In this groundbreaking film, physicist Jim Al-Khalili investigates one of the most fascinating frontiers of modern science, quantum biology. Could the strange rules of quantum physics actually explain how life works? From the quantum tunneling that drives enzymatic reactions to the coherent energy transfer in photosynthesis, the film reveals how living systems might harness quantum mechanics to achieve extraordinary efficiency. Al-Khalili also explores how migratory birds may use quantum entanglement in their eyes to navigate thousands of miles and how even our sense of smell could depend on subatomic vibrations. This film challenges our understanding of biology, suggesting that the secret to life itself may lie in the quantum world.
