Actually, they were using the robotic arms to eat bits of banana and marshmallows (the monkeys, not the scientists). According to the New Scientist: “The feat marks the first time a brain-controlled prosthetic limb has been wielded to perform a practical task.”
The rhesus monkeys were trained to use the arms with a joystick, and then their arms were restrained and they had to use their brains to control the devices. One of the monkeys was successful 61 percent of the time, and would often reach for another treat while he was chewing on the one he just got. (And with a 39 percent failure rate, I can see why. Poor little bugger was probably starving — not to mention a complete lack of protein in his diet.)

Getting us closer to the pirate singularity. (Pictured at right.)
