SCIENCE - Origins of genomic 'dark matter' discovered

A major milestone has been achieved in understanding genomic "dark matter" -- called non-coding RNA. This "dark matter" is difficult to detect and no one knows exactly what it is doing or why it is there in our genome, but scientists suspect it may be the source of inherited diseases. This research achievement may help to pinpoint exactly where complex-disease traits reside in the human genome ...
