Study finds electronic cigarettes damage brain stem cells

A research team at the University of California, Riverside, has found that electronic cigarettes, often targeted to youth and pregnant women, produce a stress response in neural stem cells, which are critical cells in the brain. Present throughout life, stem cells become specialized cells with more specific functions, such as brain cells, blood cells, or […]

Scientists have reported that many inheritance mutations are caused by DNA damage rather than errors in DNA doubling. The study was conducted by an international research group and published in Nature Genetics. Unfortunately, the reasons for mutations in normal cells that have not been exposed to ultraviolet, smoke or other external mutagens are understudied. According […]
