"Now, for the first time ever, scientists from the University of Tokyo have directly observed a key reaction hypothesised to be behind birds', and many other creatures', talents for sensing the direction of the planet's poles.
Importantly, this is evidence of quantum physics directly affecting a biochemical reaction in a cell – something we've long hypothesised but haven't seen in action before.
Using a tailor-made microscope sensitive to faint flashes of light, the team watched a culture of human cells containing a special light-sensitive material respond dynamically to changes in a magnetic field."
"Researchers in Japan have made the first observations of biological magnetoreception—live, unaltered cells responding to a magnetic field in real time. This discovery is a crucial step in understanding how animals from birds to butterflies navigate using Earth's magnetic field and addressing the question of whether weak electromagnetic fields in our environment might affect human health."
