    Rural ozone can be fed by feed (as in silage)

    Livestock operations take a lot of flak for polluting. Researchers are now linking ozone to livestock, at least in one of the nation's most agriculturally intense centers. And here the pollution source is not what comes out the back end of an animal but what’s destined to go in the front.

    From movies you’ll love to drugs you’ll take

    A new method picks out promising drug compounds by computer, in much the same way Netflix recommends DVDs to its customers.

    Study reports hints of phthalate threat to boys’ IQs

    You may have a hard time spelling phthalates, but there’s no avoiding them. They’re in the air you breathe, water you drink and foods you eat. And this ubiquity may carry a price, particularly for young boys, emerging data suggest. Including a drop in their IQ.

    Skin as a source of drug pollution

    Traces of over-the-counter and prescription meds taint the environment. The presumption Ì and it's a good one Ì has been that most of these residues come from the urine and solid wastes excreted by treated patients. But in some instances, a leading source of a drug may be skin Ì either because the medicine was applied there or because people sweat it out.

    Mothballs deserve respect

    I don’t use mothballs — except sometimes to sprinkle down the burrows of animals excavating tunnels beneath the deck floor of my pergola. It’s the most effective stop-work order for wildlife that I’ve found. But I won’t use these stinky crystals inside my home because they scare me. And those fears appear justified, according to Linda Hall of the California Environmental Protection Agency.

    Cap or cork, it’s the wine that matters most

    Comparative study finds that screw tops can perform just as well in regulating the aging process.
