Mick O’Hare wears one hat as production editor for New Scientist and another as editor of The Last Word column of questions and answers at the back of the magazine. Mick joined New Scientist 14 years ago after being the production editor for Autosport. Because you can take the boy out of the north but you can’t take the north out of the boy, he freelances as a rugby league writer and also edits sports books. More importantly he is a lifelong supporter of Huddersfield Rugby League Club. He has a geology degree but retains a healthy disregard for crystallography.
