The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers at the University of California San Diego studied these ultraviolet (UV) light emitting devices, and found that their use leads to cell death and cancer-causing mutations in human cells. The devices are […]
Killing coronavirus with handheld ultraviolet light device may be feasible
A personal, handheld device emitting high-intensity ultraviolet light to disinfect areas by killing the novel coronavirus is now feasible, according to researchers at Penn State, the University of Minnesota and two Japanese universities. There are two commonly employed methods to sanitize and disinfect areas from bacteria and viruses — chemicals or ultraviolet radiation exposure. The […]
Eating Habits Affect Skin’s Protection Against Sun
Sunbathers may want to avoid midnight snacks before catching some rays. A study in mice from the O’Donnell Brain Institute and UC Irvine shows that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun’s harmful ultraviolet radiation. Although further research is […]
Harmful effects of CFL bulbs to skin; Energy-efficient bulbs safest when placed behind additional glass cover
Researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs. Results revealed significant levels of UVC and UVA, which appeared to originate from cracks in the phosphor coatings, present in all CFL bulbs studied. Inspired by a European study, a […]
