The BBC reports on a new study into the genetics of natural longevity. This Italian team says that "once they have found the genes which govern ageing, they hope to develop medicines which allow people to stay healthy for longer." Genetic studies of long-lived people are already producing results in the US, and should continue to shed light on new directions for research. Effective therapies result from an understanding the condition under treatment, and advances in medical research technology are proving their worth in this respect. Scientists today have a vastly greater understanding of genetics and cellular biochemistry than they did just five years ago. We live in interesting times!
