NORTH CAROLINA: Possible new approach to purifying drinking water - (Duke University)
June 3, 2008 – 11:11 pmDURHAM, N.C. - A genetic tool used by medical researchers may also be used in a novel approach to remove harmful microbes and viruses from drinking water.
In a series of proof-of-concept experiments, Duke University engineers demonstrated that short strands of genetic material could successfully target a matching portion of a gene in a common fungus found in water and make it stop working. 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.
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 […]
