In this video, Dr. Michael Levin discusses his research on bioelectricity, the electrical activity within living systems. He explains how this electrical signaling plays a crucial role in development, regeneration, and disease, challenging the conventional understanding that DNA is the sole determinant of biological outcomes. The conversation explores how manipulating bioelectricity could lead to new therapeutic approaches for birth defects, cancer, and aging, and touches upon broader philosophical implications regarding intelligence and consciousness.
Dr. Levin defines bioelectricity as the way living systems use the physics of electricity to perform their functions. He outlines two main types:
Dr. Levin discussed several experiments involving flatworms (planaria):

Here are some of Dr. Levin's key quotes about bioelectricity from the transcript:
Dr. Levin explains that the genome provides the cellular "hardware" – essentially, the factory settings or the physical components that a cell can use. Bioelectricity, on the other hand, acts as the "software" or the controlling layer.
The key difference lies in their function:
He emphasizes that bioelectricity is reprogrammable and can even override genetic predispositions, suggesting that it plays a more active and instructive role in shaping the organism than DNA alone.
Dr. Levin proposes that manipulating bioelectricity can offer therapeutic avenues for these conditions by restoring normal cellular communication and function:
Dr. Levin uses the term "diverse intelligence" to describe the idea that intelligence is not confined to brains and neurons. He posits that intelligence, defined as problem-solving, memory, and goal-directed behavior, exists in many forms and has been present in biological systems long before brains evolved.
Understanding that intelligence exists beyond the brain is important for several reasons, according to Dr. Levin:
Dr. Levin connects bioelectricity to consciousness by suggesting that consciousness, like other cognitive functions, is not limited to brains or neurons but is a broader phenomenon. He proposes that consciousness might be related to the "viewpoint of a pattern projecting into physical space."
Here's a breakdown of his ideas:
In essence, Dr. Levin suggests that the fundamental reality might be composed of these abstract patterns, and consciousness is the experiential aspect of these patterns interacting with the physical world through various interfaces, which could include not just brains but also simpler biological systems or even computational devices.
Dr. Levin describes the bioelectric code as the language of electrical signals that cells use to communicate with each other. It functions as a crucial communication system by:
Dr. Levin's research into bioelectricity has significant practical implications and potential future applications across medicine and technology:
In essence, Dr. Levin's work bridges fundamental biology with engineering and computer science, suggesting that by understanding and manipulating the electrical language of life, we can unlock powerful new approaches to health, healing, and technological innovation.
Dr. Levin referenced experiments with tadpoles that demonstrated bioelectric memory and supported the idea that morphology is controlled by bioelectric patterns:
Dr. Levin explains aging through the lens of goal-directed systems by suggesting that biological systems, particularly at the cellular collective level, are programmed to achieve and maintain specific states or "goals."
Here's how he breaks it down:
In essence, for Dr. Levin, aging isn't just about accumulated damage; it can also be a consequence of biological systems, which are fundamentally goal-oriented, losing their active direction and alignment over time. The bioelectric signals that normally guide these goals become less effective, leading to the decline associated with aging.
