Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...
Imagine you are a young Bar-tailed Godwit, a large, leggy shorebird with a long, probing bill hatched on the tundra of Alaska. As the days become shorter and the icy winter looms, you feel the urge to ...
Migratory bats use a magnetic sense to navigate long distances, calibrating their internal compass based on the position of the setting sun each evening. Many animals may use Earth’s magnetic field ...
Scientists have known for decades that many animals use the Earth's magnetic field for navigation. It's less clear how they do it. A new study suggests earthworms may be a good way to figure it ...
As alarm grows over the increasing failure of GPS systems worldwide—particularly in aviation—scientists are exploring ...
For just over two years, a scalar magnetometer developed by Graz University of Technology (TU Graz) and the Space Research Institute (IWF) of the Austrian Academy of Sciences has been on its way to ...
New satellite data show Earth’s magnetic field changing fast, with a growing weak spot over the South Atlantic.
