    Ups and downs in the quest for clean air

    Newly released maps reveal that U.S. air quality has markedly improved over the last decade. The evidence comes from measurements of nitrogen dioxide (NO2 ), a pollutant emitted by vehicles and coal power plants. Yet as the United States cleans up, rapidly industrializing cities in Asia, the Middle East and Africa are spewing more and more of the yellow-brown gas.

    A mathematician once posed a deceptively simple question. Can a single 2-D conveyor belt be stretched around a set of wheels such that the belt is taut and touches every wheel without crossing itself?

    MIT computer scientist Erik Demaine pondered the problem. For just a few wheels, the solution is easy: Arrange four into a square, wrap the belt around the outside, and...

    Music soothes the aging brain in film ‘Alive Inside’

    Some of the most potent medicine doesn’t come in a paper cup or a little pill. Instead, it pours from a cheap set of headphones. As chronicled in Alive Inside, music has the power to awaken long-dormant memories and emotions in people suffering from Alzheimer’s and other disorders.
