New research shows that E-TCmito is an important link between neuronal activity and mitochondrial function, highlighting its potential to counteract cognitive decline in old age and in diseases such as Alzheimer's.

The results of a new study suggest that the biochemical and physical effects of exercise could contribute to nerve healing.

Ketone bodies, which are known for their role in energy metabolism during fasting, have been shown to interact directly with damaged proteins in the brain and promote their breakdown through autophagy. The researchers found that the ketone body β-hydroxybutyrate alters the solubility of the misfolded proteins, which facilitates their breakdown and reduces pathological aggregation.

In a randomized controlled trial published in the journal Nutrients, researchers tested supplementation with resveratrol, vitamin C, and a combination of the two. They found that all treatments had a similar positive effect on oxidative stress in postmenopausal women.

Mayo Clinic researchers have discovered that senescent cells — non-dividing zombie cells — build up in the skin as we age and can influence the aging process in other parts of the body. Their latest study showed that transplanting aging skin cells in a preclinical model not only led to the spread of aging to other tissues, but also accelerated physical decline, impaired muscle function, and worsened brain health. This discovery suggests that senescent cells in the skin could cause wider systemic aging.
