Everyone ages. Growing old is a fundamental feature of human existence.
Though we might not always be aware of aging, it looms in all of our futures. As Science News editor in chief Eva Emerson writes, “Aging happens to each of us, everywhere, all the time. It is so ever-present and slow that we tend to take little notice of it. Until we do.”
But, our scientific understanding of aging pales in comparison to its significance in our lives. While new studies reveal exciting prospects for slowing the effects of aging, its causes and extensive effects remain enigmatic.
Scientists are still divided on some fundamentals of aging, and that’s why aging research raises some interesting questions. For example, how does it change the brain? How did different life histories evolve? How old is the oldest blue whale? This special report addresses those questions and more.
AGING EXPLAINED Aging is more than candles on a birthday cake. The aging process manifests differently in our cells, in our brains and in other species.Production: H. Thompson; Art direction: E. Otwell; Music: Blue Dot Sessions.
