Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It
The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ...
The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its core fuses hydrogen atoms into helium, fueling the cosmic fire that ...
The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity. Over the past couple of years, solar activity—as measured by ...
Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The ...
