Old age on schedule: when and how do our organs change their work?

In childhood and youth, our body grows and develops, then exists, as they say, according to a rolled-up scheme, and then begins to age gradually. It turns out that different organs begin to age at different times.

About the benefits of smoking

According to scientists, smoking "strengthens memory and the ability to concentrate."

Ordered to live a long time

Comparing the mortality charts of human populations in different regions of the world and calculating them according to a special program, the researchers got the result: 95 years. It is this age that corresponds to the specific duration of human life.

Cloning benefits a person

From a practical point of view, human cloning has two purposes. The first is reproductive cloning to produce offspring. Especially acute issues of reproductive cloning affect infertile people, as well as people of non-standard sexual orientation who are unable or unwilling to have children sexually. The second purpose is therapeutic cloning, obtaining embryonic stem cells, for the treatment of diseases.

Dr. Watson's visit

The legendary James Dewey Watson, the one who, together with Francis Crick, proposed a model of the DNA molecule in the form of a double helix, came to Moscow at the invitation of the Russian Academy of Sciences, and his lecture at the House of Scientists on Prechistenka was organized by the Dynasty Foundation.

Prolonging youth

Aubrey de Grey claims that the average life expectancy of people in developed countries will soon grow to a thousand or more years, and by 2100 to 5000.

Laminopathies and the aging process

The problem of genetic control of life expectancy and the aging process has many facets, one of them was highlighted in the study of hereditary diseases included in the group of laminopathies.

Histocompatibility system genes and longevity

The study of genetic markers of aging and age-related diseases is one of the most relevant areas in gerontology.

Age-related changes in nonspecific immunity - prolonging life

Numerous facts indicate a decrease in the effectiveness of the functioning of the immune system with increasing age, as a result of which the incidence and mortality from infectious diseases increases tens and hundreds of times. The weakening and violation of the immune response is associated with an increase in the frequency of oncological and autoimmune diseases.

The main scientific theories of aging

The mechanisms of aging are quite complex and diverse. Today there are several alternative theories that partly contradict each other, and partly complement each other.

Old and new theories of aging

There are several dozen theories of aging. Many of them are already only of historical interest, while the rest, reflecting a number of essential aspects of the process, can be put into a logical scheme of a more universal general mechanism of aging. One thing is common to all hypotheses – the aging of the body begins immediately after the division of the fertilized egg begins.
