A study that was pre-published on Wednesday indicates that a coronavirus mutation is causing the virus to be more contagious, a study authored by the Houston Methodist Hospital found. The study, however, concluded that the virus is not more potent.The study examined 5,000 COVID-19 strains from the Houston metro area. The study found very two distinct waves over the summer.The researchers found that COVID-19 infections from the second wave contained the Gly614 amino acid replacement in spike protein. The researchers said that while this amino acid caused “significantly higher virus loads,” this did not increase the potency of the virus.“We found little evidence of a significant relationship between virus genotypes and altered virulence, stressing the linkage between disease severity, underlying medical conditions, and host genetics,” the study said. “Some regions of the spike protein - the primary target of global vaccine efforts - are replete with amino acid replacements, perhaps indicating the action of selection," according to a summary of the findings.The researchers said that the study is intended to help scientists understand the composition and trajectory of future infection waves.It is important to note that the study has not been peer reviewed, and was limited to cases in the Houston area. 1326

Noemi Sandoval."They had been drinking and an argument broke out and he started hitting her and some witnesses called in to police to say a guy was hitting a woman," Sandoval said on Monday.Youd was arrested and was bailed out Monday morning between 12:30 a.m. and 1 a.m., Sandoval said. When Youd asked if he could go back to his home and pick up some belongings, he was escorted by an officer and left the home in his vehicle, police said."He then evidently went to the airplane" after leaving his home, Sandoval said.Around 2:30 a.m., Payson authorities received a call that a plane had crashed into Youd's home.Youd was a professional pilot, Sandoval said. He flew for VanCon, a construction company that owned the plane. Youd was the only person who flew it, Sandoval said.Youd's wife and her son were in the home at the time of the crash, but were able to escape Sandoval said.Neighbors who saw the crash said they couldn't believe it.

I couldn't believe it," said Buhler.Public records obtained by CNN affiliate KSTU-TV showed Youd lived at the home where the plane crashed, and he and his wife had bought the home last year. Payson police confirmed there have been previous domestic violence incidents at the home, KSTU reported. 2033
