Cells use 'bioelectricity' to coordinate and make group decisions

For those interested in more details and quite mind blowing examples, here is a fascinating interview with Michael Levin (one of the researchers mentioned in the article).

Start at 1:19:11, the stuff before is him talking about biology, but from an intelligence perspective. After this time stamp is his retrospective on his bioelectricity research over the years, showing also examples of how they got a frog embryo to produce eyes, and many more things.
Thanks for sharing this timestamp - Levin's retrospective on bioelectricity research is compelling. What fascinates me most is how his work challenges the gene-centric view of development. The experiments showing bioelectric patterns can override genetic instructions (like inducing eye formation in non-eye tissue) reveal a whole layer of morphogenetic information we're just beginning to understand.
Even since reading about Michael Levin's work, I've been sold that there is a lot going on in terms of bioelectricity outside of neurons. But I haven't seen that much progress. This is one interesting, albeit simple example.
>In this way, bioelectrical flow across cell membranes lets tissues test which cells are the least healthy and mark them for extrusion. “They’re always pushing against each other and bullying each other. And what they’re doing is probing each other for which one’s the weakest link,” Rosenblatt said. “It’s a community effect.”
This fits with my model of how high levels of cooperation succeed in biology. Even in a community as homogeneous as cells you have the risk of defectors (cancer), or just poor members. As such you need a process to continually test your community members.
Electricity is the core of a single cell functionality as well, most biomolecules are on the exact boundary between a conductor and an insulator (and likely switch the state based on other molecules binding, pH, etc). A group of cells electricity is a higher level abstraction of that.

Could this lead into how there are people who thing non ionising radiation sources affect them?
So this is sort of.. environmentally available electrical potential in the cell? Or is it more constrained than the venues from the heart and the cell to other specific venues?
It'll blow their minds when they start researching chi kung and realise it's possible to draw in more energy by breathing and move it round the body. It's also possible to feel some kind of field around the body.
Auras and chakras don't sound so silly now do they.
"It'll blow those Chemists' minds when they start researching Alchemy and they realize the incredible power of mercury and lead to rejuvenate the body and lead to an elixir of youth!"
"It'll blow those Astronomers' minds when they start researching Astrology and the powerful effect of being born under auspicious constellations!"

If the ancient guru knowledge is so great, what testable predictions does it offer, where "auras" are a causal mechanism?
In other words, not: "Thou must intake the golden aura of oats and fiber by eating some, to counter the dark brown blockage of your Pu-point." The folk remedy might well solve your constipation, but it wouldn't be evidence for the mythology around it.
It feels really great to wield the scientific method and feel supercilious to all other people and ideas that do not arise from such infallible reasoning, and sure the progress of humanity hockey sticked since empiricism took hold. But let's not forget that empiricism is limited by what we can/want/think to measure.
Like it's pretty well accepted that breathing exercises have physiological and mental health benefits but it took decades of consumerist appropriation of yoga and other techniques before academia properly found the motivation to earnestly investigate that yes breathing exercises are indeed good for you.
As someone who is a deep practitioner of martial arts and athletics, if the metaphors of qi gong and yoga were purely powerful visualisation aids that already provides more than enough tangible benefit. I don't need scientists to tell me that qi is good for my body - I can feel it.
So let's keep an open mind, our ancestors were anything but idiots.
Proper hatha yoga (not the modern hijacked nonsense) is literally a predictive method to experience deeper aspects of oneself, one part of which is a greater sensitivity to energy movements and corresponding fields.
There is already western research on kundalini, the most potent example of bioelectrical energy, and changes in energy potential experienced by meditators. Not to mention countless empirical self-reports (upon which a good scientist would keep an open mind).
But don't let facts get in the way of your prejudices.
Lol no, this crank shit sounds dumb as fuck haha. Kamehameha!
Here's a study from 2023 where they apply external electricity to improve healing rate of wounds:

It enabled healing of diabetic wounds that are otherwise hard to heal.
