"A growing number of Americans want the United States to regulate greenhouse gas emissions as the largest oil spill in U.S. history helps boost interest in petroleum alternatives, a poll by two universities found on Tuesday."

"The government and university researchers confirmed Tuesday that plumes of dispersed oil  were spreading far below the ocean surface from the leaking well in the Gulf of Mexico, raising fresh concern about the potential impact of the spill on sea life."

"The White House made clear on Tuesday what had been assumed for months – that it does not like a resolution sponsored by Senator Lisa Murkowski, Republican of Alaska, that would thwart the Environmental Protection Agency’s ability to regulate greenhouse gases."

"The Agriculture Department will approve for broad use [Tuesday] a genetically modified soybean engineered to contain healthier oils, the opening salvo in a biotech oil fight between DuPont Co. and its rival, Monsanto Co."

"A vote in the U.S. Senate to stop the Environmental Protection Agency from going it alone in battling carbon dioxide emissions will fail this week without new last-minute support, according to congressional and private-sector sources."

"A nuclear reactor where a hidden leak caused near-catastrophic corrosion in 2002 has experienced a second bout of the same problem."

"On Monday, BP said a cap was capturing 11,000 barrels of oil a day from the well. The official government estimate of the flow rate is 12,000 to 19,000 barrels a day, which means the new device should be capturing the bulk of the oil. But is it? With no consensus among experts on how much oil is pouring from the wellhead, it is difficult -- if not impossible -- to assess the containment cap’s effectiveness."

"BP, the very company responsible for the oil spill that is already the worst in U.S. history, has purchased several phrases on search engines such as Google and Yahoo so that the first result that shows up directs information seekers to the company's official website."
