Experiments testing the ability of ultraviolet light to stop the spread of a costly virus for pork producers has shown promise, according to an ISU research team. Ultraviolet light analyzed in experiments irradiates aerosolized droplets of the virus that causes porcine reproductive and respiratory syndrome. The researchers hope to scale their experiments up to a size comparable to pork production facilities.
The finding could lead to new ways to prevent cold sores and herpes-related eye disease from reoccurring, the researchers report.
Johns Hopkins Medicine, together with 100 of the nation’s other top health care systems, representing thousands of hospitals in communities across the U.S., have come together with an urgent plea for all Americans: mask up, because wearing a face mask is one of the best ways to slow the surging COVID-19 pandemic.
University of Delaware researchers, led by biomedical engineer Jason Gleghorn, have devised a system for decontaminating N95 masks using off-the-shelf materials that can be purchased at a hardware store for about $50, combined with ultraviolet type C (UV-C) lights found in academic research and industrial facilities.
The American Academy of Dermatology has named board-certified dermatologist Iltefat H. Hamzavi, MD, FAAD, a Patient Care Hero for his innovative use of light therapy to sanitize masks needed by frontline health care workers.
Robots fitted with ultraviolet light lamps that roam vineyards at night are proving effective at killing powdery mildew, a devastating pathogen for many crops, including grapes.
The idea of UV sterilization is not a new one, but little or no scientific data about its potency against COVID-19 have been collected, until now. Thanks to a one-year, $182,728 grant from the National Science Foundation, researchers at Binghamton University, State University of New York are beginning to test UV’s effectiveness.
Upon exposure to human skin, ultraviolet light from the sun almost instantly generates two types of “lesions” that damage DNA. Scientists at UW Medicine in Seattle determined which of these lesions is responsible for activating a process that may increase cancerous mutations in cells.
Despite PPE use, reports show that many health care workers contracted COVID-19. A novel training technique reinforces the importance of using proper procedures to put on and take off PPE when caring for patients during the pandemic. Researchers vividly demonstrate how aerosol-generating procedures can lead to exposure of the contagion with improper PPE use. The most common error made by the health care workers was contaminating the face or forearms during PPE removal.
Engineers at Binghamton University, State University of New York have designed sterilization stations that use ultraviolet light to kill the coronavirus on any contaminated personal protective equipment (PPE) such as N95 masks and face shields.
Berkeley Lab scientists have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.
In the perennial clash between man and microbe, ultraviolet light has emerged as one of man’s powerful tools against many pathogens. Although ultraviolet light can wipe out several germs, the exact mechanisms that orchestrate the radiation’s damaging action have long been elusive. Texas A&M scientists can now explain how it works
