Portion of oil enters loop

Federal scientists say a small portion of the oil slick in the Gulf of Mexico has entered the powerful loop current that will take it around the tip of Florida and up the east coast. The oil from the leaking well has generally stayed away from shorelines so far, save for parts of Louisiana. In a bid to stem the flow, officials from BP plan to shoot drilling mud into the Deepwater Horizon well, perhaps Sunday. (Source: Mobile Press-Register, Sun Herald, 05/19/10 and 05/20/10) An explosion April 20 at the Deepwater Horizon drilling rig killed 11 workers and left an uncapped well spewing oil. About 19 percent of Gulf is now closed to fishing. Several methods to stem the flow have failed, with the exception of the insertion of a siphon pipe that's capturing a portion of the oil.
