In this week's Science, a University of California, San Francisco-led team describes the use of a CRISPR-based technology to shed new light on the functions of long non-coding RNAs (lncRNAs). The approach, called CRISPR interference, allowed the researchers to study about 17,000 different lncRNAs in seven different human cell lines. By selectively inhibiting the expression of specific lncRNAs, they could globally search for their functions.
