In 1999 Gregory V. Hoppa, the late Randy Tufts, and a team of planetary scientists from the University of Arizona went a long way toward cracking the code, positing that the most mysterious fault lines identifiable on Europa — the wave-form-like "arcuate" fractures spiraling eerily across the crystalline landscapes near its poles — are almost certainly a result of Jupiter's shifting tidal pull on subsurface water.

Brain scans of 10 tone-deaf subjects — people who couldn't differentiate between or produce sounds of various pitches — revealed that they had many fewer fibers in the arcuate fasciculus, the pathway that connects the frontal and temporal lobes of the brain, than did a control group.
In nine of the 10 tone-deaf subjects, the researchers could detect no arcuate fasciculus in the right hemisphere at all.
