Shorten the death spiral

Perhaps studying the phenomenon that researchers have called the "death spiral" will someday give people the opportunity to stay healthy for the rest of their lives.

Why Aging can be Avoided

The huge variety of types of aging in plants and animals should alert lovers of generalizations – especially against generalizing the inevitability of aging.

You can 't forbid living for a long time

It is still very early to talk about the victory over old age. Nevertheless, the discoveries already made give hope that someday a "cure for old age" - or at least a slowing down of old age – will still be created.

Hoarding is to blame for old age

We age because various imperfections accumulate in the body, which, at the molecular, cellular, tissue and organismal levels, eventually lead to the death of an individual.

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.

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.

Molecular and cellular biology of aging

The Society of Gerontologists of the USA has published a unique e-book “Molecular and Cellular Biology of Aging” available for download, containing detailed reviews of all levels of the aging process of many organisms, from microbes to humans.

Aging of cells and aging of the body

More and more data indicate that aging is not the result of a harmful program, but a consequence of excesses in the work of mechanisms that, with moderate activity, are beneficial.

A new reason has been added to aging

With age, proteins in the cell begin to fold poorly due to changes in the redox potential at the assembly sites of protein molecules.

Evolution doesn't need "longevity genes"

Interview with chemist Mikhail Shchepinov about the phenomenon of aging, theories explaining this process, and the goals of evolution.

The unsolved mystery of centenarians

Despite the increasing intensity of the search for the causes of longevity every year, the researchers have not found an answer to the question "Why do some people live 115 or even 120 years?".

Scientists have corrected the defect underlying premature aging

Using an HTRA3 inhibitor – the "culprit" of a rare hereditary disease or an antioxidant neutralizing free radicals, the researchers managed to suppress the activity of the HTRA3 enzyme in the cells of patients with Coccain syndrome to a normal level.

Another aging mechanism has been identified

The data, according to which the aging process is closely interrelated with the violation of the structure of heterochromatin, indicate a new promising direction in the development of methods for the prevention and treatment of age-related diseases.

How we age

Starting from DNA damage and ending with disruption of intercellular interactions, aging is a mysterious and versatile process.
