Magnetic Sixth Sense?

An article I found: Humans may have a sixth sense after all, suggests a new study finding that a protein in the human retina, when placed into fruit flies, has the ability to detect magnetic fields.

The researchers caution that the results suggest this human protein has the capability to work as a magnetosensor; however, whether or not humans use it in that way is not known.

"It poses the question, 'maybe we should rethink about this sixth sense,'" Steven Reppert, of the University of Massachusetts Medical School, told LiveScience. "It is thought to be very important for how animals migrate. Perhaps this protein is also fulfilling an important function for sensing magnetic fields in humans."

Past research has suggested that in addition to helping animals such as sea turtles and migratory birds navigate, the ability to detect magnetic fields could help with visual spatial perception. Reppert said to picture a magnetic-field coordinate system overlaid on objects we view.

"It may aid how animals perceive how objects are in time and space in a way we haven't thought about before," said Reppert, who is a neurobiologist.

Animals' magnetic sense is thought to rely on special proteins called cryptochromes, which are also found in the human retina. While past behavioral research has suggested humans can't sense magnetic fields, with studies showing such a capability remaining controversial, there is evidence that geomagnetism affects the light system in our eyes.

To see if humans perhaps possessed this other sense, Reppert and his colleagues tested wild fruit flies, with their cryptochromes intact, and those that had their own cryptochromes replaced with the human version of the protein.

They placed the fruit flies into a T-shaped maze, with each arm equipped with a coil wrapped in such a way that when a current was sent through it, the coil became magnetized. The team varied which side was magnetized and its strength, which went up to eight times that of Earth's magnetic field.

The flies with the human cryptochromes showed sensitivity to the magnetic fields - either avoiding them as they might naturally do if not acclimated to the magnetism, or showing a preference for the magnetized arm of the maze when trained with sugar rewards to go toward the magnetic field.

The Aristolean classification of senses hasn't been accepted for some time. There are approaching 20 different senses, maybe even more. Magnetic field detection has been classified as a sense for a while, however, it is a new discovery that humans have limited degree of it.

What evidence? What is 'light system'?
The Holy Quran 29:19-20

See they not how Allah originates creation, then repeats it: truly that is easy for Allah.

Say: "Travel through the earth and see how Allah did originate creation; so will Allah produce a later creation: for Allah has power over all things.

I don't think this is the 'sixth sense' that has been pretty much proven... but something else.
I am voting for Innomen because of his intelligence, common sense, humility and the fact that Juggle appears to listen to him. Any other Presidential style would have a large sub-section of the site up in arms. If I was President I would destroy the site though elitism, others would let it run riot. Innomen represents a middle way that works, neither draconian nor anarchic and that is the only way things can work. Plus he does it all without ego trips.
