The researchers tested the film for anti-viral activity using four different viruses two strains of influenza A virus, a highly-stable picornavirus called EMCV and SARS-CoV-2.
They exposed the film to either UVA radiation or with light from a cool white light fluorescent lamp.

https://www.afinalwarning.com/508945.html (Natural News) Researchers found that sunlight inactivates the Wuhan coronavirus (COVID-19) more than eight times more quickly than predicted. Paolo Luzzatto-Fegiz, a professor of mechanical engineering at the
University of California, Santa Barbara (UC Santa Barbara), and his colleagues reviewed recent studies that explored the effects of different bands of ultraviolet (UV) light – namely, UVA, UVB and UVC radiation – on SARS-CoV-2, the virus behind COVID-19.
UVA is weakest among the three while UVC is the most energetic and has been shown to inactivate viruses such as SARS-CoV-2. Nearly all of the UV radiation that reaches the surface is UVA since all of UVC and most of UVB rays are absorbed by Earth’s ozone layer.
they keep failing. all right, karen travers, thank you. the bailout of general motors has cost american taxpayers more than $11 billion, a billion more than initially estimated. that loss includes more than $800 million the u.s. treasury wrote off last month ending its involvement with gm. the bush and obama administrations collectively distributed $50 billion in emergency aid to gm to help that company survive the economic crisis. the dow is opening in record territory this morning. stocks closed at an all-time high yesterday. hitting 16,580, slightly topping the number set in november. the federal reserve said it would reduce the bond-buying programs but plans to keep the benchmark interest rate at near zero. topping the health headlines this morning, a warning about the uv lights used in the popular gel manicures. researchers looked at 17 ultraviolet lamps from commercial nail salons and tested them for uva radiation, a type of light known to cause dna damage. they found tha
from the age old curse known as wrinkles. photo aging comes from exposure to the sun s radiation, and specifically uva radiation. it s not the uvb radiation has linked to cancer. you can see it in these photos. this is the hand of a person with no skin damage, and this is someone with severe photo aging. in a study with 900 patients, those who used sunscreen daily over a 4 1/2 year period were 24% less likely to see these kinds of progressive changes. and doctors say this message will resonate with their patients. every patient, we try to tell them to use sunscreen, and believe it or not, just the message of preventing skin cancer doesn t always get through to people. so i m hoping that maybe vanity will weigh out in this case. the rules for sunscreen, she says, are simple. you want to look for an spf of about 30. you want it to be broad spectrum, which means it covers
