Researchers here mine patient data in order to demonstrate that type 2 diabetes combines with the age-related stiffening of blood vessels to produce greater structural damage in the brain, leading to a more rapid cognitive decline. This correlation between stiffening and damage was not observed in non-diabetic patients. This is […]

Most of the work aimed at treating aging as a medical condition is focused on stress response upregulation, finding ways to trigger some of the regulatory pathways and mechanisms involved in beneficial cellular reactions to the mild stresses of exercise, reduced calorie intake, hypoxia, heat, cold, and so forth. Improved […]

There have been suggested that metformin, a at best weak calorie restriction mimetic, can suppress some of the beneficial metabolic response to exercise. Metformin is in general a poor choice in comparison to mTOR inhibitors when it comes to animal evidence for an ability to modestly slow the progression of […]

In a seminal 2013 study, MDI Biological Laboratory scientist James Godwin, Ph.D., discovered that a type of white blood cell called a macrophage is essential to limb regeneration in the axolotl, a Mexican salamander that is nature’s champion of regeneration. Without macrophages, which are part of the immune system, regeneration […]

Genes determine species longevity, though within a species, and particularly within our species, the estimated involvement of genetic variants in individual life expectancy is becoming ever smaller as ever more data accumulates. Nonetheless, researchers are very interested in the comparative biology of aging, the question of why long-lived species are […]
