Scientists have taken a big step toward developing therapies based on naturally occurring tiny RNA molecules called microRNAs. In the first successful experiment with primates, researchers have blocked microRNAs to lower cholesterol levels in monkeys. This achievement builds hope that the strategy could one day be used to attack human diseases. Safety concerns still linger, however.
