Bt: The lesson not learned
The more things change, the more they stay the same, as a Dec. 29 Associated Press report on genetically engineered corn notes. Like déjà vu, this news story on emerging resistance to Bt toxin — a fabulously effective and popular insecticide to protect corn — brings to mind articles I encountered over the weekend while flipping through historic issues of Science News.

Now much the same thing is happening again with Bt, its contemporary agricultural counterpart. Will we never learn?
