Magnetic Bit Boost: Quantum rewiring for computer memories
A quantum-mechanical memory component that might replace electronic computer memories has come closer to practicality.
- Tech
Ink-jet dots form transistor spots
A new technique makes ink-jet printing of transistor circuits possible from conductive polymer inks.
- Tech
Lighthearted Transistor: Electronic workhorse moonlights as laser
A versatile new transistor amplifies electricity and emits a laser beam.
- Tech
Smashing the Microscope: Tiny crashes harnessed for nanoconstruction
A new technique supplies loose atoms for nanoscale experiments by using the tip of a scanning tunneling microscope to gouge out craters from a surface.
- Tech
Laser Landmark: Silicon device spans technology gap
By coaxing a silicon microstructure into acting as a laser, engineers have achieved a long-sought and important step toward microchips capable of simultaneously manipulating electrons and light.
- Tech
Wee wires that can crawl
Self-propelled strands of a muscle protein coated with gold offer a way to arrange and control the nanoworld.

Tracing the origin of Genesis’ crash
The upside-down installation of four switches intended to signal the Genesis spacecraft to open its parachutes is the likely cause of the craft's crash in the Utah desert on Sept. 8.
- Tech
Tiny tubes could ease eavesdropping
A team of researchers is developing highly sensitive acoustic sensors using ordered arrays of carbon nanotubes, which act much like the rodlike stereocilia of the inner ear.
