Quantum Computing: One Step Closer with Defect-Free Logic Gate

What does hair styling have in common with quantum computing? The braiding pattern has inspired scientists as a potential new approach to quantum calculation. The idea is to rely on a network of intersecting chains, or nanowires, containing two-dimensional quasi-particles. The way these quasi-particles evolve in space time produces a braid-like pattern. These braids could […]

New UI for K-Glass 2 that Works with Eye Blinking

New UI for K-Glass 2 that Works with Eye Blinking

A newly developed user interface, the “i-Mouse,” in the K-Glass 2 tracks the user’s gaze and connects the device to the Internet through blinking eyes such as winks. This low-power interface provides smart glasses with an excellent user experience, with a long-lasting battery and augmented reality. Smart glasses are wearable computers that will likely lead […]

Mobile Quarantine Station for Malicious Android Apps

Mobile Quarantine Station for Malicious Android Apps

The attacks were perfidious: In February this year, the Czech IT security company Avast declared that it had identified several malicious game apps for mobile phones in the Google Play Store – ones that would only become criminally active on the device after several weeks. Then the affected smartphones or tablet computers would suddenly take […]

Nano Piano’s Lullaby Could Mean Storage Breakthrough

Nano Piano’s Lullaby Could Mean Storage Breakthrough

Researchers from the University of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.   “The chip’s dimensions are roughly equivalent to the thickness of human hair,” explained Kimani Toussaint, an associate professor of mechanical […]

Computer Scientists Simplify Parallel Programming

Computer Scientists Simplify Parallel Programming

Modern software takes computational speed for granted. But modern microprocessors can only speed up by increasing the number of cores. To take full advantage of multiple cores, software developers have to arrange their code in such a way that it is executable in parallel – an error-prone and expensive task. Computer scientists from Saarland University […]

Guarantees for Online Anonymity?

Guarantees for Online Anonymity?

Anonymity on the Internet is possible only up to a certain degree. Therefore, it is possible that others may see who is visiting an online advice site on sexual abuse, or who frequently looks up information about a certain disease, for example. Seeing that this kind of private information can be linked to their identity, […]

Detecting Deception Online is Not So Easy

Detecting Deception Online is Not So Easy

The sheer number of phishing scams that bombard our inboxes is an indication of the success scammers have in deceiving people through electronic communication. It is such a prevalent problem that some businesses are now taking action to defend against the scams by sending out fake phishing emails to educate employees who respond. Joey George, […]

Data Driven Discoveries: Imagine Smart Cities with Thousands of Strategically Placed Sensors

Data Driven Discoveries: Imagine Smart Cities with Thousands of Strategically Placed Sensors

As urban populations increase, so too does the complexity involved in maintaining basic services like clean water and emergency services. But one of the biggest barriers to making cities “smarter” — for example, comprehensively monitoring sources of waterway pollutants in real time — is quick and easy access to data.   Future scenarios like these […]

Energy-Generating Cloth Could Replace Batteries in Wearable Devices

Energy-Generating Cloth Could Replace Batteries in Wearable Devices

From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets’ versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome. In the journal ACS Nano, scientists report the first durable, flexible cloth that harnesses human motion to generate energy. […]
