This comes by way of UNCOMMON DESCENT, hat-tip to Denyse O’Leary:

• I’ve written about the “electric cell” here and here, describing how electric currents in cell membranes transmit information through an “electric code.” I’ve also written about “water wires” and cable bacteria. Biologists have long known about the membrane potential of an individual cell, which measures about -70 millivolts, due to ionic separations. They have known that neurons transmit ionic voltages down their membranes. Now, recent discoveries are showing that we must expand our exploration of bioelectricity to the whole body. – David Coppedge (March 15, 2023)

TED: 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.)
