Just a few years ago, the average computer user’s documents, applications and even photos seemed to rattle around a 120 GB disk drive. Today’s multimedia-intensive user can exhaust that capacity in no time and engineers expect to max out conventional magnetic storage techniques by about 2010.

At that point, they’ll be looking for nanotechnology to step up.

An international team including researcher Ermanno Borra, from Université Laval’s Center for Optics, Photonics, and Laser, have found a combination of materials that allows the creation of a highly reflective liquid mirror capable of functioning even on the moon's harsh landscape.

Science fiction? Not at all.

Engineers at Purdue University are developing robots able to make "educated guesses" about what lies ahead as they traverse unfamiliar surroundings, reducing the amount of time it takes to successfully navigate those environments.

The method works by using a new software algorithm that enables a robot to create partial maps as it travels through an environment for the first time. The robot refers to this partial map to predict what lies ahead.

By precisely controlling billions of individual electrons every second, they hope to develop new computing systems and increase the security of digital communication.

Much like the conveyor belt in a production plant, NPL’s electron surf machine delivers electrons one by one in a reliable steady stream at a rate of more than a billion a second. Whilst small streams of electrons can already be produced, until now no one has found a way to deliver them in a controlled fashion at such a high rate.

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.

Researchers at NIST, in collaboration with scientists from the University of Maryland and Howard University, have developed a technique to create tiny, highly efficient light-emitting diodes (LEDs) from nanowires. As described in a recent paper,* the fabricated LEDs emit ultraviolet light—a key wavelength range required for many light-based nanotechnologies, including data storage—and the assembly technique is well-suited for scaling to commercial production.Micrograph of a complete nanowire LED with the end contact.
