All across the world, top labs and citizen scientists alike are racing to replicate the results of a viral study that claimed to have invented a long-sought technology that could revolutionize our daily lives: a room-temperature superconductor.

Superconductors are special materials that allow electricity to pass through them with no resistance, a property that opened the door to countless technical advances from MRI machines, to particle accelerators, to electrical power grids. However, these materials typically have to be cooled to frigid temperatures or put under intense pressure to work their magic, a limitation that has constrained their practical development. For this reason, the invention of a superconductor that runs at room temperature and pressure is considered a holy grail in the physics community.
