Globally, scientists are working to unlock the secrets of extending human lifespan at the cellular level, where aging occurs gradually due to the shortening of telomeres–the protective caps at the ends of chromosomes that function like shoelace tips to prevent unraveling. As telomeres shorten over time, cells lose their ability to divide for healthy growth, and some eventually begin to die.
Scientists create genetically engineered mice that may help accelerate anti-aging research
