<p><b>How recent breakthroughs in longevity research offer clues about human aging</b><br><br>All of us would like to live longer, or to slow the debilitating effects of age. In<i> How We Age</i>, Coleen Murphy shows how recent research on longevity and aging may be bringing us closer to this goal. Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging. Understanding the fundamental biological rules that govern aging in model systems provides clues about how we might slow human aging, which could lead in turn to new therapeutics and treatments for age-related disease.<br><br>Among other vivid examples, Murphy describes research that shows how changing a single gene in the nematode worm <i>C. elegans</i> doubles its lifespan, extending not only the end of life but also the youthful, healthy part
