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

ATLANTA (AP) — Marjorie Taylor Greene has won the Republican nomination for Georgia’s 14th Congressional District. She’s a businesswoman who has expressed support for the far-right conspiracy theory QAnon and been criticized for a series of racist comments. Neurosurgeon John Cowan was defeated in the primary runoff for the open seat on Tuesday. Greene's victory comes despite several GOP officials denouncing her campaign after videos surfaced in which she expresses racist, anti-Semitic and anti-Muslim views. She has responded to the criticism by blasting “the fake news media” and “the DC swamp.” Her victory comes in a deep-red area in northwest Georgia. 668

AUSTIN, Texas (AP) — Democratic presidential candidate Beto O'Rourke says President Donald Trump should resign as Congress begins an impeachment investigation.O'Rourke said Saturday there shouldn't be a fear of an impeachment probe intensifying partisan divisions. The former Texas congressman said at the Texas Tribune Festival in Austin that he believes impeaching Trump would ultimately unify the country.But O'Rourke says "the best thing" Trump can do at this point is to step down. Trump defiantly denies any wrongdoing.The 2020 Democratic presidential field is unanimous in its support of Congress for launching an impeachment investigation. The White House's handling of Trump's calls with foreign leaders is at the heart of the House impeachment inquiry.O'Rourke has been lagging in the polls but says he's in the race "until the very end." 856

Asked whether President Donald Trump had ever used the N-word, White House press secretary Sarah Sanders would not definitively say, instead referring reporters to a tweet."The President addressed that question directly," she said, adding, "I've never heard him use that term or anything similar."The question comes as former aide Omarosa Manigault Newman has claimed there's a tape of Trump using the racial epithet on the set of his NBC reality show "The Apprentice" -- though there is no evidence such a tape exists.Trump tweeted Monday night: "I don't have that word in my vocabulary, and never have."Pressed specifically on whether any recording of the President using the racial epithet exists, Sanders said: "I can't guarantee anything, but I can tell you that the President addressed this question directly."She maintained that Trump is someone who is "fighting for all Americans," and that his policies are helpful "particularly for African-Americans," citing African-American unemployment statistics.Sanders also claimed Tuesday that Trump's description of his former aide as a "dog" had "nothing to do with race and everything to do with the President calling out someone's lack of integrity."The "dog" comment was one of many insults the President has used to describe prominent African-Americans, but Sanders insisted Trump insults people of other races as well."The President's an equal opportunity person that calls things like he sees it," she said. "He fights fire with fire." 1501

Authorities in Costa Rica say that a body has been found on the Airbnb property where missing Florida woman, 36-year-old Carla Stefaniak, was staying.Costa Rica's Judicial Investigation Agency (OIJ) tells WFTS that the body was buried in a mountainous area located in the back of the property, less than 200 feet away from where Stefaniak had been staying. OIJ agents had been searching the area with specialized dogs. At this time, authorities have not been able to confirm that the body is Stefaniak.In Spanish, Walter Espinoza, the director general of the OIJ said, “the body was in a state of decomposition but the preliminary observation does verify the body is a woman.”In a press conference on Monday, Espinoza said that biological fluids consistent with blood were discovered inside the Airbnb property. The blood has been sent to labs for testing.The body cannot be positively identified by officials until an autopsy is performed.Stefaniak hasn't been seen or heard from since Tuesday, November 27. She traveled to Costa Rica with her sister-in-law, April Burton, on November 22 to celebrate her birthday. Burton flew back on November 27. Stefaniak had plans to return to the United States on November 28, bound for Florida, but never arrived for her flight. She checked into her Airbnb, located at Calle Hoja Blanca in San Antonio de Escazú, for one night on November 27. According to Burton, the last thing they knew about Stefaniak was that she was inside that Airbnb on the night of November 27. The last time Burton spoke to Stefaniak, she told her that it was raining crazy and the power went out. She continued with, "it's pretty sketchy here," according to Burton.The final photograph Stefaniak sent family members was from inside the Airbnb. Family members shared the image with WFTS, seen below.</p><p>"The guards (at the apartment complex that housed the Airbnb) told us that she left at 5 in the morning with all of her bags and got into an Uber. She wouldn’t do that, her flight was at 1:30 p.m. She’s never been early for anything in her life she wouldn’t leave to go to the airport at 5:30 a.m.," Burton said.The Airbnb listing for "Villa Buena Vista" has since been removed from Airbnb's website.WFTS spoke to Airbnb officials, who say they have reached out to Carla's family as well as the FBI, OIJ and the local embassy.Stefaniak's brother flew down to Costa Rica on Friday to search for his sister. Her father flew down to Costa Rica on Monday afternoon.This is a developing news story and will be updated as more information becomes available. 2718
