Far-UVC light safely kills ( or inactivate ) airborne coronaviruses

The researchers found that more than 99.9% of the exposed virus had been killed by a very low exposure to far-UVC light.

Based on their results, the researchers estimate that continuous exposure to far-UVC light at the current regulatory limit would kill 90% of airborne viruses in about 8 minutes, 95% in about 11 minutes, 99% in about 16 minutes, and 99.9% in about 25 minutes.

A grape constituent protects against Lung cancer

A team of scientists studied a well-known natural product, resveratrol, which is found in grapes and in red wine. While its chemopreventive properties against cancers affecting the digestive tract have been documented by previous studies, resveratrol has so far shown no effect on lung cancers. Thanks to nasal administration, the UNIGE team obtained very promising results in a study conducted in mice.
