Scientists from a mathematical point of view have proved that aging is inevitable
Scientists from the University of Arizona is mathematically proved that human aging is inevitable. Scientific study appeared in the journal Proceedings of the National Academy of Sciences of the United States of America (the official publication of the National Academy of Sciences of the United States). The details of the work retells Science Alert. Genetic engineering is trying to find effective ways to combat aging. Scientists want to learn how to suppress pigment the melanocytes, which make people closer to old age, gray hair, fight fibroblastami that at some point cease to produce sufficient amounts of collagen, resulting in wrinkles.
Multicellular organisms are doomed to a permanent "cell competition". The problem is that to replace bad or aged part of the structure is impossible without the generation of new problematic cells.
The researchers built a mathematical model based on the probability distribution of the effects of somatic mutations and other types of degradation of the cells. Based on the collected data scientists have created a coordinate system for describing the genotypes of cells. Each cell was analyzed by two parameters: the competitive potential and contribution to the viability of the organism. The emergence of new mutations, or hereditary changes in the cells depends on the current values of these two factors. According to evolutionary biologist Joanna Masel, human DNA is arranged in such a way that the pursuit of "eternal youth" will certainly lead to other problems. The researchers deduced the law, according to which the elimination of senescent cells in the body leads to the spread of cancers. Oils States that "aging is inevitable ... mathematically, logically, theoretically, and mathematically there is simply no exit".
On the other hand, if you try to fight cancer cells, then the other (still healthy, but already old cells) immediately "release out" all visible signs of aging: wrinkles, dry skin, gray hair.
