It has long been understood that parents' income plays a major role in children's access to higher education. But a new study published in Canadian Studies in Population suggests that grandparents' income matters, too. By analyzing multigenerational tax data, researchers at Université de Montréal found a direct and significant correlation between grandparents' earnings and the likelihood that their grandchildren will pursue postsecondary education.

By integrating findings from 140 studies and nearly 66,000 individuals, researchers from the Biosocial team at the Max Planck Institute for Human Development in collaboration with Columbia University in New York have shown that lower socioeconomic status and exposure to discrimination are consistently associated with accelerated biological aging, measured in the epigenome.
