BP oil isn’t the only source of Gulf’s deep roaming plumes
During a June 8 briefing for reporters, a NOAA science officer described deep strata of water tainted with oil identified during a recent cruise in the Gulf of Mexico. The presumption was that anything they found would be plumes of oil spewed by the jet of hydrocarbons emanating from the BP well head. But the chemical fingerprinting of diffuse undersea clouds of oil at one sampling site was “not consistent with BP oil,” he pointed out.

July: When not to go to the hospital
Being admitted to the hospital is never a picnic. But when possible, schedule any therapeutic procedure for some month other than July. At least if you’ll be treated at a teaching hospital. That’s the conclusion of a new analysis that uncovered a cyclical spike across the nation in serious medication errors.
