    Bumblebee 007: Bees can spy on others' flower choices

    In a novel test of insect intel, researchers observed that bumblebees, which had spied on a worker bee from another colony feasting on unusual flowers, later tended to visit flowers of the same color.

    This talent amounts to social learning, which is picking up a new behavior from observations of another animal, say the test's designers, Bradley D. Worden and Daniel R. Papaj...

    A New Role for Statin Drugs? Cholesterol fighters may reduce deaths soon after heart attacks

    People brought to a hospital in the throes of a heart attack are more likely to survive if they receive a statin drug, a new study finds. The report could pave the way for a trial to ascertain whether doctors should routinely use the cholesterol-lowering agents to stabilize these heart patients.

    Guidelines for physicians recommend prescribing statins to hospitalized heart attack...

    Wings warp for birdlike agility

    Taking cues from seagulls, a bird-size prototype aircraft morphs its wings to navigate cluttered environments. The ability to shift its wings between an M shape for cruising and landing and a W shape for dives and turns bodes well for tasks in tight spots, from tracking wildlife in canyons to spying on an urban enemy, says Mujahid Abdulrahim of the University of Florida in Gainesville.

    Class Acts from New Pesticides: Chemicals have little effect on mammals

    Insects, be warned. Research on three continents has turned up two new classes of selective pesticides that immobilize and eventually kill many insect species by interfering with a cell receptor unique to the insects. The novel chemicals could potentially prevent infestations of crops while posing minimal danger to noninsects.

    "Both classes of chemicals act at the ryanodine receptor,"...

    Fog Be Gone: Nanocoating clarifies the view

    A new coating that prevents fogging and reflection could one day clear the world of misty mirrors, glaring glasses, and cloudy camera lenses. Researchers described their innovation, which relies on porous layers of nanoscale particles, at the American Chemical Society's meeting this week in Washington, D.C.

    Fogging occurs when water droplets from moist air condense on a cool...
