    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...

    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...

    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...

    Easy Answers: Quantum computer gives results without running

    Physicists have long known that quantum computers have the potential to race through calculations trillions of times as fast as ordinary computers do. Now, it seems that those machines may not have to calculate at all to deliver answers.

    That seemingly absurd possibility, which was advanced as a theory several years ago, has now received experimental verification. What's more, although...

    Fooling the Satiety Meter (with recipe)

    Want to lose weight without counting calories? A new study finds that the easiest strategy might be reducing a meal's energy density—calories per ounce of food. When volunteers were offered such density-diminished meals, they rated the fare as filling—and as palatable—as they had full-calorie versions of the same foods.

    Smaller portions also curbed how much someone...

    Prions' dirty little secret

    Fifteen years ago, scientists at the National Institutes of Health reported that malformed prions—proteins that can trigger lethal illnesses including mad cow disease—remain on soil surfaces for at least 3 years. Now, scientists report why rain doesn't flush away the prions: The proteins bind almost irreversibly to clay.

    In fact, clay can "retain up to its own mass of ... prion proteins...

    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...

    Money Matters in Obesity

    What's the answer to the nation's growing epidemic of obesity? "Get people to eat less and exercise more" might be obvious—but that's easier said than done, say Allen M. Spiegel and Barbara M. Alving of the National Institutes of Health.

    That's why the American Journal of Clinical Nutrition has published the pair's comments, along with those from a host of other...

    Star Wars Goes Organic

    M&M chocolate-candy commercials are among the more entertaining on television. In the latest one, a plain and a peanut M&M character meet with Darth Vader of Star Wars. After a little muscular persuasion by Darth, the M&M guys announce they'll join "the dark side."

    M&M/Mars calls this its first installment in "Chocolate M-pire," an ad...
