How do we get infected with the coronavirus? Japanese researchers have used a supercomputer to simulate how viral particles move. The simulation makes the invisible threat visible and could help people evaluate risk of infection. Their findings show how far even the smallest droplets can spread and demonstrate how masks, social distancing and humidity impact the spread of COVID-19. Their research suggests that the use of humidifiers may help limit infections indoors during times when regular ventilation isn’’t possible.
Southeast Asia is the source of 95 percent of global cassava exports, and the detection in 2015 in Cambodia of the potentially harvest-devastating Sri Lankan cassava mosaic virus (SLCMV) raised alarm. By 2016, the disease, which cannot always be detected visually, had spread, showing its potential to become a major threat to the livelihoods of millions of smallholder farming families.
