Scientists Invented AI Made From DNA

Last Wednesday, researchers at Caltech announced that they created an artificial neural network from synthetic DNA that is able to recognize numbers coded in molecules. It's a novel implementation of a classic machine learning test that demonstrates how the very building blocks of life can be harnessed as a computer. This is pretty mind blowing, but what does it all mean? For starters, "artificial intelligence" here doesn't refer to the superhuman AI that is so beloved by Hollywood. Instead, it refers to machine learning, a narrow form of artificial intelligence that is best summarized as the art and science of pattern recognition.
