In this undated photo released by the U.S. Department of Agriculture are rare-earth oxides, clockwise from top center: praseodymium, cerium, lanthanum, neodymium, samarium, and gadolinium.

Now there’s a rush in the U.S. to find key components of cellphones, televisions, weapons systems, wind turbines, MRI machine
