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

Astronaut Nick Hague was ready for a mission that would send him and cosmonaut Aleksey Ovchinin to the International Space Station to join a crew of three that was already on board the station. But just minutes into last week's flight on board the Soyuz MS-10 craft, the crew needed to abort the mission due to a booster failure. The incident marked the first aborted flight of a Soyuz craft in more than four decades. On Wednesday, Hague described the harrowing moments that followed after the booster's failure. “We were tossed back and forth inside the capsule a little bit and thrusted away from the rocket as soon as the launch abort system had recognized there was a problem with the booster," Hague said. That is when Hague's training and past as a US Air Force pilot kicked in. “My career in the Air Force has done a lot to help me prepare for stressful situations like this, whether it’s through deployments or my time in flight test where we have had to deal with failures in aircraft that you’re in and having to get down on the ground immediately,” he said. “We train endlessly to address those types of situations."After surviving an incident at 30 miles above the ground, Hague plans on making another attempt to visit the International Space Station in 2019.   1338

As we're all on screens now more than ever, new data suggests a difference in opinion between teens and their parents. Turns out, there's an increase in teens hiding their online activity from mom and dad.“I think pretty early on my husband and I decided that it wasn’t for us,” Stephanie Murphy said, talking about devices. Video games, iPads, Nintendo, you name it, she doesn't want it in her house. The 2nd grade teacher in New York City is also a busy mom of 4. Only her 13-year-old daughter has access to a device.“She’s not the majority, she does have a phone we did give her one when she went into middle school for safety reasons,” Murphy said.Murphy knows her family isn't the majority either. For the second year in a row, AT&T and Quadrant Strategies teamed up to conduct their "digital family poll."“We do it to benchmark what teens are doing online, how are teens interacting online, and how are parents looking at the digital life of their kids,” said Nicole Anderson. She's the Assistant Vice President for Social Responsibility at AT&T. This year's data was interesting in comparison to last year, when there wasn't a pandemic.“From last year to this year - parents actually feel more confident: 71% felt more confident than at any point they could see what their teens are doing online. They’re spending more time together so parents felt more confident. 'I can check anytime and see what they’re doing,'” Anderson said.But, add that stat to the one they got from teens, who also felt more confident that they could do a better job at hiding things. “Seeing that discontent made us want to double down saying we’ve got parental controls; we have resources you can use on the screen ready website,” Anderson said.The poll, which focuses on teens, also found that parental controls made a difference. And not just an obvious one.“The teens who do have parental controls on their devices reported that they’re happier; feel safer, more productive, and they’re able to follow their passions online and digitally more so then these teens who don’t have parental controls set,” Anderson explained. We asked about those parental controls, and where one would even begin. "You can set a time limit that your child spends on a device, it can screen by age what sites are appropriate and it can block certain programming depending on the device," Anderson said.AT&T launched a new parental controls campaign using super heroes. She says the controls take away the fight between kids and their parents.As for Stephanie Murphy, she says, “I’m going to be honest, they are going to search. I’m hoping I’m instilling that they come to me and ask me questions.” She says she's armed and ready with answers and she also says, what's most important for her family is being present.“When they were online, they’re near me. When they were working on their computers, they’re right next to me, when he finished it was to talk to his friends and he was in another room and I could hear them. They were never where they were so far that I couldn’t hear what they were doing,” Murphy said.Murphy says, when and if that day comes, she'll launch parental controls. But for now, in these challenging times, remind yourself that no one has parenting down to a perfect science.“Everyone is different and everyone is in a different situation. I’m not in a position to give advice, but I could just say that you do what’s best, they’re your children and you know them best.” 3481

At least five Marines assigned to the prestigious ceremonial Silent Drill Platoon in Washington were placed in pretrial confinement in recent days due to allegations they were involved in hazing at least one Marine at the unit, according to three defense officials.Hearings that took place this week resulted in one Marine being released from confinement but all could still face charges as the Naval Criminal Investigative Service has taken over the matter.The number of alleged victims has not been made public but the allegations came to light when one Marine came forward. Officials say a video had been made allegedly showing some Marines hitting at least one other Marine. It is not publicly known if that victim is the Marine who came forward.The platoon is a 24-man rifle unit that performs a drill exhibition largely in silence. It was founded in 1948 and performed for presidents and top officials as well as communities around the country tossing and spinning 10-pound M1 rifles with fixed bayonets.Multiple performances of the drill team were canceled in recent weeks due to the ongoing investigation, according to officials. The Marines did not publicize the reason for those cancellations or which performances were affected. The Marines said they began an investigation immediately at the unit, before turning it over the NCIS.The unit and the Marines are well known in the Washington community where they reside. In September they gained attention when several Marines ran to a nearby apartment complex to help rescue elderly residents when it caught fire. 1580
