09.11.2011Selective stimulation of the dPGC-1 gene activity in drosophila intestinal stem cells improved the health of insects and significantly increased their life expectancy.
07.11.2011Differences in the state of the immune system will make it possible to identify people who have every chance of maintaining good health and a clear mind until old age, as well as those who need timely prevention of age-related diseases.

20.09.2011Many symptoms of aging, such as shaking hands, balance disorders, difficulty walking, etc., can be caused by blockage of the smallest vessels of the brain, which cannot be detected using existing methods.
02.09.2011The reason for the increase in bone fragility as we age lies not only in the decrease in bone mass, leading to osteoporosis. Aging leads to deterioration of the mechanical properties of the cortical substance (outer layer) of the bone at different structural levels.
31.08.2011High levels of cathepsin S in the blood of elderly people indicate an increased risk of death from cancer or cardiovascular diseases.
30.08.2011Researchers from Yale claim that free radicals make us overeat – one of the causes of aging. A disappointing alternative: be young and fat or aging fast, but with a great figure…
29.08.2011Over the past ten years, people from the low-income group have shortened telomeric sections of chromosomes on average by an order of magnitude more than their wealthier compatriots.
29.07.2011With senile dementia, a person pays for the years lived after the loss of reproductive abilities. In monkeys, fertility persists until the end of life, and their brains degrade much less in old age than in humans.
26.07.2011The absence of type 1 cannabinoid receptors (CB1) is associated with the rapid development of symptoms of brain degeneration similar to those observed in patients with senile dementia.
14.07.2011Experts have long suspected the existence of a relationship between chronic stress and neurodegenerative diseases, but its molecular mechanisms remained a mystery. One of these mechanisms has recently been discovered.
01.07.2011Rapamycin not only increases the lifespan of mice, but also reverses the premature aging of human cells with progeria – unfortunately, so far only in vitro.
30.06.2011Shortening of telomeres triggers the synthesis of progerin in the cells of a healthy body – a toxic protein that causes premature aging in people with the hereditary disease progeria.
15.06.2011It has long been known that the suppression of the mTOR signaling pathway prolongs the life of various types of living organisms, from unicellular to mice. It turned out that this enzyme can be inhibited by targeted exposure to reactive oxygen species.
09.06.2011Nobel laureate Elizabeth Blackburn – about the incorrect statements of the media about the recently developed test for determining the length of telomeres and the importance of such testing for doctors and their patients.
31.05.2011When comparing the DNA of orphaned children who grew up in an orphanage or foster families, it turned out that the telomeres, the chromosomal clock that determines the life of a cell, shorten faster in the former.
18.05.2011Scientists studying the relationship between nutrition and longevity have found new evidence that a low-calorie diet helps people live longer: significant calorie restriction leads to a decrease in central body temperature.
16.05.2011Suppression of the synthesis of mitochondrial translational control proteins necessary for normal biosynthesis in these organelles led to prolongation of cell life.
11.05.2011A sharp disruption of the BAF-1 protein in all cells of the body leads to progeria, but during a person's life, many mutational changes in the BAF-1 gene can accumulate, which leads to the same aging. Only delayed and stretched in time.
