As the world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855

Attorney General William Barr has authorized federal prosecutors across the U.S. to pursue “substantial allegations” of voting irregularities before the 2020 presidential election is certified, despite little evidence of fraud. Barr’s action Monday comes days after Democrat Joe Biden defeated President Donald Trump and raises the prospect that Trump will use the Justice Department to try to challenge the outcome. It gives prosecutors the ability to go around longstanding Justice Department policy that normally would prohibit such overt actions before the election is formally certified. President Trump has not conceded the election and is instead claiming without evidence that there has been a widespread, multi-state conspiracy by Democrats to skew the vote tally in President-elect Biden’s favor.Several Republicans in charge of elections have faced scorn from their own party. Republican Philadelphia election head Al Schmidt told CBS News he has been receiving death threats after Pennsylvania was called for Biden on Saturday. Meanwhile, two Republican Senators in Georgia, both headed to their own run-off elections in January, released a statement Monday calling for the resignation of the state’s Secretary of State, Brad Raffensperger, who is also a Republican. 1286

ATLANTA — Georgia's legislature on Tuesday passed hate crimes legislation deemed essential by state leaders, sending the measure to Gov. Brian Kemp's desk.Georgia is currently one of four states in the U.S. without hate crime laws.The price Republicans exacted for moving that legislation forward was the simultaneous passage of a bill that would mandate penalties for crimes targeting police and other first responders.The action comes after Senate Republicans had added police as a protected class to the hate crimes legislation last week, but then moved those protections to a separate bill in a deal between the parties.Kemp's office said in a statement that he'd sign the hate crimes bill, pending a legal review.The bill's passage comes amid weeks-long protests against systemic racism throughout the country. The protests were sparked by the death of George Floyd, who died in police custody in Minneapolis after bystander video showed an officer kneeling on his neck for more than eight minutes.The passage also comes weeks after three arrests were made in connection with the shooting death of Ahmaud Arbery. The 25-year-old Arbery was killed in Burnswick, Georgia in February, and his case changed jurisdictions several times due to one of the suspect's connections with the local District Attorney's office. It wasn't until days after a video of the altercation leaked to the public in May that two of the men, Gregory and Travis McMichael, were arrested and charged with murder. A third man, William "Roddy" Bryan, was also charged with murder a few weeks later. 1582

Ask the residents who live there and they'll tell you that Squirrel Hill — the site of the Pittsburgh synagogue attack — is generally a happy, safe community.After all, it was Mister Rogers' neighborhood.The television icon and puppeteer and his family attended Sixth Presbyterian Church, which is just a 10-minute walk from Tree of Life, the synagogue targeted Saturday."It's a wonderful Jewish community," said Chuck Diamond, former rabbi at Tree of Life.The neighborhood is central for Jewish life in Pittsburgh, housing over 26 percent of the city's Jewish households — about 15,000 people, according to a study by the Jewish Community Foundation of Greater Pittsburgh. Another 31 percent of Jewish households lie in the surrounding neighborhoods."I think we all get together across the board, whether it's Orthodox or Hasidic or Conservative or Reform and we have wonderful Jewish communal organizations," said Diamond, who grew up and still lives in Squirrel Hill. "So it's very vibrant and very active." 1043

As the number of coronavirus cases continues to climb around the world and disrupts the travel industry, Princess Cruises has announced cancellation of early 2021 trips.“Due to restrictions and limitations with border and port access determined by government and health authorities and the continued uncertainty of airline travel,” Princess Cruises canceled about 30 voyages on two ships.The Island Princess, which stopped at ports around the world, and Pacific Princess, that sailed around South America and Australia, will not set sail until at least April, according to a release from the company.The cancelled voyages include a 111-day around-the-world from Los Angeles.Princess Cruises, which is owned by Carnival, is offering refunds or credit for a future cruise.Carnival Cruises has also canceled some 2021 voyages, and likely won’t return to full capacity until 2022.The cruise company is facing legal action for their handling of passengers when the coronavirus pandemic started this spring. Two lawsuits allege Princess Cruises did not act fast enough to impose quarantines when cases were discovered.When the lawsuits were filed in June, Princess Cruises told USA Today “our response throughout this process has focused on the well-being of our guests and crew within the parameters dictated to us by the government agencies involved and the evolving medical understanding of this new illness.” 1414
