    The Power of D

    A nutritional supplement that is free of charge, offers a wide range of health benefits and poses little risk sounds like fodder for a late-night TV commercial. But proponents of vitamin D are increasingly convinced that the sunshine vitamin delivers the goods, no strings attached.

    It offers a safe route to better health, these advocates say, by...

    Big Fishing Yields Small Fish

    Sharks, billfish, cod, tuna and other fish-eating fish — the sea’s equivalents to lions on the Serengeti — dominated the marine world as recently as four decades ago. They culled sick, lame and old animals and kept populations of marine herbivores in check, preventing marine analogs of antelopes from overgrazing their environment.

    But the reign of large predators now...

    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...

    Now This Is Depressing . . .

    People who increased their fish consumption to brighten their outlook on life may want to consider alternative strategies. A new review of published studies on the effects of long-chain omega-3 fats—the type found in fish oils—finds "little support" that they "improve depressed mood." However, that's no reason to give up eating fish. Their fats have been linked to a host of health benefits,...

    Are pollutants shrinking polar bear gonads?

    The more polluted a polar bear's fat, the more likely its reproductive organs will be undersize, scientists find.

    They collected gonads from 55 male and 44 female bears killed legally by subsistence hunters in east Greenland. The scientists then tested the bears' fat for pollutants that might affect sex hormones.

    Especially in immature males, testis length diminished with...

    Prescription Strength Chocolate, Revisited

    For roughly a decade, science-savvy chocolate consumers have taken comfort from a string of studies suggesting that their sweet and usually high-fat vice has a potential up side. The most reassuring news was that the antioxidant flavonoids abundant in dark chocolate appear to reduce blood pressure and perhaps protect people from dangerous blood clots.

    At the Cocoa Symposium,...

    Caffeinated Liver Defense

    What you drink may greatly affect your vulnerability to potentially life-threatening liver disease, a new study finds.

    The liver, the body's largest solid organ, is a metabolic workhorse. It not only makes a host of proteins and blood-clotting factors, but also synthesizes and helps break down fats, secretes a substance that helps the body absorb fat and fat-soluble vitamins, and...

    How 'Green' Is Home Cooking?

    Which is better for the environment: a meal cooked from scratch at home or a packaged frozen or freeze-dried meal cooked up in distant industrial kitchens and trucked to supermarkets? Most consumers would guess the former, notes environmental engineer Ulf Sonesson. Even many food scientists would vote for home cooking as the greener option, he says.

    However, those guesses...

    Vitamin Boost

    First in a two-part series. Part II: "Vitamin D: What's Enough?" is available at Vitamin D: What's Enough?.

    The story of vitamin D would appear simple. Take in enough sun or drink enough fortified milk to get the recommended daily amount, and you'll have strong bones. Take a supplement, if you want insurance. But recent studies from around the world have revealed that the...

    Don't Let the Bugs Bite

    Celia Cordón-Rosales wants to build a ghost town. A dozen small thatch and adobe huts would stand in several clusters. A few pigs would occupy nearby pens, insects would buzz to and fro, and bacteria would live out unremarkable lives. But the mock hamlet would be devoid of human residents. It would also be enclosed in nets of mesh so fine that nothing as large as a bug could escape. And a...
