Biologist Michael Levin explains the bioelectric layer that coordinates cells to build organs and bodies, showing footage of two-headed worms and introducing xenobots. He discusses implications for medicine and the nature of life.

HN commenters use it as the accessible 20-minute entry point to Levin's bioelectricity research whenever regeneration or cell signaling comes up.

your cells are sensitive to charge in general - cells attempt to maintain certain voltage differentials across their membranes via ion channels in the cell membrane, can communicate voltage information with each other via gap junctions, etc. That electrical communication does control how cells behave. If you have 20 minutes to watch this ted talk interview I highly recommend it. My mind was blown. Your DNA determines the hardware, but there's a lot of non chemical communication that goes on between cells that determine how they behave. ▶ this video Once you realize that cells can effectively communicate with each other via voltage, things like whats described about electrical bandages become less surprising.

Electric potential across other cells and also single-cell organisms is well known and not new. This is new though (and revolutionary): ▶ this video Regarding consciousness, I don't get why people who submit to consciousness being everywhere in the universe have problem with simply calling it the universe. It seems to make discussions much more productive.

The article and the comments remind me of Michael Levin's work on bioelectricity. 20 min ted talk - ▶ this video 3 hr lex fridman episode - link

@farkanoid2023-10 · in “Bioelectricity could regrow limbs and organs”

There's a fascinating (in my opinion) TED talk about this featuring the same Biologist, with examples of regenerative experiments performed using Flatworms: ▶ this video

Maybe the neurons are the hardware layer. The software is represented by the electronic activity. There is a good video ▶ this video about this topic.
