    Having your children live near a busy highway is kind of like keeping them penned in the smoking area of a Greyhound bus station, according to a new study. European researchers applied a statistical technique known as "population-attributable fractions" to existing data to root out how much childhood asthma can be blamed on heavy traffic. Their conclusion: 14 percent of chronic asthma in kids is caused by car exhaust, which falls into the 4 to 18 percent bracket of childhood asthma cases resulting from exposure to second-hand smoke, as per World Health Organization estimates.

  • Bullet trains fuel real-estate booms, improve quality of life and create other unintended consequences by sharply reducing commute times from smaller cities to large megacities, economists from UCLA and China's Tsinghua University observed in a new study in China. A similar dynamic, they said, could play out as California builds its own high-speed rail system.
