João de Magalhães, a scientist working on the biology of aging, maintains a database of genes related to human aging. Even if you're not someone who needs to dig up information on a specific gene (like PASG or HELLS, mentioned here yesterday), the introductory material makes for an interesting read. It's is good to note that the list of genes known to affect aging in mammals is growing. The modern field of bioinformatics has already greatly reduced the resources required to analyse and identify genetic information. This means that we can expect to learn far more of the way in which our bodies work in years to come. This knowledge can then be turned to therapies, cures and the fight against aging!
