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

At least three people have died, including an alleged gunman, after gunfire erupted at a home in Port St. Lucie in southeastern Florida. Officers on scene said a chilling 911 call came in Monday afternoon, a girl said someone was inside her house shooting people.At about 1:15 p.m. ET Monday, the city’s police department advised the public to stay away from the scene on Morningside Blvd. near Morningside Elementary School. Around 3:30 p.m. ET, officers reported a man and 13-year-old girl found at the home had died. Two others found at the scene were taken to a nearby hospital. An officer was injured, and is expected to be OK. A SWAT Team then made entry into the home and found the suspected shooter dead in an upstairs bedroom. Police say it was a dispute about the alleged gunman's dog that started the incident. 830

As some companies consider making work-from-home permanent, others see the value in creating a workplace for employees. "We've always been flexible in our workplace, we've always allowed people to work from home if they want, and what we learned is that people do want a place that is their own that we can come into," said Reid Carr, CEO of the marketing agency Red Door Interactive. After years of leasing an office in downtown San Diego, the company wanted to create its own space, designed to foster collaboration and growth."We were excited when we found it, we had a vision for how this whole process was going to go down," said Carr. The company purchased nearly half an acre of property to create a campus-style workplace. But after the pandemic hit, they overhauled the design to ensure it was a space employees not only wanted to go to but could feel safe in.The new campus will incorporate touchless features throughout the buildings, like doors and water bottle filling stations. They're creating outdoor meeting spaces with heaters and shades so that they can be used year-round. And inside, they're investing in the best available HVAC systems for air filtration."I'm learning at all this stuff as we go, but we're looking at hospital grade stuff. The perspective we took is there's always going to be flus and colds, so why not do these things that will help keep people from spreading disease," said Carr. In addition to having their own socially distanced desks, employees will have designated areas separate from visitors, including the kitchen. One building will be the epicenter of conference rooms so they can be easily cleaned more frequently."Certain things never change. You want to feel like you belong to something, you want to connect with people," said Carr. The company plans to break ground on its new campus in early September, with plans to complete the project in April 2021. 1916

As states begin to reopen, a new stage in the pandemic means elective surgeries are back on schedule.For 51-year-old mother of two Honaire Murillo, the pandemic delayed a much needed spinal surgery.“The shooting pains all the time and you know I had kids I have to run around. And so, it took about a year and I was so disappointed,” says Murillo.Twenty-four years ago, the aspiring pro-bodybuilder’s dreams were cut short when she was hit by a motorboat while visiting Puerto Rico on business.More than 20 surgeries later, Murillo needed another one.“The pain started coming back and so I knew I was going to have more surgery,” she says.Last week, doctors at Rush University Medical Center’s Midwest Orthopaedics in Chicago were able to get Murillo into surgery for a first-of-its-kind procedure.It was a minimally invasive spine surgery that utilized augmented reality.“The efficiency this provides because of the accuracy and the visualization of the spine is remarkable,” says Dr. Frank Phillips, the director and minimally invasive spinal surgeon at Rush who performed the procedure.A headset guidance system allowed Dr. Phillips to see Murillo’s spinal anatomy – essentially giving him X-ray vision.“That's exactly what it is,” says Dr. Phillips. “It really is X-ray vision. Except it's not just X-ray vision, you're actually seeing the real spine through the skin.”The CT scanned images are directly projected onto the surgeon’s retina and then superimposed right on top of the patient’s surgical area.“I was just blown away,” says Dr. Phillips. “The minute I put my headset on and looked down at the spine it was like that wow moment. I was like ‘this is crazy.’”Researchers say the FDA-cleared x-vision system could revolutionize the way surgeons perform complex procedures.“It's so accurate so precise the visualization so good you can do the surgery more efficiently which obviously translates into less anesthetic time and advantages to the patient,” says Phillips.For Murillo, who eventually went pro 15 years after her accident, this latest groundbreaking surgery has her thinking about another return to competition.“I'm still looking to see if I could comeback one more time. I'm not sure. But, yeah to me it's a dream.”Augmedics, the maker of the technology says it plans to explore the x-ray vision technology beyond just spinal surgery. 2365

As we shield ourselves in any way possible from the novel coronavirus, there are some parts of the country handling social distancing better than others.“This is a public health problem; it’s not a private health problem,” explained Dr. Bhaskar Chakravorti, who leads the Fletcher Institute for Business at Tufts University. “If I get sick, I could make three other people sick.”Over the past few months, Dr. Chakravorti and his colleagues have been analyzing mobility data from across the country.What did he and his team discover?The top three states who were practicing social distancing the most were New York, New Jersey and Massachusetts. Nebraska, South Dakota, Arizona were among the worst when it came to practicing social-distancing procedures. Dr. Chakravorti says that has led to higher contagion rates in those areas.“In this post-pandemic moment, each state is going in somewhat a different direction as far as how it's managing the pandemic,” he added.In bigger cities with higher rates of infections, the study found that people responded better to restrictions because they could see the impact the coronavirus was having around them. Dr. Chakravorti hopes public health officials use his findings to make more uniform policies nationwide.“This whole issue of COVID has become a political issue, so even the act of wearing a mask has become a political statement,” he said. “You never want to mix politics with anything. You definitely don’t want to mix it with public health. That’s a dangerous combination.” 1534
