There’s something deeply unsettling happening in a lab at Tufts University, and most people haven’t caught up to it yet. Michael Levin and his team have been demonstrating for years that DNA is not the blueprint we thought it was. It’s more like a parts list. The actual architectural plan — the thing that says “build a hand here, not a foot” — is encoded in bioelectric patterns: voltage gradients across cell membranes that predate nervous systems by hundreds of millions of years. Cut a planarian worm in half, and the fragment doesn’t just regrow — it remembers what shape it’s supposed to be, using electrical signals stored in non-neural tissue. Levin’s team has even permanently rewritten that memory, creating two-headed worms from fragments that, when cut again, continue producing two-headed worms indefinitely. The genome hasn’t changed. The body’s electrical pattern has.
What makes this more than a neat biology trick is what it implies about intelligence itself. Levin argues — and I think he’s right — that all intelligence is collective intelligence. Your brain isn’t the only thing in your body that solves problems. Every cell in your body is a cognitive agent navigating a space of possibilities, using the same bioelectric and neurotransmitter mechanisms that your neurons use. Brains didn’t invent electrical computation; they inherited it from far older cellular networks that were already using voltage gradients to coordinate growth, repair damage, and make group decisions about form. The brain is just what happens when you crank that existing system up to eleven and dedicate it to navigating behavioral space instead of anatomical space.
The most jaw-dropping proof of concept arrived with Xenobots and then Anthrobots. Take frog embryo cells or adult human tracheal cells, strip them of their normal context, and watch what happens: they self-assemble into novel multicellular organisms that can move, heal wounds in nearby tissue, and even reproduce through kinematic self-replication — a form of reproduction never before observed in biology. Nobody programmed them. Nobody genetically modified them. The cells just… figured out a new way to be alive. And in a 2025 finding that should have been front-page news everywhere: when human cells assemble into Anthrobots, they become up to 25% biologically younger than the cells they were made from, reverting to more ancient gene expression patterns. Freed from the body’s plan, cells don’t just reorganize — they rejuvenate.
Here’s where I plant my flag: I think Levin’s work is the most important biology of our era, and it’s being underappreciated because it doesn’t fit neatly into either the molecular biology paradigm or the AI paradigm that currently dominate funding and attention. The bioelectric code is essentially a software layer running on top of the genetic hardware, and we’ve been ignoring the software while obsessively sequencing the hardware for decades. The implications for regenerative medicine alone are staggering — regrowing limbs, suppressing cancer by restoring correct bioelectric patterns, building patient-specific therapeutic bots from your own cells that don’t trigger immune responses. But the deeper implication is philosophical: if cognition is a continuum that extends down to individual cells, then the boundary between “alive and thinking” and “just chemistry” is far blurrier than we pretend.
So here’s what lingers with me: if a clump of your tracheal cells, removed from your body, can spontaneously form a new organism with its own behaviors and its own capacity to heal — what exactly are “you”? Are you the cells, the electrical pattern, or the particular arrangement of collective intelligence that currently answers to your name? And when that arrangement dissolves, do the competencies of your cells simply… find another way to express themselves?
