Menopause: another possible reason

One of the most unpleasant and incomprehensible events in a woman's life — menopause — has received a new explanation. Scientists blame the stopping of the "birthing mechanism" of daughters-in-law who fought for power in a primitive family.

Sirtuins are a target for old age pills

The ancient and universal mechanism of aging is based on the weakening of the ability of sirtuin enzymes to simultaneously perform both their functions – both to repair DNA damage and to regulate gene activity. Hopefully, the substances that activate the synthesis of sirtuins that are being tested on animals can slow down the aging process in humans as well.

Biological age can be determined by the activity of genes

Calculating biological age is not an easy task. Now it is possible to measure aging by the activity of certain genes, but so far only in roundworms – the favorite of geneticists Caenorhabditis elegans.

Old people! Don't be afraid of sex!

Now a person aged 65 can safely expect to live another two decades or so. Naturally, many people want to make up for those hours of sex that were "lost" earlier due to stressful work, crying children or fears of getting pregnant.

Anti-Aging Science

Russia has developed a global scientific program to combat aging, which can become the basis of a national strategy for life extension.

To live for a long time, you need to study well, son!

According to the degree of influence on mortality (regardless of whether this influence is direct or indirect), IQ and "reliability" turned out to be almost as significant factors as a combination of smoking, high cholesterol and high blood pressure.

Something happened to my memory…

Often, especially from elderly people, you can hear: "I forgot again. Damn sclerosis!" Those who are younger usually say this in jest. Older people tend to be concerned about their forgetfulness. Is memory deterioration an inevitable process?

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.

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.

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.

Where can I get a pill for old age?

At the VIII International Symposium "Biological Mechanisms of Aging", scientists analyzed the results of research on the mechanisms of aging of various biological systems, discussed new theories in this field and the features of new experimental approaches, as well as social aspects of gerontology.

Psychologists believe that in old age a person really becomes wiser

If the accumulated information is knowledge, and wisdom is the ability to organize this knowledge and use it, then of course old age is associated with wisdom. But over the years, wisdom does not always come: it is inherent only in the aging brain, not pathologically, due to diseases, but naturally.

Seminar "Genetics of life expectancy and aging": personal impressions

On March 25-26, 2008, the first All-Russian seminar "Genetics of life Expectancy and aging" was held at the Institute of Biology of the Komi National Research Center of the Ural Branch of the Russian Academy of Sciences (Syktyvkar).

Why are the old women alive

Scientists have found strong evidence against the "grandmother hypothesis", which explains why women continue to live after menopause. The "hypothesis of motherhood", which explains both long life and menopause itself, received support.

Hot spots of modern gerontology

The increase in life expectancy and the aging of the population of developed countries have increased interest in gerontology, and above all, in the study of the primary mechanisms of aging of organisms and populations, as well as factors determining life expectancy.

To live to be a hundred years old is easier than you thought

The contribution of genes to life expectancy is only 25%, and the chances of changing the second hundred are not only in relatively healthy people, but also in patients with various chronic diseases.
