...report also rejects the idea that Harvard teaching could be improved by creating a “dual tenure-track system” in which some faculty are appointed for research achievements and others for classroom ability...
Daniel is now engrossed in watching video clips of a red toy train on a circular track. The train disappears into a tunnel and emerges on the other side. A hidden device above the screen is tracking Daniel's eyes as they follow the train and measuring the diameter of his pupils 50 times a second. As the child gets bored--or "habituated," as psychologists call the process--his attention level steadily drops. But it picks up a little whenever some novelty is introduced. The train might be green, or it might be blue. And sometimes an impossible thing happens...
...imaging (fMRI) tube while he measured their brain activity during various mental states. For comparison, he used undergraduates who had had no experience with meditation but got a crash course in the basic techniques.

Saplings and wind-sown grasses sprouted in rail beds where the homeless built campfires at night. Whole stretches made you think of the Appian Way after the fall of the Roman Empire, the almost phosphorescent decrepitude of a vanished civilization made even stranger by the fact that an intact, modern...
