SPOKANE, Wash. – Scientists have long tried to pin down the causes of autism spectrum disorder. Recent studies have expanded the search for genetic links from identifying genes toward epigenetics, the study of factors that control gene expression and looks at chemical modifications of DNA and the proteins associated with it. » More …

Toxic effects of mercury persists for generations

PULLMAN, Wash. – Zebrafish exposed to very low levels of methylmercury as embryos not only passed on toxic effects of the chemical exposure to their offspring, but also to the third generation, according to a study that investigated both epigenetic changes – chemical modifications to the DNA – and abnormal neuro-behavior associated with exposure. » More …
