A recent article in The Economist (June 16, 2007) describes research on RNA as the 21st centurys Big Bang in biology. The "stars" of the RNA universe are small regulatory RNAs known as microRNAs (miRNAs). These
22-nt-long RNAs were discovered in 1993 (Lee et al. 1993
; Wightman et al. 1993
), but their role in biology remained obscure until 2001, when the Tuschl, Ambros, and Bartel laboratories identified hundreds of miRNAs in different organisms (Lagos-Quintana et al. 2001
; Lau et al. 2001
; Lee and Ambros 2001
). Functional analyses of these miRNAs and their associated complexes subsequently
