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.

Fight counterfeiting with fingerprint chips Given that no two human fingerprints are exactly alike, an MIT spinout uses random variations in silicon chips as authentication identifiers for consumer products. Silicon chips are similar as manufacturing processes cause microscopic variations in chips that are unpredictable, permanent, and effectively impossible to clone. MIT spinout Verayo ... » read more

Surviving entanglement breakdown Researchers at MIT have discovered that preserving the fragile quantum property known as entanglement isn’t necessary to reap benefits. By way of background, the MIT team reminded that the promise of quantum information processing, i.e., solving problems that classical computers can’t, as well as perfectly secure communication depends on a phenomenon cal... » read more

Crafting ultrathin color coatings Harvard University researchers have developed a technique that coats a metallic object with an extremely thin layer of semiconductor, just a few nanometers thick. And while the semiconductor is a steely gray color, the object ends up shining in vibrant hues because the coating exploits interference effects in the thin films. Carefully tuned in the laboratory, ... » read more

A lighter, cheaper radio wave device Researchers at The University of Texas at Austin reported that they have achieved a milestone in modern wireless and cellular telecommunications through the creation of a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices. The researchers said the circulator has the potential to double the ... » read more

Harvesting power from air A centuries-old clock built for a king is the inspiration for a group of University of Washington computer scientists and electrical engineers who hope to harvest power from the air. The clock, powered by changes in temperature and atmospheric pressure, was invented in the early 17th century by a Dutch builder. Three centuries later, Swiss engineer Jean Leon Reutter b... » read more
