Organisms employ a fascinating array of strategies to identify and restrain invasive pieces of foreign DNA, such as those introduced by viruses. For example, many viruses produce double-stranded (ds)RNA during their life cycle and the RNA interference (RNAi) mechanism is thought to recognize...
Scientists studying a cunning parasite that has commandeered the cells of almost half the world's human population have begun to zero in on the molecular signals that must be severed to free the organism's cellular hostages. While Toxoplasma gondii is not as widely known by the public as some of...

Anti-sense reagents have been developed for C. elegans micro RNA. Researchers writing in BioMed Central's open access journal Silence have created the first class of reagents to potently and selectively inhibit miRNAs in this widely used model organism. Wen-hong Li, from the University of Texas...
