Full disclosure: all of my colleagues refused to write a blog post on this topic.  “Ewww,” one said.  “I don’t feel comfortable writing about that,” said another.  Even when I pointed out that our department has written papers on very similar topics, they all declined.  So I decided to tackle it myself, because a) it’s a topic that applies to everyone who was ever born, b) is biologically very important and interesting, and c), I think it’s an excellent example of how the implications of a small but interesting scientific study can be misinterpreted, exaggerated, or distorted.
