"I haven't been a young scientist for a long time. Today I come here on behalf of old scientists." recently, nearly 80 year old Nobel Laureate in physiology or medicine Owen Neha made the following speech at the world's top scientists forum held in Shanghai. In March 2019, Erwin Neher joined Nell neuroplasticity Laboratory of Shenzhen Institute of advanced technology, Chinese Academy of Sciences.
How do the world's top scientists view aging? How did you associate with yourself when you were old? At this forum, Neil, Franz ulrici Hartle, winner of Lasker basic medical research award in 2011, maikehuo, winner of Lasker basic medical research award in 2017, Hans clives, winner of breakthrough award in life science in 2013, and Mei Tian, Professor of human clockwork Institute of Fudan University jointly discussed this topic.
Nobel laureates cannot escape aging
In 2019, the United Nations world population data outlook report pointed out that human life expectancy was 72.6 years, an increase of more than 8 years over 1990. The concerns about human life expectancy and aging go hand in hand with an increasingly huge society.
When we regard aging as the only way in life, the curious hard threw out a series of questions. Why do humans age? Why are mammals such as cats and dogs so different from humans?
Hall answered this question from the perspective of evolutionary pressure. 100 years ago, when there was no competitive pressure for survival, people's life was still young. Now, humans need to live longer. Fertility is not only pressure, but also the pressure to cultivate the next generation and the next generation may make people live longer.
"Different species have different survival pressures," Cleveland attributed to "Earth's choice". "If humans and most animals do not eventually disappear, the planet will be overcrowded."
Neil had the most say in the forum and expressed his views on "getting old". After retirement, Nell continued his research. Only by solving the health problems caused by aging can human beings carry out better research. "Although my workload has been reduced a lot, I believe there are still many ways to make us active. Thinking is not equal to resigning mentally."
"A researcher said that the average life span of Nobel laureates is longer than that of ordinary people, so your scientific research career may be longer than that of other scientists." Hart joked to Neil.
"Maybe it's because Nobel laureates eat more chocolate than others. Has anyone studied the relationship between chocolate and health?" Neil said
In fact, the mechanism of human aging is indeed affected by many factors, and its mystery has not been fully understood.
Indeed, aging is not just a human thing, and the attempt to resist and delay aging is not just a human thing. Although rapamycin has been proved to be a drug to delay the aging of experimental mice, a series of ethical issues such as whether it can be used in humans, whether it will produce side effects and who can obtain the right to use it complicate this debate.
At the molecular level, human aging
