Regulatory RNAs in prokaryotes: here, there and everywhere

P>A recent meeting on 'Regulatory RNAs in prokaryotes' reflected the growing interest in this research topic. Almost 200 scientists met to discuss the identification, structure, function and mechanistic details of regulatory RNAs in bacteria and archaea. The topics included small regulatory RNAs, riboswitches, RNA thermosensors and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) elements.
