Epigenetics describes modifications to the genome that can be passed on to future cells.These changes do not alter the nucleotide sequence of the DNA-the As, Gs, Ts, and Cs that make up our genes. Rather, they modify the "backbone" that supports the DNA sequence. These modifications influence when and how often a gene is active. Credit: Darryl Leja, NHGRI.

Some time ago I wrote a blog post with Aleksandra Stelmach and Alan Miguel Valdez  about visuals used to make epigenetics public through the popular lens of transgenerational epigenetic inheritance. I then promised some image analysis. Here is a summary of what we found (I thank ChatGPT for helping me summarise our findings. If you want references, …

Making the transgenerational epigenetic inheritance of trauma real

August 2, 2019

This post has been co-authored with Aleksandra Stelmach and Alan Miguel Valdez *** Transgenerational epigenetic inheritance (TEI) is a contested hypothesis within the complex field of epigenetics. The guess is that there are molecular mechanisms (‘beyond the gene’) through which social, cultural and physical experiences impact the human body and are transmitted to future generations. …

I thought I had written my last post about epigenetics. But then came along some ‘worms’ and I had to write another one. I have written about worms once before on the Making Science Public blog, in the context of science communication. And this blog post too will reflect on worms in the context of …
