Scientists from Germany, the Netherlands, the United States and Japan have found a simple way to confirm longevity. The related research was published in nature communications, a sub Journal of nature.
Experts have found a correlation between the size of free-living nematodes’ nuclei and their lifespan. The smaller the nucleus, the longer the life expectancy of the animal. Similar patterns were found in Drosophila and rodents. Scientists have found that frequent physical activity in animals can lead to a decrease in the number of nuclei.
Muscle biopsies of people over 60 years old show that this rule is also applicable to people.
The researchers also determined that the smaller the nucleus, the less nucleolar fibrin there was. Scientists believe that the size of the nucleus can be used as an indicator of the length of life expectancy.
