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

ATLANTA — Georgia’s top elections official says his office is investigating potential election law violations by groups working to register voters ahead of January's Senate runoffs. Secretary of State Brad Raffensperger named four groups his office is specifically investigating: America Votes, Vote Forward, The New Georgia Project and Operation New Voter Registration Georgia. He says some groups are allegedly encouraging people outside the state to register to vote in January's Senate run-off election, according to The Hill. “We have opened an investigation into a group called America Votes, who is sending absentee ballot applications to people at addresses where they have not lived since 1994,” Raffensperger said Monday in announcing the investigations. America Votes responded to the accusations in a statement to the Atlanta Journal Constitution, saying they have mailed applications to those on the list of voters maintained by Raffensperger's office. The secretary is also punching back at claims that fraud has tainted the state’s presidential election. Raffensperger said dishonest actors are exploiting the emotions of many Trump supporters with fantastic claims and apparently misleading the president as well. He said during a news conference Monday that his office has 23 investigators probing 250 open cases alleging some kind of election law violation, but none of them cast doubt on the integrity of the state's election results. 1461

As schools discuss in-person versus online learning for fall, parents are weighing their options. Homeschool groups are seeing increased interest from parents across the U.S.“We are homeschooling,” said Karissa Yeager, a mother in California. “We have decided we're just going to pull them from public school for the year and home school.”Yeager is a mother of two, and she’s concerned about the possibility of putting her 7 and 4-year-old daughters through mandatory mask-wearing requirements, in addition to other rules that may come with in-person learning this fall.“Let's just keep them home and put them in social situations where they’re still going to get to be kids, instead of sending them to school. I just didn't want the new formation of school to be what they think about when thought about school,” she said.Yeager is not alone.“Parents in droves are investigating and committing to homeschooling for this upcoming school year,” Linda Maepa, a board member with the Homeschool Association of California, said.Maepa is no stranger to teaching her kids. “I'm a veteran homeschooling mom of three,” she said. “Homeschooling allows you to build a lifestyle around education, around a love of learning.”With many schools moving to an online model for at least the beginning of this school year, parents are looking into the differences between online and homeschooling.“It’s using everything at your fingertips, everything that's available to you, to use as a learning tool. Going to the grocery store, pulling cans of soup off the shelf and looking at the label, said J. Allen Weston, the executive director of the National Homeschool Association.“We've had problems for decades, maybe over a century now, of being able to keep kids confined to a desk for six to eight hours a day. Now, trying to pin them in front of a screen for that same six to eight hours a day is going to be a disaster."But online learning expert Leanna Archambault, an associate professor at Arizona State University, says online school doesn’t have to be that way.“It can be interactive. I think it's just limited to the creativity of the teacher and the families, but there is this misconception that it's just sitting in front of the computer all the time, which we know is not a healthy thing in any kind of setting,” Archambault said.She said homeschooling is more like an individual sport, where parents are curating and teaching their kids. “Versus the online learning where there's a curriculum developed by a team, the teacher is there as a facilitator, the parent is really there as a learning coach,” she explained. “Online learning would be more of a team sport.”Homeschoolers say that’s not always the case.“What we create is pods and that's groups of families that all work full-time,” Weston said. “They take turns hosting each other's kids.”“You will find your type of situation represented among all homeschoolers. So ask, join your local communities and ask,” Maepa suggested.Regardless of a parent’s decision, the school system has been disrupted, and Maepa says it’s impacting everyone. “Everybody is doing something very different than what they've been doing every day for their education for their families,” she said.Archambault says she sees this disruption changing the way education works in the future. “That we reevaluate this strategic blend of what works well online and what potentially works well face-to-face when we’re allowed to return, and moving forward I think there's going to be a blend,” Archambault said. 3541

As one of the world's most famous prehistoric monuments, Stonehenge still holds many secrets despite centuries of study. For the first time, new research is lifting the veil on the people who are buried at Stonehenge.The study was published in the journal Scientific Reports on Thursday.Much of the previous research around the monument in Wiltshire, England, has centered around how or why Stonehenge was built -- not the people buried there or who built it.But studying the human remains at Stonehenge is no easy task. In addition to dating back to 3,000 BC, the remains were also cremated. During the early phase of Stonehenge's history, it largely served as a cemetery.Fortunately, lead study author Christophe Snoeck, post-doctoral researcher at the Vrije Universiteit Brussel, combined his passions for archeology and chemical engineering to pioneer developments in archaeological analysis.The results revealed that 40% of the people buried at Stonehenge likely came from west Wales, the suggested origin of the site's smaller bluestones, and they most likely helped transport the stones and build Stonehenge. Signals from the bone analysis suggested that within the last ten years of their lives, these people were not living at Stonehenge nor originally from the area around Stonehenge, known as the Wessex region."Our results are the first one to provide direct evidence on the origin of those buried at Stonehenge, shedding light on the importance of the site in the Neolithic landscape," Snoeck said in an email. 1531
