The chemical signals that regulate our genome, known as epigenetic marks, are degraded over time, according to a study published in PNAS. Since these epigenetic lesions are reversible, drugs that increase life span could be developed.
A study by the University of Washington School of Medicine (USA) reveals that the ability of the human heart to adapt to physical exercise, stress and other factors is greater in people subjected to caloric restriction in their diet - that is, , a healthy diet but with 30% fewer calories than normal - for at least seven years.

And in 2050 there will be more over 65 than children under 14.
Some species of flatworms are capable of unlimited regeneration of their tissues to the point of being potentially immortal. A group of researchers from the University of Nottingham (United Kingdom) has studied the mechanisms by which these animals defy the passage of time.
Why do we grow old? Many scientists try to unravel the entire succession of processes that begin in the cell and lead to the progressive deterioration of tissues and organs. An article published in Science has found very long-lived proteins that could explain part of the mystery.
A few drops of ethanol, the substance in alcoholic beverages, can double the life expectancy of the small worm Caenorhabditis elegans, the most widely used animal model in aging studies, according to a new study from the University of California, Los Angeles published in PLoS ONE magazine.
