A Nerf war is an activity involving Nerf Blasters or other foam-firing toy weapons. Nerf wars can be a wide range of games, from informal shootouts in offices and basements to well-organized outdoor battles with high-powered modified blasters. Since foam-firing guns are relatively safe and cheap, Nerf wars can include participants and battlefields otherwise unsuitable for airsoft and paintball.
RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression, typically by causing the destruction of specific mRNA molecules. Historically, it was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling.NAi may be used for large-scale screens that systematically shut down each gene in the cell, which can help to identify the components necessary for a particular cellular process or an event such as cell division. The pathway is also used as a practical tool in biotechnology, medicine and insecticides.
