As the COVID-19 pandemic progresses, researchers say it is important to track how the coronavirus mutates because it could affect the efficacy of a vaccine.Like all living cells, viruses evolve their chemical make-up changes. In viruses like the flu, that happens frequently, which is why every year there is a new vaccine to treat whatever strain is expected to circulate. With COVID-19, however, those mutations happen much slower, according to research out of Arizona State University.“One of the things we’re still keeping an eye on is the evolution of this virus because that virus is still around in the community,” said Dr. Efrem Lim, an assistant professor at ASU. “Everyone is coming in blind to this. This is a novel virus. This isn’t something we have seen before.”In March, Arizona State University played host to our country’s fourth COVID-19 case. As soon as it was detected, Dr. Lim started studying how the virus mutates and sent his findings to the World Health Organization. It's something that still continues to this day.“This virus, overall, mutates pretty slowly, which is a good thing,” said Dr. Lim. “However, we can have instances where the virus can have very large, dramatic, mutations, such as deletions in the genome.”While rare, Dr. Lim says those mutations can be significant as it changes how the virus acts inside the body.Currently, scientists are focusing much of their efforts on identifying ways to eliminate the function of the spike protein in COVID-19, as it is the way the virus binds to our cells and infects them (spike proteins are the stalks that protrude from the center of the virus that make it so recognizable).“It is very good news that the virus is not changing rapidly,” said ASU virologist Dr. Brenda Hogue. “We will have to see over time, as the virus continues to circulate, as we put a vaccine into play, whether or not there will be any issues.”Dr. Lim says right now there does not appear to be any issues because the virus mutates slowly, but he adds it could adapt to a vaccine once one begins to circulate.He says more testing needs to be done to determine that, however. 2140

As Supreme Court nominee Brett Kavanaugh awaits a final Senate confirmation vote, a lawyer representing Christine Blasey Ford says she absolutely does not want him impeached if Democrats take control of Congress.Ford's attorney Debra Katz tells CNN's Dana Bash in an interview that Ford only wanted to tell her story to Senate Judiciary Committee members. She doesn't want the process to drag on into the next Congress should Democrats end up winning control on Capitol Hill."Professor Ford has not asked for anything of the sort. What she did was to come forward and testify before the Senate Judiciary Committee and agree to cooperate with any investigation by the FBI and that's what she sought to do here," Katz said.Ford accused Kavanaugh of sexually assaulting her at a party more than three decades ago while they were both in high school. Kavanaugh has repeatedly denied the allegation. The allegation threw his confirmation process into a tailspin for weeks, but it appears back on track now after a 51-49 vote to move past a key procedural step and three key senators saying they'll vote "yes" in the final confirmation vote Saturday. 1152

ATLANTA, Ga. -- From the motivational speeches of Dr. Martin Luther King Jr. to the spiritual guidance of Mahatma Gandhi, Morehouse College in Atlanta is literally covered with inspirational messages.One phrase, however, has become the mantra for what it takes to become a Morehouse man:“Iron sharpens iron,” said Morehouse College president Dr. David Thomas.Thomas says students and staff at this historically black men’s college have turned struggles into strengths for more than a century.“What we do here is something that doesn’t happen anywhere else on the planet,” he said.The Morehouse campus is quiet this summer with all classes now being taught online. A decision Thomas says may spill over into the fall semester.“I’ve got to do the best job I can for this college,”said Thomas. With staff and salary cuts already happening, the impacts of COVID-19 could last much longer.“When you talk to our students about their experience being here, they will often talk about the power of being in a place where black male excellence is an expectation,” Thomas said. “And that’s hard to communicate in a virtual experience."Morehouse’s 2020 valedictorian, however, was able to express the difficultly of this new reality in simple terms“I think my experience when COVID hit was, I describe it as a little disappointing,” said new graduate Golden Daka.Though Daka is disappointed, he says his class has turned this pandemic into a learning experience.“It let us know that life isn’t not guaranteed and the most precious moments that you cherish could easily be taken away from you,” he said. “So, a lot of people are approaching this as a form of adversity to get stronger an to get better in areas of weakness.”In addition to closing campus, Morehouse College has also canceled all fall sports, which they say is the first Division II HBCU in the country to make that decision.“It’s heartbreaking for me,” Thomas said.Despite the disappointment, Thomas says Morehouse is more focused on academics than athletics, adding that the key to reopening campus is finding a vaccine.“We’re going to have to do that before I think we can declare victory against the virus,” he said.Morehouse now has the chance to play a role in that victory. Its school of medicine was awarded a million government initiative to combat COVID-19 in minority communities, something Thomas believes will help better the world.“Only history will determine it,” he said.A history of excellence, as iron continues to sharpen iron. 2511

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

Backpage.com, a popular website used to solicit sex was shut down by the feds this week. In Martin County, Florida, deputies are expecting more women to sell themselves on the street now as a result. As much as Backpage made it easier to buy and sell sex, investigations into the illegal trade would often start there. “Backpage, that was like the hub for us. We usually built a lot of our cases,” MCSO Lt. Jesse Carde told Scripps station WPTV in West Palm Beach in an interview. She took WPTV to where they’ll shift more attention as they expect pimps and prostitutes to do the same. “Not that they ever stopped the operations on the street but obviously we expect a little more for traffic,” she said. Generally the popular days for prostitutes to be out on the streets in Martin County are after payday, Friday and Saturday, but now with Backpage shut down, there could be changes. “People that live in neighborhoods that have in the past tended to be hotspots for prostitution, they’re going to probably see resurgence of it at least until the prostitutes, the sex workers, find a different way to use the internet,” MCSO Sheriff William Snyder said. “I’ll take you by the street where we’ve shut down a couple brothels in the neighborhood,” Carde said. These brothels would market themselves online, but also using old school methods such as business cards promoting a shell business and a wink. “As they’re passing out their cards well it’s ‘not really but come by, we’ll take care of you’ and people in the neighborhood already knew what kind of business it was,” she said. Detecting those will rely more on tips and undercover surveillance.With Backpage down, Lt. Carde says it will make it harder for traveling sex workers to find Johns. It will also help curb underage and girls forced into the trade. “I think it’s definitely a win for law enforcement that Backpage has been shutdown,” she said.  1986
