Electromagnetism acts oddly in device
Without breaking any physical laws, a novel, fiberglass-copper structure affects microwaves so strangely that a beam of radiation passing through it bends at an angle opposite from what it get bent at an angle opposite from what it would have exiting any other known material.

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.
