    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.

    Walnuts slow prostate cancer growth

    SAN FRANCISCO A new study suggests that mice with prostate tumors should say “nuts to cancer.” Paul Davis of the University of California, Davis, hopes follow-up data by his team and others will one day justify men saying the same.

    For years, this nutritionist had been studying heart benefits of walnuts. Most nuts – in sensible quantities – can benefit the heart. But among...

    Power from heat

    The thermoelectric effect can produce small amounts of electricity from almost any source of heat, but its low efficiency has so far limited its uses. A team has now found a simple way to make one thermoelectric alloy more efficient.

    When two ends of a stick of a thermoelectric material are exposed to different temperatures, a voltage appears. The electrons in the stick act like the...

    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...

    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...

    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.

    Persistent Prions: Soilbound agents are more potent

    Deformed proteins called prions cause fatal brain-destroying disorders, such as chronic wasting disease in deer and elk and mad cow disease, which can infect people. Evidence suggests that prions make their way into animals' nervous systems through ingestion, but scientists aren't sure.

    A new study shows that prions become more infectious when they latch on to soil particles that...
