So, maybe I'm just boring, but stories like http://www.theguardian.com/science/2014/mar/29/black-death-not-spread-rat-fleas-london-plague are fascinating to me. It kind of helps remind us that science isn't always infallible as some people act and that we can uncover things we previously misconceived.
Anyway, what do you guys think?
