Question and answer

Question-and-answer articles in BMC Biology provide an easily digestible and often lively guide to topics of current interest or fundamental importance. Some are pedagogic (for example, on epistasis or cooperativity), some question the meaning of widely used terms (biodiversity, pathogenicity), some are both topical and pedagogic (on fructose toxicity, or on what we have learned from the 2010-2011 influenza pandemic), some are topical, pedagogic and quirky (on the definition of life); and the video and audio Q&As (with edited transcripts) represent the point of view of prominent individuals.
