Youtube Summary
DNA isn't the only builder in the biological world -- there's also a mysterious bioelectric layer directing cells to work together to grow organs, systems and bodies, says biologist Michael Levin. Sharing unforgettable and groundbreaking footage of two-headed worms, he introduces us to xenobots -- the world's first living robots, created in his lab by cracking the electrical code of cells -- and discusses what this discovery may mean for the future of medicine, the environment and even life itself. (This conversation, hosted by TED's Chris Anderson, was recorded June 2020.)

Electric potential across other cells and also single-cell organisms is well known and not new.

This is new though (and revolutionary): https://www.youtube.com/watch?v=XheAMrS8Q1c

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.

"Something electrical floating around your cells" isn't just the mind either, it's also how the organism coordinates its development: https://www.youtube.com/watch?v=XheAMrS8Q1c

I'd also like to draw attention to his previous appearance on Curt Jaimungal's podcast[0], in which he gives an extremely detailed account of his research. Really fascinating stuff, I wonder what will come out of it.

Regarding how the body "knows" how to form missing pieces, might be worth checking out Michael Levin's research regarding bio-electricity. Most interesting finding to me is that once modified, the animal bodies continue to produce different parts as if there is some electrical "memory" in the cells.

Here is an overview video: https://www.youtube.com/watch?v=XheAMrS8Q1c, though there are much longer lectures and papers which I would recommend if you are interested.

Whenever there's a post about regeneration, I always refer people to this amazing TED talk.
