Making music on a microscopic scale

Strings a fraction of the thickness of a human hair, with microscopic weights to pluck them: researchers and students from the MESA+ Institute for Nanotechnology of the University of Twente in The Netherlands have succeeded in constructing the first musical instrument with dimensions measured in mere micrometres - a 'micronium' - that produces audible tones.

Semiconductor could turn heat into computing power

Computers might one day recycle part of their own waste heat, using a material being studied by researchers at Ohio State University. The material is a semiconductor called gallium manganese arsenide. The researchers describe the detection of an effect that converts heat into a quantum mechanical phenomenon - known as spin - in a semiconductor.

Solar cells thinner than wavelengths of light hold huge power potential

Ultra-thin solar cells can absorb sunlight more efficiently than the thicker, more expensive-to-make silicon cells used today, because light behaves differently at scales around a nanometer (a billionth of a meter), say Stanford engineers. They calculate that by properly configuring the thicknesses of several thin layers of films, an organic polymer thin film could absorb as much as 10 times more energy from sunlight than was thought possible.

Nanoneedle delivers quantum dots to cell nucleus

Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell's nucleus.
