Scientists have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body.  The discovery, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan, they claim. The hypothalamus was known to regulate important processes including growth, development, reproduction, and metabolism.  In 2013, researchers made the surprising finding that it also regulates aging throughout the body. Now, the

same scientists have now pinpointed a tiny population of adult neural stem cells, known to be responsible for forming new brain neurons, that control aging. Study senior author Professor Dongsheng Cai, of Albert Einstein College of Medicine in the US, said: “Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging.  READ MORE
