An Overview Of Aging Science

The cover story for Chemical and Engineering News provides a good overview of some of the more recent aging science - and what we could to to slow or halt the aging process. The bulk of the article focuses on scientific research stemming from calorie restriction: investigations into the genetic and biochemical mechanisms by which CR extends healthy life span and reduces the risk of suffering age-related degenerative conditions. Work on telomeres - the protective caps at the ends of our chromosomes that serve a number of important functions - also gets a mention, as does research into how we lose our ability to heal ourselves as we age. "A decline in Notch signaling in [stem cells] may be a general mechanism underlying the diminished regenerative properties of aged tissues."
