There will soon be about 1,100 fewer places to buy batteries. RadioShack said Tuesday that it plans to close up to 1,100 stores, or about a fifth of its U.S. locations. The news came as the retailer reported a wider quarterly loss after a disappointing holiday season. Its stock tumbled 16 percent in afternoon trading. CEO Joseph Magnacca said the closings would leave the company with more than 4,000 U.S. stores. That's still far more than Best Buy, which has roughly 1,400 U.S. locations, and makes RadioShack stores nearly as common as Wal-Mart. RadioShack didn't immediately identify which stores will...

Struggling retailer RadioShack Corp reported a wider quarterly loss on Tuesday and said it will close up to 1,100 U.S. stores after a huge drop in sales over the holidays, sending the stock down more than 15 percent. Sales at the Fort Worth, Texas-based chain have been in free fall amid executive departures, tough competition and an image problem. Despite its ubiquitous presence in the United States, analysts say it has not done enough to transform itself into a destination for mobile phone shoppers or become hip enough to woo younger shoppers. Its net loss widened to $191.4 million, or...

(Reuters) - Retailer RadioShack Corp reported a wider quarterly loss on Tuesday and said it will close up to 1,100 U.S. stores after a huge drop in sales over the holidays, sending its stock down nearly 24 percent. The planned closures would leave the Fort Worth, Texas-based chain with over 4,000 stores, including over 900 dealer franchise locations, its chief executive officer said. Sales totaled $935.4 million in the quarter covering the all-important holiday season, down 20.1 percent from $1.17 billion in the year-ago period. Analysts, on average, looked for sales of $1.12 billion, according to Thomson Reuters I/B/E/S. Sales...

Nanoparticle inks can turn your existing 2D printer into a circuit board production line – and the possibilities for 3D printers are mind-boggling. Printing foldable mobile phones on a sheet of paper from a normal 2D printer is just a decade away, according to Jürgen Steimle, head of the Embodied Interaction Group at the Max Planck Institute for Informatics in Saarbrücken, Germany. Steimle and his colleagues took a step towards this in 2013, when they used a standard printer loaded with nanoparticle ink to print a paper circuit that works even after the sheet is torn. In the past couple...

If it seems like it was exactly a year ago that turmoiling retailer Radioshack shut down 500 stores due to lack of consumer interest in its wares (and or consumer disposable cash), it is because it was. So how does Radioshack demonstrate its morbid sense of humor on the one year anniversary of said announcement? Well, by closing another 500, or about 12% of the retailer's total 4500 outlets currently in existence. The WSJ reports that the company which once was the butt of all LBO-rumor jokes (and still is, only this time in the context of an M&A-rumor...

That? Oh, that’s just a mosquito, now tell me more about your top secret project. Do you ever feel frustrated that you can’t keep tabs on your significant other at all times? Nervous that everyone is hanging out without you? Curious about what the heck your neighbors are doing over there? Thankfully, there’s a Pocket Drone currently being funded on Kickstarter that will solve these problems and more. It only takes 20 seconds to unpack and launch. Then, you can load it up with any video camera you own, as long as the payload is less than half a pound....

These days, we read about the latest reports from Edward Snowden but they’re old hat now. We all know the American government is spying on everyone. But as more leaks come out, it’s increasingly evident that the NSA’s nefarious behavior will leave a deep scar on Silicon Valley. Snowden whistleblowing and escaping from the NSA could be one of the most important boons for Asian tech companies and startups in the next decade. If, as Spiegel recently reported, the NSA has a backdoor into major US companies like Dell, Cisco, IBM, Western Digital, Seagate, and more, then Silicon Valley is...

Imagine a world where a handheld gadget scans your body and diagnoses illnesses in seconds - reducing hospital visits and potentially saving your life. It may sound like the work of science fiction but engineers in California have taken their lead from the Star Trek franchise and developed a real-life version of the show’s medical tricorder. The Scanadu Scout can read a person’s temperature, heart rate, blood oxygen levels, and more, simply being held against their forehead. It was developed by Scanadu’s CEO Walter De Brouwer, 56, at Nasa’s Ames Research Centre in California. A prototype of the Scout was...

Over the last few years, we’ve seen the price of 3D printers drop dramatically as key patents expire or the cost of components decrease. They still cost quite a bit of money, however, as much of the manufacturing and labor takes place in the U.S. Now Asian rivals, complete with cheaper labor costs, are trying to muscle their way into the market. New Kinpo Group, an electronics manufacturer out of Taiwan, has announced its first 3D printer – the da Vinci. It’s very similar to the Makerbot Replicator 2 and even has a similar build volume of 20x20x20 cm. Here...

