    Nurturing Our Microbes

    Each of us is a metropolis. Bustling about in everyone's body are tens of trillions of microbes. Some are descended from starter populations provided by mom during birth. Additional bacteria, yeasts, and other life forms hitchhike in with foods. By age 3, everyone's gut hosts a fairly stable, yet diverse, ecosystem.

    Most of the tiny stowaways hide out in the...

    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.

    Lettuce Liability

    Little more than a year ago, supermarkets from coast to coast stripped fresh spinach from produce aisles as a food-poisoning outbreak swept the nation. From mid-August through September 2006, virulent bacterial infections sickened at least 204 spinach consumers. Five died and 30 others suffered acute kidney failure.

    Among more than 3,500 genetically unique...

    A dilute stream of prescription drugs flows through the nation's rivers. To help cut that flow, representatives of the federal government and a pharmacists' trade group want consumers to stop flushing most old drugs down the toilet.

    Mafia Cowbirds: Do they muscle birds that don't play ball?

    Cowbirds in Illinois that sneak their eggs into other birds' nests retaliate violently if their scam gets foiled, researchers say.

    The brown-headed cowbirds of North America outsource nest building and chick raising. Female cowbirds dart into other birds' nests, quickly lay eggs, and rush away. The nest owners are left to care for big, demanding cowbird chicks.

    Happy fish?

    Researchers have detected antidepressant drugs in the brains of fish captured downstream of sewage-treatment plants.

    Pharmaceuticals taint waterways because people excrete many of the drugs they take but treatment plants don't extract all the chemicals (SN: 4/1/00, p. 212: More Waters Test Positive for Drugs). Concerned that antidepressants might be accumulating in fish, Melissa M....

    Birds Don't Have to Be So Hot

    Last week, Iowa State University issued a news release about how long it takes to cook a turkey if you place it into the oven frozen. The answer: 5.5 hours for a 13- to 15-pound bird cooked in a 325°F oven.

    However, what really caught my attention was something a little lower in the release—that the U.S. Department of Agriculture had issued a statement earlier this year...

    Cola May Weaken Women's Bones

    Middle age and older women may want to limit their consumption of cola-flavored soft drinks. A new study links regular consumption of these beverages with reduced mineral density of hip bones in women past menopause. No similar hip vulnerability to cola showed up in men of the same age.

    The gender-specific finding was quite strong, notes Katherine L. Tucker of the Jean Mayer USDA...

    Messiness Rules: In high dimensions, disorder packs tightest

    Should you find yourself with a 60-dimensional suitcase, the best way to pack it may be the easiest: Throw in everything in a jumble. That's the way to fit the most high-dimensional spheres into a fixed space, new research suggests.

    The finding may be useful even to people without extra-dimensional luggage. It may improve the design of mathematical procedures called error-...

    Social jet lag: Need a smoke?

    From Munich, at the Euroscience Open Forum meeting

    People who have a hard time waking in the morning because their bodies' internal clocks are out of sync with their sleep schedules are said to have "social jet lag." Researchers in Europe have determined that the phenomenon strongly correlates with smoking.
