I know what an Emeritus Professor is Iains, I am one myself. I do not begrudge McGuire his right to write columns in the media, but if I were to do so myself I would not stray beyond work which had already withstood peer review. Now he may not have done so, it isn't possible always to access the full text of the peer reviewed papers, but what concerns me most is the time lapse between those papers and the newspaper articles.
