Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

For decades, noble gases like helium have been considered chemically inert, refusing to form stable bonds under normal conditions. But new research challenges this assumption, revealing that helium ...

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell to ...

For decades, scientists have puzzled over traces of primordial helium—a rare isotope known as ³He—escaping from volcanic rocks in places like Hawaii and Iceland. Unlike the more common ⁴He, which is ...

Helium is one of our few non-renewable resources, and yet it is critical for many applications as an inert gas and as one of the coldest substances known. The unique properties of this “endangered ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

It took some detective work, but they think they know what was the cause. The MRI machine uses liquid helium to cool its powerful magnets. Turns out the helium had leaked and over 5 hours about ...

"Though we carried out the material syntheses under high temperatures, the chemical-sensing measurements were done at extremely cold, or cryogenic, temperatures. This way prevented helium from ...
