Sixth Sense: Scientist Claims Humans Can Detect Earth’s Magnetic Fields


A US scientist has claimed to have found evidence of a “sixth sense” in humans that can detect the Earth’s magnetic fields.

Joe Kirschvink, from the California Institute of Technology, says his experiment can also be “repeated and verified”, something research on magnetoreception has never been able to do before.

The trial, which involved just 24 people builds on a 2016 study that suggested other mammals, including dogs, foxes and primates have “magnetic sensors” in their eyes.

This previous research, undertaken by the Max Planck Institute and published in Nature Scientific Reports, found animals including “dogs, wolves, bears, foxes, badgers, orangutans and macaques” have the field-sensing molecule cryptochrome 1a present in their retinas.

How exactly this works, however, has been up for debate. While some argue cryptochrome is responsible for the sense, others say magnetite receptor cells act as “compass needles”. It is this second theory that Kirschvink claims is responsible for the “sixth sense”.

For Kirschvink’s study, participants were asked to sit in the pitch black in a Faraday cage, a structure that screens out “electromagnetic background noise” with wire coils. Once in the cage, they were exposed to “a pure magnetic field” and nothing else.

Using an EEG, Kirschvink monitored whether participants’ brains responded to changes in magnetic strength. When the magnetic field was “rotating counterclockwise… there [was] a drop in alpha waves”, suggesting participants’ brains were firing “in response to the magnetic field”.

Kirschvink is undergoing further research.
