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 [...]

Computers: Powerful Allies in Fight Against AIDS

Computers: Powerful Allies in Fight Against AIDS

Effective treatment of HIV-virus is a race against time: Many of the drugs that have been potent killers of HIV-virus, have today lost their power, because the virus has become resistant to them. As a result science must constantly develop new drugs that can attack the virus in new ways.   Now researchers from the [...]
