The pair of a Creta University physicist has found some kinds of biological magnetic recruiters used by various creatures and used for quantum restrictions or nearby. In a paper published in the Journal Prx Life, IK Kominis and E. Gkoudinakis, conversely, how to function with small animal magnetic sensing by placing borders on unknown quantum boundaries. Explains what you have shown about voyage capabilities.
Previous studies show that many creatures use the earth’s magnetic fields as navigation aid. For example, some sharks, fish, and birds use it to use it to cross long distances. Various animals have various types of magnetic sensors, such as radical pairs, guidance, and magnetite mechanism.
The radical pair works by detecting the correlation between electrons that is not adhered to a specific molecule. The guidance works by changing the energy in the magnetic field to electricity and detecting the charge. Magnetite -based magnetic sapations also include the movement or direction of small iron crystals in the body, like a compass created by humans.
Kominis and Gkoudinakis were interested in the range of such creatures based on the type of sensor. They began research because they focus on being able to judge the performance of magnetic sensors using three types of parameters: Volume, time, and uncertainty of the estimated magnetic field. They also noted that the parameters used to judge such a performance can be reduced to accommodate small sensors, but also have restrictions based on the plansk.
In order to judge the performance of a biological sensor, researchers are likely to work near this limit due to a very small amount of magnetic fields related to their small sizes. I pointed out. Rather than trying to measure such a parameter in some form, the pair started with quantum restrictions and worked to return to the unknown parameters.
They have discovered that at least two biological magnetic receptors related to chemical reaction detection of various animals are at the quantum limit of magnetic field detection or perhaps very close. Field sensing device.
