'Tis the season when media feels obligated to publish Top 10 lists ranking the year's cultural moments.

It is also, apparently, a chance for the science press to take one more kick at Portland for that fluoridation vote.

Real Clear Science, a national lab-rat news aggregator owned by Forbes, has released its list of the 10 events it dubs "The Biggest Junk Science of 2013."
