RNA

MIT researchers have discovered that a bacterium found in the human mouth can be used to form a new CRISPR gene-editing system that can target RNA, reports Carl Zimmer for The New York Times. The development “may open up a new front in gene engineering, gaining the ability to precisely adjust the proteins in cells, for instance, or to target cancer cells." 

New Scientist reporter Colin Barras writes that MIT researchers have found they can program C2c2, an enzyme found in bacteria, to serve as an RNA-editing tool. Barras writes that the tool “promises to transform our understanding of RNA’s role in our growth and development, and provide a new avenue for treating infectious diseases and cancer.”
