The Biology of Aging and Longevity

The Biology of Aging and Longevity is a self-paced learning path in Biological Sciences, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify core biological markers of aging; explain evolutionary theories regarding lifespan; describe the role of genes in aging.

Conductor

The Conductor

Welcome aboard this journey into the ticking clock of your own cells. We will explore why nature designed us to fade and how science seeks to push back the horizon of time.
