A study from the National Institutes of Health claimed that permanent hair dye and chemical hair straighteners could increase the risk of breast cancer among women. The study published online on Dec. 4 in the International Journal of Cancer found that women who used permanent hair dye and chemical hair straighteners were 9% more likely to develop breast cancer than those who did not. The NIH used a sample size of 46,709 women. Researchers stressed that there was little to no increase in breast cancer risk for semi-permanent or temporary dye use."Researchers have been studying the possible link between hair dye and cancer for a long time, but results have been inconsistent," said corresponding author Alexandra White, Ph.D., head of the NIEHS Environment and Cancer Epidemiology Group. "In our study, we see a higher breast cancer risk associated with hair dye use, and the effect is stronger in African American women, particularly those who are frequent users. "While the study suggests an increased risk for women, these results need to be replicated in other studies to make a conclusion, the NIH said. When asked if women should stop dyeing or straightening their hair, co-author Dale Sandler, Ph.D., chief of the NIEHS Epidemiology Branch, said, "We are exposed to many things that could potentially contribute to breast cancer, and it is unlikely that any single factor explains a woman’s risk. While it is too early to make a firm recommendation, avoiding these chemicals might be one more thing women can do to reduce their risk of breast cancer." 1576

After weeks of relatively warm conditions for much of the Midwest and Northeast, a major snow storm has the Midwest and Northeast in its sights. Blizzard warnings have been issued for parts of the Dakotas, Minnesota, Iowa and Nebraska. Winter storm warnings are in effect for parts of Iowa, Illinois, Minnesota, Wisconsin, Michigan, New York, New Hampshire, Connecticut, and Massachusetts.

Several campaign events have been canceled ahead of the storm. Joe Biden and Pete Buttigieg have canceled events scheduled for Iowa.The storm is expected to drop 4 to 8 inches in a large swath from Nebraska to Maine. Some areas could also see freezing rain.

Air bags are an essential safety feature in modern vehicles, but for some drivers and passengers, air bags aren't providing a satisfactory level of safety, according to a government agency.The National Highway Traffic Safety Administration announced recently that 10 million additional air bags have been added to a recall of Takata air bags. The air bags were installed by 14 different automakers, including some Ford, GM and Toyota models. The NHTSA said that exposure to long-term heat and humidity can cause these air bags to explode when deployed. The NHTSA claims that faulty air bags have caused injuries and fatalities. "The propellant in some of the subject inflators may degrade over time, which could lead to over-aggressive combustion in the event the air bag is activated," the NHTSA said. "Overly aggressive combustion creates excessive internal pressure when the inflator is activated, which may cause the inflator body to rupture."To find out if your vehicle has been recalled, click 1012
