Why can't we stay young forever

Researchers stop the aging process - will we stay young forever?

US scientists claim to have developed a method that reverses the aging process. The treatment has already been successful in nine participants in a small study.

Last Friday, during the conference of the Life Extension Advocacy Foundation (Leaf) in New York, the lecture entitled "Reversing Human Aging Right Now!" listened, must have rubbed his eyes in amazement.

Gregory "Greg" Fahy of the biopharmaceutical company Intervene Immune said the unbelievable: his team had succeeded in reversing the biological age of nine male study participants.

Within a treatment or observation period of only 12 months, the biological clock of men between 51 and 65 years of age was turned back by about two and a half years. An already graying man involved in the experiment confirmed to “Zeit Online” that dark hair had grown back again.

Fountain of youth for the thymus gland

Originally, the researchers were only interested in finding a therapy to treat age-related ailments. The thymus gland was at the center of scientific interest. This organ trains the body's immune cells and slowly atrophies from the age of 30. In order to stimulate the production of the gland again, the researchers relied on a mix of the hormones hGH and DHEA as well as the diabetes drug metformin.

Imaging (magnetic resonance tomography) already showed during the study that the thymus gland increased in volume. The blood values ​​of the test subjects also showed that a rejuvenating process had been set in motion. The researchers suspect that the treatment reactivated a biological program that allowed the thymus to grow at the beginning of life.

For the first time it was possible to turn back the clock of human life, explained Greg Fahy. Whether and to what extent the results of the scientist and his colleagues will lead to the development of effective anti-aging therapies cannot yet be foreseen. Can the results of the small, uncontrolled observational study be confirmed in the context of large-scale studies? Does treatment with the hormone-drug cocktail produce severe, perhaps even life-threatening side effects in the long term?

Until these questions are resolved and an effective antiaging drug hits the market, there is only one option left: to slow down the aging process through a healthy lifestyle.

Scientists at ETH Zurich recently simulated that due to global warming at the end of the century, there are probably only a few small ice fields left of the glacier, which is currently over 80 square kilometers.
