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 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

At least 92 people in 29 states have been infected with a strain of multidrug-resistant salmonella after coming into contact with a variety of raw chicken products, the U.S. Centers for Disease Control and Prevention said Wednesday. Twenty-one of the sick patients have been hospitalized, though no deaths have been reported.The source of the raw chicken is unclear from lab tests, and no single common supplier has been identified. The strain has shown up in samples from a variety of raw chicken products including pet food, chicken pieces, ground pieces and whole chickens. The bacteria have also been found in live chickens. The U.S. Department of Agriculture's Food Safety and Inspection Service is monitoring the outbreak, and the CDC's investigation is ongoing.This particular salmonella strain is resistant to multiple antibiotics, the most common form of treatment.People sick with this strain have experienced stomach pain, cramps, diarrhea and fever 12 to 72 hours after exposure to the bacteria.Most people infected with salmonella, the most frequent cause of foodborne illness, get better in four to seven days without treatment. Symptoms can be worse for people with underlying medical conditions, children under 5 and people older than 65, as they typically have weaker immune systems.The CDC says the outbreak started in January, and more people have tested positive for this strain through September.The patients live in California, Washington, Texas, Nebraska, Missouri, Minnesota, Illinois, Indiana, Michigan, Ohio, Kentucky, Tennessee, Alabama, Louisiana, Georgia, Florida, South Carolina, North Carolina, Virginia, Maryland, Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Hawaii, Massachusetts and Maine.Keep in mind that poultry can spread germs any time you handle it, the CDC notes, so always wash your hands when handling raw meat or poultry. Don't wash chicken before you cook it, as doing so can spread germs to other surfaces. Wipe down surfaces that have come into contact with raw meat, and use a separate cutting board. Cook chicken to a temperature of 165 degrees Fahrenheit to kill harmful bacteria.Some people may like to feed their cats and dogs raw chicken, but the CDC recommends against it. Germs in the food can make your pets sick, and you can get sick handling it.If you keep chickens as pets, getting too friendly with your fowl is also not recommended. Costumes may look cute on cats and dogs, but the CDC suggests that you avoid dressing your chickens up or cuddling with them to keep from being exposed to these bacteria. 2600

Bad news: There is a small chance an asteroid will collide with Earth. The good news: Mankind has more than 115 years to prepare for it. According to a Washington Post report, NASA is preparing for possible tactics to deflect the asteroid Bennu, which will approach Earth Sept. 21, 2135. As of today, NASA rates Bennu's chance of striking Earth at one-in-2,700.The asteroid is roughly 1,600 feet in diameter, and would not be an Earth-ending event if it struck. But that doesn't mean it couldn't cause damage, especially if it struck near a populated area. Bennu is likely dozens of times larger than the object that struck near Chelyabinsk, Russia in 2013, causing hundreds of injuries, and thousands of broken windows. The event caused nearly million in damage to roughly 7,000 buildings. The 2013 event shows that even small objects are capable of causing massive damage. In 2016, NASA launched OSIRIS-REx, which will land on the asteroid and bring back samples. The information gathered could help NASA decide what steps it would take to deflect the asteroid. According to the Washington Post, NASA is working on a plan called the Hypervelocity Asteroid Mitigation Mission for Emergency Response, or HAMMER. NASA's HAMMER plan could involve using a nine-ton bulk impactor to push Bennu out of Earth's path. Another idea would be straight out of the movie "Armageddon," using a nuclear-type device to move the asteroid. A NASA engineer involved in the study told the Washington Post all of these ideas are theoretical. “We’re doing these design studies to prepare ourselves, so if we do find a threatening object, we’re better prepared to deal with it,” Brent W. Barbee, NASA engineer, told the Post.To read the Washington Post's full report, click here.  1855
