Early Tuesday, the world's most established exchange for bitcoin disappeared from the Internet, sending the price of the virtual currency tumbling and prompting fears that the world's biggest experiment in electronic cash could soon be strangled by fraud or regulation.
The founders of DVR pioneer TiVo are shifting their focus from broadcast TV to broadband Internet as they introduce a new device designed to make it easier for people to find and manage video. The sequel gets underway Tuesday with the release of the Qplay, a box that sorts and streams video clips compiled from all over the Internet.
Samsung is banking on you shaping up this spring. The company on Monday unveiled its new Galaxy S5 smartphone, which is set to go on sale in April, along with a pair of watches. And many of the features included on the devices focus on fitness.
Samsung's upcoming Galaxy S5 smartphone will be at least the third to have a fingerprint sensor for security but it's alone in letting you use that for general shopping, thanks to a partnership with PayPal. The sensor brings convenience for entering passcodes and could encourage more people to lock their phones. But fingerprint security isn't foolproof.
Mouser Electronics, Inc. is happy to announce their new Open Source Hardware (OSHW) technology site. This new highly interactive site contains plenty of useful information on many of the latest open source hardware boards and accessories, including BeagleBone, Arduino, Netduino, STMicroelectronics Nucleo, Texas Instruments LaunchPad, and the Intel Galileo.
Many U.S. counties have incorporated electronic voting technology. Although these updated systems have solved some usability problems, they present a new set of issues for voters unfamiliar with the technology. A study published in Human Factors examines how smartphone-based voting systems can be incorporated into the current large-scale election process.
With global greenhouse gas emissions continuing to increase proposals to limit the effects of climate change through the large-scale manipulation of the Earth system are increasingly being discussed. Researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel have now studied with computer simulations the long-term global consequences of several “climate engineering” methods.
Imagine a user who intends to send $2 to a friend through PayPal. Embedded malware in the user’s laptop, however, converts the $2 transaction into a $2,000 transfer to the account of the malware author instead. Researchers at Georgia Tech have created a prototype software, Gyrus, that takes extra steps to prevent malware from sending spam emails and instant messages, and blocking unauthorized commands such as money transfers.
Global electronic components distributor Digi-Key Corporation has added several new suppliers in response to customer demand for Internet of Things (IoT) solutions. As device connectivity becomes more prevalent, embedded and wireless suppliers offering machine-to-machine M2M solutions are choosing Digi-Key to expand their customer reach on a global scale.
Every second, your computer must process billions of computational steps to produce even the simplest outputs. Imagine if every one of those steps could be made just a tiny bit more efficient. "It would save precious nanoseconds," explained Northeastern University assistant professor of physics Swastik Kar.
Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanoparticles — which are about the same size as viruses — as well as how to prevent viral infection from occurring.
Sen. Elizabeth Warren (D-Mass.) and Rep. Katherine Clark (D-Mass.) visited MIT’s Plasma Science and Fusion Center (PSFC) yesterday for the official restart of the Alcator C-Mod tokamak. The resumption of work by nearly 100 staff, faculty, and graduate students on the project follows recent congressional budget action, which reversed an earlier proposal by the Department of Energy (DOE) to shut down the C-Mod program. The politicians w...
Producing second-generation biofuel from dead plant tissue is environmetally friendly - but it is also expensive because the process as used today needs expensive enzymes, and large companies dominate this market. Now a Danish/Iraqi collaboration presents a new technique that avoids the expensive enzymes. The production of second generation biofuels thus becomes cheaper, probably attracting many more producers and competition, and this...
A Chinese-U.S. research team is exploring the use of metamaterials -- artificial materials engineered to have exotic properties not found in nature -- to create devices that manipulate sound in versatile and unprecedented ways. In the journal Applied Physics Letters, the team reports a simple design for a device, called an acoustic field rotator, which can twist wavefronts inside it so that they appear to be propagating...
Cleaning up oil spills and metal contaminates in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally. But a group of researchers at the University of Wisconsin–Madison is examining alternative materials that can be modified to absorb oil and chemicals without absorbing water. If further developed, the technology may offer a cheaper and "greener" method to absorb oil...
