Exposure to early life trauma can lead to poor physical and mental health in some individuals, which can be passed on to their children. Studies in mice show that at least some of the effects of stress can be transmitted to offspring via environmentally-induced changes in sperm miRNA levels. A new epigenetics study raises the
