New experiments suggest that molten rock deep inside Earth can absorb and store large amounts of dissolved oxygen under extreme pressure.

As magma rises toward the surface, falling pressure may release this stored oxygen into the atmosphere. The discovery could offer a new explanation for ancient changes in Earth's oxygen levels and reshape our understanding of the planet's geological history.
