| Why People Believe in Conspiracies After a public lecture in 2005, I was buttonholed by a documentary filmmaker with Michael Moore-ish ambitions of exposing the conspiracy behind 9/11. “You mean the conspiracy by Osama bin Laden and al Qaeda to attack the United States?” I asked rhetorically, knowing what was to come.“That’s what they want you to believe,” he said. “Who is they ?” I queried. “The government,” he whispered, as if “they” might be listening at that very moment. “But didn’t Osama and some members of al Qaeda not only say they did it,” I reminded him, “they gloated about what a glorious triumph it was?” [More] rss.sciam.com |

Defusing the Methane Greenhouse Time Bomb Methane trapped in Arctic ice (and elsewhere) could be rapidly released into the atmosphere as a result of global warming in a possible doomsday scenario for climate change, some scientists worry. After all, methane is 72 times more powerful as a greenhouse gas than carbon dioxide over a 20-year timescale. But research announced at the annual meeting of the American Geophysical Union this December suggests that marine microbes could at least partially defeat the methane "time bomb" sitting at the bottom of the world's oceans.The conventional wisdom for decades has been that methane emanating from the seafloor could be consumed by a special class of bacteria called methanotrophs. It has long been known, for instance, that these organisms at the bottom of the Black Sea consume methane produced in its deep oxygen-free waters. [More] rss.sciam.com |

A visit with people affected by the largest industrial spill in American history Editor's Note: Expedition Blue Planet , led by Jacques Cousteau's granddaughter Alexandra Cousteau, is traveling 14,500 miles of road over 138 days to investigate and film some of North America's most pressing water-use and management stories. Each week expedition members will file a dispatch from the field for Scientific American until the expedition concludes on November 12 in Washington, D.C. This is their second blog post. "Do you know what the largest industrial spill in American history is?" Alexandra Cousteau asked the residents of Kingston, Tenn., today.
