Japan has jumped out to an early lead over Cuba in the World Baseball Classic championship game. Why do I mention this? Not only have Japanese researchers made great contributions to evolutionary genetics, but the emperor of Japan has actually actively studied evolutionary biology. Also, the Japanese left fielder, Hitoshi Tamura, happens to share his name with the fairly prominent scientist, Koichiro Tamura. Every time I hear them refer to Tamura, I think about the Tamura-Nei distance correction.
