Scientists and engineers from an international collaboration have, for the first time, generated and manipulated single particles of light (photons) on a silicon chip. This accomplishment, which required shrinking down key components and integrating them onto a silicon microchip, is a major step forward in the race to build a quantum computer.
Google is selling Motorola's smartphone business to Lenovo for $2.9 billion, a price that makes Google's biggest acquisition look like its most expensive mistake. The deal announced Wednesday will rid Google Inc. of a financial headache that has plagued the Internet company since buying Motorola Mobility for $12.4 billion in 2012.
Scientists in Germany, inspired by the odor-processing nervous system of insects, have recently refined a new technology that is based on parallel data processing. Called neuromorphic computing, their system is composed of silicon neurons linked together in a similar fashion to the nerve cells in our brains. If the assembly is fed with data, all silicon neurons work in parallel to solve the problem.
Univ. of Houston researchers have developed a new stretchable and transparent electrical conductor, bringing the potential for a fully foldable cell phone or a flat-screen television that can be folded and carried under your arm closer to reality. The researchers report that their gold nanomesh electrodes, produced by the novel grain boundary lithography, increase resistance only slightly, even at a strain of 160%.
Google is adding prescription frames and new styles of detachable sunglasses to its computerized, Internet-connected goggles known as Glass. The move comes as Google Inc. prepares to make Glass available to the general population later this year. Glass hasn't actually had glasses in its frame until now.
Researchers in California have made progress in a project to develop fast-blinking light-emitting diode systems for underwater optical communications. They have shown that an artificial metamaterial can improve the “blink speed” of a fluorescent light-emitting dye molecule 76 times faster than normal while increasing brightness 80-fold.
A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100% accuracy over a much wider range than current systems. The system, invented in the U.K., improves the performance of passive, battery-less RFID tag detection through the use of a new antenna setup.
Transparent displays have a variety of potential applications. A number of technologies have been developed for such displays, but all have limitations. Now, researchers have come up with a new approach that can have significant advantages over existing systems, at least for certain kinds of applications: a wide viewing angle, simplicity of manufacture and potentially low cost and scalability.
Falls are a major problem for the elderly. Each year, one-third of adults over age 65 experience a fall, and one-third of those falls impact health and autonomy. The Swiss spin-off Gait Up just put an extremely thin motion sensor on the market which can detect the risk of a fall in an older person and is equally useful for sports and physical therapy.
North Carolina State Univ. researchers have used silver nanowires to develop wearable, multi-functional sensors that could be used in biomedical, military or athletic applications, including new prosthetics, robotic systems and flexible touch panels. The sensors can measure strain, pressure, human touch and bioelectronic signals such as electrocardiograms.
Police officers assigned to patrol downtown Los Angeles began wearing on-body cameras on Wednesday as the city evaluates different models to include in its policing. Police Commission President Steve Soboroff said 30 officers have volunteered for 90-day trials of devices provided by Ariz.-based Taser International Inc. and Coban Technologies Inc. of Houston.
When our Internet-connected gadgets and home appliances all learn to talk to each other, Google wants to be at the center of the conversation. This imagined future is still a few years away, but the search giant is already preparing with its $3.2 billion acquisition of high-tech thermostat and smoke-detector maker Nest Labs.
Researchers in Texas have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging. A single grain of rice could hold about 10 of these tiny windmills, and hundreds of them could be embedded in a sleeve for a cell phone.
For years engineers the world over have been trying to use inexpensive, carbon-rich molecules and plastics to create organic semiconductors. Two university research teams have worked together to produce the world’s fastest thin-film organic transistors, proving that this experimental technology has the potential to achieve the performance needed for high-resolution television screens and similar electronic devices.
Gadget lovers are slipping on fitness bands that track movement and buckling on smartwatches that let them check phone messages. Some brave souls are even donning Google's geeky-looking Glass eyewear. For the technology industry, this is exciting time, but also a risky one. No one really knows whether the average consumer can be enticed to make gadgets part of their everyday attire.
Researchers in Switzerland are developing electronic components that are thinner and more flexible than before. They can even be wrapped around a single hair without damaging the electronics. This opens up new possibilities for ultra-thin, transparent sensors that are literally easy on the eye.
Scientists are reporting the development of a novel metal ink made of small sheets of copper that can be used to write a functioning, flexible electric circuit on regular printer paper. Their report on the conductive ink, which could pave the way for a wide range of new bendable gadgets, such as electronic books that look and feel more like traditional paperbacks, appears in ACS Applied Materials & Interfaces.
Intel Corp., the world's largest maker of computer processors, says its processors are now free of minerals from mines held by armed groups in the Democratic Republic of the Congo. It's the first major U.S. technology company to make such a claim about its products.
A 310-foot "crop circle" in a California barley field that mystified locals this week was explained Sunday: it was a publicity stunt by Nvidia Corp., a maker of chips for PCs and smartphones. The company has announced the Tegra K1, a new chip for tablets and smartphones that contains 192 computing "cores," or mini-computers, for graphics applications.
A fundamental concept in graph theory is connectivity, which describes how many lines or nodes would have to be removed from a given graph to disconnect it. Progress has been made in “edge connectivity”, or the connections between nodes or vertices. But “vertex connectivity”, which looks at the nodes themselves, is less understood. It has been reexamined recently and the findings could help coax as much bandwidth as possible from networks.
Last year, Samsung and rival LG Electronics, the world's top two TV makers, touted organic light-emitting diodes (OLEDs) as the future of TV. OLED screens are ultrathin and can display images with enhanced clarity and deeper color saturation. Now, Samsung has launched a giant 110-in television that reflects global TV makers' move toward ultra HD TVs, as manufacturing bigger TVs using OLED proves too costly.
Recently, a study team from the First Affiliated Hospital, Sun Yat-sen Univ. in China has verified that virtual reality training using the Kinect system from the Xbox 360 could promote the recovery of upper limb motor function in subacute stroke patients, and brain reorganization by Kinect-based virtual reality training may be linked to the contralateral sensorimotor cortex.
The Advanced Institute for Computational Science at RIKEN has been selected by the Japanese government to develop a new exascale supercomputer. The new supercomputer, which is scheduled to begin working in 2020, will compute on the "exaflop" scale and will be about 100 times faster than the K computer which was the world’s fastest in 2011.
Solar Impulse pilot Bertrand Piccard put his mental and physiological limits to the test during a 72-hour simulated flight across the Atlantic Ocean which ended Friday.
