    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...

    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...

    Another Way Men and Women Differ

    At least until menopause, women face a lower risk than men do of artery-clogging heart disease. Michigan scientists now turn up one potential reason: before menopause, one of the avenues for clearing meal-derived fats from the blood operates better in women than in men of the same age. This makes the fat less available to the plaque-forming cells in women's arterial walls.

    Reevaluating Eggs' Cholesterol Risks

    Adults are continually bombarded with messages about how eating foods rich in cholesterol can elevate an individual's risks of atherosclerosis and heart attacks. Many such warnings have focused on eggs because their yolks are a major dietary source of cholesterol.

    However, eggs may be getting a bum rap, suggest the findings of a study of middle-aged and elderly volunteers....

    Feminized cod on the high seas

    From Baltimore, at a meeting of the Society of Environmental Toxicology and Chemistry

    Male cod in the open ocean are producing vitellogenin, an egg-yolk protein ordinarily made only by females.

    Vitellogenin "is a highly specific indicator of a fish's exposure to estrogens"—female sex hormones—as well as to pollutants that mimic them, notes Alexander P. Scott of the Centre for...

    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...

    Muck Tech: Natural enzyme displaces precious metal in fuel cell

    Honed by billions of years of evolution, many microbial enzymes are champions at stripping electrons from hydrogen molecules and shunting the charged particles into biochemical reactions. Now, a team of scientists in England and Germany has tapped that molecular machinery to create a new type of fuel cell.

    Like most fuel cells, this one steals electrons from hydrogen molecules...

    Armor-Plated Puzzle

    A few years after Francis H. Crick and James D. Watson unveiled the structure of DNA in 1953, they rocked the fledgling field of molecular biology again with a bold notion: Viruses are, in part, structured as crystals are. That idea captivated Donald L.D. Caspar and Aaron Klug, who then systematically applied what they knew about crystal geometry to classify and predict the structures that...

    Botany under the Mistletoe

    A holiday merrymaker loitering under the mistletoe may not be thinking much about parasitic plants. That's a loss, because the world's mistletologists are making wondrous findings about the more than 1,300 species they study.

    Some of the plants have flowers with trick openings. Some shoot their seeds farther than most watermelon spitters can spout. Some...

    Ink-jet dots form transistor spots

    If microcircuits could be printed with ink instead of being sculpted into silicon, electronic smarts could adorn almost everything. When electronically tagged, even grocery items could, without being scanned, transmit prices to cash registers.

    How about using ink-jet printers to do the job? Loaded with electrically active ink, printers can already make light-emitting diodes (LEDs) for...
