Best of Last Week – New definition of time crystals, new images of Pluto and the mechanism that causes neuropathic pain

(—It was an interesting week for physics as a team of researchers with the University of California and the University of Tokyo proposed a new definition of time crystals—then proved such things don’t exist—theory had suggested a system that could move despite not having enough energy to do so. Also, a team at Ecole Normale Supérieure in France demonstrated a way to control the quantum properties of light by using microwave photons to probe a superconducting circuit. And researchers working for the Department of Energy used neutrons to find the “missing” magnetism of plutonium—confirming a long held theory. —> Read More
