When we age, all parts of our body deteriorate over time. But while aging as a whole might be an accumulation of disparate processes, scientists have long wondered if it might be controlled by some central location in the body. Researchers have now uncovered an area in the brain about the size of an almond in humans that wields powerful control over the body’s aging process. By manipulating a single substance secreted by the hypothalamus they were able to extend the lives of mice. The work opens up the possibility that the hypothalamus may be an important target in treating age-related diseases such as heart disease and Alzheimer’s.
