Like big, tall trees in old-growth forests, older animals are irreplaceable. Pulling them out leaves the ecosystem less resilient to future shocks. It’s time for ‘longevity conservation’ measures.
Aging is a major risk factor for many chronic diseases. Figuring out what influences longevity and how to identify rapid agers could lead to healthier and longer lives for more people.
The protective caps at the ends of chromosomes naturally shorten over time. Researchers found that direct damage can prematurely trigger senescence and contribute to age-related diseases like cancer.
Life-extension therapies may be coming sooner than you think.
Healing is a complicated process. As people age, higher rates of disease and the fact that old cells lose the ability to divide slow this process down.
Global warming has increased plant growth and helped offset increases in carbon dioxide emissions.
