Confocal microscopy image of a cell from the nasal passage of a trout. The outline of the cell is indicated by a dotted line, the blue area is the nucleus, and the white substance highlighted in the ...

Salmon, turtles and many birds migrate up to thousands of miles at a time, presumably by sensing the Earth's magnetic field. Now, scientists have identified cells in the nose of trout that respond to ...

A migrating robin can keep a straight course even when it flies through a cloudy night sky, devoid of obvious landmarks. That’s because it can sense the Earth’s magnetic field. Something in its body ...

Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified ...

We learn that there are five senses (sight, hearing, touch, smell and taste). And we say that there is the “sixth sense,” meaning intuition or a hunch. But there is a physiological seventh sense that ...

One of the most persistent scientific mysteries over the past century has been exactly how some organisms seemingly have the ability to sense the Earth’s magnetic field. Despite several hypotheses, ...

A researcher may help answer why some animals have a magnetic 'sixth' sense, such as sea turtles' ability to return to the beach where they were born. The researchers proposes that the magnetic sense ...

Researchers have isolated what are essentially tiny compass needles in the noses of rainbow trout that may explain these and many other animals' incredible ability to navigate across vast distances.
