B vitamins might play a role in reducing the impact of air pollution on the epigenome, a new study by researchers at Columbia University has shown. The study is the first to lay out a path of research for developing interventions to prevent or minimize the adverse effects of air pollution on potential automatic markers… Read more

Early life exposures to toxic chemicals such as PCBs and DDT dampen an infant’s response to the tuberculosis vaccine, according to a new study. The significance of the research extends far beyond TB vaccine responses and exposures to these two chemicals, says Todd Jusko, an assistant professor in the University of Rochester departments of environmental… Read more
