I touched on the importance of biomarkers in my post on the meaning of aging, and was fortunate enough to have Aubrey de Grey on hand to offer useful commentary and clarifications.
Biomarkers for the aging process are an important issue in aging and serious anti-aging science. Stephen Gorden has followed up with thoughts and explanations at the Speculist. Aubrey de Grey offers more information on the topic there too.
As pointed out in the Speculist post, SAGE Crossroads has covered biomarkers in a webcast last year. The SAGE Crossroads site is turning into a very good resource for those seeking insight into the major issues and debates in aging science, as well as mainstream views of healthy life extension.
