    Stuff gets stiffed by unstiff inserts

    In an odd twist, material that is so extremely yielding that it is said to have negative stiffness will make already stiff materials even stiffer when it's blended into them.

    Novel fuel cell gets hot, but not by a lot

    A new type of fuel cell that works above the boiling point of water—but not too much above it—may lead to improved nonpolluting power sources suitable for cars and portable electronic gadgets.

    Oceans of Electricity

    The world's first commercial wave-power plant began pumping current into a Scottish island's electric grid last winter, just ahead of a host of competing schemes for converting ocean-wave motion into electricity.

    Hop . . . Hop . . . Hopbots!

    Two prototype jumping robots that hop, crash-and-land, and then hop again are demonstrating a novel mobility concept that may finally enable small, cheap robots to roam widely over rough terrain.
