Author's Note: Is the DNA between genes really junk?

It only took me one neurobiologist to relearn everything I forgot about DNA after my freshman year of high school. But it turns out that I'm not the only one who's still figuring out DNA: Researchers recently found that it was that former ne'er-do-well junk DNA (and not any particular gene itself) that contained mutations that might lead to the development of melanomas.
