    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...

    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...

    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...

    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...

    Infectious Foie Gras?

    Amyloid, a term for a misfolded form of an otherwise normal protein, is most often associated with amyloid-beta, the waxy protein that builds up in the brains of people with Alzheimer's disease. But at least 20 other kinds of amyloid, each derived from a different protein, can crop up in various parts of the body. What such malformed proteins have in common is their hairlike shape and...

    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...

    Fish Killer Caught? Ephemeral Pfiesteria compound surfaces

    A team of researchers claims to have found an elusive algal toxin implicated in massive fish kills along the Mid-Atlantic coast in the 1990s. They say that the compound's characteristics explain why it has been so difficult to track down. Other researchers, however, remain skeptical.

    The hunt for a toxic product of the single-celled alga Pfiesteria piscicida dates to the early...

    Counterintuitive Toxicity

    For decades, researchers largely assumed that a poison's effects increase as the dose rises and diminish as it falls. However, scientists are increasingly documenting unexpected effects—sometimes disproportionately adverse, sometimes beneficial—at extremely low doses of radiation and toxic chemicals.

    Consider the environmentally ubiquitous plastic-softening agent, di-2-ethylhexyl...
