Scientists find hidden driver of aging and a simple amino acid that fights memory loss in mice
Scientists discovered that declining levels of a protein called Menin may help drive aging, and restoring it in older mice reversed several age-related changes in just 30 days. Even more surprisingly, supplementing with a simple amino acid called D-serine improved memory and learning, offering a potential new approach to age-related cognitive decline.
