Inside a drop of paint, light is scattered so often that it seems impossible to demonstrate quantum effects. But despite the thousands of possible paths the light can take, like a drunk person inside a labyrinth, researchers now show that there are just two exits.
Scientists have demonstrated how a detailed picture of the electronic states can be ascertained by systematically comparing all of the interactive electronic processes in a simple system of aqueous iron(II).
Researchers have uncovered key features of the dynamics of a form of jerky motion responsible for phenomena as diverse as squeaks and squeals in door hinges and automotive brakes, joint wear in the human body and the sudden shifting of tectonic plates leading to earthquakes.
One of the obstacles to nanomedicine is that researchers have a hard time seeing where nanoparticles go once they're inside various parts of the body. But now one team has developed a way to help overcome this problem - by making tissues and organs clearer in the lab.
Scientists have devised a way to build a quantum metamaterial using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.
To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but in a new study researchers describe a 'nanoblade' that can slice through a cell's membrane to insert mitochondria.
