    Turning magnetic resonance inside out

    A new method of manipulating magnetic signals makes it possible to gather useful information about a chemical sample—or perhaps one day a person—without often-claustrophobic confinement inside a magnetic coil.

    Insects in the wind lead to less power

    A previously puzzling pattern of power loss in wind turbines results from coatings of insects that were smashed by the blades during low winds.

    Carbon nanotubes show superconductivity

    Researchers have made individual superconductive carbon nanotubes that are just 0.4 nanometer wide.

    Ground-based telescope detects star’s corona

    Astronomers using a ground-based telescope have for the first time observed near-ultraviolet light from the corona of a star other than our sun.

    Study picks new site for dinosaur nostrils

    A new analysis of fossils and living animals suggests that most dinosaurs' nostrils occurred at locations toward the tip of their snout rather than farther up on their face, a concept that may change scientists' views of the animals' physiology and behavior.

    Roach gals get less choosy as time goes by

    As their first reproductive peak wanes, female cockroaches become more like male ones, willing to mate with any potential partner that moves.

    Busting the Gut Busters

    Scientists are uncovering a cache of specialized weaponry used by bacteria that can spear holes in the intestine, perforate it, force it to change shape, and then spew toxins that attack other organs.

    Soaking Up Rays

    Although light shines through body parts of a primitive marine sponge much as it does through sophisticated optical fibers for telecommunications, scientists differ on whether sponges hold clues to better fibers for humankind.
