Salmon swim thousands of miles out into the open ocean only later to return to the precise fresh water stream where they were born and a new study suggests that this navigational miracle, in part, is due to geomagnetic imprinting. That is, the salmon sense, remember, and later use a map of the Earth’s magnetic field in and around their home river inlet. Read more

As to tracing a mechanism for they have 'Geomagnetic Imprinting' for Salmon to the molecular level, it seems they have not traced that mechanism out yet but have merely traced the overall Salmon migratory patterns to the varying 'geomagnetic field drift'. ,,, Where we have a much better 'tracing out' of the molecular mechanism for migratory patterns is in birds:
Magnetic Compass of Birds Is Based on a Molecule with Optimal Directional Sensitivity - 2009 Excerpt: The avian magnetic compass has been well characterized in behavioral tests: it is an “inclination compass” based on the inclination of the field lines rather than on the polarity, and its operation requires short-wavelength light. The “radical pair” model suggests that these properties reflect the use of specialized photopigments in the primary process of magnetoreception; it has recently been supported by experimental evidence indicating a role of magnetically sensitive radical-pair processes in the avian magnetic compass. In a multidisciplinary approach subjecting migratory birds to oscillating fields and using their orientation responses as a criterion for unhindered magnetoreception, we identify key features of the underlying receptor molecules. http://www.cell.com/biophysj/retrieve/pii/S0006349509004688 This New Research Reveals One More Awesome Aspect of Pigeon Navigation - April 2012 Excerpt: The new research suggests that there must be, as yet undiscovered, magnetic field sensors in the bird’s inner ear which report compass readings to the brainstem. http://darwins-god.blogspot.com/2012/04/this-new-research-reveals-one-more.html Magnetic fields light up 'GPS neurons', scientists say - 27 April 2012 Excerpt: Researchers have spotted a group of 53 cells within pigeons' brains that respond to the direction and strength of the Earth's magnetic field.,,, Every neuron had its own characteristic response to the magnetic field, with each giving a sort of 3-D compass reading along the familiar north-south directions as well as pointing directly upward or downward. In life, this could help the bird determine not only its heading just as a compass does, but would also reveal its approximate position. Each cell also showed a sensitivity to field strength, with the maximum sensitivity corresponding to the strength of the Earth's natural field. And just like a compass, the neurons had opposite responses to different field "polarity" - the magnetic north and south of a field, which surprised the researchers most of all. ,,, "That's one of the beautiful aspects of what we've identified, because it shows how single brain cells can record multiple properties or complex qualities in a simple way." http://www.bbc.co.uk/news/science-environment-17855194 Quantum robins lead the way - January 21, 2011 by Pete Wilton Excerpt: Researchers have been investigating the mechanism which enables birds to detect the Earth's magnetic field to help them navigate over vast distances. This ability, known as magnetoreception, has been linked to chemical reactions inside birds' eyes. Now a team from Oxford University and Singapore believe that this 'compass' is making use of something called quantum coherence. In a forthcoming article in Physical Review Letters the team report how they anaylsed data from an experiment by Oxford and Frankfurt scientists on robins. The experiment showed that the magnetic compass used by robins could be distrupted by extremely small levels of magnetic 'noise'. When this noise, a tiny oscillating magnetic field, was introduced it completely disabled the Robins' compass sense which then returned to normal once the noise was removed - good news for robins which have to navigate on the long migration route to Scandinavia and Africa and back every year. In their analysis the Oxford/Singapore team show that only a system with components operating at a quantum level would be this sensitive to such a small amount of noise. http://phys.org/news/2011-01-quantum-robins.html

In the 1930s, British ornithologist Edmund Selous – fascinated by Starling flocking (mumuration) – attributed the tremendous variety of their formations to telepathy! ,,, I would say that the recent discovery of a 'non-local' (beyond space and time) 'quantum compass' for birds has made the overall idea of 'telepathic birds' not such a 'bird brain' idea after all.

I don't think there is a mystery to these creatures finding their ways. I think its all about powerful memory's. They simply remember their way back. Geomagnetic imprinting is just more memory operations. The error has been to equate memory with intelligence. I think to segregate memory from intelligence would explain mental retardation in people and creatures finding their way about earth. No big deal. They just remember.Robert Byers_{February 9, 2013

bornagain77 at #3 Sorry to deviate from the topic of this thread but I watch Dr. Ben Carson's speech and I totally liked it. And I realized that this is the kind of black president that I would like to have.InVivoVeritas_{February 9, 2013

Though salmon are surely a wonder, I think this following little guy takes the trophy for long distance navigation: Featherweight songbird is a long-distance champ - February 2012 Excerpt: A tiny songbird weighing just two tablespoons of sugar migrates from the Arctic to Africa and back, a distance of up to 29,000 kilometres (18,000 miles), scientists reported on Wednesday. http://www.physorg.com/news/2012-02-featherweight-songbird-long-distance-champ.html Notes: Fish & Dinosaur Evolution vs. The Actual Evidence - video and notes http://vimeo.com/30932397 Bird Evolution vs. The Actual Fossil Evidence - video and notes http://vimeo.com/30926629 An interesting side-note to this is that it is found that flying fish are remarkably similar to birds, and even jet airplanes, in many superior attributes of gliding ability: Flying Fish Glide as Well as Birds, Researchers Find - Sept. 2010 http://www.sciencedaily.com/releases/2010/09/100910082308.htm As well flying fish are 'surprisingly' unchanged in the fossil record for at least as far back as 95 million years: Flying Fish Fossil - pictures of 95 million year old fossil http://www.fossilmuseum.net/fishfossils/Excoetoides-minor/Excoetoides.htmbornagain77_{February 8, 2013
