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.

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

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

The best time of day to take iron supplements depends on the person and their dosing regimen, but the experts agree that the ...

If venusian clouds contain life, it will be very different than what we know. But terrestrial analogs might still give us ...

Research examines how lectins, oxalates, and phytates in plant foods may impact nutrients and health—balancing benefits ...

The diamond anvil crushed iron and helium together under conditions mimicking those inside the Earth, to create a new compound. These compounds remained stable when pressures were reduced.

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

The exception is iron. “It’s important to leave a one- to two-hour gap between your iron supplements and your cup of coffee ...
