Nicely done. Very good science reporting. It is worth noting that the Author's style here gives one the impression that she enjoys the craft of writing. Good sourcing, with the full study referenced available for review. I scanned it quickly and it is definitely worth a look for the sake of further context. Breezily written in an engaging manner which makes for not only informative reporting but interesting reading as well. The historical references are splendid and most welcome. Additionally, they lend a mildly humorous atmosphere to an otherwise caliginous subject matter. A good use of one's time and intellectual energy. Four stars!
