Study identifies a new type of diurnal effect for cosmic ray-boosted dark matter

Over the past few decades, astrophysicists and cosmologists have gathered various observations hinting at the existence of dark matter (DM), a type of matter that does not absorb, reflect or emit light, and thus cannot be detected using conventional techniques for observing electromagnetic radiation. While physicists have predicted its existence based on astrophysical and cosmological observations, so far, DM has never been observed experimentally.
