As school districts across the country prepare to send kids back to school in-person, many bus drivers are voicing concerns about the potential for COVID-19 to spread on school buses, where oftentimes social distancing is nearly impossible.For the better part of 32 years, Cheryl Merritt has driven a school bus in Hanover, Massachusetts. She has driven in every kind of weather condition imaginable, but this is the first year she’ll be driving a bus during a pandemic.“I just want all the kids on the bus to stay safe and the drivers to stay safe. If we have a driver who gets sick, they’re going to be out for at least 14 days,” she lamented, as she turned her bus onto a side street in a residential New England town.Merritt’s concerns are shared by school bus drivers and districts across the country. Many school bus drivers have retired from other professions, meaning their age makes them more susceptible to catching the virus.“I don’t want this, I don’t. I’m not ready to die,” the 61-year-old Merritt said.School buses are presenting a particularly difficult challenge as districts try to send kids back to the classroom. When fully loaded with kids, most school buses fit about 77 students. Cramming students into a bus though would be a perfect place for COVID-19 to spread, so many states are advising bus companies to have only one student per bench. But taking some bus capacity down to about 12 kids means school districts would need to run double or triple the number of trips each day just to pick every child up.Transportation experts say adding more buses would be nearly impossible given a nationwide bus driver shortage, which existed long before the outbreak.“It doesn’t matter what you’re gonna do with kids once you get them to school, you have to get them there first,” explained David Strong, who works with the School Transportation Association of Massachusetts.Strong’s other concern is that kids won’t adhere to social distancing guidelines or mask-wearing requirements once they get onto a bus.“There’s almost no way to realistically social distance on a bus,” he added.To address concerns about the spread of COVID, many school districts are mandating that school buses keep their windows open year-round to help with the flow of air. Some districts are also adding bus monitors to ensure kids, especially elementary school students, are following new guidelines.As for Merritt, she sees herself and other bus drivers as the first line of defense when it comes to keeping COVID-19 out of the classroom.“When you stop to pick up a child look at them, make sure they don’t look sickly or they’re coughing,” she said. 2655

As we're all focused on the current rollout of the COVID-19 vaccine, a technology known as thin-film freezing is getting a lot of attention. It's groundbreaking and could change the way we administer drugs or use medicine in general.You've probably heard about the need to keep the COVID-19 vaccine cold. It has to be so cold, in fact, that the shipment and transport are challenging. Well, what if that vaccine could be turned into powder?“What we’ve most recently been working on is the elimination of cold chain by storing as a powder, a dry powder where the drug is much more stable than if it was stored as a liquid or as a frozen liquid,” said co-inventor Dr. Robert Williams.Williams said it would eliminate the need for extreme cold storage and transport. The technology isn't new. He got a research grant and came up with it about 15 years ago.Williams, who is also a pharmacy professor at the University of Texas in Austin, said they were working on the technology and its multiple uses when the pandemic hit. And all of a sudden, they got a lot of attention.“We have published over 70 papers on the technology and using it for different products- it’s quite a mature process," Williams said. "We developed it because with other vaccines, the majority of the vaccine cost is in wastage because of this cold chain issue, so we published several key papers where we showed our thin-film freezing technology would protect vaccines - and you wouldn’t need cold chain storage.”Glenn Mattes, President, and CEO of TFF Pharmaceuticals added that the powders can be converted to topical preparations and they are currently working with the US Army to take some of the preparations and would then administer them directly through the eye.TFF is launching thin-film freezing into development through the FDA process. “I use the term ubiquitous because it is and disruptive because it is,” Mattes said. He added that they've explored their technology in the cannabinoid realm. But, as for the COVID vaccine, they're aiming for a second-generation usage.“To truly eradicate the pandemic, you have to have a global response," Mattes said. "The companies we’ve been speaking to certainly recognize the broad utilization of the technology but the application to the developing world, rural area, remote areas, where you can take a powder and inhale it or take the powder and reconstitute it has tremendous potential."Experts say it is only just the beginning as they launch their technology into a new world. 2511

Attorneys representing the state of Missouri announced Monday they will drop a felony invasion of privacy charge against Gov. Eric Greitens, after the attorney prosecuting the case was named as a witness in the trial.However, the decision might only mark a temporary victory for Greitens. Prosecutors said they plan to name either a special prosecutor or one of St. Louis Circuit Attorney Kim Gardner's assistants to refile the charge and move forward with the case. 474

As the counting of ballots continue, one trend is emerging: the final result will be close. A potential consequence of that will be a recount. Perhaps in one state or in multiple states. RECOUNT RULESEach state handles recounts differently. For example, in Arizona, an automatic recount is triggered if the margin between candidates is less than or equal to 0.1 percent of the votes cast. In Georgia, candidates can request recounts if the margin is no more than .5 percent of total votes cast.DO RECOUNTS CHANGE ANYTHINGAccording to FairVote.org, recounts rarely change races. Since 1980, there have been 5,778 statewide elections.There have only been 31 completed statewide recounts.Only three have been overturned because of a recount.Perhaps the most famous recount of all was in Florida in 2000.But the 2000 Florida Recount only shifted the final margins by 1,247 votes or 0.02%In a recount in Wisconsin in the 2016 Presidential race, the final margin only changed by 571 votes. "I believe recounts in themselves are not in favor of those who have lost a race unless it's a very close margin," Dr. Eric Claville, a political scientist with Norfolk State University said. 1183

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
