, Trump told anchors that his administration is still weighing its options, but that he's currently leaning toward an option that would have him deliver the speech "live from the White House lawn," calling it the "easiest and least expensive option."Trump also suggested Wednesday that the press would be allowed to attend parts of the convention that will be taking place in Charlotte. Last week, reports emerged that indicated that the administration was considering barring the press from the nomination vote.The Republican National Convention, currently slated to take place between Aug. 24 and Aug. 27, has been completely upended due to the COVID-19 pandemic.The convention was originally slated to take place in Charlotte, North Carolina. However, Trump announced earlier this year that he would move portions of the convention to Jacksonville, Florida because he felt North Carolina Gov. Roy Cooper, a Democrat, was too slow to lift COVID-19 related lockdown restrictions.After cases began spiking at record levels in July, Trump mostly canceled the Jacksonville portion of the event."I looked at my team and I said the timing for this event is not right. It's just not right with what's been happening," Trump said on July 23. 1468

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.

QUITO, Ecuador (AP) — Julio Mora slipped away from his parents to secretly marry Waldramina Quinteros one February day. Both families disapproved. But seventy-nine years later, they’re still together — he at 110 years of age, and she at 104. Both are lucid and in good health, though relatives say they’re a little depressed because they miss their big family get-togethers due to the pandemic. And they can gather quite a crowd: four surviving children, 11 grandchildren, 21 great-grandchildren and one great-great-grandchild.There are longer marriages, but at the moment none between people so old — just short of a combined 215 years. It's a mark now certified by Guinness World Records. The couple received a certification earlier this month. Previously listed as the oldest were an Austin, Texas, couple, Charlotte Henderson and John Henderson who have a combined age of 212 years and 52 days. 906
