Aging is a natural law, but people have been trying to stop this process. The sad news is that perhaps all attempts are in vain - American researchers have shown that it is impossible to prevent the aging of multicellular organisms like humans from a mathematical model.
Professor Joanna Masel of the University of Arizona collaborated with his postdoctoral fellow Paul Nelson to study aging mathematically and published an article in the American Academy of Sciences PNAS "Intercellular Competition and Inevitability of Multicellular Aging". Avoid aging)". In explaining the results of the study, Professor Masel said: "Aging is mathematically inevitable. There is no solution in logic, theory, or mathematics."
The age of growth will be a dilemma
According to the current understanding of aging: If you can make the living cells perfect for the fittest, there is a possibility to stop aging. One approach is to use intercellular competition to eliminate dysfunctional "stagnation" cells associated with aging while keeping other cells intact.
However, Professor Masel and Paul Nelson believe that this solution is not so easy to implement. Nelson explained that as you get older, there are two things happening on your body: First, the cells slow down and begin to lose function, for example, when your hair cells stop pigmentation; the other is that some cells increase their growth rate. , which leads to the formation of cancer cells. As we age, people form cancer cells to some extent in the body, even if they do not cause symptoms.
Nelson said: "As you get older, most of your cells begin to shrink and lose their function, and they stop growing. But some cells grow crazy. What we want to say is that this creates a dilemma. If you get rid of slow, slow-moving cells, then this will allow cancer cells to proliferate; if you slow down those cancer cells, it will allow slow-growing cells to accumulate. Can't do another."
The mathematical model answers that aging is an intrinsic property of multicellular organisms.
Although human death is an indisputable fact of life, the researchers proposed the first general model of the interaction between cell-to-cell competition, aging, and cancer to show why aging is an "unbreakable truth" and "multi-cell." The intrinsic properties of living things." The model results tell people how to think about the evolution of aging and the role of intercellular competition in aging and cancer.
Also, according to mathematical formulas, trying to fix them will make things worse. Professor Masel said: "You may be able to slow down aging, but you can't stop it. You can solve a problem, but you are stuck on another problem. Things will get worse and worse as time goes by."
