- High-protein is a wellness craze, but could restricting it be anti-ageing?
Research in rodents suggests that restricting protein intake may slow aging and extend lifespan by improving metabolic health and reducing senescent cells, though human studies remain inconclusive. Experts debate whether high-protein diets are beneficial or harmful, with some cautioning that excess protein could negatively impact sedentary individuals.
- A grad student’s wild idea sparks a major aging breakthrough
Researchers at Mayo Clinic discovered that aptamers, tiny synthetic DNA molecules, can selectively attach to senescent cells linked to aging and disease. This breakthrough emerged from a casual conversation between graduate students and could enable more precise identification and targeting of these cells in living tissue.
