The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading ...
A ship’s steel hull becomes part of Earth’s magnetic field, which can quietly skew a magnetic compass in different directions as the vessel turns and heels. This explains how binnacle correctors work, ...
The movement of the magnetic North Pole is the result of the Earth having an active core. The inner core, starting about ...
Measurements by the SWAN instrument onboard SOHO, have shown that the heliosphere, the solar wind filled volume which prevents the solar system from getting embedded in the local (ambient) ...
Many birds of the northern hemisphere shift their migratory course to more southerly directions when moving from northern to southern latitudes. Birds from Central Europe, for example, change their ...
The magnetic compass that birds use for orientation is affected by polarized light. That is the finding of researchers in Sweden, who studied zebra finches navigating a simple maze and found that the ...
Here's how to make a magnetic compass that points north using the amazing invisible force of magnetism. And there are only a few things that we need:A long large needle, a piece of cork carefully ...
The monarch butterfly uses a magnetic compass to guide its extraordinary migration thousands of km across North America, scientists say. Monarchs are known to possess a Sun compass but even on cloudy ...
