Sorry for the delay! I have been busy with work and the holidays but, continuing from the last episode, this episode discusses recent advances in the field of epigenetics. I discuss how the field has changed since its coining, how epigenetics interacts with the environment, and how diseases affect gene expression. There are myriad ways in which gene expression can be altered and we talk about a few here, including methylation and histone modification. The full citation for this paper is: Cavalli, G., and Heard, E. Advances in epigenetics link genetics to the environment and disease. Nature 571, 489-495 (2019). DOI: 10.1038/s41586-019-1411-0. 

As always if you have any questions, comments, or concerns, or you have a paper you'd like me to review, send the full citation to podsauce@gmail.com! Thanks for listening.
