    How resveratrol (in grapes, peanuts and wine) fights fat and disease

    Resveratrol, a constituent of grapes, peanuts and certain other plants, can fight the proliferation of fat cells and improve the uptake of sugar from the blood, a pair of new studies show. Their findings suggest mechanisms to explain why grape products, including wine, have developed a reputation as heart healthy, obesity-fighting and beneficial for people developing diabetes.

    Fabulon: Looking less fabulous

    Researchers have tentatively linked polychlorinated biphenyls (PCBs) in people—and their dwellings—with Fabulon, a product used throughout the late 1950s and 1960s as a durable top coat for hardwood floors.

    During a survey of 120 homes on Cape Cod, Mass., researchers found two houses with unusually high PCB concentrations in air and house dust. Residents in both homes remembered a...

    Escaping flatland

    From Washington, D.C., at a meeting of the American Society for Cell Biology

    Nothing is more iconic of biological research than the petri dish. Yet the idea that growing cells in a flat dish can sometimes lead scientists astray is gaining traction.

    As an alternative, some researchers are experimenting on cells grown in gelatinous materials made from many of the same structural...

    Biohazard: Smoking before or after pregnancy may harm daughters' fertility

    Exposing female mice to chemicals found in cigarette smoke before pregnancy or during the period in which they nurse their young impairs the reproductive capacity of their female offspring, a new study finds.

    Many women stop smoking when they discover they are pregnant, aware that this habit endangers the baby. The new data suggest that may not be enough to protect their daughters' long...

    Caffeine Aids Golden Girls' Mental Health

    Although wine may improve with age, the human body tends to falter during the so-called golden years. Among the most exasperating declines occur in memory and critical aspects of reasoning. However, downing plenty of caffeine-rich coffee—or tea—may offer one low-cost solution for keeping aging wits sharp, a French study finds. The rub: This strategy appears to benefit only women.

    A Melon for Dieters and Diabetics

    Mention watermelon and people immediately think of sweet, juicy, crimson-colored fruit. But watermelons didn't start that way, notes Angela R. Davis of the U.S. Agricultural Research Service. Wild watermelons in their native Africa are white fleshed, the size of softballs, and "hard like softballs," she notes. Bitter and anything but sweet, watermelons hardly started as dessert.

    Sour Genes, Yes—Salty Genes, No

    Some people abhor broccoli, complaining about its intensely bitter taste. Others (myself included) find broccoli's flavor interesting and pleasing—decidedly, not bitter. What leads to our differing culinary opinions is the possession of, or lack of, (in my case, evidently) genes conferring a super sensitivity to bitter taste. Science has recognized such genetic differences for at least a...

    Tea—Milking It

    I'm a serious tea drinker. I'll down it hot or cold, plain or with lemon. Like most Americans, however, I don't regularly add milk. But when my colleague David Lindley, an editor here at Science News, was growing up, his family certainly did.

    Being a Brit, David comes from a culture that holds considerable reverence for this brew and might be accused of being fussy about its preparation...

    Want that fiber regular or decaf?

    Researchers in Spain report that a cup of coffee can deliver a significant portion of daily dietary fiber. The drink hadn't been known to contain any fiber.

    Like the cholesterol-lowering substances found in oat bran, fiber in coffee consists of carbohydrates that the body can't digest, but which dissolve in digestive fluids. However, unlike oat bran's soluble fiber, the fibrous...

    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.
