  • Reintroduced beavers branching out in San Pedro
    Sunday, May 20, 2012

    Aquatic rodents might not instantly pop to mind when you think of Southern Arizona wildlife - but they're thriving this spring along the San Pedro River near Sierra Vista.

    We're talking beavers - those dam-building, tail-slapping mega-rodents more often associated with mountain streams than arid-region rivers.

    "Beavers are doing really well right now on the San Pedro," said Marcia Radke, a wildlife biologist with the U.S. Bureau of Land Management. "We...

  • Law will require carmakers to make some vehicles noisier
    Wednesday, May 16, 2012

    Forget gas mileage: The most striking aspect of the new Ford Focus Electric is what it doesn't have. "Battery-powered cars are intrinsically quiet, the motor sound falling between a whir and a whisper," marvels a New York Times review of the car. "But the Focus is deep-space silent, the quietest of the many electric cars I've driven."

    And that, it turns out, is a problem.

    Due to the Pedestrian Safety Act of 2010, by this summer the National Highway...
