Numerous prior posts have followed the growing understanding of what factors drive the Gulf of Mexico dead zone. It pretty much comes down to nutrient runoff into the Mississippi River and its tributaries (e.g., sewage, feedlots, agricultural fertilizers...

Traditionally, when one considers exposure to methylmercury, adverse impacts upon the brain and kidneys are foremost in any risk assessment. See, for example, http://www.atsdr.cdc.gov/toxfaqs/tf.asp?id=113&tid=24 . Given the state of the evidence...

For those of us acquainted with researchers examining VOC exposure to individuals from scented consumer products (for example, at U.C. Berkeley and at U.C. Medical Center in San Francisco), it comes as no surprise that there is a bouquet of VOC's...

Prior posts have noted the importance of providing clean water and sanitation services to the human population in order to lessen the impact of disease on human health and well-being. Now researchers are exploring how disease may impact human intelligence...
