Editor's Note A study by the Riken research institute and Kobe University using Fugaku, the world’s fastest supercomputer, finds that wearing two masks offers little benefit in preventing the spread of COVID-19 compared to one well-fitted disposable mask, the March 4 Reuters reports. The researchers found that tightly-fitted surgical masks…
