Scientists may have discovered the fountain of youth, a study reveals.

Researchers found they could prolong the lives of mice by genetic manipulation, which mimics the health benefits of a low-calorie diet, Agence France-Presse reported.

The study suggested that age-related diseases can be easily treated.

Researchers from Institute of Healthy Ageing at University College London were able to genetically manipulate mice so that they blocked the production of the S6 Kinease 1 protein, otherwise known as S6K1. This reduced the number of age-related diseases affecting mice and extended their lives by a fifth.

S6K1 is involved in the body’s response to changes in food intake, so by blocking the protein, the mice did not actually have to reduce the amount of food they ate, according to the study that is published in the journal “Science.”

The scientists said the mice had stronger bones, were leaner and were protected from Type 2 diabetes. They also performed better at motor tasks, and had better cognition.
