Breakthrough in Optical Fiber Communications

Breakthrough in Optical Fiber Communications

Researchers from the University of Southampton have revealed a breakthrough in optical fibre communications. Academics from the University’s Optoelectronics Research Centre (ORC) have collaborated with colleagues at Eblana Photonics Inc, in Ireland, to develop an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals.   The [...]

Instant-Start Computers With New Breakthrough

Instant-Start Computers With New Breakthrough

To encode data, today’s computer memory technology uses electric currents — a major limiting factor for reliability and shrinkability, and the source of significant power consumption. If data could instead be encoded without current — for example, by an electric field applied across an insulator — it would require much less energy, and make things [...]

Citizens’ Computers to Seek Ebola Cure

Citizens’ Computers to Seek Ebola Cure

Although some medical therapies show promise as treatments for Ebola, scientists are still looking urgently for a definitive cure.   For the first time, anyone with access to a computer or Android-based mobile device can help scientists perform this critical research — no financial contribution, passport or PhD necessary. In fact, volunteers can be asleep, [...]

Engineers Efficiently ‘Mix’ Light at Nanoscale

Engineers Efficiently ‘Mix’ Light at Nanoscale

The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals of computation, mixing two inputs into a single output, currently require too much space and power when done with light. [...]

Magic Tricks Created Using Artificial Intelligence for the First Time

Magic Tricks Created Using Artificial Intelligence for the First Time

Researchers working on artificial intelligence at Queen Mary University of London have taught a computer to create magic tricks.   The researchers gave a computer program the outline of how a magic jigsaw puzzle and a mind reading card trick work, as well the results of experiments into how humans understand magic tricks, and the [...]

Self-Repairing Software Tackles Malware

Self-Repairing Software Tackles Malware

University of Utah computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer again.   A3 is a software suite that works with a virtual machine — a virtual computer [...]

Virtual Reality Speeds Up Rehabilitation

Virtual Reality Speeds Up Rehabilitation

The Hong Kong Polytechnic University has successfully developed a novel training programme using haptic technology for impaired hands that cannot function normally. This programme is unique as it provides force feedback, which creates a true sense of weight to the user through the control device.   Our hands are essential to our lives; we need [...]

Harnessing Error-Prone Chips

Harnessing Error-Prone Chips

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption.   With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. [...]

New Window on the Early Universe

New Window on the Early Universe

Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy [...]

Superconducting Circuits, Simplified

Superconducting Circuits, Simplified

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today’s chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet’s most popular sites.   Superconducting chips also promise greater processing power: Superconducting circuits that use [...]
