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 the school year comes to a close, students will find many ways to thank their teachers.One student in Lackawanna County, Pennsylvania may have found the best way, by helping his teacher win a new car.Students at the Career Technology Center of Lackawanna County were more than happy to head outside to the parking lot on a beautiful day. The short field trip was about to become a lot sweeter for one of the CTC's teachers, who was awarded the title of Burne Honda's Teacher of the Year.Kyle Linko, a welding technology teacher at the school in Scranton, took the title and the grand prize: a brand new Honda Civic. 631

ASHLAND, Ore. -- In the Rogue Valley of southern Oregon, you’ll find rows upon rows of vineyards. Rob Folin is the winemaker at Belle Fiore in Ashland.Although the grapes are different, the dry climate is similar to Napa Valley, making it very ideal conditions for wine-making. However, just like other crops, the weather can have a huge impact on wine grapes. As a winemaker, Folin says he needs to know what his vineyards are facing and how to handle what Mother Nature throws at him.“Rain, snow, frost, smoke, fire, we’ve got it all,” Folin said.In the summertime, it can be clear one day and smoky the next.“Right during harvest or right before is when it’s the worst time to have smoke – which would be right now,” Folin said.Harvest season in southern Oregon typically starts in mid-September and goes until mid-October. Folin says one of the stressors for a winemaker is smoke taint. That’s when smoke gets trapped in the skin of the grapes giving them a campfire aroma and ashy texture. It’s a flavor very few people enjoy.“If your vineyard had a fire right next to it and you just had solid smoke coming in there, then you can really have this barbecue or campfire kind of aroma,” Folin said.Unless you send your grapes in somewhere to get tested, Folin says there’s no way to know your grapes have smoke taint until they go through fermentation. He says whether a grape is impacted or not depends on a lot of factors, and it’s very unpredictable.“Our vineyard here could be totally fine, and the one across the street, their resulting wines could be smoky, like it’s just how the wind goes, the intensity of the smoke, how long it was there, how close it was, did it settle overnight.”When it comes down to it, there’s only so much you can control. As of right now, not much can be done to prevent smoke taint, and smoky summers in the western U.S. seems to be the norm lately.Folin says winemakers that face a lot of smoke taint can make more white wines since white wines are fermented without the grape skin. Or they can market their wines to consumers as a smoky wine for those that like the taste. At the end of the day, Folin says winemakers have to go with the flow.“Just roll with it," Folin said. "Ya know, fix what you can. If you can’t do anything about it, what can you do? Do what you can do and move forward.”With the exception of one fire near the vineyard in the past month, Folin says it’s been a very great year for his vineyard. He’s hopeful something good can come out of 2020 after all.“With all the stuff that’s going on, maybe we’ll have the best grapes this year. I don’t know. Just going to count on that.” 2649

AURORA, Colo. -- When Amy and Marco Becerra adopted a 3-year-old Peruvian girl last April, they had no idea what kind of ordeal it would be to get approval for her to stay in the U.S.The Aurora couple, both U.S. citizens, had been living in Peru and had been taking care of their adopted daughter Angela since she was 12 days old.After getting clearance from the Peruvian courts to adopt Angela, they began planning to come back to the U.S. But Angela's application for immigration kept getting delayed."We had been reaching out to USCIS (United States Citizenship & Immigration Services) for over a year, asking and sometimes begging, and sometimes crying for help," Amy Becerra said. She said the people answering USCIS's 1-800 number would simply recite what was on their website, and that some of the information conflicted with information on another government agency website.Tourist VisaThe Becerras brought Angela to Colorado on a tourist visa, and continued their efforts to get Immigration officials to grant her citizenship.Earlier this month, they learned their request had been denied.It came as a shock."No one can believe that would happen to two U.S. Citizens," Amy Becerra said.The couple went public with their plight.Congressman gets involvedRepublican Colorado Congressman Mike Coffman then got involved. "What a broken immigration system that would even think about deporting a 4-year-old," Coffman said.On Thursday, Coffman held a news conference to announce that USCIS had reversed course."They said they re-opened it due to the complexities of the case," he said, adding that he believes the agency bowed to public pressure which was a result of all of Amy Becerra's hard work.The Becerras will now be able to reapply for Angela's citizenship papers.The Congressman's Communications Director Daniel Bucheli said it should be automatic since both parents are U.S. Citizens.He said Coffman offered to pay the ,040 application fee out of his own personal account."I feel very grateful," Marco Becerra said. "Another big door is open for my family. I'm feeling no more stress."Now, 4-year-old Angela can grow up knowing that her home is in Aurora, Colorado. 2301

