At the current rate of usage, "the world would run out in 25 years, plus or minus five years," Robert Richardson, a Cornell University physicist who won a Nobel Prize in 1996 for his work with superfluid helium, told a gathering of Nobel laureates in August.
This is troubling news for anyone who uses helium, and that's not just stores selling party balloons.
Anyone getting an MRI depends on helium, whose extremely stable, supercooling properties maintain the scanning machines' superconductive magnets. MRI machines account for more than a quarter of the helium used in the United States; it is also widely used in welding and provides the inert atmosphere necessary to manufacture optical fibers and liquid crystal display (LCD) screens.
