Nanoelectronic circuits that operate more than 10,000 times faster than current microprocessors
Article

Circuits that can operate at frequencies up to 245 terahertz — tens of thousands times faster than today’s state-of-the-art microprocessors — have been designed and fabricated by researchers at National University of Singapore and Agency for Science, Technology and Research (A*STAR). The new circuits can potentially be used to construct ultra-fast computers or single-molecule...

Researchers Design Trees that Make it Easier to Produce Paper
Article

Researchers have genetically engineered trees that will be easier to break down to produce paper and biofuel, a breakthrough that will mean using fewer chemicals, less energy and creating fewer environmental pollutants. "One of the largest impediments for the pulp and paper industry as well as the emerging biofuel industry is a polymer found in wood known as lignin," says Shawn...

High-speed optical information processing on chips inspired by human brain
Article

In a recent publication in Nature Communications researchers from Ghent University report on a new technique for optical information processing on chips using techniques inspired by the way our brain works. Although neural networks have been used in the past to solve pattern recognition problems such as speech and image recognition, it was usually in software on a conventional computer. Ghent...

Computing with slime
Article

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors. Andrew Adamatzky (University of the West of England, Bristol, UK) and Theresa Schubert (Bauhaus-...

Ultra-Thin Light Detectors
Article

Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light detectors. Until now, it has been hard to couple light into these layered semiconductor systems. Scientists at Vienna University of Technology solved this problem. They...

Multi-party quantum communication now possible, physicists demonstrate
Article

Physicists at the Institute for Quantum Computing (IQC) at the University of Waterloo have demonstrated the distribution of three entangled photons at three different locations (Alice, Bob, and Charlie) several hundreds of meters apart for the first time, proving quantum nonlocality for more than two entangled photons. The findings of the experiment, Experimental Three-Particle Quantum...

Globr lets users chat, regardless of language
Article

The internet has connected and flattened the world in ways previously unimaginable. Coupled with ever more seamless translation tools, it provides the ability to communicate across borders and languages. Now, a new instant messaging tool is looking to make communication for speakers of different languages even easier. Globr provides its users with the ability to communicate via instant messaging...

No-refrigeration, spray vaccine could curb diseases in remote areas
Article

A new kind of single-dose vaccine that comes in a nasal spray and doesn’t require refrigeration could dramatically alter the public health landscape — get more people vaccinated around the world and address the looming threats of emerging and re-emerging diseases. Researchers presented the latest design and testing of these “nanovaccines” at the 247th National Meeting...

Solar cell material that can absorb light during the day and emit light at night
Article

In future, when your mobile or tablet runs out of battery, you could just recharge it by putting it out in the sun. Nanyang Technological University (NTU) scientists have developed a next-generation solar cell material which can also emit light, in addition to converting light to electricity. This solar cell is developed from Perovskite, a promising material that could hold the key to creating...

Panasonic Develops Power Supply Container as a Stand-alone Photovoltaic Power Package for Areas Without Electricity
Article

Panasonic Corporation today announced it has developed the "Power Supply Container", a stand-alone photovoltaic power package, for areas without electricity. The Power Supply Container contains solar modules*1 and lead-acid batteries*2, as well as the newly developed Power Supply Control Unit that acts as the energy management system. In addition, the Project to Improve Elementary...
