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understand the composition and trajectory of future infection waves.It is important to note that the study has not been peer reviewed, and was limited to cases in the Houston area. 1326

A Pennsylvania man is facing criminal charges for allegedly requesting and casting ballots for dead relatives.The Delaware County District Attorney announced the charges against Bruce Bartman Monday.“We are charging him today with two counts of perjury for making false statements to register two deceased individuals who are his relatives both his mother and his mother-in-law. He made false statements through the state’s assure system to register them as voters and he’s also charged with making an unlawful vote because he actually submitted an absentee ballot for his deceased mother, a ballot that was counted,” District Attorney Jack Stollsteimer said at a press conference.Stollsteimer says both women were registered as Republicans and Bartman told investigators he had done so to help reelect Donald Trump.Bartman reportedly used the driver’s license number for his mother, who died more than a decade ago, and was able to obtain a ballot.Prosecutors say he used his mother-in-law’s social security number to register her for the general election, and the system returned a deceased record for her prompting the state to send a confirmation letter to the address to confirm the information, according to WPVI.Stollsteimer’s office says Bartman falsified this confirmation letter and returned it to register his mother-in-law to vote. He did not obtain a ballot in her name, according to prosecutors.“In his political frustration, he chose to do something stupid,” Bartman’s lawyer, Samuel Stretton told the Philadelphia Inquirer. “And for that he is very sorry.”Stollsteimer said there was no evidence of widespread voter fraud in Delaware County and this was the only case of voter fraud during this election his office has encountered. However, they have had scores of leads investigators have followed up on.Investigators said rumors on social media about a dead voter in Delaware County led to a complaint filed with the county’s Board of Elections. A task force followed up and found evidence of a crime, according to the Philadelphia Inquirer.This incident is the third instance of reported voter fraud in Pennsylvania since the election last month, the Inquirer reported.Previous reports include a man who cast two ballots on Election Day, one for himself and one in the name of his son, and of a man who allegedly applied for a ballot for his dead mother. No word if the ballot was cast. 2413

A subject coughing in a cyclic incident. Top view of airborne droplet transmission with and without wearing a surgical mask. The top and bottom figures show the results at 4 s and 5 s, respectively. We consider a surgical mask that exhibits an initial efficiency of ～91%. The cover does not prevent the transport of the saliva droplets entirely away from the subject. Many droplets penetrate the mask shield and some saliva droplet disease-carrier particles can travel more than 1.2 m. For visualization, the droplets were scaled by a factor of 600 compared to their actual size. The environmental conditions are zero wind speed, ambient temperature 20 °C, pressure 1 atm, and relative humidity 50%. The mouth temperature is 34 °C, and the face skin temperature is 32 °C. 779

A mother charged with killing her two young sons by placing them in an oven and turning it on was expected to appear in court on Monday but was not at the appearance.Investigators say 24 year-old Lamora Williams put her sons, ages two and one, into an oven and turned it on. The toddlers, 1-year-old Jakarter Penn and 2-year-old Keyounte Penn, had burns on their bodies when police found them at the Oakland City West End Apartments in Atlanta.Lamora Williams' family said she struggled most of her life with mental issues and may have been dealing with postpartum at the time of the incident.It’s a tragedy which her sister thinks could have been prevented.“She had issues and the fact that the state failed her, that’s a problem,” said Tabitha Hollingworth.Plus, family say the writing was on the wall. She routinely left her children home alone and had even attempted to cut her wrists.Wearing dark sunglasses to hide her tears, Brenda Williams is saddened, but not surprised that her daughter is now charged with murder.“Mora wasn’t right, she hasn’t been right and what happened three months ago, that the kids father left her, I told him something tragic is going to happen. She’s going to do something to those kids, she’s going to do something to herself,” said Brenda Williams.Williams is charged with two counts of murder and one count of cruelty to children in the first degree. Her next court appearance is scheduled for November 8.  1458
