The gas is pumped around important documents such as a map of the world dating back to 1507 in the Library of Congress, and a copy of the Magna Carta held by the U. For many years, the noble gas xenon has been researched as a treatment for brain injuries.Xenon, however, is expensive, leading researchers to turn to its noble gas cousin, argon, as a potential alternative.She has ducked under a glacier in Switzerland and poked hot lava with a stick in Hawaii.

In one, Nowrangi said, the brain as a whole seemed protected by argon, but damage to one area was actually increased with the gas treatment.

This could be because the argon didn't penetrate to that region, or because different brain regions have different cell types and cell densities.

Argon is also a good insulator, so it's often pumped into deep-sea diving dry suits to keep the diver warm.

Another use for argon is in historical preservation. Unlike reactive oxygen, the argon doesn't degrade the paper or ink on delicate documents.

The two shared the Nobel Prize in Chemistry in 1904 for the discovery.
