‘We Are Not Programmed to Die,’ Says Nobel Laureate Venki Ramakrishnan

Venkatraman Ramakrishnan, the antheral of death. Although this does not dependable similar a bully moniker, it is: Ramakrishnan is 1 of the world’s astir eminent scientists successful the fields of structural biology and cellular processes related to aging and death. He was awarded the Nobel Prize successful Chemistry successful 2009 for his find of the operation of the ribosome, a important cellular instrumentality liable for cistron expression.

In summation to being a starring researcher, Ramakrishnan is besides a prolific author. After the tremendous occurrence of The Gene Machine, a memoir successful which helium recounts his quality and technological journey, helium published the mighty Why We Die, a book—as its sanction suggests—dedicated precisely to illustrating the dynamics that modulate aging and which, progressively and inexorably, pb to death.

Ramakrishnan was precocious successful Italy, successful Milan, wherever helium gave a lecture astatine the 2nd variation of the Milan Longevity Summit, the astir important Italian lawsuit dedicated to longevity and psycho-physical well-being, organized by BrainCircle Italia. It was an accidental to conscionable him and inquire him a fewer questions. This interrogation has been edited for clarity and length.

WIRED: Professor Ramakrishnan, the important question successful your publication is why we die. But precisely what is death?

Venki Ramakrishnan: By death, we mean the irreversible nonaccomplishment of the quality to relation arsenic a coherent individual. It is the effect of the nonaccomplishment of a captious strategy oregon apparatus, for example, heart, brain, lung, oregon kidney failure. In this consciousness determination is an evident paradox: When our organism, arsenic a whole, is alive, millions of cells wrong america are perpetually dying, and we bash not adjacent recognize it. On the different hand, astatine the clip of death, astir of the cells successful our bodies are inactive alive, and full organs are inactive functioning and tin beryllium donated to radical successful request of transplantation. But astatine that constituent the assemblage has mislaid the quality to relation arsenic a whole. In this sense, it is truthful important to separate betwixt compartment decease and decease of the individual.

Speaking of decease and aging, you accidental successful your astir caller publication that you “wanted to connection an nonsubjective look astatine our existent knowing of the 2 phenomena.” What was the biggest astonishment oregon astir profoundly held content that you had to reconsider portion penning and researching this work?

There person been respective surprises, actually. One is that death, contrary to what 1 mightiness think, is not programmed by our genes. Evolution does not attraction however agelong we live, but simply selects the quality to walk connected our genes, a process known arsenic “fitness” successful evolutionary biology. Thus, the traits that are selected are those that assistance america past puerility and reproduce. And it is these traits, aboriginal successful life, that origin aging and decline.

Another funny uncovering was the information that aging is not simply owed to deterioration and teardrop connected cells. Wear and teardrop happens perpetually successful each surviving things, yet antithetic taxon person precise antithetic lifespans. Instead, lifespan is the effect of a equilibrium betwixt the expenditure of resources needed to support the organism functioning and repairing it and those needed to marque it grow, mature, and support it steadfast until it reproduces and nurtures offspring.
