Scientists have found a new way to slow down aging
A group of researchers has proposed a new way to slow down the aging process of living cells by manipulating DNA.
By studying the mechanisms of aging in yeast, scientists at the University of California, San Diego have found that despite their genetic similarity and the same habitat, they can age in very different ways. Approximately half of the cells studied died as a result of a gradual decrease in the number of nucleoli, while in others, mitochondria ceased to function.

After additional tests, the researchers found that cells began to follow one of two paths from the very beginning of their life, and identified a molecular circuit that determines the type of aging. This allowed the team to model the process and optimize it by reprogramming the genetic code, which dramatically increased the life span of the yeast.
Scientists say similar methods can also be used to delay human aging and improve health outcomes. Therefore, in the future, they will conduct experiments with complex cells and organisms.
