My paper in graduate school that got the most attention was about Space Invaders. How do Space Invaders go along with Quantitative Biology, Genomics, and DNA in general? Here are a couple of links to explain. The first is a review that was done by National Geographic. The other is the link to the actual paper in PNAS.
Repeated horizontal transfer of a DNA transposon in mammals and other tetrapods, published in Proceeding of the National Academy of Science, October 2008.
