kkleiner writes "In an experiment that might seem like something only a mad scientist would conjure, researchers injected human brain cells into the brains of mice to see how it would affect the way the mice thought. It did: the mice got smarter. But the cognition boosting cells weren’t neurons, they were the red-headed step-children of neuroscience called astrocytes. The study turns on its head the role historically attributed to astrocytes of simply supporting the all important function of neurons without playing a significant role in how we learn and think."

discoveries, is not "Eureka!" (I found it!) but "That's funny ..."
