Some older adults continue generating new neurons at higher rates. Individuals with exceptional cognitive performance showed roughly double the hippocampal neurogenesis compared with typical older adults.

A short cognitive training program may have decades-long benefits. Adaptive speed-of-processing training in older adults was linked with better long-term brain outcomes.

Circadian health matters for longevity. A compound called Mic‑628 can speed up circadian realignment—in mice, it nearly halved recovery time after a simulated 6‑hour time zone shift.

Polygonum multiflorum may support hair regrowth. Lab studies suggest it influences multiple pathways that protect and activate hair follicles.
