The hum of the Earth: Scientists record the planet’s constant low-frequency ring

Earth constantly vibrates with a low-frequency "hum," imperceptible to humans, generated primarily by ocean waves interacting ...

Missing geomagnetic reversals: Earth's past may be incomplete

Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...
