Scientists have created an AI inside a test tube using strands of DNA

An artificial neural network that's made entirely from DNA and mimics the way the brain works has been created by scientists in the lab. The test tube artificial intelligence can solve a classic machine learning problem by correctly identifying handwritten numbers. The work is a significant step in demonstrating the ability to program AI into man-made organic circuits, scientists claim. This could one day lead to human-like robots made from entirely organic materials, rather than the shiny metal cybermen seen in popular culture. Researchers hope the device will soon start forming its own'memories', from examples added to the test tube.
