A federal court judge in New Orleans will hear argument for and against the temporary moratorium on deepwater oil drilling. Companies seeking to overturn the ban say the government has no evidence that existing rigs are unsafe. The government says the moratorium is needed while experts evaluate the industry's safety procedures. We speak with Steve Mufson, finance and energy reporter for the Washington Post about why  hundreds of deep-sea rigs are still operating in the Gulf of Mexico.

When Josh Fox was offered $100,000 for the natural gas drilling rights to his property in Pennsylvania, he resisted. Instead, he picked up a camera and traveled the country to find out more about what could happen on his land if he signed on the dotted line. His film, GASLAND, airs tonight on HBO. It tells the story of tap water that can burst into flames, animals that are losing their hair and hydraulic fracturing, or "fracing."  Under that process, millions of gallons of water, sand and chemicals are injected into the ground to break up rocks and release gas.  Fox says while in office, Vice President Dick Cheney worked to have "fracing" exempted from regulations in the Safe Drinking Water Act and the Clean Air Act, even though the chemicals used can be toxic.

We speak with Fred Knapp, reporter for NET Radio, Nebraska's NPR news station.

The leading cause of HIV infection in children is transmission from mother to child, or what's known as vertical transmission. In 2001, governments around the world pledged to reduce transmission by half.  But our guest, Paula Donovan, of the advocacy group Aids Free World, argues that rates haven't dropped significantly in the developing world, and that has to do with the fact that too little attention is paid to the health of the mother. Her organization is calling for more attention to the health of the mother, whose survival is critical for the health of the child.
