Not 'Junk DNA' After All: Tiny RNAs Play Big Role Controlling Genes
http://www.sciencedaily.com/releases/2007/10/071025112059.htm

PiRNAs, a recently discovered class of tiny RNAs, play an important role in controlling gene function. Derived mostly from so-called "junk DNA," piRNAs had escaped the attention of generations of geneticists and molecular biologists until last year when Yale scientists discovered them in mammalian reproductive cells, and named them.
