The Spark of Life
Host Molly Webster speaks with applied biophysicist Narosha Murugan about the discovery that living cells emit extremely faint light tied to their metabolism, and explores how this challenges the traditional lock-and-key view of cellular signaling. They discuss possible mechanisms for how this light is generated in mitochondria and potentially guided through cellular structures, its hypothesized roles in brain function and consciousness, and how its distinct signatures can already be used experimentally to detect cancer and distinguish living from dead tissue. The conversation ends with reflections on "life flashes" at fertilization and death, and on thinking of living beings as organized patterns of energy and light.
