Tunisia was the birthplace of the Arab Spring last year, and many regard it as the most Western-looking nation in the Arab world. Yet it's also waging a roaring debate over how to define freedom of expression in an evolving society.

NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from Earth (right).
NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.
