The new of the virus is more contagious than other strains.The CDC said because of restrictions in place since March, air travel to the U.S. from the U.K. is down by 90%. 692

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

As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150

As of today, at least 17 children have died already this year due to vehicular heat stroke – and the hottest days of summer still await. Now is the time to pass the Hot Cars Act (H.R. 3593) and assure that dozens of families will no longer have to experience the anguish of losing a child in these preventable incidents each year. 339
