Researchers at the University of California, San Francisco, have discovered a mechanism by which exercise helps protect the brain from age-related damage associated with Alzheimer's disease. Physical activity prompts the liver to release an enzyme that repairs the blood-brain barrier, reducing inflammation and improving memory in older mice. The findings, published in the journal Cell, highlight a body-to-brain pathway that could lead to new therapies.

A large UK study of over 33,000 low-activity adults has found that accumulating daily steps in longer, uninterrupted sessions is linked to significantly lower risks of early death and cardiovascular disease, compared to short bursts of walking. The research, published in Annals of Internal Medicine, suggests that how steps are grouped matters as much as total step count for those walking fewer than 8,000 steps per day.

Nigeria's Navy Chief has launched the annual sea exercise involving 16 warships. The initiative underscores the country's commitment to maritime readiness.

Walking in bouts of 10–15 minutes or longer was associated with substantially lower cardiovascular risk among adults taking fewer than 8,000 steps a day, with 15‑minute‑plus bouts tied to about a two‑thirds lower risk than very short walks, according to research published in Annals of Internal Medicine.

Using data from activity trackers, researchers found significant sex differences in exercise benefits for heart health. The findings suggest a need for updated, gender-specific health guidelines.
