Why do nerve cells die

If clusters of pathologically folded proteins in the nuclei of neurons practically do not affect their functions, then protein aggregates located in the cytoplasm disrupt important transport routes between the cytoplasm and the nucleus.

The effect of stress on telomere length has been questioned

The largest meta-analysis to date has found a practical lack of connection (and even a negative, albeit weak, correlation) between stress and telomere length.

The health of Homo sapiens and the genes of its "cousins"

From the fact that most of the Neanderthal genes did not benefit our ancestors, it does not follow at all that the indigenous Neanderthal population of Western Eurasia could not pass on some useful alleles to people from Africa.

Fat people live longer than skinny ones

Yeast cells with a large amount of fat deposits live longer than "thin" ones, which confirms the so-called obesity paradox, according to which the mortality rate from all causes for overweight people is lower than for slim ones.
