Impact Amplification Researchers have considered several possibilities. External sources, such as the early solar wind or Earth’s magnetic field, were too weak or faded too early.

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

He also exposed the sharks to a magnetic field mimicking a place the exact same distance to the north. When he did that, though, the sharks didn’t seem to have a clue where they were and didn ...

Physicist Suchitra Sebastian may have discovered a new state of matter. But the hardest part was convincing the doubters.

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Earth’s Magnetic Field Might Weirdly Be Controlling the Air We Breathe, Scientists Say Magnetism and oxygen may intrinsically influence each other, but experts aren’t sure why.

Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden link between the two that’s stronger than we originally imagined.

A joint venture between NASA Goddard Space Flight Center and the University of Leeds discovered that the Earth's magnetic field strength and atmospheric oxygen levels over the past 540 million ...

What Will Happen When the Earth’s Magnetic Field Begins to Reverse? On the University of Maryland campus, a giant whirligig tries to predict the planet’s next big flip Haley Edwards May 2014 ...

The strength of Earth's magnetic field has correlated with fluctuations in atmospheric oxygen for hundreds of millions of years, according to a newly released analysis by NASA scientists ...
