Theories of Everything with Curt Jaimungal · Michael Levin: Bioelectric Signals That Reprogram Living Organisms · 21 Mar 2025 podcast

Now now watching these patterns is is all well and good.

And in fact, you can use them to diagnose uh birth defects and and so on.

But of course, the more important thing is to start to rewrite these pattern memories.

So if I'm telling you that these are memories.

On the one hand, you want to be able to read and interpret them.

And on the other hand, you want to be able to reset them for for therapeutics.

And in order to reset them, we don't use um electrodes or fields or magnets.

There are no waves, no frequencies, nothing like that.

What we're doing is manipulating the natural interface that these cells are using to control each other.

So so on their surface, they have these ion channels which set the voltage.

And then here they communicate that voltage to each other.

So just like neuroscientists do, we take all of those tools and we can use pharmacology to turn the channels on and off.

We can use optogenetics and and so on.

And so we can control the voltage.

And the communication between cells.

So I'm going to show you very quickly three stories that illustrate why why this is powerful and why this is important.

And they work, not because we're so smart, they work because the system actually is using this electrical communication as a cognitive medium, as a decision-making uh substrate for uh determining growth and form of the organism.

So the first thing I'm going to show you is a quick story about cancer.

So if we take uh uh nasty human oncogenes uh like KRAST and and P53 mutations and so on, and we inject them into uh into tadpoles, they will eventually make a tumor.

But before the tumor it becomes apparent, you can already see using this voltage imaging, you can already see that uh that these cells have an aberrant voltage from their neighbors.
