    Street grit is the probable source of lead in urban homes, and flaking paint from overpasses and bridges is a major contributor.

  7. Chemistry

    Drinking increases skin’s permeability

    Drinking alcohol can greatly compromise the skin's barrier to chemicals.

  8. Nonstick chemicals upset behavior

    A study in mice finds that early-life exposure to the fluorinated chemicals used in nonstick products can rewire the brain in ways that dramatically affect behavior.

    Letters from the March 25, 2006, issue of Science News

    Bee movie? In the article about using harmonic reflected signals to track bees (“The Trouble with Chasing a Bee,” SN: 1/14/06, p. 23), I thought it was interesting to note that the original technology was created by the Russians as a spy device. The technology is still being used for a form of spying. Dwight […]
