ATLANTA, Ga. – The head of the Centers for Disease Control and Prevention says the United States could get the coronavirus pandemic under control in one to two months if all Americans wear face coverings in public spaces.CDC Director Dr. Robert Redfield made the statement during an interview with the Journal of the American Medical Association, or JAMA, on Tuesday.“I think the data is clearly there that masking works,” Redfield told JAMA. “I think that if we can get everybody to wear a mask right now, I really do think that over the next four, six, eight weeks, we can bring this epidemic under control.”Redfield’s comments coincided with the release of two case studies that show how wearing face coverings can significantly reduce the transmission of the coronavirus.One of the studies, from JAMA, showed that a Boston hospital system reversed the infection trajectory among its employees and patients by adhering to universal masking policies.In the second study, the CDC highlighted how wearing a mask prevented the spread of infection from two hair stylists to their customers in Missouri.“Among 139 clients exposed to two symptomatic hair stylists with confirmed COVID-19 while both the stylists and the clients wore face masks, no symptomatic secondary cases were reported; among 67 clients tested for SARS-CoV-2, all test results were negative,” wrote the CDC. “Adherence to the community’s and company’s face-covering policy likely mitigated spread of SARS-CoV-2.”Experts say the virus that causes COVID-19 is thought to mainly spread from person to person, mainly through respiratory droplets produced when an infected person coughs, sneezes or talks.“These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs,” writes the CDC. “Spread is more likely when people are in close contact with one another (within about 6 feet).”In an editorial published by JAMA, the CDC affirmed that cloth face coverings are a critical tool to help stop this kind of spread.“We are not defenseless against COVID-19,” said Redfield. “Cloth face coverings are one of the most powerful weapons we have to slow and stop the spread of the virus – particularly when used universally within a community setting. All Americans have a responsibility to protect themselves, their families, and their communities.”The U.S. continues to lead the world in the number of COVID-19 cases, with nearly 3.5 million infections reported as of Thursday morning, according to a tally by Johns Hopkins University.Click here to learn more about COVID-19 from the CDC. 2600

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

ATLANTA, Ga. (AP) — U.S. Attorney General Bill Barr says the federal government is awarding more than 0 million in grants to target human trafficking.The money will go to task forces combatting human trafficking, to victim services and victim housing.Barr made the announcement Monday in Atlanta with presidential adviser Ivanka Trump, Georgia Gov. Brian Kemp and athlete Tim Tebow, whose foundation is focused on combating human trafficking.Tebow was among those who spoke at the event, saying that we have to live with a sense of urgency to be able to rescue as many lives as possible.“It’s a calling because we believe it’s the greatest form of evil in the world today, because there are 40 million people around the world that need us,” said Tebow during the event. “They need us to say, no longer is it about the credit, it’s about the mission.”Tebow also posted about attending the event on his social media.Please join us in prayer as we continue our work to #EndHumanTrafficking pic.twitter.com/oyxilf0Uq3— Tim Tebow (@TimTebow) September 21, 2020 President Donald Trump’s administration in August awarded million in Justice Department grants to organizations that provide safe housing for victims of human trafficking.The announcement came after Barr, Trump and the Kemps toured the Georgia Center for Child Advocacy southwest of downtown Atlanta. 1371

As pressure mounts for congressional action on gun control, it's unclear just how much can be done given the thick political fog that shrouds any major legislative effort on Capitol Hill -- especially in an election year.President Donald Trump tweeted Thursday that Congress "is in a mood to finally do something on this issue," but lawmakers are at home on a weeklong recess and it's too soon to tell if there's enough appetite to tackle gun legislation when they return next week. Republican leadership in the House and Senate have been silent on the question.A number of proposals to curb gun violence are floating around in Congress, some of which were started last year after a spate of other mass shootings.  727

As new wildfires force tens of thousands of people out of their homes, reports are emerging of flaws in emergency alert systems throughout the west."Where I think the false sense of security was, if something really bad is going to happen, we'll get alerted well beforehand," said Vacaville resident, Will Carlson.Carlson and several of his neighbors say they received no warnings as the Hennessey Fire inched closer to their homes. At around midnight, Carlson saw the flames moving quickly down a hill in the distance. Carlson was one of the last to leave, working frantically to help save animals on the property."What I remember is this sinking feeling in my stomach, and this helplessness that this barn is going to go up in flames, and the horses will be burned alive," said Carlson.After making it out safely, Carlson was left wondering how this could have happened. "Every neighbor that we talked to it was the same story, we knew there was a fire in the area, we thought that we would get alerted, and nothing was said to us," said Carlson. Le'Ron Cummings, public information officer for the Solano County Sheriff's Office, says alerts went out to these areas. However, they cannot guarantee the targeted population will get the message if cell service, internet, or landline signals are impacted. He says it was determined that cellular services and power were affected by the fire.Solano County uses the Everbridge platform to alert residents via the AlertSolano program, delivering Amber Alert-style messages. Cummings says during an evacuation, the Solano County Sheriff's Office and allied law agencies do door-to-door notifications in addition to AlertSolano messaging. The Sheriff's office also uses the High-Low Siren system familiar in Europe to advise residents to evacuate immediately.Carlson says he is frustrated with the response because he believes he had full cellular service throughout the night, texting and posting to social media as he evacuated. "So I think that's where the frustration came in from that night. How many animals could have been saved? Could there have been less loss of life? And could structures have been defended better if we had more warning?" said Carlson. Carlson says two people in his neighborhood died in the fire; however, county officials say they have no reason to believe the alert system was associated with fire-related deaths.Napa County also experienced some kinks with its alert system, when a coding error prevented an alert from going out. Emergency officials say it was an error on the part of its vendor and that the message was not urgent. Staff realized the problem, and they were able to use a different platform to send out the alert. "It happens over and over again," said Art Botterell, who is now retired from the State of California's Office of Emergency Services.Botterell led the effort to develop the Common Alerting Protocol, which he says led to the creation of the FEMA Integrated Public Warning System and some products from the National Weather Service."We've got a pretty good penetration of cellphones, sirens, and telephone dialer systems, that's not usually what breaks down. What usually breaks down is that alert is not sent in time or not sent at all," said Botterell. He says during a 2017 wildfire in Sonoma County, that would prove deadly and destructive, officials failed to send an alert, fearing it would cause panic and clog roadways. Botterell says another reason alerts are often not sent is because officials believe they don't have enough information."It is fair to say that in a lot of cases, we have not given our public safety people the tools to issue public safety warnings effectively," said Botterell. Botterell says more training is needed and believes state and federal governments should provide more guidance to ensure effective responses.With the vulnerabilities in cellular towers and alert systems as a whole, Botterell says counties must utilize several tools to try and reach everyone."We've got a lot of technology. Now we need to get good at using it." 4083
