A proposed study of people in northern Pennsylvania could help resolve a national debate about whether the natural gas boom is making people sick.
The study would look at detailed health histories on hundreds of thousands of people who live near the Marcellus Shale, a rock formation in which energy companies have already drilled about 5,000 natural gas wells.
If the study goes forward, it would be the first large-scale, scientifically rigorous assessment of the health effects of gas production.
In Ohio, a new congressional district that stretches along Lake Erie between Toledo and Cleveland has become a political portrait of polarized America.
The 9th District is one of the results of Ohio's loss of two representatives following the last census. The primary for the redrawn district pitted two longtime Democratic incumbents against each other. Now the victor, Rep. Marcy Kaptur, is taking on a Republican known for his role in the 2008 presidential election.
