Magnetic cells

The nose of salmon can hold a secret about the possibility of returning to the burial place, even though they must spend the rest of their lives in the open sea.

Scientists have long argued that there are some forms of magnetic sensation that lie behind the ability of some creatures to admire the beauty, such as in the case of fish or species of birds that can migrate to / migrate. stay and finally turn home.

Now, a German researcher claims to have found single cells that react before the Earth's magnetic field.

According to Discovery, expert Stephan Eder of Ludwig-Maximilians University first gathered the cells he suspected were 'magnetic cells ', then placed them in the rotating magnetic field to determine whether they were whether or not to rotate.

The seven-colored salmon was chosen because in 1977, a researcher named Michael Walker identified what he called the nasal receptor of this fish, ie cells containing iron crystals.

Eder experts have confirmed the results of the study, but these cells are not easy to detect.

When he placed the tissue sample in a slowly rotating magnetic field, he found that only one of the 10,000 cells began to rotate in the same direction as the magnetic field.

The rare condition of magnetic cells is a reason, because these cells contain very strong magnetic properties, if placed together, they will interfere and reduce the sensitivity of the senses from the body, according to reported on PNAS.
