Test Tube DNA Brain Gets Quiz Questions Right

Neuron-SEM-2A step closer to artificial intelligence? Discovery News reports:

A team of researchers lead by Lulu Qian from the California Institute of Technology (Caltech) have for the first developed an artificial neural network — that is, the beginnings of a brain — out of DNA molecules. And when quizzed, the brain answered the questions correctly.

They turned to molecules because they knew that before the neural-based brain evolved, single-celled organisms showed limited forms of intelligence. These microorganisms did not have brains, but instead had molecules that interacted with each other and spurred the creatures to search for food and avoid toxins. The bottom line is that molecules can act like circuits, processing and transmitting information and computing data.

The Caltech used DNA molecules specifically for the experiment, because these molecules interact in specific ways determined by the sequence of their four bases: adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). And what’s more, scientists can encode the sequence into strands of DNA molecules, essentially programming them to function in a predetermined way.

    This is a very interesting development. I just hope they don’t decide to call it “Cyberdyne” or “Mother Brain.”

    This is way beyond my scope of knowledge but it sounds pretty cool. I doubt “Quiz” is in any way a proper term to describe what their doing, I’m assuming they just got the feedback they expected from it and didn’t actually hand it a #2 Pencil.
