The Goldman Sachs executives are more than five hours into testimony before the Senate Subcommittee on Investigations. The investment firm is taking hits for not disclosing. Its interests were at times at odds with those of its clients. NPR's Yuki Noguchi reports.

From the outset, the senators posed their questions like accusations. Didn't the bank have a duty to tell its own clients that Goldman Sachs itself was shorting the mortgage market, betting on its decline? Arkansas Democrat Mark Pryor grilled Daniel Sparks, former head of the bank's mortgage division.

"Do you have responsibility to tell them what your positions are?"

"No."

"Why not?"

"Market makers are going to have positions all the time and that's not something that is a responsibility of a market maker to tell your counterparties at all times how you're positioned."

"But why not? Shouldn't there be more transparency there?"

The executives denied wrongdoing but expressed regret that many of the mortgage-related investments soured. Yuki Noguchi, NPR News, Washington.

President Obama is in Iowa on a tour focused on the rural American economy. Today, he stopped at an organic farm that supplies food for Iowa schools and businesses. Earlier in the day, he visited an Iowa plant that builds wind turbines. It was closed a few years ago, but recently it reopened. The president claimed credit, saying money from the stimulus law passed last year helped the plant open again. Meanwhile, he also set up a commission to work on cutting the national debt. He announced the 18-member bipartisan group and its work to lay out ways to cut excessive spending and the growing national debt.

Emergency officials along the Gulf Coast are preparing for an environmental disaster if the massive oil spill reaches the shore. An oil rig exploded off Louisiana and sank last week. And NPR's Debbie Elliott reports workers are trying to contain the spill that is 600 miles in circumference.

The oil slick is growing despite ongoing clean-up efforts. Underwater, robotic submarines are trying to shut off the oil at its source. Northwest winds have helped to keep the spilled oil offshore, but forecasters say the wind will shift out of the south later this week. That could push the slick closer to the northern Gulf Coast. Emergency officials from Venice, Louisiana to Pensacola, Florida are putting in place response plans for shoreline impacts which could threaten wildlife, tourism and fisheries. Republican Governor Charlie Crist of Florida says the offshore accident has him rethinking his position on oil and gas development off his state's coast. He says "if this doesn't give somebody pause, there's something wrong". Debbie Elliott, NPR News, Orange Beach, Alabama.

A test that measures calcium buildup in the arteries can help doctors better predict who's at risk for heart disease. NPR's Patti Neighmond reports on the study in the Journal of the American Medical Association.

Researchers already knew that screening for calcification in arteries of the heart could predict who might get heart disease and suffer a heart attack and who wouldn't, but they didn't know how much the calcium score increased the accuracy of that prediction. In the study, researchers from Northwestern University analyzed the risk for over 5,800 men and women of various ethnic backgrounds. They looked at traditional risk factors like age, gender, smoking, blood pressure, cholesterol and their ethnicity. For one group, they added a coronary calcium score which is determined by a cardiac CT scan. They found the score added significantly to prediction of heart disease. Even so, they suggest more research and an editorial urges caution based on cost and radiation exposure. Patti Neighmond, NPR News.
