Electrons whizzing through a grid-like lattice don’t behave like pretty silver spheres in a pinball machine at all. They blur and bend in collective dances, following the whims of an undulating reality that is quite difficult to imagine, even less to calculate. And yet, scientists have managed to do just that, capturing the motion of …

‘Something is seriously wrong’: room temperature superconductivity study retracted

In 2020, Ranga Dias, a physicist at the University of Rochester, and his colleagues published a sensational result in Nature, featured on its cover. They claimed to have discovered a room-temperature superconductor: a material in which electric current flows frictionlessly without the need for special cooling systems. Although it was just a grain of carbon, …
