Revolutionizing radar: Integrated THz emitter for precise rotating target detection
You may not realize it, but the Doppler effect is everywhere in our lives, from tracking the speed of cars with radar to locating satellites in the sky. It's all about how waves change their frequency when a source (like a radar signal) and a detecto.....»»

Scientists discover new molecule that combats viral infection in bacteria
A Ph.D. researcher at the University of St Andrews studying microbes in the human gut has discovered a new molecule that acts as a "distress signal" when viruses are detected. The research is published in the journal Nature......»»
Hidden information extraction from layered structures through terahertz imaging
Noninvasive inspection of layered structures is challenging for time-resolved imaging methods, where the resolution and contrast can be compromised by prominent signal attenuation with interlayer reflections and dispersions......»»
Researchers use measurements to generate quantum entanglement and teleportation
Quantum mechanics is full of weird phenomena, but perhaps none as weird as the role measurement plays in the theory. Since a measurement tends to destroy the "quantumness" of a system, it seems to be the mysterious link between the quantum and classi.....»»
