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.

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.
And let's go next to West Africa, where logging rights to more than 60 percent of Liberia's virgin rainforests have been granted to forestry companies since President Ellen Johnson Sirleaf came to power six years ago. A British advocacy group says the majority of those contracts are unregulated and warns of fraud and mismanagement. The government of Liberia says it is commissioning a full-scale investigation.
Violent protests in eastern Libya have set in motion a movement to take back the nation from dozens of militias born from the revolt against strongman Moammar Gadhafi. Since the dictator's demise, Libya has been beholden to men with guns.
