With the help of science, could humans find a way to become old without getting elderly, a phenomenon otherwise known as "biological immortality"? In Ageless, Andrew Steele, research fellow at Britain's new and largest biomedical laboratory, the Francis Crick Institute, shows us that the answer lies at the cellular level. He takes us on a journey through the laboratories where scientists are studying every aspect of the cell--DNA, mitochondria, stem cells, our immune systems, even age genes that can lead to a tenfold increase in life span (in worms, anyway)--all in an effort to forestall or reverse the body's (currently!) inevitable decline. With clear writing and intellectual passion, Steele shines a spotlight on a revolution already under way and offers reality-based hope.
