Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1’s and 0’s were represented by bursts of light, instead of electricity. Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires.
Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles. This gives key insight to how iron oxide, one of the most abundant minerals in soil, behaves and alters the condition of soil and water around it. This also demonstrates the potential of time-resolved X-ray and optical methods to study chemical reactions at the subnanoscale in other semiconductors.
Bracelets and amulets are in the works at Dartmouth’s Institute for Security, Technology, and Society . Rather than items of mere adornment, the scientists and engineers are constructing personal mobile health (mHealth) devices—highly functional jewelry, as it were. mHealth is a rapidly growing field where technology helps you or your physician monitor your health through mobile devices.
Researchers from North Carolina State University have developed a new software tool to prevent performance disruptions in cloud computing systems by automatically identifying and responding to potential anomalies before they can develop into problems. Cloud computing enables users to create multiple “virtual machines” that operate independently, even though they are all operating on one large computing platform.
An invisible quick response (QR) code has been created by researchers in an attempt to increase security on printed documents and reduce the possibility of counterfeiting, a problem which costs governments and private industries billions of pounds each year. Publishing their research today, 12 September, in IOP Publishing's journal Nanotechnology , the researchers from the University of South Dakota and South Dakota School of Mines and Technology believe the new style of QR code could also be used to authenticate virtually any solid object.
Millions of us send billions of emails back and forth each day without much concern for their security. On the whole, security is not a primary concern for most day-to-day emails, but some emails do contain personal, proprietary and sensitive information, documents, media, photos, videos and sound files.
Probe storage devices read and write data by making nanoscale marks on a surface through physical contact. The technology may one day extend the data density limits of conventional magnetic and optical storage, but current probes have limited lifespans due to mechanical wear. A research team, led by Intel Corp.
Wattvision 2 links directly to your power meter – analog or digital – and sends your home’s energy data straight to its servers. The company’s open API allows for direct access through a smartphone app or on your laptop through the Internet. Sorted into real-time charts, the data will allow users to monitor their power usage by honing in on specific appliances to see how much energy they use.
We know Apple is vehemently against being copied, but the iPhone maker might be taking a page out of Pandora ‘s playbook. It may be, according to a report on the Wall Street Journal , creating a similar service. The WSJ article says Apple is attempting to negotiate its own licensing deals with record companies as opposed to the government-set rates paid by Pandora.
Student body ID cards with RFID-embedded chips. Image: Northside Independent School District Just as the U.S. Department of Agriculture mandates Radio Frequency Identification Device chips to monitor livestock , a Texas school district just begun implanting the devices on student identification cards to monitor pupils’ movements on campus, and to track them as they come and go from school.
element14 , the first collaborative community and electronics store for design engineers and electronics enthusiasts and a part of global electronics distributor Premier Farnell [LON:PFL], announced today that it is co-sponsoring two free 1-hour webinar s with Freescale Semiconductor entitled, “ Energy efficient designs made simple with the rich enablement of Kinetis L series microcontrollers” on Wednesday, September 12, 2012 at 12 noon CDT and on Wednesday, October 10, 2012 at 12 noon CDT.
Most startups today are building some kind of app or software—like the next big-time photo-sharing app. Double Robotics is the rare startup that's actually building a solid piece of hardware that you can actually see in action, in the real world. Right now, Double is building motorized mounts for your iPad .
Amino Communications and Celeno Communications announced that Amino’s A140/A540 set-top boxes (STBs) will now be complemented by a Wi-Fi USB solution using Celeno’s video-grade Wi-Fi technology. The Amino Wi-Fi USB dongle enables service providers to offer a video-grade Wi-Fi solution that accelerates the adoption of IP-based video services by enabling after-market IP STBs to wirelessly receive HD content.
Despite the slew of mobile payment products that have launched, we're at least another decade away from replacing wallets altogether , says Wired . Currently, mobile payment solutions only replace parts of the physical wallet. And until all stores accept smart phone payments, we won't be able to ditch the leather.
For every well-branded Retina Display or PureView camera , there are dozens of smart technologies in mobile devices that go entirely unrecognised for their impact on this world. Somewhere in the middle sits the humble accelerometer -- the tiny component that detects which way up you're holding your phone, or how you're swinging your games console controller.
