The immortalist

Alan Harrington

In 'The Immortalist', Alan Harrington presents a bold argument for achieving immortality through scientific advancements, critiquing religious and philosophical perspectives that accept mortality. He advocates for a concerted effort to extend human lifespan, drawing parallels with ambitious projects like the Apollo missions. The book delves into the implications of immortality on human society and existence.

Why We Age—and Why We Don’t Have To

David Sinclair

In this book, Dr. David Sinclair presents a bold new theory on why we age, arguing that aging is a disease that can be treated. He discusses recent breakthroughs from his own lab at Harvard, including the activation of newly discovered vitality genes and the role of epigenetics and metabolism in aging. The book explores lifestyle changes such as intermittent fasting, cold exposure, and exercise, as well as emerging anti-aging therapies, to help people live younger and healthier for longer. Sinclair also delves into the philosophical and ethical implications of extending human lifespan, emphasizing that these methods are not against nature but rather a continuation of human efforts to improve health and longevity.

Pleiotropy, Natural Selection, and the Evolution of Senescence

George C. Williams

This influential paper by George C. Williams explores the concept of antagonistic pleiotropy as an explanation for the evolution of senescence. It builds upon ideas similar to those of Peter Medawar, discussing how natural selection's effectiveness decreases with age, leading to the accumulation of genes with early benefits but late-life costs.

The Limit on Human Lifespan

Exploring the Biological and Physiological Bounds

Not specified

Research suggests that there may be a biological limit to human lifespan, potentially ranging between 120 and 150 years. This limit is influenced by factors such as the body's ability to repair itself and the onset of age-related diseases. While some studies propose a fixed limit, others argue that advances in medicine could potentially extend lifespan beyond current records.

2018 Breakthroughs in Science

Biomedical Research and Other Notable Discoveries

Various Researchers

In 2018, several groundbreaking studies were published, including those on single-cell analysis, RNA drugs, and phase separation in cells. These discoveries were highlighted as part of *Science*'s Breakthrough of the Year, focusing on biomedical sciences and their potential to transform our understanding of life and disease.

Jeanne Calment lived her entire life in the South of France. She filled her days with leisurely pursuits, enjoying a glass of port, a cigarette and some chocolate nearly every day. In 1997, Ms. Calment died. She was 122.

With medical and social advances mitigating diseases of old age and prolonging life, the number of exceptionally long-living people is increasing sharply. But no one is known to have matched, let alone surpassed, Ms. Calment’s record.

Longevity scientists hold a wide range of nuanced perspectives on the future of humanity. Some consider life span to be like a candle wick, burning for a limited time. While others view it as a supremely, maybe even infinitely elastic band.

As the eminent physicist Richard Feynman put it in a 1964 lecture, “There is nothing in biology yet found that indicates the inevitability of death.”
