Gyms are doing whatever they can to get you back, but many are wondering if it’s safe. A public health expert says it depends on what precautions your gym is taking.“The fact is that the gyms don't spread disease,” said Dr. Jay Wolfson, a public health professor at the University of South Florida. “The people within them who are coming into the gym and not cleaning up after themselves and are not maintaining social distances, and the gym staff, if they're not being attentive and conscientious in terms of disinfecting, are the ones who are aiding a abetting the spread of the disease.”There's evidence showing coronavirus can be spread through aerosol and droplets. Those droplets can float in the air long enough to be inhaled. And they could travel more aggressively when we’re working out.“Just as when you yell and scream, and you'll be sweating, and you'll be hyperventilating sometimes, so those droplet nuclei are going to come out, which means the larger particles are going to rest on some of the equipment as well as in the air,” said Wolfson.Wolfson says it may be hard to monitor gyms across the country because the rules in certain cities and states are different. And it's hard to know if a case is tied to a gym.A Norwegian university looked at whether workout facilities played a role in the spread. It didn't find any cases in people who went to the gym and took proper precautions.Researchers said going to the gym is relatively safe in areas where there aren't many infections. 1509

Hope Hicks, who was named interim White House communications director in August, will now hold the job on a permanent basis, a White House spokesperson told CNN Tuesday.Hicks, a longtime aide to President Donald Trump who was one of the first staffers to join Trump's 2016 campaign, became the interim communications director after Anthony Scaramucci, the colorful and controversial Trump aide, was ousted from the job in July.Bloomberg earlier reported the development. 478

Goldman Sachs' chief economist says if masks were required across the country, it could save the U.S. economy from a 5% loss.According to Forbes and CNBC, Jan Hatzius said in a note to clients that a nationwide mask requirement would prevent the spread of COVID-19 and prevent the need for further lockdown restrictions."We find that face masks are associated with significantly better coronavirus outcomes," Hatzius said. "Our baseline estimate is that a national mandate could raise the percentage of people who wear masks by 15 [percentage points] and cut the daily growth rate of confirmed cases by 1.0 [percentage point] to 0.6%. These calculations imply that a face mask mandate could potentially substitute for lockdowns that would otherwise subtract nearly 5% from GDP."According to the Bureau of Economic Analysis, the U.S. GDP totaled about .54 trillion in the First Quarter of 2020. According to Hatzius' analysis, not instituting a national mask requirement would cost the U.S. economy just over trillion.Several studies show that a mask or facial covering limits the wearer from spreading airborne droplets when speaking, sneezing or coughing. The coronavirus can live outside the body in these droplets for several hours and, in turn, infect other people — even before the person who spread the droplets has exhibited symptoms of COVID-19.Earlier this year, the Centers for Disease Control and Prevention (CDC) issued guidance that strongly recommended all Americans over the age of 2 wear masks in public, particularly in situations that would make social distancing impossible. However, it's stopped short of requiring masks.The CDC also says those who have trouble breathing should not wear a mask if it puts the wearers' health at risk.President Donald Trump has left individual states to issue mask requirements as they see fit, but has notably chafed at wearing face coverings during public appearances. He has also declined to require masks at his indoor rallies.About one-third of states across the country currently require masks when in public. Forty-six states require masks in certain instances. Presumptive Democratic Presidential Nominee Joe Biden has said he would make masks a requirement for the remainder of the pandemic should he be elected president. 2298

HANCOCK COUNTY, Ind. — One family in Indianapolis got a present a little early this holiday season.U.S. Navy Lt. Tawnee Hinton has been in Djibouti, Africa with the Combined Joint Task Force working on counterterrorism operations for the last 14 months.While she was deployed, her four children, Amelia, 5; Leyton, 9; Avarie, 13, and Christian, 21, were only able to talk their mother over FaceTime or texting.“Though the Navy has taken me away from my family on several occasions, and my husband was deployed numerous times before his retirement, this was a particularly lengthy deployment,” Hinton said.One event Hinton didn’t miss this year was her daughter Avarie’s choir concert. Unknown to her children, Hinton was able to come home early and surprise them. 796

Grab your headphones and prepare to be blown away.NASA just announced it has heard the first-ever "sounds" of wind on Mars. But if you're expecting howling, swooshes and crackles, you're in for a surprise. These are vibrations, captured by NASA's InSight lander, which touched down on the Red Planet just last week. The craft will stay put until November 24, 2020, measuring quakes that happen anywhere on Mars.This week, the craft recorded something unexpected."InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 25 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast," the agency said.An air pressure sensor and a seismometer recorded the noise through the vibrations in the air and vibrations around the aircraft "caused by the wind moving over the spacecraft's solar panels."This is the only time when vibrations from the lander will be recorded by the seismometer, since it will be moved by the craft's robotic armed and placed on the Martian surface, along with other instruments.The craft's landing comes as part of NASA's mission to explore the planet's deep interior.InSight lander's sensors are designed to detect quakes and air pressure through wind vibrations. The lander will measure whether tremors have the same effect as earthquakes. The Seismic Experiment for Interior Structure (SEIS), the seismometer, will use the vibrations to help scientists configure more about the planet's interior."Capturing this audio was an unplanned treat. But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves," Bruce Banerdt, the InSight principal investigator at NASA's Jet Propulsion Laboratory, said in a statement.To better hear this bass sound, it's better you bring out your headphones, or your subwoofer, as NASA suggested.You can hear the sounds here and listen to NASA's news telecon with a panel of scientists here.The-CNN-Wire 2011
