Future Computers Built from Magnetic ‘Tornadoes’

Magnetic materials form the basis of most hard disc drives as they are able to store data. A team from the University of Sheffield’s Faculty of Engineering have been investigating whether they could also be used to perform calculations, and so take on the role of a computer’s central processing unit (CPU). Lead researcher, Dr [...]

Mind-Controlled Prosthetic Arms in Daily Life

Mind-Controlled Prosthetic Arms in Daily Life

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.   In January 2013 a Swedish arm amputee was the first person in the world to receive a prosthesis with a direct [...]

New Laser Sensing Technology for Self-Driving Cars, Smartphones and 3-D Video Games

New Laser Sensing Technology for Self-Driving Cars, Smartphones and 3-D Video Games

A new twist on 3-D imaging technology could one day enable your self-driving car to spot a child in the street half a block away, let you answer your Smartphone from across the room with a wave of your hand, or play “virtual tennis” on your driveway.   The new system, developed by researchers at [...]

Magnetic Vortices for Nanoscale Antennas

Magnetic Vortices for Nanoscale Antennas

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work, published in Nature Communications, shows that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper [...]

New Record Set for Data-Transfer Speeds

New Record Set for Data-Transfer Speeds

Researchers at IBM have set a new record for data transmission over a multimode optical fiber, a type of cable that is typically used to connect nearby computers within a single building or on a campus. The achievement demonstrated that the standard, existing technology for sending data over short distances should be able to meet [...]

Device Enables Blind to ‘See’ Colors, Shapes

Device Enables Blind to ‘See’ Colors, Shapes

Using auditory or tactile stimulation, Sensory Substitution Devices (SSDs) provide representations of visual information and can help the blind “see” colors and shapes. SSDs scan images and transform the information into audio or touch signals that users are trained to understand, enabling them to recognize the image without seeing it.   Currently SSDs are not [...]

Diagnostic Imaging: New Chip Provides Better All-Round Performance

Diagnostic Imaging: New Chip Provides Better All-Round Performance

Small optical devices are important for diagnostic imaging in the body; they serve, for example, as optical probes in blood vessels or the gastrointestinal tract. For accurate diagnosis, such applications require a 360-degree view of their environment.   A microelectromechanical silicon chip developed by researchers from the A*STAR Institute of Microelectronics, Singapore, in collaboration with [...]
