Why We Age
In 1993, molecular biologist Cynthia Kenyon and her colleagues published a revolutionary study demonstrating that mutating a single gene in the worm C. elegans doubled its lifespan. Compared to control worms, the mutant worms appeared younger by several key metrics. The landmark study fundamentally proved that aging is not an unchangeable , random biological process but a process driven by mechanisms that can be studied, influenced, and slowed. Kenyon's research marked the beginning of the modern study of biological aging (known as geroscience). Since then, research labs and companies have sprouted around the world aiming to research and rethink what it means to grow older. Kenyon's findings came at an important moment in history. Since the beginning of the 1900s Human lifespans have more than doubled, largely because of public health initiatives such as access to chlorinated water, vaccines, and penicillin. These initiatives helped to eradicate many of the deadly di...
