Mixing it up
Article Abstract:
One chemical alone may not do harm in low doses, however, in conjunction with a few others, even in doses that are individually safe, it can inflict serious harm. New research in frogs shows that a mixture of nine chemicals found in a seed-corn field in York County, Nebraska, killed a third of exposed tadpoles and lengthened time to metamorphosis by more than two weeks for the survivors.

Original mystery: Bt pesticide may not really be an insect killer
Article Abstract:
The toxic crystal produced by Bacillus thuringiensis (Bt) is widely used as a pesticide for preventing crop pests. A study suggests that Bt works in conjunction with gut bacteria, perhaps to produce septicemia, but the exact mechanism remains unknown.
