South-Africa-Rape

Dumisani Rebombo is no ordinary advocate for women's rights in South Africa. He is a rapist, who sought out his victim two decades after his brutal act to ask for forgiveness.He is all this in a nation where sexual assault has become so common that a woman in South Africa is more likely to be raped than learn to read. Sexual assaults rarely shock anyone anymore, though a video of a brutal gang rape of a mentally disabled teenager went viral on the internet last month. That touched a nerve. As the young suspects face their day in court, Rebombo spoke with CNN to tell his own story -- an extraordinary tale of violence, redemption and determination to change things in his homeland.

FEA-Cinco-de-Mayo-Origins

Cinco de Mayo -- the unofficial U.S. holiday long believed to have been imported, with celebratory beer, from Mexico -- isn't a Mexican holiday at all but rather an American one created by Latinos in the American West during the Civil War, according to new research by a California professor. Conventional thinking has long held that the holiday -- now a commercial juggernaut -- emerged from the mass migrations of the bloody Mexican Revolution of the 1910s or even during Chicano activism in the 1960s in California, University of California at Los Angeles Professor David Hayes-Bautista told CNN. But on the 150th anniversary of the holiday, Hayes-Bautista is announcing that he accidentally found the origins of Cinco de Mayo -- the 5th of May -- after poring through Spanish-language newspapers in California from the mid-1800s while working on another research project.

Turkey-Releasing-Captive-Dolphins

It's a risky venture, according to trainer Jeff Foster who tried to reintroduce "Free Willy" orca back into the wild more than a decade ago.
