Potential sources of helium revealed, as reserves of the precious gas dwindle
by Helen Thomson from on (#HWS7)
Helium, used in nuclear, medical and, yes, party industries, has become scarce, but new research has revealed a possible way to pinpoint fresh sources
A few years ago, we were warned that the world's helium reserves were running out. Today, researchers announced there may be several potential new sources of the precious gas hidden throughout the world.
Helium, which is used widely in nuclear, medical and party industries, has become worryingly scarce. Despite it being the second most abundant element in the universe, here on Earth it's rare - it is so light that it leaks away into space - and our major resources are running low.
