Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

For how long can the Earth support complex life before entering an irreversible zone from an environmental perspective? “Billions of years” estimates are being replaced by ‘hard thresholds’ in the ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Scientists at Yale and in Singapore have devised what may be the ultimate acid test — a comprehensive model for estimating the origins of Earth’s habitability, based in part on ocean acidity. The new ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

Scientists say Earth’s magnetic field may have funneled atmospheric particles to the moon for billions of years. Lunar soil could preserve a record of Earth’s past while providing resources for future ...

Scientists have traced the origins of complex life to the breakup of the supercontinent Nuna 1.5 billion years ago. This tectonic shift reduced volcanic carbon emissions, expanded shallow seas, and ...

Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H 2 O), nitrogen (in atmospheric N 2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...
