I'm a bit of a science geek and remember exactly where I was when I learned that the human genome project had been completed (La Quinta Hotel, Austin Tx for the record. I was killing a cricket the size of a rat when I heard the news). Sad, I know.
So, if your kid (or you) are into the genome project, you can get a FREE poster: Human Genome Landmarks: Selected Traits and Disorders Mapped to Chromosomes by clicking on the Genome Project web site and filling in their simple form. They also have a bunch of downloadable educational materials to keep brainy children quiet for an hour or two.
