Best of Last Week – A novel phase of matter, carcinogenic meat and how the brain erases unimportant stuff

(—It was an interesting week for physics, as one team in the U.S. uncovered a novel phase of matter—it was characterized by an unusual ordering of electrons and wasn’t based on any theoretical predictions. Another team at Purdue University observed a phase transition that was thought impossible—electrons transitioning from a topologically ordered phase to one with broken symmetry under certain conditions. And in a bit of applied physics, a collaborative effort in Britain has led to the invention of a sonic tractor beam—they used it to lift and move objects. —> Read More
