An RNA switch for stem cells
from Technology Review
Ribonucleic acid (RNA) molecules have long been known for their role in translating genes to proteins inside a cell, but more recently, scientists have found large numbers of RNA molecules that don't code for proteins but seem to have other cellular roles. Most research in mammals has focused on tiny RNA molecules called microRNAs, but a new study, published in Nature, describes the far-reaching effects of much larger and relatively unstudied RNA molecules called lincRNAs (short for large intergenic noncoding RNAs).
