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.
Tunisian protesters attacked the U.S. Embassy recently in response to the anti-Muslim video Innocence of Muslims. This was just the latest of several episodes in which hard-line Muslims have acted out publicly to what they see as attacks on their religion.
Two weeks after the attacks that killed the U.S. Ambassador to Libya and three other Americans, there is still confusion about what exactly happened and whether the United States might have prevented the tragedy. Critics of the Obama administration accuse the White House of dissembling about the attack. NPR's Dina Temple-Raston talks to Melissa Block.
Scientists have discovered that a mouse found in Africa can lose large patches of skin and then grow it back without scarring, perhaps as a way of escaping the clutches of a predator.
The finding challenges the conventional view that mammals have an extremely limited ability to replace injured body parts. There are lizards that can regrow lost tails, salamanders that can replace amputated legs, and fish that can generate new fins, but humans and other mammals generally patch up wounds with scar tissue.
