Are you a COVID super spreader? Ivanhoe Newswire Updated:  Tags:  The COVID vaccine is rolling out across the country, but medical experts say this is not the time to let our guards down. Now, scientists have uncovered some of the factors that may make one person more likely to spread the virus than another. From rocket propulsion ... to sneeze propulsion! These mechanical engineers are adapting their skills in the fight against COVID. “Fluid properties drive how well things turn into aerosols,” explained Michael Kinzel, assistant professor of mechanical and aerospace engineering at the...

Dec 31 2020 Read 3969 Times Sneezing is one of the fastest ways to spread a virus, with the action launching microdroplets into the air where they can then contaminate people and surfaces. New research from the University of Central Florida (UCF) reveals just how dangerous sneezing can be, with a team of scientists identifying a suite of features that can make an individual a “super-spreader”. Using computer-generated models and working from the Department of Mechanical and Aerospace Engineering, the team simulated sneeze actions in a variety of different people. They focused specificall...

Is Plexiglas keeping COVID-19 out? New Princeton study gives a clearer picture. Updated Dec 16, 2020; Wedged onto kindergarteners’ desks, professors’ lecterns and cashiers’ counters, Plexiglas barriers have become a ubiquitous COVID-19 precaution, nearly as pervasive as masks and hand sanitizer. But the jury’s still out on how effective they are in subduing the virus. In experiments showing how air particles can travel around the barriers, a research group led by Howard A. Stone, a professor of Mechanical & Aerospace Engineering at Princeton University, has been studying Plexiglas’...
