If you heard NPR this weekend repeating the urban legend that cows have accents - that they sound different in different regions - you need to follow up with the very frustrated people over at Language Log, who have been smacking this down since 2006. (Embedded link to the 2006 refutation there.)
There is additional fun discussing how often BBC Science gets things wrong by sensationalising the stories. This wouldn't make them any worse than a thousand other news sources, except that they look down on so many others for sensationalised pseudo-science. Rather like the NYT. Though their formal science section usually seems good - it's the bad science in the other sections, all delivered with that raised nose and sniff.
