Arsenic | featured news

Consumer Reports is calling on the Food and Drug Administration to set standards for how much arsenic can be allowed in rice after finding the potential toxin in almost every rice product it tested. FDA is running its own tests and says it would be premature to set standards or to urge consumers to change their eating habits. Rice producers say there's no documented evidence of health harm from arsenic in rice grown in the United States.

The discovery of a strange bacteria that can use arsenic as one of its nutrients widens the scope for finding new forms of life on Earth and possibly beyond.
