"Pregnant rats exposed to an industrial pollutant passed on a variety of diseases to their unexposed great-grandkids, according to a study published Wednesday."

"Rachel Carson wasn't someone you'd expect to spark a movement. She was a quiet, petite woman who grew up poor, lived most of her life with her mother and relished solitary walks along the beach, watching birds and fish. Yet 50 years ago Thursday, this marine biologist published Silent Spring, widely credited with spurring the modern environmental movement."

"Brace yourself for some shocking news: a new study on Friday found that the two major publications of Rupert Murdoch's News Corporation greatly mislead their audiences about climate change. The Union of Concerned Scientists combed six months of Fox News broadcasting and a year's worth of Wall Street Journal editorial pages for mentions of the science of 'climate change' and 'global warming,' then compared each claim to 'mainstream scientific understanding' of the topic at hand." They found 93% of the statements on Fox News were misleading and 81% of the statements on the Wall St. Journal's opionion pages were misleading.

"On June 4, 1963, less than a year after the controversial environmental classic 'Silent Spring' was published, its author, Rachel Carson, testified before a Senate subcommittee on pesticides. She was 56 and dying of breast cancer. She told almost no one. She'd already survived a radical mastectomy. Her pelvis was so riddled with fractures that it was nearly impossible for her to walk to her seat at the wooden table before the Congressional panel. To hide her baldness, she wore a dark brown wig."

Federal and state health officials say that pesticide spraying for adult mosquitoes has reduced risk of West Nile virus by killing specific percentages of mosquitoes. When confronted with Freedom of Information Act requests for the data to back up those claims, they do not seem to be able to find any.
