Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting ...

When the magnetic field around the Earth grows stronger, oxygen levels rise. That is the surprising finding of a new study looking at more than half a billion years of planetary history.

Earth’s magnetic field seems to correlate with conditions that helped complex life to thrive — a discovery that could aid the search for life on distant exoplanets.

A weaker magnetic field could account for the higher levels of oxygen recorded in the Earth’s atmosphere and oceans around that time — and for the ensuing proliferation of macroscopic marine ...

The new findings suggest that the weakening of the magnetic field enabled this oxygen boost, which, in turn, led to a new phase of evolution. "If we're right, this is a pretty profound event in ...

A bizarre drop in the strength of the magnetic field has been found to have occurred between 591 and 565 million years ago, which coincides with a major increase in the oxygen levels in Earth's ...

The researchers believe that a weak magnetic field may have led to an increase in oxygen in the atmosphere, allowing early complex life to evolve. The intensity of Earth’s magnetic field is ...

oxygen-breathing multicellular organisms. The wave of evolution just as the magnetic field weakened is “so striking that we felt this could not just be a coincidence,” said John Tarduno ...

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that ...
