New Filter Could Advance Terahertz Data Transmission

New Filter Could Advance Terahertz Data Transmission

University of Utah engineers have discovered a new approach for designing filters capable of separating different frequencies in the terahertz spectrum, the next generation of communications bandwidth that could allow cellphone users and Internet surfers to download data a thousand times faster than today. Once the filter is designed, it can be fabricated using an [...]

Fever Alarm Armband: A Wearable, Printable, Temperature Sensor

Fever Alarm Armband: A Wearable, Printable, Temperature Sensor

University of Tokyo researchers have developed a “fever alarm armband,” a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. This armband will be presented at the 2015 IEEE International Solid State Circuits Conference, San Francisco, on 22-26 February, 2015. The flexible organic components developed for this device are well-suited [...]

New Approach to Distributing Computations Could Make Multicore Chips Much Faster

New Approach to Distributing Computations Could Make Multicore Chips Much Faster

Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel.   But the ways in which a chip carves up computations can make a big difference to performance. In a 2013 paper, Daniel Sanchez, the TIBCO Founders [...]

New Algorithms Locate Where a Video Was Filmed From Its Images and Sounds

New Algorithms Locate Where a Video Was Filmed From Its Images and Sounds

Researchers from the Ramón Llull University (Spain) have created a system capable of geolocating videos by comparing their audiovisual content with a worldwide multimedia database. In the future this could help to find people who have gone missing after posting images on social networks, or even to recognise locations of terrorist executions. Many of the [...]

Analogue Quantum Computers: Still Wishful Thinking?

Many challenges lie ahead before quantum annealing, the analogue version of quantum computation, contributes to solve combinatorial optimization problems Traditional computational tools are simply not powerful enough to solve some complex optimization problems, like, for example, protein folding. Quantum annealing, a potentially successful implementation of analogue quantum computing, would bring about an ultra-performant computational method. [...]

Security Gaps Found in 39,890 Online Databases Containing Customer Data

Security Gaps Found in 39,890 Online Databases Containing Customer Data

Anyone could call up or modify several million pieces of customer data online including names, addresses and e-mails. According to the Center for IT-Security, Privacy and Accountability (CISPA) in Saarbrücken, Germany, three of its students were able to show this for 40,000 online databases in both Germany and France. The cause is a misconfigured open [...]
