Computer maker HP plans to release a 3-D printer—but that doesn’t necessarily mean a personal printing revolution is afoot.
"Capillary charges", which act like magnetic poles on the surface of liquids, can pull millimetre-sized building blocks together, a technique that promises a new era of mesoscopic-scale manufacturing.
Cheap, simple water filters made of plant xylem could dramatically reduce the incidence of water-borne diseases in places without access to clean drinking water, say engineers.
If you thought a blob of oil is a good-for-nothing, useless, errr, blob, here's a video that will make you think again.
Magnetic hard discs can store data for little more than a decade. But nanotechnologists have now designed and built a disk that can store data for a million years or more.
The world's fastest thermal transistor could lead to thermal logic gates for controlling microscopic machines, say physicists
New research suggests graphene could enable highly efficient optical communication in chips for data centers and supercomputers.
German researchers have designed, built, and tested the first metamaterial made out of superconducting quantum resonators.
A carbon nanotube computer processor is comparable to a chip from the early 1970s, and may be the first step beyond silicon electronics.
Theorists have discovered a new optical force that is analogous to the thrust that keeps aircraft aloft and causes tennis balls to swerve.
