Finally, in this issue, Beach et al.(Beach, Lei, Brody, & Philibert, 2016) report an epigenetic study that begins to investigate how environmental interventions “get under the skin”. It asks, how do environmental manipulations change our biology to produce differential outcomes? The complexities inherent in analyzing epigenetic data are also discussed in Latendresse et al.’s methodological overview(Latendresse et al., 2017). Jointly, the papers in this special issue come together to produce a compelling overview of the state of the science with respect to the incorporation of genetic information into prevention studies, and illustrate the diversity of questions that can be addressed with the addition of genetically informative data into prevention science.
