The role of mitochondria in cell aging

An international group of scientists has managed to decipher the mechanism by which mitochondria contribute to cell aging. One of the main factors of senescence is the process of formation of new mitochondria.

Sleep and Aging II

Sleep disorders are almost always manifestations of some painful processes in the body. At the same time, a number of diseases that are often observed with sleep problems are also detected in the elderly.

Sleep and Aging I

Although aging of the body is not a periodic process, its course directly depends on the biorhythms of a person, in particular, on the sleep and wakefulness cycle.

Breakthrough in understanding the mechanisms of skin aging

The manifestations of skin aging are caused by a decrease in the bioenergetics of fibroblasts due to the extinction of the activity of an enzyme known as mitochondrial complex II.

The effect of stress on telomere length has been questioned

The largest meta-analysis to date has found a practical lack of connection (and even a negative, albeit weak, correlation) between stress and telomere length.

A new factor for cancer prediction

If a person's biological age exceeds his chronological age, this may mean a significant increase in the risk of developing cancer and subsequent death from it.

Fat people live longer than skinny ones

Yeast cells with a large amount of fat deposits live longer than "thin" ones, which confirms the so-called obesity paradox, according to which the mortality rate from all causes for overweight people is lower than for slim ones.

Overcome aging. Part II.

Some burrowing ("underground") rodents belonging to the families Spalacidae (blind man) and Bathyergidae (Damar digger and naked digger) are famous for their long life for their weight category.

Speed up and slow down the time for the worm

Experiments with mutant worms living in different conditions have shown that the survival curve can lengthen or shorten depending on heredity and external factors, but its shape almost always remains unchanged.

Overcome aging. Part I.

In this article we will talk about animals for which the insignificant (negligible) mode is shown or only assumed and a little bit about original approaches to achieving negligible aging in humans.

Aging trajectories

The dynamics of aging is traditionally described with the help of "survival curves", showing what proportion of individuals survive to a certain age. The nature of the dependence of mortality on age varies greatly among different organisms.

Phytotherapeutic geroprotector

Scientists from Japan have found out that the folk drug rikkunsito, used for stomach pains, causes the body to produce the hunger hormone ghrelin, which, in turn, slows down aging by acting on the gene and protein SIRT1.

Senile vagaries of nature

How our ideas about aging have changed, how some theories try to explain aging and its neglect, and why it is so necessary for a person to "disassemble" ageless animals to molecules.

What did the "lifetime machine" show?

Aging does not have a single molecular cause - it is a systemic process involving a complex biological network. Genetic processes and environmental factors are equally involved in the mechanism of aging.

Eternal life for solving problems

Is it possible to put a person's consciousness in a test tube when it will be possible to create an avatar for people and why potentially possible immortality is not the most attractive scenario of human life.

Will methylene inhibit premature aging?

Small doses of methylene blue almost completely eliminate defects in the cells of patients with progeria, as well as eliminate age-related damage to healthy cells.
