Hey R59, big thanks for alerting me to this one-- i might have missed it with all the projects i'm elsewhere involved in. Here's a link for a pdf file of the entire 11-page (dense, two-columns) article: https://www.gwern.net/docs/longevity/2019-decabo.pdf And there's a good brief overview of the article and lead researcher Mattson at https://www.sciencedaily.com/releases/2019/12/191226084351.htm (from John Hopkins Medicine newsletter).
