Bad news from the Gulf: BP is reporting problems with the giant containment dome that was lowered to the ocean floor to save the day. Workers had to pull it off a blown well—at least temporarily—because of a buildup of ice crystals inside the 100-ton contraption, reports AP. It's still on the seafloor, just off to the side of the well now, and they'll study the problem to see whether it makes sense to try again. (More Gulf oil spill stories.)
