Longer-lingering droplets are less efficient carriers of COVID-19 virus

Longer-lingering droplets are less efficient carriers of COVID-19 virus

Science
Oct. 27 (UPI) -- New research -- published Tuesday in the journal Physics of Fluids -- suggests bigger, short-lived aerosol droplets pose a much greater risk of spreading COVID-19 than aerosol microdroplets, which are tiny particles that linger longest in the air. To better understand the behavior and virus-carrying potential of different types of aerosol droplets, researchers had volunteers breathe, speak and cough into a laser beam, which recorded the size and distribution of the array of aerosolized particles. Advertisement Researchers used a Rayleigh jet nozzle chip to generate the same distribution of droplets. The jet released aerosol droplets composed of 1 percent glycerol and 99 percent ethanol into a chamber. A sheet of laser light running across the middle of the chamber allowed...

GULLIVER is rarely fazed by what happens below the line of his posts. Receiving the occasional shoeing from readers—sometimes insightful, sometimes not—goes with the job. And he has certainly found his views swayed by well-reasoned arguments he finds there.But he was truly gobsmacked at the discussion that ensued from a piece last year about the sexualisation of flight attendants. The post noted a few of the seedier airline hiring practices, such as asking potential recruits, some just 15, to take part in a bikini competition, or carriers refusing to employ married women. It then concluded with what seemed to be an uncontroversial suggestion: female cabin crew should be chosen for their abilities, not for their allure.It turns out that such woolly liberal thinking is merely the product of ...