A team of researchers from the National University of Singapore (NUS), led by Professor Loh Kian Ping, who heads the Department of Chemistry at the NUS Faculty of Science, has successfully developed an innovative one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates, opening up opportunities for graphene to be used in high-value applications that are currently not technologically feasible. This breakthrough, inspired by how beetles and tree frogs keep their feet attached to submerged leaves, is the first published technique that accomplishes both the growth and transfer steps of graphene on a silicon wafer....

High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors – and superconductivity itself – can all be traced to a single starting point, and they explain why there are so many variations. This theory might be a step toward new, higher-temperature superconductors that would revolutionize electrical engineering with more efficient motors and generators and lossless power transmission. -snip- Most subatomic particles have a tiny magnetic field – a property physicists call "spin" – and electrical resistance...

My wife and I were in a restaurant having lunch the other day with one of our sons, and couldn’t help but notice a nearby family: a mom, dad, two boys, and a daughter. The daughter was middle school age, and clearly in contemporary middle school mode: ear buds securely in place, staring off into space. Every aspect of her demeanor made it clear: I don’t want to be here, and I don’t want to be with my family. So I am going to stay in my world of music and media. By plugging in, I’m tuning out. And her...

Depressing news for those of us who appreciate great prices on computer gear and component parts. The Geeks website now displays a simple page explaining that all ordering has now ceased. Competition appears to be the overriding reason, and a general unwillingness to have been forced to this point is quite apparent. I, for one, will miss all the great deals they offer, and have offered for many years.

Online advertising giant Google's new wearable accessories are merely a stepping stone to its ultimate ambition - a microchip which can be embedded in users' brains. The company, which uses its search, email and other services to funnel personalised advertising to users, is currently trialling prototypes of its Glass device, which is worn like a pair of glasses. But Google is staking its future on a new service which will use the information it holds on registered users to automatically predict their search needs and present them with the data they want. The ultimate ambition is to literally get inside...

Samsung Electronics Co lost $12 billion in market value on Friday, hit by brokerage downgrades that have underscored concerns about slowing sales of its flagship Galaxy S4 smartphone. The shares fell 6.2%, the most in more than nine months in Seoul after analysts at JPMorgan Chase & Co. cut profit estimates. Orders for the S4 smartphone, which went on sale last month, are slowing on weak demand in Europe that may impact profit margins, analysts led by JJ Park said in a report dated yesterday, citing supply chain checks. JPMorgan cut its share- price estimate for Samsung by 9.5% to...

ORLANDO—Is it time for humans to get their own black box? That’s the provocative question behind an ambitious project by four undergraduate engineering students from the University of Massachusetts at Amherst, presented at this weekend's Cornell Cup in Orlando, Fla. Over the course of a school year, the Amherst team built a prototype “black box for humans” that you could carry around wherever you went, and could be activated to record audio of your surroundings in case you ran into trouble. That audio recording—heavily encrypted, completely tamper-proof and admissible as evidence in a U.S. courtroom, per the Amherst team—would hypothetically...

The same material that formed the first primitive transistors more than 60 years ago can be modified in a new way to advance future electronics, according to a new study. Chemists at The Ohio State University have developed the technology for making a one-atom-thick sheet of germanium, and found that it conducts electrons more than ten times faster than silicon and five times faster than conventional germanium. The material's structure is closely related to that of graphene—a much-touted two-dimensional material comprised of single layers of carbon atoms. As such, graphene shows unique properties compared to its more common multilayered counterpart,...

© Science Photo LibraryRecycling old magnets, so that rare-earth metals can be re-used, could help to solve an urgent raw material supply problem in the electronics industry. Researchers from the University of Leuven, Belgium, have used ionic liquids to separate neodymium and samarium from transition metals like iron, manganese and cobalt – all elements that are used in the construction of permanent rare-earth magnets, which are found in electronic devices ranging from hard drives to air conditioners and wind turbines.‘The process involves the liquid-liquid extraction of rare-earth metals from the other elements present in neodymium-iron-boron and samarium-cobalt magnets,’ explains Koen...

FULL TITLE: Solving nearly century-old problem: Using graphene, professor finds out what causes low-frequency electronic 1/f noise =========================================================== A University of California, Riverside Bourns College of Engineering professor and a team of researchers published a paper today that show how they solved an almost century-old problem that could further help downscale the size of electronic devices. The work, led by Alexander A. Balandin, a professor of electrical engineering at UC Riverside, focused on the low-frequency electronic 1/f noise, also known as pink noise and flicker noise. It is a signal or process with a power spectral density inversely proportional to...
