Dr. Bill Andrews explains the groundbreaking science of telomere biology, a technology that holds the promise of one day treating and reversing age-related diseases, including aging itself. Topics discussed include the biological basis for the human aging process, the basic science behind telomeres and telomerase, a history of Dr. Andrews' discoveries at Sierra Sciences, the most exciting experiments demonstrating the promise of therapies based on telomere length maintenance, and the diseases that could be treated when this technology comes to fruition. Dr. Andrews is the President and CEO of Sierra Sciences, a biotech company focused solely on reversing aging through telomere maintenance. He is one of the principal discoverers of both the RNA and protein components of human telomerase, the enzyme most critical to this technology. He has focused the last 20 years of his career exclusively on addressing the problem of human aging.
