Fans of science, trivia and wine (and I’m guessing there are a few of you on here) should mark 27 July in their diaries now. The second science pub quiz at the Royal Institution begins around 7pm and will be co-hosted by Martin Davies of the RI and myself. Nature Network superstars bloggers Richard Grant and Jenny Rohn have set a special ‘guest round’ of questions. Entry is £2 per person with teams of up to five. Meanwhile, a few photos from the last quiz’s picture round still need de-puzzling.
