Scientists are continuously striving to find ways to satiate urge of human beings to retain youth forever. Recent study has once again given hope to find way to look young forever. The study showed that by blocking production of a specific gene imitating low calorie intake could extend life span and decreased vulnerability to age-related diseases in mice.

Various studies have already shown health benefits of intake of low-calorie diet. In the recent study by removing or blocking ribosomal S6 protein kinase 1 (S6K1) gene mice lived 20 percent longer on average. S6K1 gene is related to body's response to changes in food intake. Triggering off this gene had similar effect as reducing the number of calories diet.

Dominic Withers of the Center for Diabetes and Endocrinology at University College London said: "These mice were resistant to type 2 diabetes ... and they also appeared to have reduced incidence of the mouse-equivalent of osteoporosis -- so they had stronger bones."

Study also showed that T-cells which is a key component of the immune system was also found "youthful,'' in the mice involved in the study.
