A new type of ultraviolet light that is safe for people took less than five minutes to reduce the level of indoor airborne microbes by more than 98%, a joint study has found. Even as microbes continued to be sprayed into the room, the level remained very low as long as the lights were on. The study suggests that far-UVC light from lamps installed in the ceiling could be a highly effective passive technology for reducing person-to-person transmission of airborne-mediated diseases such as COVID and influenza indoors, and lowering the risk of the next pandemic. "Far-UVC rapidly reduces the amount...

The methodology behind the Maricopa election audit has been kept under wraps, but video of the audit appears to show the technique that many had hoped to see. When inventor Jovan Pulitzer testified in Georgia that he could detect fraudulent ballots by scanning them and running them through a high-tech analysis that included pattern recognition algorithms, many who believe the 2020 election was stolen started calling for this process to be widely applied in audits. But the price tag was high and legal roadblocks have slowed or stopped most attempted forensic audits from happening. Maricopa County in Arizona is one...

As if the winter darkness doesn't present its own health challenges in a non-pandemic year, a recent study suggests that the sun's lack of intensity in the coldest months of this year might also be enhancing the transmission of COVID-19. However, that also means good news may be on the horizon, literally, as an increase in sunlight could shine hope in the battle against coronavirus transmission. -SNIP- A recent study published by the Proceedings of the National Academy of Sciences found that UV light has a particularly significant effect on the spread of SARS-CoV-2, the virus that causes COVID-19. -SNIP-...

About two or three weeks ago I was thinking about all the absurd regulations in place to reopen businesses. In my thinking I came up with a idea that might work very well. Back in March I had to put in new HVAC unit for my upstairs, I had put in a a new downstairs unit in four years earlier. Well the HVAC guy told me that included with my new unit was a UV Light Filtering system. Since I am downstairs more than up I had him put UV system on the downstairs unit. According to the HVAC guy...

A technique that zaps airborne viruses with a narrow-wavelength band of UV light shows promise for curtailing the person-to-person spread of COVID-19 in indoor public places. The technology, developed by Columbia University’s Center for Radiological Research, uses lamps that emit continuous, low doses of a particular wavelength of ultraviolent light, known as far-UVC, which can kill viruses and bacteria without harming human skin, eyes and other tissues, as is the problem with conventional UV light.

Public spaces such as subways, suburban trains, schools, or waiting rooms are breading grounds for germs that - especially in the fall and winter - contribute enormously to the spread of influenza and other types of viruses. Like many other illnesses, the flu is transmitted via droplet infections. That is, when talking, coughing, and sneezing infected individuals spray tiny droplets into common airspace, putting those around them at risk. For a long time, scientists have been looking for ways to keep the air in public spaces "germ-free" - without endangering people with harmful chemicals. Researchers at the University of Columbia...

UV light-enhanced tooth bleaching is not only a con, but is dangerous to your eyes and skin, says a Royal Society of Chemistry journal. The light treatment gives absolutely no benefit over bleaching without UV, and damages skin and eyes up to four times as much as sunbathing, reports a study in Photochemical & Photobiological Sciences. Those looking to match Tom Cruise's glittering pearly-whites would be better off ignoring claims of better bleaching with UV light treatment.

If you yelled for 8 years, 7 months and 6 days you would have produced enough sound energy to heat one cup of coffee. (Hardly seems worth it.) If you farted consistently for 6 years and 9 months, enough gas is produced to create the energy of an atomic bomb. (Now that's more like it!) The human heart creates enough pressure when it pumps out to the body to squirt blood 30 feet. (O.M.G.!) A pig's orgasm lasts 30 minutes. (In my next life, I want to be a pig.) A cockroach will live nine days without its head before...

COLUMBIA, Tenn. — A malfunctioning light bulb in an elementary school gym exposed more than 100 people to short-wave radiation for an hour, sending 18 to the hospital with severe sunburns and swollen eyes. The incident occurred during a 9/11 memorial service held Friday afternoon at the Baker Elementary School in Columbia. Attendees, many of whom were veterans, said that they started to feel symptoms soon after the event began. "While I was sitting in the auditorium, my forehead started itching real bad," said Fred Young, 73. "When I got home I looked into the mirror and my face looked...

Bernie Goldberg on O'Reilly said MSM is now "Old Media"!! No longer mainstream,as we all know. I like it!

Meanwhile, the Sun itself has not been just sinking quietly below the horizon. For example on May 2nd, two enormous clouds of energetic particles blasted away from the...

The above image shows, however, that even during off days the Sun's surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius. Large sunspot group AR 9169 is visible as the bright area near the horizon. The...
