Free energy lights the path toward more effective RNAi

Silencing gene expression by RNA interference (RNAi) has become a daily activity for mammalian cell biologists. Those who often use this approach have come to appreciate its occasional frustrations and potential limitations. A pair of recent papers in Cell provides rules for designing short interfering RNAs (siRNAs) that are both validated at the practical level and understood mechanistically.
