Despite Lingering Drought, USDA Predicts A Flood Of Grain

Originally published on Fri February 22, 2013 2:51 pm

Economists at the U.S. Department of Agriculture, gazing into their crystal ball, see American farmers planting and harvesting huge amounts of corn, soybeans, and wheat this year.

Many a mom has reached for a glass of wine after a long day of tending children. But only fruit fly moms use their version of Chardonnay to guard their babies from harm.
