    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...

    PCBs may impair fertility

    PCB exposure may interfere with a woman’s ability to get pregnant, a new study of women undergoing in vitro fertilization suggests. The study of 765 women found that those whose blood contained the highest levels of a particular form of polychlorinated biphenyl — one known as PCB 153 — were 41 percent less likely to give birth than women with the lowest levels.

    One contributing factor...

    Salmonella seeks sweets

    Salmonella enterica, a major food-poisoning germ, can enter the tissues of fresh lettuce where no amount of surface washing will evict it. The scientists who reported that finding earlier this year now think that they've gotten to the root of the issue.

    To model salmonella soil contamination from livestock wastes, the researchers seeded sterile manure with one of three toxic strains of...

    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...

    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...

    Alaskan coral beds get new protection

    Huge tracts of delicate coral gardens and soft-coral forests off the coast of Alaska will be permanently protected from fishing gear that targets groundfish and shellfish by scraping the seafloor.

    Most of the affected sites have never been disturbed by this gear. The National Oceanic and Atmospheric Administration (NOAA) on June 28 announced its new rule to preserve that...

    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...

    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...

    Feds pull approval of poultry antibiotic

    The Food and Drug Administration is about to prohibit poultry farmers from treating chickens and turkeys with the antibiotic enrofloxacin. Use of the antibiotic, whose trade name is Baytril, is leading to the emergence of microbes in the birds' meat that resist several antibiotics used to treat food poisoning in people, the agency says.

    On the market for 9 years, the drug has become...

    The Case of the Suspicious Hamsters

    Mention Salmonella and most people think of chickens and eggs. Indeed, some 118,000 cases of food poisoning each year in the United States trace to consumption of undercooked eggs contaminated with these bacteria. Scores more people contract the foodborne disease from handling or eating undercooked chicken.

    However, barnyard fowl are far from the only animals that transmit Salmonella....
