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

At age 106, Sen. John McCain's Roberta McCain mother will be in attendance at the late senator's funeral this Saturday in Washington, D.C., and his burial service in Maryland, the Associated Press reported. Roberta McCain has outlived the son she called "Johnny," as the U.S. Senator from Arizona died on Saturday at the age of 81. Sen. McCain will be lain in state at the U.S. Capitol on Friday before his final services on Saturday. Roberta McCain, at age 96, was active on the campaign trail for her son during his presidential bid. She also made a number of appearances on television, including one controversial spot on MSNBC's Hardball, where she went after fellow GOP presidential hopeful Mitt Romney. Roberta McCain had an identical twin sister, Rowena Wright, who died at the age of 99 in 2011.  842

ATLANTA, Ga. – While residents along the Gulf Coast seek shelter from Hurricane Laura, they should still keep the threat of COVID-19 in mind.Emergency managers, shelter managers, and public health professionals are taking measures to reduce the possible spread of the coronavirus among people who seek safety in a disaster shelter during severe weather events like this.For those staying in a shelter during the storm, the Centers for Disease Control and Prevention (CDC) offered some tips to lower the risk of coronavirus infection:Preparing to shelterIf you need to evacuate, the CDC says to prepare a “go kit” with personal items you cannot do without during an emergency. That includes items that can help protect you and others from COVID-19, like hand sanitizer with at least 60% alcohol, soap, disinfectant wipes, and two masks for each person.Know a safe place to shelter and have several ways to receive weather alerts, such as the National Weather Service’s cell phone alerts, NOAA Weather Radio, or NWS alerts on Twitter.Find out if your local public shelter is open, in case you need to evacuate your home and go there. Your shelter location may be different this year due to the COVID-19 pandemic.Follow guidance from your local public health or emergency management officials on when and where to shelter.Make a plan and prepare a disaster kit for your pets. Find out if your disaster shelter will accept pets. Typically, when shelters accommodate pets, the pets are housed in a separate area from people.Follow safety precautions when using transportation to evacuate. If you have to travel away from your community to evacuate, follow safety precautions for travelers to protect yourself and others from COVID-19.While in a public shelterPractice social distancing. Stay at least 6 feet from other people outside of your household.Follow CDC COVID-19 preventive actions—wash your hands often, cover coughs and sneezes, and follow shelter policies for wearing masks. Avoid sharing food and drink with anyone if possible.Follow disaster shelter policies and procedures designed to protect everyone in the shelter, especially those who are at higher risk for severe illness from COVID-19, including older adults and people of any age who have serious underlying medical conditions.Avoid touching high-touch surfaces, such as handrails, as much as possible. Wash hands with soap and water for at least 20 seconds or use hand sanitizers with at least 60% alcohol immediately after you touch these surfaces.Keep your living area in the shelter clean and disinfect frequently touched items such as toys, cellphones, and other electronics.If you feel sick when you arrive at the shelter or start to feel sick while sheltering, tell shelter staff immediately.Keeping children safe in sheltersTeach and reinforce everyday preventive actions for keeping children healthy.Make sure children aged 2 and older wear masks. Masks should not be used by children under the age of 2. They also should not be used by people having trouble breathing, or who are unconscious, incapacitated, or unable to remove the mask without assistance.Be a good role model—if you wash your hands often, your children are more likely to do the same.Help your children stay at least 6 feet away from anyone who is not in your household.Watch your child for any signs of illness and tell shelter staff if your child may be ill.Try to deal with the disaster calmly and confidently, as this can provide the best support for your children. Help children cope with emergencies. 3559

Australian scientists are searching for the remnants of a meteor which burned spectacularly across the sky in Perth Tuesday night.The unusual phenomenon was caught on camera by multiple spectators, and described as a "fireball" on social media.Curtin University professor Phil Bland told CNN it was "almost certainly" a chunk of asteroid coming through the atmosphere, an event which he said occurs only a couple of times a year. 437

As part of the response to one of the deadliest school shootings in US history, Broward County Sheriff Scott Israel told reporters on Wednesday that deputies that patrol high schools in the county will be equipped with rifles. The announcement came on the same day that President Donald Trump called for an end for schools being considered "gun-free." As part of a discussion, which included the families of the 17 people killed during last week's Florida school shooting, Trump suggested that school staff carry guns. "This would be obviously only for people who were very adept at handling a gun, and it would be, it's called concealed carry, where a teacher would have a concealed gun on them. They'd go for special training and they would be there and you would no longer have a gun-free zone," Trump said.  839
