It's been 100 days since oil began leaking into the Gulf of Mexico. We look at that story and bring you this morning's headlines.

Biomechanical researchers analyzed 100 years of athletes' heights, weights and running and swimming records, and demonstrated how the placement of one's center of gravity affects one's athletic performance. No big deal, right? People got jumpy, however, when the International Journal of Design & Nature and Ecodynamics published the paper: “The Evolution of Speed in Athletics: Why the Fastest Runners are Black and Swimmers are White.”

People go to great lengths to fabricate military service. 4 out of 5 people claiming they served in Vietnam did not. Pulitzer Prize winning historian Joseph Ellis was famously exposed in 2001 for claiming to have served in Vietnam although he never even went. The Stolen Valor Act, a 2006 law which made it a federal misdemeanor to wear, manufacture or claim unearned military medals, was recently ruled unconstitutional by a Denver judge. But what drives people to lie about military service?

Deep within the 2,300 page legislation on financial reform that President Obama signed into law last week is a provision that pertains to the Democratic Republic of Congo. The new financial regulation law will require thousands of U.S. companies to disclose whether their products contain minerals from rebel-controlled mines in Congo. Many of these minerals, like tin, tungsten, gold and tantalum end up in our laptops, cell phones and other technologies; and these mines are helping to finance the ongoing conflict in Congo.

In 2003, Valerie Plame Wilson went from being an undercover CIA officer specializing in nuclear proliferation to a reluctant celebrity when members of the Bush administration outed her to the press. She has stayed mostly out of the public eye since, but now she’s lending her expertise and her voice to "Countdown to Zero," a new documentary about nuclear weapons by many of the same people who made "An Inconvenient Truth."

According to a new report by the Annie E. Casey Foundation looks at the increasing number of children living in poverty; headlines.

According to a new report released by the Annie E. Casey Foundation's KIDS COUNT, child poverty is on the rise in America. The report, which looked at data from 2008, shows that even before the recession hit, one million more children were living in households below the poverty line than in 2000. 

"That's a real warning sign for us," says Laura Beavers, national KIDS COUNT coordinator for the Annie E. Casey Foundation. "We are fully expecting that when the Census Bureau releases new data on child poverty this year, the child poverty rate is likely to climb above 20 percent."

The report also revealed the states with the highest ranking for overall well-being of children, and the states with the lowest rankings: New Hampshire ranked first, while Arkansas, Louisiana and Mississippi ranked in the bottom three.

It's been 100 days since the oil began gushing into the Gulf of Mexico. BP CEO Tony Hayward is being packed off to Russia for his bungling of the explosion's aftermath, but tainted managers aren't the only thing big oil is shipping overseas; they're also moving operations to countries with lax regulations.

There's growing concern about the national debt: currently a gulp-inducing $13 trillion... and counting. President Obama's National Commission on Fiscal Responsibility and Reform is tasked with coming up with proposals to begin solving the problem later this year. We speak with Sen. Judd Gregg (R-N.H.), ranking member on the Senate Budget Committee, and a member of the bipartisan deficit-reduction commission.

Yesterday the Utah Supreme Court overturned the conviction of polygamist sect leader Warren Jeffs on two counts of 'rape as accomplice' because of faulty juror instructions. The leader of the Fundamentalist Church of Jesus Christ of Latter Day Saints was convicted in 2007 for marrying 14-year-old Elissa Walls to her 19-year-old cousin, Allen Steed.

Arizona's controversial immigration law will come into effect tomorrow, unless a federal judge says otherwise. We take a look across the border to Loma Buenavista, Mexico. Sixty percent of the town's population is thought to have crossed the border into Arizona. The 800-person town depends on residents' relatives in the U.S. to send money back home; if their relatives leave, the town stands to be significantly affected by this new law. 

Earlier we spoke to the authors of a study that examines the links between races, body type and athleticism. The conversation spurred a wide range of thoughtful comments from our listeners.

Bea in Brooklyn emailed us to say:

Is it race or BODY type? If you're talking about long-limbed, thin runners, arent' there white, Asian, Indian, Middle Eastern and other people with that body type? If you're talking about long-torsoed swimmers, aren't there people of color with that body type?
