    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...

    Dashing Rogues

    In February 1933, the Navy tanker USS Ramapo was steaming its way from the Philippines to San Diego in the midst of an exceptionally strong storm. The 146-meter-long ship was buffeted by near-hurricane–force winds. Early on the morning of Feb. 7, a wave far larger than the others surrounding the ship overtook the Ramapo from behind.

    As the stern of the ship dropped...

    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...

    Carcinogens in the Diet

    It's official. The federal government now has added agents commonly found in overcooked meat to the list of potential cancer causers.

    On Jan. 31, the National Toxicology Program (NTP), part of the National Institutes of Health, published its latest update of materials known to cause cancer in people and others that are "reasonably anticipated" to do so. Among the 246 agents on...

    Botany under the Mistletoe

    A holiday merrymaker loitering under the mistletoe may not be thinking much about parasitic plants. That's a loss, because the world's mistletologists are making wondrous findings about the more than 1,300 species they study.

    Some of the plants have flowers with trick openings. Some shoot their seeds farther than most watermelon spitters can spout. Some...

    An early cosmic wallop for life on Earth?

    Life on Earth either started with a bang or it suffered an unusually rocky childhood, a new study suggests.

    Analyzing lunar meteorites, researchers have found new evidence that a swarm of debris bombarded the moon some 3.9 billion years ago. That's about the same time that life may have formed on Earth. If our planet suffered a similarly catastrophic bombardment, as scientists...

    Lava Life: Hints of microbes in ancient ocean rocks

    Samples of lava that erupted onto the ocean floor almost 3.5 billion years ago contain microscopic tubes that may have been created by microbes, researchers say. That scenario puts these structures among the oldest known physical remnants of life.

    When lava oozes out at midocean ridges where Earth's tectonic plates spread apart, water quickly chills the molten material as it...

    Leaden Gardens

    Soils in many cities of the United States carry a poisonous legacy: heavy concentrations of lead. The metal was deposited for years as fallout from flaking leaded house paint and the emissions of cars burning leaded gasoline. Recognizing the threat posed by tainted soil, environmental scientists have warned that growing edible plants in soils near streets or within several feet of homes and...

    Mosquito Magnets

    Ah, summer nights! The heat and humidity mingle with the sweet scent of citronella candles, the blue glow of a bug zapper, and the sticky feel of mosquito repellent. Some unfortunate people need this entire antimosquito arsenal to avoid getting eaten alive, while others hardly attract the pesky creatures at all.

    Scientists have known for decades that...

    Water for the Rock

    More than 4.5 billion years ago, the sun and its planets were taking shape from a rotating disk of ice, gas, and dust. This protosolar nebula was hotter and denser toward its center and cooler and less dense farther out. These gradients profoundly influenced the chemical composition of different regions of the early solar system, including the distribution of water. Close to the nebula's...
