News bites: Cause of Ark. oil spill fingered, shrimp in ill health and more

ExxonMobil said an independent review found outdated welding was to blame for a March pipeline burst and oil spill in Arkansas, The Wall Street Journal reports.

The Journal also takes a look at a disease that's killing shrimp, which is pushing prices for the crustacean higher in the United States.

An expert panel said the way the U.S. is calculating damages for the 2010 Gulf of Mexico oil spill will not account for the disaster's full environmental impact, The Guardian reports.

Massachusetts Gov. Deval Patrick (D) said he'd back an independent scientific study on the effects wind turbines have on health, The Associated Press reports. Some people have expressed concerns that the motion and sound of blades can cause health issues.
