Helium, which has many uses including the cooling medium for 
massive imaging facilities (one of my brothers is in that 
racket) is indeed more scarce since the US strategic reserve 
was abolished.

The various players and interests have not yet adjusted, 
which is an actual problem, but there's no physical shortage 
of helium so the situation will at some point resolve.
