    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...

    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.

    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...

    Chocolate Constituent Bests Fluoride

    "Chocolate Toothpaste? Extract of Tasty Treat Could Fight Tooth Decay."

    That's how Tulane University's news office provocatively titled a press release it issued last week. Sound sweet? Unfortunately, it's anything but. The extract, theobromine, is a bitter constituent of a number of plants, including the beans used to make chocolate. A chemical cousin to caffeine, this...

    A smart pill for seniors?

    From Washington, D.C., at the Experimental Biology 2007 Conference

    Many people approaching retirement age find that memories fade and quick-wittedness flags. Scientists at the University of Massachusetts in Lowell have formulated what they call a "smart pill" to optimize brain health in such people. In pilot trials, its combination of dietary supplements boosted performance on simple...

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    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...

    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...

    Killer Findings: Scientists piece together 1918-flu virus

    The "Spanish" flu killed an estimated 20 million to 50 million people worldwide between 1918 and 1919. Hoping to prevent such a deadly outbreak from recurring, scientists have long strived to figure out what characteristics differentiate that strain from other, more-benign varieties. Because researchers have lacked live samples of the killer virus, however, they couldn't answer this pivotal...
