At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler.

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes, especially in the 'green gap', simulations have shown. Nanostructure LEDs made from indium nitride could lead to more natural-looking white lighting while avoiding some of the efficiency loss today's LEDs experience at high power.
