Fundamentally hardware error, meaning the mutation, you fix it in software.
You fix it by a uh a a a computer designed a brief biochemical intervention that resets the electrical patterns so that the tissues know what to do.
And then they bring a they make a correct ring.
And um the final story that I'm going to tell you is about uh regeneration, limb regeneration.
So
Uh, fro adult frogs do not regenerate their legs, unlike salamanders.
So if they happen to lose a leg, then 45 days there's basically later, there's basically nothing.
So we asked uh the question: could we uh communicate with these cells through the bioelectrical interface and guide them towards the leg growing path in anatomical space instead of the scarring path?
And so we designed a cocktail, um, uh basically a 24-hour
hour application of that cocktail uh ends up uh with uh d driving about a year and a half of leg growth.
So at that point, immediately within the first twenty four hours, you get the pro regenerative genes coming on here.
This is MSX one.
You then by forty-five days you've already got some toes, you've got a toenail, eventually a pretty respectable leg and it's touch sensitive and it's motile.
Okay.
So
Again, keep in mind that in this case, we did not uh have to uh manipulate that process during that whole time.
We didn't have to talk to the stem cells.
There are no scaffolds here.
Um, we didn't have to uh micromanage it at all.
We provided a very early signal that said, go down the leg building path.
