Edible Flu Vaccine testing in Corn crops

AMES, IOWA — Iowa State University researchers are putting flu vaccines into the genetic makeup of corn, which may someday allow pigs and humans to get a flu vaccination simply by eating corn or corn products.
"We're trying to figure out which genes from the swine influenza virus to incorporate into corn so those genes, when expressed, would produce protein," said Hank Harris, professor in animal science and one of the researchers on the project. "When the pig consumes that corn, it would serve as a vaccine."
This collaborative effort project involves Mr. Harris and Brad Bosworth, an affiliate associate professor of animal science working with pigs, and Kan Wang, a professor in agronomy, who is developing the vaccine traits in the corn.
According to the researchers, the corn vaccine would also work in humans when they eat corn or even corn flakes, corn chips, tortillas or anything that contains corn,
‘Superweed’ explosion threatens Monsanto heartlands

“Superweeds” are plaguing high-tech Monsanto crops in southern US states, driving farmers to use more herbicides, return to conventional crops or even abandon their farms.
The gospel of high-tech genetically modified (GM) crops is not sounding quite so sweet in the land of the converted. A new pest, the evil pigweed, is hitting headlines and chomping its way across Sun Belt states, threatening to transform cotton and soybean plots into weed battlefields.
In late 2004, “superweeds” that resisted Monsanto’s iconic “Roundup” herbicide, popped up in GM crops in the county of Macon, Georgia. Monsanto, the US multinational biotech corporation, is the world’s leading producer of Roundup, as well as genetically engineered seeds. Company figures show that nine out of 10 US farmers produce Roundup Ready seeds for their soybean crops.
Superweeds have since alarmingly appeared in other parts of Georgia, as well as South Carolina, North Carolina, Arkansas, Tennessee, Kentucky and Missouri, according to media reports. Roundup contains the active ingredient glyphosate, which is the most used herbicide in the USA.
How has this happened? Farmers over-relied on Monsanto’s revolutionary and controversial combination of a single “round up” herbicide and a high-tech seed with a built-in resistance to glyphosate, scientists say.
