Scientists have identified a new component of the complex navigational system that allows monarch butterflies to transverse the 2,000 miles to their overwintering habitat each year. Monarchs use a ...

Monarch butterflies have a keen sense of direction, even on cloudy days. This is because they have a magnetic compass to direct their migration in addition to navigating by the position of the sun, ...

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of water are all you need to start navigating the ...

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 ...

Nocturnal insects may use both Earth's magnetic field and visual cues to guide their migratory flight behaviors, according to recent findings. The research, published in eLife, presents compelling ...
