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 ...

How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

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 ...

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 ...

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard numbers.

For three years, the experiment wouldn’t work, and Henrik Mouritsen couldn’t figure out why. He had captured European robins and placed them in funnel-shaped cage in a windowless room. The funnel was ...
