The answer to this question is not yet known. So what happened in the following ten (!) years, have we finally figured out whether the effect is mediated by DNA methylation? Nah. Instead, they published an…
Until the recent ML-based announcement from Google (and maybe not even with that in hand), protein folding research went nowhere for at least 30 years. So I wouldn't be too critical of a 10 year gap.
Not too surprising that earliest experiences in life are going to color an individual's expectations of the world, and how to respond to it. "consequences on the epigenome" as the article so charmingly puts it.
