Artist Albert Robida imagined in 1882 how air travel might look in future.
More than a century since humans learned to fly, we need to revolutionise how we stay up there.
Helium is a vital element in several industries, and a global shortage could have devastating effects.
Renewed helium exploration in Western Canada may provide new sources to address the global shortage.

Helium lifts balloons and makes our voices squeak. But its supply on Earth is finite and is critical for modern industrial processes and medical imaging in hospitals. How worried should we be?
Have telescopes, will travel: English astronomers await an 1871 eclipse in India.
The Illustrated London News, 1872
For centuries, scientists have known when and where eclipses will be visible. They pack their bags, head for the line of totality and hope for the best – which doesn't always happen.
Mine’s a Star-opramen.
It's like one great big distillery up there.

Fusion development takes time. It cannot be developed in miniature and then be simply scaled up. But we must work now, to make it possible to meet humanity's need for abundant, clean energy.
MRI scanners need liquid helium to cool their magnets.
Vast reserves of crucial helium have been found in Tanzania. Here's how the scientists did it.

A new scanning helium microscope offers the potential for capturing images with finer resolution than optical microscopes, but without damaging samples as with electron microscopes.
The gas we’ve taken for granted is in increasingly limited supply.

Helium demand is rapidly outpacing supply, cheap helium is gone forever and rationing is inevitable. More disturbingly is that a global helium supply crisis is looming this year. The fact is that the US…
Many of us love helium balloons but we need to find and conserve more for use in MRI scanners.
Helium is God’s gift to humankind. It’s particularly fantastic for science and medicine and has allowed us to make an enormous number of fundamental advances. We use it for a whole vast array of things…
