Why We Die: The New Science of Aging and the Quest for Immortality

The knowledge of aging and death has driven human culture, including our religions, ever since we became aware of our mortality. For much of our existence there was not much we could do about it. But over the past few decades, biology has made major advances in our understanding of the causes of aging, opening for the first time the possibility of intervening in the process. At the same time, the combination of longer lives and reduced fertility rates means that many societies are faced with an aging population. This has led to large investments in aging research from governments and private industry funded largely by tech billionaires, resulting in both real advances and a large amount of hype. In this talk, Venki Ramakrishnan will discuss some of the key findings about why and how we age and die and prospects for the future. He will also explore the possible consequences of societies with extremely long-lived populations.

Venki Ramakrishnan is on the scientific staff of the MRC Laboratory of Molecular Biology in Cambridge, England. He has a long-standing interest in the structural basis of protein synthesis in the cell, which involves translation of genetic information on mRNA by the ribosome. For his work, he was elected a fellow of the Royal Society in 2003, a member of the National Academy of Sciences in 2004, and shared the 2009 Nobel prize in Chemistry.
