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 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

As the end of an incredibly contentious and the heated 2020 election season ends, new research suggests that Americans are more susceptible to falling prey to disinformation depending on which state they call home.For months, Bhaskar Chakravorti and his team at the Global Business School at Tufts University have been analyzing how misinformation has been spreading during this election cycle. Where a person lives often makes them a higher target to everything from fake Facebook accounts to fake Twitter accounts and even fake headlines."We are in extremely more dangerous territory now than we were two years ago," Chakravorti explained.Bad actors, the analysis found, are more likely to target people in states that are either facing hotly contested Presidential or Senate races. Chakravorti says in places like Florida, South Carolina, Kentucky, Montana and Arkansas, voters are more vulnerable to being hit with misinformation. In places like Georgia, Illinois, New Jersey and Minnesota, residents are less likely to be bombarded by false or misleading posts and stories.A person's age, education level and media consumption all weigh into the findings.Chakravorti also says that misinformation is more likely to spread and gain traction on social media."The misinformation is asymmetric in its power,” he explained. “It travels further and faster than truth and facts."Most troublesome right now, the amount of misinformation spreading about voting, from fake stories claiming people can vote after Nov. 3 to false information about mail-in ballot deadlines. Experts also say the spread of misinformation will likely continue long after Election Day.The non-profit Common Cause has also been studying the issue closely."It can result in more uncertainty when there’s already a decrease in the institutional trust and authority that many people feel with their government," said Jesse Littlewood, who works with the group.So, what's the best way to combat misinformation?Do it on the local level. People are more likely to trust information that comes directly from their city or state officials, especially about voting."It’s a real challenge for voters to stay abreast with all that changing information," Littlewood said. 2239

ATLANTA (AP) — Georgia’s governor, Brian Kemp, is explicitly banning the state's cities and counties from ordering people to wear masks in public places.He’s voiding orders that at least 15 local governments across the state had adopted even though Kemp had earlier said cities and counties had no power to order masks.The Republican governor has instead been trying to encourage voluntary mask wearing.An increasing number of other states have ordered residents to wear masks in public, including Alabama, which announced such a ban Wednesday.Kemp’s move is likely to infuriate local officials in communities that had acted, including Atlanta, Augusta, Savannah, Rome and the governor’s hometown of Athens-Clarke County. 729

ATLANTA - In a memo this week, Delta Airlines’ CEO told staff nearly 700 passengers have been placed on the no-fly list in 2020 for refusing to comply with policies requiring masks on planes.This is a sharp increase from the 460 banned passengers the airline reported in October. Delta and other airlines have been adding mask rule-breaking passengers to the no-fly list since early in the pandemic.Delta is not alone, latest numbers from United report about 430 passengers of that airline have been added to the no-fly list for not following their mask policy, and 88 have been banned from JetBlue flights.A Department of Defense study found that masks, combined with airplanes’ air filtration systems, can greatly reduce the risk of transmitting the coronavirus during a flight.While that sounds like a lot of passengers, Delta told Fox News they are flying about 1 million customers per week.In the message to staff Wednesday, Delta’s CEO Ed Bastian thanked employees for taking unpaid leave and manage reductions in hours earlier this year, which helped them be one of the few airlines that avoided involuntary furloughs. Ground workers and headquarters employees were cut to three or four days a week.However, he is now asking employees again to take unpaid leaves of absence to help the company save money, according to the staff memo. Bastian said Wednesday that Delta will need more employees to take unpaid leave “for the foreseeable future.”“I ask everyone to consider whether a voluntary leave makes sense for you and your family,” he said in a memo to employees.About 15,000 Delta employees have already left the airline through buyouts and early retirements, according to the Atlanta Journal Constitution.It's a sign of the deepening slump in air travel with coronavirus cases rising across the country. Delta expects to lose up to million a day on average during the fourth quarter.Delta is also one of the last airlines to block the middle seats on their planes, and says they will do so through March 2021.Unlike American and United, Atlanta-based Delta has avoided furloughs since the pandemic started by convincing thousands of workers to retire early or take unpaid leave.But the air travel recovery seems to be faltering. Passenger traffic rose over Thanksgiving week but has dropped since then. 2327
