    In some ways, a single cell is more like an entire artificial neural network.

    Real neurons have some amazing properties that individual neurons in ANNs do not. It's still unclear how we can exploit those properties to improve AI.

      Fascinating.

      I totally see the CheY as an intermediary layer that learned how the changes in attractant must affect mechanical activation.

      A single cell is a living and breathing (respirating) ecosystem.

      DNA, the molecule and associated enzymes, is a computer in and of itself. Every dimension - from its hydration to dimensional folding - is a computational manifold.

      The cell itself is a system of distributed supercomputers, a machine assembly factory, a dizzying highway and information network, and a universe. Replete with defenses, power factories, intricate and robust signal processing, and self destruct mechanisms.

        DNA is not a computer. It's a passive storage mechanism. When you add the appropriate enzymes though it is turing complete.

      Aren’t there efforts to simulate neurons? (Aka artificial brains)
      • dekhn 48 minutes ago
        yes, but I think they are egregiously wasteful of resources if your goal is to recapitulate the behavior of real neurons. Instead you can probably build a far simpler model that produces all the behaviors you want without directly simulating a neuron.

    Of possible interest is John T. Bonner's book The Evolution of Culture in Animals

    Beautiful website.

    It's an amazing design. Did we look at this to create the electric motor?

      No. They were observed in the 1800s, but the structure and mechanism were not elucidated until around 1970 https://www.nature.com/articles/245380a0 It was a big surprise to see elements that greatly resembled existing motors (stator, rotor, etc) and in fact was one of the things that inspired the concept of intelligent design (even though, we believe instead that it evolved spontaneously)

      While biology has inspired many inventions, the electric motor is not one of them. Electric motors were invented in the mid 19th century, before cells were known to be anything more than simple blobs of protoplasm, barely distinguishable under a microscope. It wasn't until high powered microscopes were invented that biologists had any clue to the previously unthinkable complexity of cellular life.

      Wow you weren't kidding. It is really well done.

    It would be mistake to assume that something which appears to be a single cell is a separate from its environment. Space connects all things and if Space happens to be awareness / consciousness then intelligence would be everywhere affecting all things.

      The line between quackery and atomic science is so thin it is a bit cuckoo.
