Results from a large population-based cohort study including 60,000 men and women in central Sweden suggest that exposure to higher concentrations of disinfection byproducts in drinking water is associated with elevated risk of colorectal cancer in men. Drinking water is a very important part of our diet that is consumed daily by essentially everyone in the population. Hence, assuring a that the public drinking water maintains a high standard is crucial. Chlorination of drinking water is a cheap and effective method widely used to control waterborne infectious disease. A drawback is, however, that reactive chemical byproducts can be formed in...

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. “Far-UVC light has the potential to be a ‘game changer,’” said David Brenner, professor of radiation biophysics and director of the center. “It can be...
