    No Peanuts for Your Peanut

    Peanuts are a protein-rich snack food packing plenty of vitamins and trace nutrients. However, these legumes can elicit potentially life-threatening immune reactions within the one in 100 American adults who are allergic to them. Rates of peanut allergy are even higher among children. And the really disturbing news: A new study finds that the age at which this common food allergy first shows...

    Organic Dairying Is on Upswing, But No Panacea

    This is part two of a two-part series on the economics of dairy farming. Part I: "Cow Power," is available at Cow Power.

    For 20 years, Steve Getz worked in the computer industry. Because he traveled a lot, "I came to hate airports and sitting on planes," he says. To ground himself on days off, Steve and his wife, Karen Getz, began dabbling in farming.

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    Caffeinated Liver Defense

    What you drink may greatly affect your vulnerability to potentially life-threatening liver disease, a new study finds.

    The liver, the body's largest solid organ, is a metabolic workhorse. It not only makes a host of proteins and blood-clotting factors, but also synthesizes and helps break down fats, secretes a substance that helps the body absorb fat and fat-soluble vitamins, and...

    Fruits and Veggies Limit Inflammatory Protein (with recipe)

    Over the past few years, many studies have linked an increased risk of debilitating illness—such as heart disease or diabetes—with chronically elevated blood concentrations of a protein typically associated with inflammation. In many cases, people with the indicated illnesses didn't even have a particularly level of inflammation. The good news: A new trial finds that eating plenty of fruits...

    Food Colorings

    Crop geneticist Charles R. Brown has spent a decade working to make a better potato. In the beginning, he focused on beefing up the familiar white-fleshed tuber. His strategy was to recapture healthful traits from old-style spuds from the plant's native range in South America. He examined many yellow, red, and purple potatoes, none of which grows well in a U.S. climate. While cross breeding...

    Frozen Assets

    Ninety percent of the nation's dairy cows—some 8.2 million animals—belong to a single breed: Holstein. Owing to the dairy industry's extensive reliance on artificial insemination using semen from only the choicest bulls, this Holstein population is heavily inbred. "Today, it's as if there were only about 35 unrelated cows [contributing genes to] our national Holstein herd," explains...

    Extreme Impersonations

    Extreme physical conditions have a way of bringing out the strangest behaviors that nature can muster. Just ask physicist John E. Thomas. Two years ago, he and his colleagues at Duke University in Durham, N.C., were working with intense lasers in a high-vacuum chamber at temperatures next to absolute zero. They were manipulating tiny clouds of lithium gas. When the scientists turned off the...

    Infectious stowaways

    While in port, shipping vessels often suck huge quantities of water into their ballast tanks to replace the stabilizing weight of cargo they've off-loaded. Along with this water comes abundant aquatic life, such as mussels and crabs, which journey with the ships—often crossing entire oceans—until the ballast is dumped in preparation for loading new goods.

    Largely ignored in this lively...

    Calculating Swarms

    The frenetic scurrying of ants around a nest may seem like much ado about nothing. There's method in their madness, however.

    All this activity adds up to ingenious strategies for collectively working out the shortest path to a food source, combining forces to move a large, unwieldy object, and performing other functions crucial to an ant colony's well-being.
