Need to Know, June 24, 2011: Combating IEDs, the ramifications of the Wal-Mart case, the science of happy marriages

Improvised explosive devices, or IEDs, have been a trademark of the wars in Iraq and Afghanistan. Over the past decade, they have been used with increasing frequency in combat and are responsible for hundreds of deaths and casualties. This week on Need to Know, we explore the inner workings of a little-known military organization and its $17 billion campaign to combat IEDs in Iraq and Afghanistan.

We also speak with legal analyst Jami Floyd on the long-term impact of the Supreme Court’s decision to dismiss the class action suit against Wal-Mart over discrimination of female employees. This week, Floyd wrote about the Wal-Mart case, arguing that despite this latest setback, the women still could prevail in court. We also interview former Deputy Defense Secretary Celeste Ward Gventer about President Obama’s announcement on troop withdrawals from Afghanistan.

And: What makes a happy marriage happy? We delve into some recent research on the science of marital satisfaction, including the health benefits that come with happy marriages.
