Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage. Their hybrid structure may be more reliable than other nanowire-based memory devices recently built and more easily integrated into commercial applications.

In the internet age, when 120,000,000 smart people on Digg can see an article about your technology, it takes some real courage to use the term "unbreakable", but the guys at NIST are doing just that.

MIT researchers were recently able to light a 60W light bulb from a power source seven feet away; there was no physical connection between the source and the appliance.

Transporting energy without any loss, travelling in magnetically levitated trains, carrying out medical imaging (MRI) with small-scale equipment: all these things could come true if we had superconducting materials that worked at room temperature. Today, researchers at CNRS have taken another step forward on the road leading to this ultimate goal. They have revealed the metallic nature of a class of so-called critical high-temperature superconducting materials. This result has been eagerly awaited for 20 years.

Researchers at the University of Illinois are developing panels of microcavity plasma lamps that may soon brighten people’s lives. The thin, lightweight panels could be used for residential and commercial lighting, and for certain types of biomedical applications.Cross-sectional diagram of a flat lamp structure based on aluminum foil encapsulated in saphire and a thin glass coating.

Albert Einstein’s theory of general relativity has fascinated physicists and generated debate about the origin of the universe and the structure of objects like black holes and complex stars called quasars. A major focus has been on confirming the existence of the gravitomagnetic field, as well as gravitational waves.

It was a grainy image of a baby—just 5 centimeters by 5 centimeters—but it turned out to be the well from which satellite imaging, CAT scans, bar codes on packaging, desktop publishing, digital photography and a host of other imaging technologies sprang.

Particles of light serving as “quantum keys”—the latest in encryption technology—have been sent over a record-setting 200-kilometer fiber-optic link by researchers from the National Institute of Standards and Technology (NIST), NTT Corp. in Japan, and Stanford University.

The experiment, using mostly standard components and transmitting at telecommunications frequencies, offers an approach for making practical inter-city terrestrial quantum communications networks as well as long-range wireless systems using communication satellites.

A University of Alberta research team has combined two fields of study in nanotechnology to create a third field that the researchers believe will lead to revolutionary advances in computer electronics, among many other areas.

Dr. Abdulhakem Elezzabi and his colleagues have applied plasmonics principles to spintronics technology and created a novel way to control the quantum state of an electron's spin.

Polymer matrix composites with carbon black can be used as filler material and can beneficially modify the electrical and mechanical properties of the used matrixes. The polymer components of these composites are traditionally made using oleo-polymers; however, an alternative is to use natural and renewable sources as soybean oil, linseed oil, sunflower oil, etc.
