The press release in the Metro has located Montpellier in Basque country. Which will be news to my neighbour who is a Montpelliérain. The original article says that David Lopez-Idiaquez , co- author, is at University of Basque. I guess if we want to know what was found out we’ll have to read the original article. Life’s too short for that, so I’m happy to read the press releases applying the usual cautions.
Especially METRO - only that they have fewer bad-news stories - I used to find METRO free on our bus.
