Remember the promises made by Monsanto that genetically-modified (GM) crops would bring higher yields and a better quality of life to the world? A recent study put forth by anthropologists from Washington University (WU) in St. Louis has revealed that Bt cotton, a type of GM cotton that produces its own insecticide, is causing significant problems for sustainable farm management, while offering little to no actual increases in yield.
Why is the USDA once again putting biotechnology before human safety?
And then in December, a federal judge ordered that 258 very important acres of genetically modified sugar beets be destroyed. Judge Jeffrey White ruled that the crops be destroyed because the risk of gene contamination in Oregon's Willamette Valley was so great. This was a step in the right direction no matter how small the step.
Birds living around the site of the Chernobyl nuclear accident have 5% smaller brains, an effect directly linked to lingering background radiation. The finding comes from a study of 550 birds belonging to 48 different species living in the region, published in the journal PLoS One.
Brain size was significantly smaller in yearlings compared to older birds. Smaller brain sizes are thought to be linked to reduced cognitive ability. The discovery was made by a team of researchers from Norway, France and the US led by Professor Timothy Mousseau from the University of South Carolina, US, and Dr Anders Moller from the University of Paris-Sud, France.
A widespread drought in the Amazon rainforest last year caused the "lungs of the world" to produce more carbon dioxide than they absorbed, potentially leading to a dangerous acceleration of global warming. Scientists have calculated that the 2010 drought was more intense than the "one-in-100-year" drought of 2005.
They are predicting it will result in some eight billion tonnes of carbon dioxide being expelled from the Amazon rainforest, which is more than the total annual carbon emissions of the United States. For the second time in less than a decade, the earth's greatest rainforest released more carbon dioxide than it absorbed because many of its trees dried out and died.
The Environmental Protection Agency is setting the first drinking water standard for a toxic rocket fuel ingredient linked to thyroid problems in pregnant women and young children, the Obama administration is to announce on Wednesday.
Environmental Protection Agency administrator Lisa Jackson will say that setting the standard will spark new technologies to clean up drinking water, according to a press release obtained by The Associated Press. Based on monitoring conducted from 2001 to 2005, 153 drinking water sources in 26 states contain perchlorate. The standard could take up to two years to develop.
In one of the most dramatic signs ever documented of how shrinking Arctic sea ice impacts polar bears, researchers at the U.S. Geological Survey in Alaska have tracked a female bear that swam nine days across the deep, frigid Beaufort Sea before reaching an ice floe 426 miles offshore.
The marathon swim came at a cost: With little food likely available once she arrived, the bear lost 22% of her body weight and her year-old female cub, who set off on the journey but did not survive, the researchers said.
The investigation comes days after the deaths of an estimated 100,000 fish in northwest Arkansas. Authorities suspect disease was to blame there, a state spokesman said.
"The affected fish are almost exclusively juvenile spot fish, 3 to 6 inches in length," the Maryland department said. A recent survey "showed a very strong population of spot in the bay this year. An increased juvenile population and limited deep water habitat would likely compound the effects of cold water stress."
