Can research into a rare, accelerated aging disease and "zombie cells" teach us something about the normal aging process? Did you know that a small molecule called NAD + plays a critical role in our ...

An international research team has uncovered new insights into healthy brain aging. The researchers found that aging leads to the accumulation of defective energy molecules in the brains of aged mice, ...

A new theory suggests many age-related diseases may actually start decades before symptoms appear. Researchers say early-life damage — from infections, injuries, or genetic mutations — can remain ...

Aging is a natural part of life, and most of us expect to see signs of aging in our 50s and 60s, such as wrinkles, gray hair, and slower metabolism. However, some people seem to age much faster than ...

A team of Japanese researchers say they’ve identified how a set of proteins in nerve cells declines with age, a discovery that may someday lead to a therapy to maintain brain health in later life. In ...

The nematode Caenorhabditis elegans has a simple nervous system consisting of just 302 neurones. The human brain, with approximately 90 billion neurones, is far more complex. Nevertheless, neurons in ...
