Crops that produce more while using less water seem like a dream for a world with a burgeoning population and already strained food and water resources. This dream is coming closer to reality for University of Illinois at Urbana-Champaign researchers who have developed a new computer model that can help plant scientists breed better soybean crops.
A new technique to fight crop insect pests may affect different insect populations differently, researchers report. They analyzed RNA interference (RNAi), a method that uses genetic material to “silence” specific genes – in this case genes known to give insect pests an advantage. The researchers found that western corn rootworm beetles that are already resistant to crop rotation are in some cases also less vulnerable to RNAi.
To keep pace with the ever-increasing demand for renewable energy, forest management policy in the U.S. must evolve to address environmental sustainability issues, says Jody Endres, a professor of bioenergy, environmental and natural resources law at Illinois.
Brenna Ellison, a professor of agricultural and consumer economics, says the combination of a symbol and a numeric calorie count on a menu is the most effective way to influence patrons to select lower-calorie items.
It has been almost 20 years since the first genetically modified foods showed up in produce aisles throughout the United States and the rest of the world, but controversy continues to surround the products and their regulation.
