(AP Photo/BP PLC) (Newser) – It's "top kill," take two. BP has resumed pumping dense mud into its blown-out well in the Gulf, reports CNN. The company began the procedure yesterday but said it suspended it about midnight to assess progress. Despite some positive reports to the contrary this morning, the initial efforts failed to stop the flow of oil. The company says it won't be able to gauge success until tomorrow or the weekend.
