“Beauty is an ultimate value—something that we pursue for its own sake, and for the pursuit of which no further reason need be given.
Beauty should therefore be compared to truth and goodness”

Blue light-dependent human magnetoreception in geomagnetic food orientation
The Earth’s geomagnetic field (GMF) is known to influence magnetoreceptive creatures, from bacteria to mammals as a sensory cue or a physiological modulator, despite it is largely thought that humans cannot sense the GMF. Here, we show that humans sense the GMF to orient their direction toward food .
Our findings show that, as a group, starved men can sense the GMF during food consumption and use it to identify the direction in which food can be obtained,
The results show that blue light entering the eyes, the putative magnetoreception organ in humans, is essential for GMF-receptive food orientation. Given that birds demonstrated a magnetoresponsive orientation under light at wavelengths up to 571 nm , it is interesting that male subjects did not orient for wavelengths > 500 nm, warranting an investigation into the difference between birds and men.
