Turnover of fat tissue decreases as we age and makes it easier to gain weight. This study supports previous research that states exercise is a beneficial way to increase lipid turnover.

Somatic mutations are DNA changes that occur throughout someone's life, which can affect someone's risk of developing heart conditions and cancer, as well as accelerating biological age.

Inhibiting mTOR pathways has been shown to slow aging. Rapamycin has been found to inhibit mTORC1 and protect some organs against age-related decline, but its effect on skeletal muscle has not yet been studied.

Liver regeneration occurs in young mammals but declines upon aging. This study investigated whether cellular senescence plays a role in the loss of the liver's capacity to regenerate in adult mice.
