Heating releases cookware chemicals
Nonstick coatings on fry pans and microwave-popcorn bags can, when heated, release traces of potentially toxic perfluorinated chemicals.

Aquatic Non-Scents
Many common pollutants appear to be jeopardizing the survival of fish and other aquatic species by blunting their sense of smell.

Counterintuitive Toxicity
Toxicologists risk missing important health effects, both good and bad, if they don't begin regularly probing the impacts of very low doses of poisons.
- Agriculture
Cloned Meat and Milk Are Safe, but They Won’t Hit Stores Soon
A Food and Drug Administration analysis concludes that food from cloned animals is safe, but the effort and expense involved in creating these animals means that products from them won't be in markets anytime soon.

Natural Hazards
The U.S. Geological Survey has launched a new Web site about the threat of natural disasters. It provides seven easy-to-understand fact sheets on earthquakes, floods, hurricanes, landslides, tsunamis, volcanoes, and wildfires. The site also highlights resources and information available from the USGS and provides links to individual hazards Web pages for more detailed information. Go […]
- Agriculture
Big footprints
Livestock production carries surprisingly high, and largely hidden, environmental costs.

Yes, it’s asbestos
Federal mineralogists have corroborated earlier evidence that Sierra-foothills communities around Sacramento, Calif., are built atop soils naturally laced with asbestos.

Scraping the bottom
A survey of deep waters in western Lake Superior has revealed the tracks left by massive icebergs scraping bottom there during the last ice age.

Glaciers give major boost to sea level
The ongoing disappearance of glaciers and other small ice masses worldwide makes a larger contribution to sea level rise than the melting of ice sheets on Greenland and Antarctica does.
