Blogged from www.sciencedaily.com A genetic tool used by medical researchers may also be used in a novel approach to remove harmful microbes and viruses from drinking water. The relatively new technology, known as RNA interference (RNAi), makes use of short snippets of genetic material that match — like a lock and key — a corresponding segment of a gene in the target. When these snippets enter a cell and attach to the corresponding segment, they can inhibit or block the action of the target gene. This approach is increasingly being used as a tool in biomedical research, but has not previously been applied to environmental issues. If this new approach can be perfected, the researchers believe that it could serve as the basis for a device to help solve the problem of safe drinking water in Third World countries without water treatment facilities.
