Magnets see the light

Light-sensitive ’plastic’ magnets could replace your hard drive.

A ’plastic’ magnet that responds to light could lead to new ways of storing and reading large amounts of computer data. Light would be used to store information in cheap, fast and high-capacity ’magneto-optic’ memories.

The light-switchable magnet is the first to be made from organic (carbon-based) molecules. This means its discoverers, Arthur Epstein of Ohio State University in Columbus and Joel Miller of the

The next step in quantum computing

A team of physicists in the United States has made an important step towards making quantum computing a reality. Research into a new type of noiseless quantum information bit, or qubit, is published today in the joint Institute of Physics and German Physical Society journal, New Journal of Physics.

At a sub-atomic scale the laws of quantum physics lead to strange new properties of matter. For several years physicists have been trying to exploit this quantum weirdness to build a new type of `

World Wide Web Consortium Issues XML Signature as a W3C Recommendation

Joint work with IETF produces XML-based solution for digital signatures, foundation for Secure Web services

The World Wide Web Consortium (W3C) has issued XML-Signature Syntax and Processing (XML Signature) as a W3C Recommendation, representing cross-industry agreement on an XML-based language for digital signatures. A W3C Recommendation indicates that a specification is stable, contributes to Web interoperability, and has been reviewed by the W3C Membership, who favor its widespread

Facial models allow "band-efficient" video communication

Is it possible to combine a three-dimensional wire model of a face with real pictures of the same face? And is it possible to get the computer that is forming the new image to follow the face even when the person in question makes sudden movements or partially covers her face with her hand? These are a couple of the research questions for the Image Coding Group at the Department of Electrical Engineering at Linköping University in Sweden. The aim is to find a new technology for information-efficient

"Electronic Tongue" tastes fluids.

Several years ago an “electronic nose” was developed at Linköping University in Sweden. It was based on a number of different gas sensors and programmed to differentiate between various substances in air. This nose is now being joined by a corresponding sensor for fluids, the “electronic tongue.” The principle behind the “electronic tongue” is that a number of electrodes are submerged in the fluid. When a current is turned on across the electrodes the response varies depending on the liquid’s content

Striped nanowires shrink electronics

Wires one-millionth of a millimetre wide change composition along their length.

Wires one-millionth of a millimetre wide that change chemical composition along their length, just as fruit pastilles change flavour along a packet, have been grown in the United States. These multi-flavoured nanowires can act as miniature bar-codes, diodes and light sources.

Conventional microelectronics components are etched into flat layers of semiconducting material. Charles Lieber and collea
