Wild Peanut Genes
A decade ago, University of Georgia plant scientists David and Soraya Bertioli were living and working in Brazil when they began to wonder about peanut plants they encountered in different corners of the world with an astounding ability to withstand fungal diseases without the use of fungicides. The Bertiolis wondered if these different plants might all have something in common. Did they owe their natural resistance to a single genetic source?

Pigskin and Peaches
Georgia and South Carolina share a border, a passion for football and pride in their peaches. With the University of Georgia and Clemson University campuses separated by a mere 70 miles, the Bulldogs and Tigers began fighting it out on the football field in 1897, with the teams set to meet for the 65th time on Sept. 4. As pitched as the battle is on the football field, there’s an even deeper rivalry between the two states when it comes to their peaches.
