Now Playing: 2-1-13 Marketplace Morning Report

This morning, the Labor Department is set to deliver its all important monthly jobs report. Economists expect roughly 155,000 jobs were created in the U.S. in January, and that the unemployment rate will stay at 7.8 percent. Later on today, at the White House, energy pioneer John Goodenough, a physicist, will receive the National Medal of Science. Goodenough helped develop the lithium ion battery that is used in cars, phones, and Boeing's new 787 Dreamliner. He discusses why the Dreamliner batteries have had so many problems. And, the Dow is off to its strongest start since 1994, up six percent in January. Some economists think this is because individual investors have returned to the market.
