Well, it isn't so much from Mars as it is from England. The University of Reading, to be exact. That is where scientists have been able to use 300,000 neurons from a rat's brain to control a small robotic vehicle. After separating the neurons from each other and transplanting them into what I assume was an old jug filled with brain food, the researchers found the neurons were forming new connections with each other. They then connected the brain cells to sensors on a robot and presto changeo, the rat brian cells were able to help direct the robot to avoid obstacles. Don't believe me?
