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...

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...

MILFORD — The Pennsylvania Department of Environmental Protection (DEP) is reminding consumers and businesses that they are no longer be able to throw away their electronic devices with their trash. Passed in 2010, the Pennsylvania Covered Device Recycling Act requires that consumers and businesses not dispose of covered devices, such as computers, laptops, computer monitors, televisions and tablets with their trash. This means that trash haulers will no longer take covered devices unless the municipality has a curbside electronics collection program that ultimately sends the devices to an electronics recycler. The law took effect Jan. 24. “This law is an...

Just when you thought CES couldn’t get any randomer than Qualcomm’s “Generation Mobile” atrocity, guess who showed up? Bill Clinton, who stopped by to speak in the middle of Samsung president Stephen Woo’s presentation. Not only that, but according to CNET’s liveblog, in the midst of his remarks he digressed and started talking about gun control. The man used to be the leader of the free world; you really thought he’d get on stage at a trade show and stick to the subject? Child, please. Mr. Clinton’s appearance seemed a little random, but his philanthropic work involves attempts to close...

A dash of algebra on wireless networks promises to boost bandwidth tenfold, without new infrastructure. Academic researchers have improved wireless bandwidth by an order of magnitude—not by adding base stations, tapping more spectrum, or cranking up transmitter wattage, but by using algebra to banish the network-clogging task of resending dropped packets. By providing new ways for mobile devices to solve for missing data, the technology not only eliminates this wasteful process but also can seamlessly weave data streams from Wi-Fi and LTE—a leap forward from other approaches that toggle back and forth. "Any IP network will benefit from this technology,"...

Dissolvable electronic materials could be used in medical implants and environmentally friendly gadgets. A team of researchers has designed flexible electronic components that can dissolve inside the body, and in water. The components could be used to make smart devices that disintegrate once they are no longer useful, helping to alleviate electronic waste and enabling the development of medical implants that don’t need to be surgically removed. So far, the team has designed an imaging system that monitors tissue from within a mouse, a thermal patch that prevents infection after a surgical site is closed up, solar cells and strain...
