  • Atrazine: I just saw this link from August about the pesticide atrazine, and learned it’s the most common contaminant in U.S. drinking water. And, of course, one of the most common pesticides. There’s a call for a review of the product, which isn’t good news for corn growers. It’s good news for frogs, however. Scientists discovered long ago how minute amounts of atrazine could cause feminization of frogs:

    Now, new research suggests that atrazine may be dangerous at lower concentrations than previously thought. Recent studies suggest that, even at concentrations meeting current federal standards, the chemical may be associated with birth defects, low birth weights and menstrual problems.

  • Wet thoughts: Are you the type who does a lot of thinking in the shower? You can’t just write down your idea by using the steamy shower door. You need one of these.
