Is this the superconductor of scientists’ dreams? A new claim faces scrutiny

It allegedly transmits electricity with no resistance at room temperature and moderate pressure

Researchers claim to have squeezed room temperature superconductivity out of a compound made of hydrogen, nitrogen and lutetium using diamond anvils like these.
