Every so often, some paper happens to grab my attention for various reasons. As I read the paper, often I have questions. Not all of those questions, unfortunately, can be easily submitted for answers. In recent times, one such paper was published earlier this month in PLOS One. The great benefit of the Open-Access model of PLOS is that it allows a reader to ask questions directly of the authors. This level of engagement is very laudable, especially to someone like me who has an interest in the communication of scientific facts.
