Scientists discover new class of small RNAs

Researchers at Cold Spring Harbor Laboratory (CSHL) announced today the discovery of a new class of small RNAs. At the same time, they reported that their discovery suggests the presence of a strikingly novel biochemical pathway for RNA processing in which these and possibly other small RNAs are produced.
