Researchers at Northwestern University have developed an AI-designed drone that spins fast enough to fool the human eye, making it appear almost invisible. The single-propeller drone rotates around 25 times per second, while tests found it is around 10 times less visible than conventional drones. Scientists say AI was used to test thousands of designs before arriving at the final model.
