Diluting the blood plasma of older mice by replacing half of it with saline and albumin was able to reverse signs of aging by acting as a molecular reset to reduce inflammatory proteins.

Older adults who regularly volunteer (for at least 100 hours per year, or 2 hours per week) have significantly reduced risk of mortality, as well as an improved sense of well-being and optimism.

The molecule BAM15, a small mitochondrial uncoupler, reduced body fat and insulin resistance in mice without affecting appetite, which could treat obesity and fatty liver and slow down aging.

Repetitive negative thought patterns are linked to an increased risk of Alzheimer's disease, dementia, and pre-dementia signs including a build-up of amyloid and tau proteins in the brain.
