“Magnetic Alignment Enhances Homing Efficiency of Hunting Dogs,” eLife, June 16, 2020.

“The research suggests that the magnetic field may provide dogs (and mammals generally) with a ‘universal’ reference frame, which is essential for long-distance navigation.” From Hynek Burda's group in the Czech Republic. More here.

“A Magnetic Compass Aids Monarch Butterfly Migration,” Nature Communications, posted online June 24, 2013.

Open access. A “vulnerability to consider is the potential disruption of the magnetic compass in monarchs by human-induced [EM] noise.”

“A Sense of Mystery: Researchers from various disciplines are homing in on the mechanics of magnetoreception, an enigmatic sense that some animals use to navigate the globe.” The Scientist, August 1, 2013.

“Most researchers in the field agree that the compass sense is likely seated in cryptochromes within the eye, and many are convinced that there is another sense, most likely a signpost sense, passed through the trigeminal nerve and probably based on some sort of iron-containing, magnetism-sensing cells in beaks or snouts. Then there is [David] Dickman and [Le-Qing] Wu’s idea: that both of these abilities may rely on receptors in the inner ear.”

Birds do it, butterflies do it, and now we learn that people may do it too. A group at the University of Massachusetts Medical School led by neurobiologist Steven Reppert reports that humans can sense the Earth's magnetic field. The finding prompts the team to suggest "a reassessment of human magnetosensivitiy may be in order." Check out the story...
