Studying a tiny worm, Caenorhabditis elegans, scientists discovered that a gene which regulates glucose (sugar) metabolism may also enhance longevity. The principle investigator, Dr. David Finkelstein, says, "this finding suggests that altering glucose metabolism could be a key to slowing aging in higher organisms, even perhaps in humans."

Working with a variety of taxa from mice to monkeys, scientists interested in the causes of aging have recently made significant advances in scientists' understanding of the aging process. Researchers have long realized that aging and the pathologies associated with it have evolutionary, physiological and genetic causes, although the relative influence of each of these has been debated. By testing hypotheses in diverse fields, and with a variety of species (from short-lived to long-lived), researchers are growing closer to building an understanding of the mechanisms underlying the aging process.
