Wildbear writes: Supplies of helium, a nonrenewable element, are becoming increasingly scarce. Superconducting magnets used for MRI machines and other equipment require its extremely cold temperature, which no other element can achieve. Doctors and scientists are wondering how future needs for super-cooling will be met.
"There's only a finite amount of helium in Earth's crust," [Harvard University physicist] Kim said. "Once it evaporates off, it's completely lost into outer space."
