1. Scientists have finally figured out brain freeze

    Using diagnostic imaging to monitor blood flow in subjects’ heads, researchers had 13 healthy participants sip ice water (sadly, not ice cream) through a straw pressed against the upper palate. Subjects were told to raise their hands when the headache hit, and then raised them again when the pain went away. 

    Researchers discovered that consuming something cold causes “an abrupt increase in blood flow to a major artery in the brain,” which is subsequently followed “by the familiar headache-like pain.” When the artery constricts again after the sudden rush of blood, the pain stops. 

    They hope to use their findings to help treat migraines
