• DES MOINES, Iowa (AP) -- Cattle are being bred with genes from their African cousins who are accustomed to hot weather. New corn varieties are emerging with larger roots for gathering water in a drought. Someday, the plants may even be able to "resurrect" themselves after a long dry spell, recovering quickly when rain returns.
• Across American agriculture, farmers and crop scientists have concluded that it's too late to fight climate change. They need to adapt to it with a new generation of hardier animals and plants specially engineered to survive, and even thrive, in intense heat, with little rain.
• "The single largest limitation for agriculture worldwide is drought," said Andrew Wood, a professor of plant physiology and molecular biology at Southern Illinois University.
• On his Kansas farm, Clay Scott is testing a new kind of corn called Droughtguard as his region suffers through a second consecutive growing season with painfully scarce precipitation.
• "These are products I really need," Scott said. "I couldn't be any happier that they are working on these products."
