Researchers are probing the role that microRNAs, small noncoding bits of RNA, play in neurodegeneration in Drosophila melanogaster. The scientists genetically modified some flies to lack a particular microRNA called miR-210, which resulted in the degeneration of their photoreceptor cells and the flies going blind. They reported their results January 22 in Life Science Alliance.
