Unlike fictional laser swords, real laser beams do not interact with each other when they cross — unless the beams meet within a suitable material allowing for nonlinear light-matter interaction.… Read More »Mixing laser- and x-ray-beams

Researchers have reported a nano-sized neuromorphic memory device that emulates neurons and synapses simultaneously in a unit cell, another step toward completing the goal of neuromorphic computing designed to rigorously… Read More »Neuromorphic memory device simulates neurons and synapses

An international research collaboration has discovered how to exploit certain defects to protect confined energy in acoustics systems. Their experimental approach provides a versatile platform to create at-will defects for… Read More »Researchers find imperfections provide protection for system symmetry

Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth’s core, where temperatures are so high that… Read More »Flow of liquid metals found to exhibit surprising turbulence
