A new worry: No helium.

The world is running out of helium, and there's no alternative.

Quote:

A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs. Strange as it sounds, the lighter-than-air element that gives balloons their buoyancy also powers the vital medical diagnostic machines. An MRI can’t function without some 2,000 liters of ultra-cold liquid helium keeping its magnets cool enough to work. But helium — a nonrenewable element found deep within the Earth’s crust — is running low, leaving hospitals wondering how to plan for a future with a much scarcer supply.
