The cross-blending of sensory input – called synesthesia – is normally limited to individuals with a relatively unique neurological condition. But a new vision technology, called the vOICe system, is aiming to treat blindness by translating images from a camera into audio signals. This technological sensory substitution shows evidence of rewiring the brains of the blind, restoring vision and improving their lives drastically.
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
