With the rise in superbug occurrences at hospitals, Audie Cornish talks with Tara Palmore, deputy hospital epidemiologist and infectious disease physician at the National Institutes of Health, about how healthcare facilities are changing practices to help stem the spread of the drug-resistant bacteria.

Forest elephants in central Africa are being slaughtered in record numbers. The most comprehensive study ever, done over a decade, shows that poaching — mostly for the Asian market for ivory — has put the forest elephant on the brink of extinction. Poaching has overcome laws and treaties to protect the species. The U.S. government and wildlife groups are struggling to slow the killing. A meeting in March of the Convention on International Trade in Endangered Species will focus on solutions. Audie Cornish talks to Christopher Joyce.

He's also offered Egypt's Islamist government $190 million to avert a budget crisis and he's warning Iran that talks can't go on indefinitely.

Democratic Senators Harry Reid and Mo Cowan have joined Republicans John McCain and Representative Peter King to call for the pardon of former heavyweight boxing champ Jack Johnson. He was the first black fighter to win that title, in 1908. Another win in 1910 sparked race riots nationwide, and his relationships with white women only added to the controversy. He was convicted of taking women across state lines for "immoral purpose." Audie Cornish has more.
