By Richard Nunnally, Richmond Times-Dispatch, Va. Sep. 15--Q:I grow tomatoes every year and find those big green worms on them. Some have white lumps on their backs.

Gonzaga University biology professors Julie Beckstead and David L. Boose were recently awarded $247,000 in federal grants for a three-year study on pyrenophora semeniperda, a tiny, naturally occurring soil fungus that attacks the seeds of cheatgrass. Working with colleagues at...

In Washington, politicians have approved generous subsidies for companies that make ethanol. And just this week, President Bush arranged with Brazil's President Luiz Inacio Lula da Silva for...
