Nanomaterials based Biosensors chips can detect Biowarfare agents (BWAs) in real time and enhance soldiers performance

The purpose of a biosensor is the detection of biologically-relevant targets such as proteins, DNA, pathogens, cells, bacteria, pollutants, hormones and enzymes. In most cases, their presence and/or concentration in samples such as blood, urine, saliva, sweat or tears can be an early indicator of disease, so that the sensor …

US Regains TOP500 Crown with Summit Supercomputer, China gradually increasing its lead over other countries in Supercomputer race

A supercomputer is a computer with a high level of computing performance compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). There are supercomputers which can perform up to nearly a hundred quadrillions of FLOPS, …
