Very nice piece of science reporting. And really, what you would expect from the publishing outlet of such a vaunted institution. Reads quite a bit like listening in to a conversation among the scientists and researchers cited. Excellent quoting, commentary, sourcing, and running commentary by the Author. The included graphic is a plus and helps in providing context and a visual point of reference. The links provide for further reading and are definitely worth a look-see. This is the type of science write-up that one would think interests nearly everyone. We all have memories. Although, things do get a bit fuzzy the morning after a few drams of single malt the night before. A worthwhile read and investment of time. Four point five stars!
