Scientists Think They Can Extend Human Life by 25 Percent

Scientists from ETH Zurich in Switzerland and Jena University Hospital in Germany analyzed 40,000 genes in three different organism - roundworms, zebrafish and mice.The scientists looked for RNA molecules that - along with DNA - direct protein synthesis. Certain genes help move aging forward, and the idea is that by blocking some of these genes, their effect is stunted, and their lifespan extended.
