Venkatraman Ramakrishnan, A person of death. This doesn’t sound like a good moni kur, but it’s as follows: Ramakrishnan is one of the most prominent scientists in the world in the field of rescue biology and cell courses associated with aging and death. He won the 2009 Nobel Prize in Chemistry for discovering the structure of Ribosom, an important cytoplasm that is in charge of genetic expressions in 2009.
Ramakrishnan is not only a major researcher but also many authors. After great success Gene machineHe published the mighty, the memoir that talks about his human and scientific journey. Why we dieAs the name suggests, a book explains the mechanics that control aging and gradually and illegally.
Ramakrishnan was recently in Italy in Italy in Milan, where he gave a lecture in the second edition of the Milan Jangsu Summit, which is dedicated to longevity and psychological physical welfare hosted by the brain. It was an opportunity to meet him and ask some questions. This interview was edited for clarity and length.
Wired: Professor Ramakrishnan, the important question of the book is Why we die. But exactly what is death?
Venki Ramakrishnan: As death, we mean an irreversible loss of the ability to function as a consistent individual. For example, the result of the failure of an important system or device, such as heart, brain, lungs or kidney failure. In this sense, there is an obvious paradox. When our whole organism is alive, millions of cells in us are constantly dying, and we do not realize it. On the other hand, at the time of death, most of the cells of our bodies are still alive, the entire organs are still functioning and can be donated to those who need transplantation. But at that point, the body lost its ability to perform the entire function. In this sense, it is important to distinguish between individual cell death and death.
In terms of death and aging, you say in the most recent book, “I wanted to see our current understanding of the two phenomena objectively.” What is the greatest surprise or the deepest faith in writing and studying this work?
There were actually some surprises. One is that it is not programmed by our genes, as opposed to what death can think. Evolution does not care how long we live, and selects the ability to deliver genes, which are known as “fitness” in evolutionary biology. Therefore, the selected characteristics are the characteristics that help us survive and breed as a child. And later in life, these characteristics cause aging and decline.
Another curious discovery was that aging was not simply due to the wear of cells. Ware occurs constantly in all living things, but life is very different for each species. Instead, life span is the result of the balance between the consumption of the resources needed to maintain and repair organisms and the consumption of resources needed to maintain health and health until it grows and grows.
