Use IoT Security Concerns To Your Benefit
By Ann Mutschler - 05 Feb, 2015 - Comments: 0

Did you know data scientists can now link Instagram posts and other meta-data to credit card purchases? Indeed, MIT researchers said recently that just four fairly vague pieces of information — the dates and locations of four purchases — are enough to identify 90 percent of the people in a data set recording three months of credit-card transactions by 1.1 million users. They stresse... » read more

A viable silicon substitute A new study by UC Berkeley, the University of Pennsylvania and the University of Illinois at Urbana-Champaign (UIUC) moves graphene a step closer to knocking silicon off as the dominant workhorse of the electronics industry. They reminded that while silicon is ubiquitous in semiconductors and integrated circuits, researchers have been eyeing graphene, a one-atom... » read more

Optimizing algorithms Optimization algorithms try to find the minimum values of mathematical functions, and are everywhere in engineering for such things as evaluating design tradeoffs, assessing control systems, finding patterns in data, among other things. A way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexit... » read more

Nanodiamonds are quantum’s best friend Purdue University researchers have demonstrated a new way to enhance the emission of single photons by using "hyperbolic metamaterials," in a step they say could be used in developing quantum computers and communications technologies. Optical metamaterials harness clouds of electrons called surface plasmons to manipulate and control light. The team p... » read more

Quantum computational circuits MIT researchers have built an array of light detectors sensitive enough to register the arrival of photons and mounted them on a silicon optical chip, which could be critical components of quantum computing devices. They pointed out that single-photon detectors are notoriously temperamental. For example, of 100 deposited on a chip using standard manufacturing ... » read more

A Robot In Every Home
By Ernest Worthman - 08 Jan, 2015 - Comments: 0

Bill Gates, in a 2006 Scientific American article, described his vision of the future as, "A robot in every home." It's difficult to project that far ahead with technology, though. Since then, wireless has come a long way. So have microelectronics—nearly 24 orders of magnitude if you use Moore's Law. So the robot conceived in 2006 is now more like a gaggle of Internet dust particles that r... » read more

Mini particle accelerator Researchers at MIT who succeeded last year in creating a material that could trap light and stop it in its tracks have now developed a more fundamental understanding of the process. The new work — which they said could help explain some basic physical mechanisms — shows that this behavior is connected to a wide range of other seemingly unrelated phenomena. Ligh... » read more

Measuring electrons in silicon In what is believed to be a first, a team of physicists and chemists based at UC Berkeley, Ludwig-Maximilians Universität in Munich, Germany, the University of Tsukuba, Japan, and the Molecular Foundry at the Department of Energy’s Lawrence Berkeley National Laboratory has captured images of electrons breaking free of their atomic shells using attosecond pulse... » read more

Path to quantum transistors An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics, according to University of Michigan physicists. The researchers have been able to confirm that several properties of the compound samarium hexaboride that raise hopes for... » read more

Energy Harvesting Makes Progress
By Ed Sperling - 04 Dec, 2014 - Comments: 0

The dream of a self-powered device has been around for a long time—thousands of years, in fact. The first windmills and waterwheels date back to ancient Greece and the beginning of recorded history. Self-winding timepieces date back to the late 1700s. The Foucault pendulum has been in motion in Paris, minus some brief hiatuses, since 1851. And it's been 144 years since two French physicists d... » read more