At least seven people were killed in northwestern New Mexico when a tractor-trailer crashed head-on with a nearly packed Greyhound bus, officials said."We do expect that number to rise," New Mexico State Police spokesman Officer Ray Wilson said on Thursday. Dozens of passengers were seen trying to climb out of the windows of the bus while some bystanders walked among piles of debris carrying ladders.Most of the 49 people on the bus, including adults and children, were taken to area hospitals with different degrees of injuries. The driver of the truck sustained injuries that were not life-threatening, the state police said.Wilson had initially said six people suffered minor injuries.As of Thursday night, seven deaths had been confirmed. In a statement, the New Mexico State police said their identities would not be released until their next of kin were notified.The horrific scene began around 12:30 p.m. when a semi truck was traveling eastbound along Interstate 40 in McKinley County and it blew a tire. The driver lost control of the vehicle, which crossed the median and struck the westbound bus, Wilson told reporters.Aerial footage by CNN affiliate KRQE showed the bus damaged on the front edge, but upright, in the grass median. Nearby was an overturned vehicle and the truck trailer on its side, with what appeared to be produce boxes spilled on the median.One witness, Chris Jones, was driving along the highway when he came upon the crash site. He quickly jumped out of his car to help the injured when he didn't see any ambulances around."Just trying to help them, comfort them, calm them down, get them taken care of until EMS got there," Jones told CNN affiliate KCAL.Jones, who has medical training as Navy veteran and volunteer firefighters, said he first tried to get an idea of who was hurt.Another witness, Marc Gonzales, said the scene was a "complete catastrophe," with skid marks on the side of the road. Passengers tried to climb out the bus windows and bystanders grabbed ladders from their vehicles to try to rescue them, he said."It's by far one of the worst accidents I've encountered. ... It was horrible," Gonzales told KRQE."You could tell that people were distressed, screams were coming from the bus," he said.Twenty patients were initially taken to the Gallup Indian Medical Center in Gallup, acting chief medical officer Dr. Kevin Gaines told reporters. Some families were among the patients, as well as four children, he said.Ten patients were being treated for injuries ranging from broken bones to bruises, he said. One was in critical condition and two were in serious condition, Gaines said.Six patients were released and four others were transferred to other medical facilities in New Mexico and in neighboring Arizona, Gaines said.The Los Angeles Greyhound bus had originally departed from St. Louis and had just made a stop in Albuquerque prior to the crash, the company said."Our first priority is taking care of our passengers and their families as this incident has deeply impacted all involved," the company said. "Our thoughts and prayers are with everyone as we continue to give our support to all affected.The National Transportation Safety Board said it was sending 10 investigators to the site.This is not the first deadly crash involving a passenger bus in the state in recent months.In July, the driver of a passenger bus tried to avoid a crash along I-25 near Bernalillo, but lost control and rolled crossing the highway. The it bus was then plowed by a semi truck traveling in the opposite direction. Three people were killed in that crash, CNN affiliate KRQE reported.Correction: An earlier version of this story misstated the route of the bus. The story has been updated to reflect that the bus made a stop in Albuquerque before the incident. The-CNN-Wire 3829
