Bacteria employ many different strategies to regulate gene expression in response to fluctuating, often stressful, conditions in their environments. One type of regulation involves non-coding RNA molecules called small RNAs (sRNAs), which are found in all domains of life. A new study led by researchers at the University of Illinois describes, for the first time, the impacts of sRNA interactions in individual bacterial cells. Their findings are reported in the journal
