Autophagy is influential on aging, as many of the interventions capable of slowing aging in animal models involve increased autophagy. Better maintenance of cells means better tissue function and slower onset of age-related dysfunction.

Telomerase 'immortalizes' cancer cells, prevents tumors and slows a key stage in normal cell death. A new study found that telomerase reactivates in normal adult cells at a critical point in the aging process.

Fat tissue surrounding skeletal muscle contributes to declining muscle mass and strength. The most compelling evidence arises from transplantation of fat tissue between mice, showing that it produces harmful effects.

A meta-analysis demonstrated that aggressive control of blood pressure with mean systolic and diastolic BP levels less than 130 mm Hg and less than 85 mm Hg was beneficial for secondary prevention of stroke.
