Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

NASA scientists revealed the mechanism 540 million years old, associated with a shift in the Earth's magnetic field, which ...

Nature; Source: “Strong Link between Earth’s Oxygen Level and Geomagnetic Dipole Revealed since the Last 540 Million Years,” by Weija Kuang et al., in Science Advances, Vol. 11, No. 24; June ...

The strength of Earth’s magnetic field seems to rise and fall hand-in-hand with the abundance of oxygen in its atmosphere, a study of geological records spanning the last half billion years has ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

A diagram shows the mechanisms feeding Earth's two LLVPs. Panton et al. / Scientific Reports The difference in the two LLVPs could have significant ramifications, the researchers noted.

Loggerhead turtles use geomagnetic field to navigate large distances Premium Updated - February 16, 2025 04:39 pm IST The Hindu Bureau ...

Birds, fish, sea turtles, and various other animals have been reported to sense the geomagnetic field and to use it for orientation, navigation, and homing. In recent years, exciting progress has been ...

Nevertheless, researchers think it’s likely that birds not only use the Earth’s magnetic field to navigate – they also literally see the field in some way.

To identify which mechanism desert ants use, scientists from the University of Oldenburg conducted behavioral experiments. They hypothesized that animals using a particle-based system would respond to ...

Pigeons, bats and sea turtles, for example, appear to sense the geomagnetic field via magnetic particles. Behavioural experiments can distinguish between different mechanisms of magnetoreception ...
