Could belonging be a biological shield? Researchers uncover aging clues

Researchers analyzing over 2,100 adults from the MIDUS cohort found that individuals with higher cumulative social advantage, spanning community ties, family relationships, and religious support, showed slower biological aging and lower systemic inflammation. The findings suggest that long-term social resources may become biologically embedded, influencing molecular pathways linked to longevity.

Evolutionary mutation in cGAS enhances naked mole-rat DNA repair

The secret to the naked mole-rats' extraordinarily long life may lie in subtle changes to just four amino acids, researchers report. According to a new study, evolutionary mutations in cGAS – an enzyme in the innate immune system that senses DNA to trigger immune responses – may enhance the animal's ability to repair aging-related genetic damage, whereas in other species, such as mice and humans, cGAS can suppress DNA repair.
