For John, BLUF: Beware of "settled science". Nothing to see here; just move along.
From the pages of The New York Times we have a review of a new book on science.
Madness and Memory:The Discovery of Prions--A New Biological Principle of DiseaseSometimes it appears that scientific advancement is not a minuet of after you, no after you, but rather guerrilla warfare, with little skirmishes continuing even after the Nobel Prize has been bestowed.
Stanley B. Prusiner (Author), David L. Michelmore (Editor)
Sweet revenge comes in many delectable forms, among them the receipt of accolades for work long scorned. And then to get to tell the whole story at length and without a single interruption — small wonder that the Nobel laureate Dr. Stanley B. Prusiner, a renowned neurologist at the University of California, San Francisco, writes with a cheerful bounce. Once disparaged, his scientific work is now hailed as visionary, and his memoir takes the reader on a leisurely and immensely readable victory lap from then to now.Regards — Cliff
