New switchable material Two MIT researchers developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its new configuration until switched back by another voltage. The discovery could pave the way for a new kind of nonvolatile memory. The findings involve the thin-... » read more

Printing hair Using a low-cost, 3D printing technique, Carnegie Mellon University has found a way to produce hair-like strands and fibers. The printer produces plastic hair strand by strand. It takes about 20-25 minutes to generate hair on 10 square millimeters. A video can be seen here.

Quantum computing At this week’s IEEE International Electron Devices Meeting (IEDM) in Washington, D.C., chipmakers, research institutes and universities presented a plethora of papers on several subjects. A large number of papers revolve around the same theme—How to extend Moore’s Law. For this, researchers are working on a number of short- and long-term technologies to propel device... » read more

Extracting the right information in large data sets When solving complex scientific problems, researchers sometimes encounter what is called the curse of dimensionality, that is, they have so much data that they cannot efficiently analyze it. Large data sets can also be expensive and time consuming to acquire, so it is critical to gather only what is necessary. To this end, University of Il... » read more

Asteroid mining and metrology The U.S. House of Representatives has approved a new space bill. The bill, entitled H.R. 2262— U.S. Commercial Space Launch Competitiveness, includes a provision that discusses the rights for companies that mine any materials on asteroids. In simple terms, the bill recognizes the right of U.S. companies to own asteroid resources that they mine in space, accordin... » read more

Algorithmic photo captioning Researchers at Idiap, an EPFL-affiliated research institute in Martigny have developed an algorithm that can describe an image without having to pull up captions that it has already learned by using a program that makes vector representations of images and captions based on an analysis of caption syntax. Rémi Lebret, a PhD student specializing in Deep Learning ... » read more

Singing to your storage Existing research on 'racetrack memory', which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic bits of data run like racing cars around a track, has focused on using either magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency. ... » read more

Turning electric signals into light signals Transmitting large amounts of data, such as those needed to keep the internet running, requires high-performance modulators that turn electric signals into light signals, and now, researchers at ETH Zurich have developed a modulator they say is a hundred times smaller than conventional models. They reminded that in 1880, Alexander Graham Bell deve... » read more

Direct solar energy storage Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes wate... » read more

Subcutaneous medicine chip A biosensor chip developed at EPFL is capable of simultaneously monitoring the concentration of a number of molecules, such as glucose and cholesterol, and certain drugs. It’s only a centimeter long, placed under a patient’s skin, powered by a patch on the surface of the skin, and communicates with a mobile phone.
