A worldwide study of the coronavirus released in the journal Cell indicates that the dominant strand of COVID-19 is causing the virus to spread faster.But the study’s authors said that even though the coronavirus is able to spread faster, the virus is no more or less severe than earlier in the outbreak.The study’s authors indicate that the virus has mutated, and that the Spike protein amino acid D614G has become the virus’ dominant strand.“Our global tracking data show that the G614 variant in Spike has spread faster than D614. We interpret this to mean that the virus is likely to be more infectious,” study author Bette Korber of Los Alamos National Laboratory.The federal government’s leading infectious disease expert Dr. Anthony Fauci addressed concerns that the virus could be more contagious in an interview with The Journal of the American Medical Association on Thursday.“The data is showing there’s a single mutation that makes the virus be able to replicate better and maybe have high viral loads,” Dr. Fauci said. “We don’t have a connection to whether an individual does worse with this or not; it just seems that the virus replicates better and may be more transmissible.”Korbe explained in the study how the dominant strand of the virus differs from earlier variants.“In infected individuals G614 is associated with lower RTPCR cycle thresholds, suggestive of higher upper respiratory tract viral loads, although not with increased disease severity,” Korbe said. “These findings illuminate changes important for a mechanistic understanding of the virus, and support continuing surveillance of Spike mutations to aid in the development of immunological interventions.”To read the full study, click here. 1731

ALPINE, Calif. (KGTV) - An Alpine woman who tested positive for COVID-19 says her quarantine turned into a nightmare as a postal carrier delivered a package.This past weekend, Tamica got a COVID test after three co-workers tested positive. She also tested positive and remains asymptomatic."Since I got that Sunday, I've been quarantining at home," said Tamica.On Tuesday, past 1 p.m., as the mail truck pulled up to her apartment off Tavern Road, her two 80-lb. dogs ran to the front door and started barking. She says the door was open but the screen door was shut, as the postal carrier stood outside, at the door, with something in his hand."They were instantly pawing at their face and backed up, and acting weird ... jumping up and down and making a whining noise," said Tamica.Tamica believes the postal carrier had used his pepper spray. At that point, Tamica says the dogs jumped on the door and pushed it open. They ran out, and she ran after them. Tamica says the letter carrier sprayed toward one dog as it ran off, before turning to her other dog."I just jumped in front of my dog. He's wasn't doing anything. He wasn't barking. He was just sitting there .... He's a golden retriever and very friendly ... The postal carrier is spraying us, yelling and just spraying wildly," Tamica said.Tamica says that went on for about a minute, and it seemed liked forever."I was mad, scared, ready to cry … yelling at him to stop, stop, stop!" said Tamica.She says he finally did. Her dogs' eyes were left shut and stinging for hours. Her eyes were also ripe with pain. Tamica filed a complaint with the Postal Service."It's outrageous. This was not warranted at all," said Tamica.A different version of events has emerged from the postal carrier's statements.According to a USPS spokesperson, he claims he never sprayed through the screen door, didn't intend to pepper-spray Tamica, and only started spraying when both dogs were outside, lunging at him, to allow him to "leave the area."The spokesperson adds that based on the statements collected, they are standing by their postal carrier's version of events. They did apologize for Tamica getting pepper-sprayed in the incident.They also issued the following statement:"The Postal Service places the safety of its employees as a top priority. Letter carriers fearing for their safety due to a loose or unrestrained pet may stop delivery and ask homeowners to pick up their mail at the Post Office until the pet is restrained. In cases where a carrier sees a dog roaming and can’t discern where it resides, delivery could be interrupted to the entire neighborhood.In 2019, San Diego ranked #10 in the country for dog attacks on letter carriers. Dogs can be protective of their territory and may interpret the actions of letter carriers as a threat. Please take precautions when accepting mail in the presence of your pet. When a carrier comes to your home, keep your dog inside, away from the door in another room. Any dog can bite. Even the friendliest dog may bite when startled or surprised. If the dog is physically or mentally unhealthy, is in pain, feels threatened, or is protecting its food or a favorite toy, it can bite.The letter carriers at your local Post Office deliver every day. And if you are a dog owner, we need you to deliver for us, too. Keep your dog on a leash or away from the door, so that your letter carrier can safely deliver to your mailbox or porch, today and every day." 3464

ABSARD, Iran (AP) — State television says an Iranian scientist was killed in a targeted attack killed in Absard, a small city just east of the capital, Tehran. State TV says the attack on the scientist, named Mohsen Fakhrizadeh, saw gunmen use explosives and machine gun fire. He was attacked by "armed terrorist elements," according to state TV, and died at a local hospital after first responders couldn't revive him.Israel has alleged the man led the Islamic Republic’s military nuclear program until its disbanding in the early 2000s.Iran’s foreign minister is alleging the killing of Fakhrizadeh has “serious indications” of an Israeli role. Mohammad Javad Zarif made the statement Friday on Twitter.“Terrorists murdered an eminent Iranian scientist today. This cowardice—with serious indications of Israeli role—shows desperate warmongering of perpetrators,” Zarif wrote. "Iran calls on int'l community—and especially EU—to end their shameful double standards & condemn this act of state terror."Israel declined to immediately comment on the killing of Fakhrizadeh, who Israeli Prime Minister Benjamin Netanyahu once called out in a news conference saying: “Remember that name.”Israel has long been suspected of carrying out a series of targeted killings of Iranian nuclear scientists nearly a decade ago. 1323
