The move from primary to secondary school is a major transition for many children, marked by new environments, new peers and increasing expectations. But while the jump signals growing up and greater independence, it also triggers a significant decline in student wellbeing, according to new research from Adelaide University.

Researchers at the Marshall University Joan C. Edwards School of Medicine have identified new evidence suggesting that tiny particles produced in the gut may help drive inflammation and chronic disease associated with aging. These findings offer new insight into how sleep, metabolism and immune health may be interconnected.
