System Bits: Sept. 11


Everything’s faster in Texas The Frontera supercomputing system was formally unveiled last week at the Texas Advanced Computing Center. The system was deployed in June on the University of Texas at Austin campus. It is the fifth-fastest supercomputer in the world at present and the world's fastest academic supercomputer. Dell EMC and Intel collaborated on fitting out Frontera. Work beg... » read more

The sound of typing Cybersecurity researchers at the Southern Methodist University found a way to detect what a user is typing based on sensor data collected from a nearby smartphone. The team found that acoustic signals produced by typing on a computer keyboard can successfully be picked up by a smartphone, which can then be processed to determine which keys were struck – even in noisy conf... » read more

Optical memory Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip. The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Origami battery A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions. The researchers, from Binghamton University, previously developed a paper-based origami battery. The first design, shaped like a matchbook, stacked four modules together. The ninja star version, which measures about 2.5 inches ... » read more
