Infectious particles can spread beyond 6 feet when someone with COVID-19 coughs without a mask, study suggests

How far and quickly smaller droplets travel when a person coughs varies, according to the study.Patrick Pleul/picture alliance via Getty Images People with COVID-19 may spew infectious particles that can spread beyond 6 feet, a study suggests. Cambridge University scientists used computer simulations to test scenarios of a person coughing. The study's authors urged people to keep wearing masks in indoor spaces such as offices and shops.

Infectious COVID-19 particles can spread beyond 2 meters when a person coughs, study suggests

Fish, seaweed inspire slippery surfaces for ships

Fish and seaweed secrete a layer of mucus to create a slippery surface, reducing their friction as they travel through water. A potential way to mimic this is by creating lubricant-infused surfaces covered with cavities. As the cavities are continuously filled with the lubricant, a layer is formed over the surface. In the journal Physics of Fluids, researchers in South Korea conducted simulations of this process to help explain the effects.
