Superconductors are materials that can conduct electricity with zero resistance when cooled to a certain temperature, called the critical temperature. They have applications in many fields, including ...

Ranga Dias claimed to have discovered the first room-temperature superconductors, but the work was later retracted. An investigation by Nature’s news team reveals new details about what happened — and ...

Superconductivity is a fascinating phenomenon in which certain materials exhibit zero electrical resistance and expel magnetic fields below a characteristic temperature, known as the critical ...
