The Spark of Life
Manage episode 507298980 series 61
In the 1920s, a Russian biologist studying onion roots made a surprising discovery: underground, down in the darkness, it seemed like the cells inside the onion roots were making their own … light.
The “onion root experiment” went on to become something of a cult classic in science, and eventually the biologically-made light was dubbed “biophotons.” In the ensuing century, biophoton discoveries moved from onion roots to bacteria, frog embryos, and humans. Today, scientist Nirosha Murugan is on a career-defining journey to learn more about the light. As she and her colleagues study this mysterious phenomenon, they find themselves racing from question to question, wondering what gives off light, where it might be coming from, and what, if anything, it could tell us about life, disease, and even death.
