Republican Congressman Rodney Davis of Taylorville said he reluctatly supported a GMO food labeling measure as the clock winded down on Congress last week. This measure, which President Obama is expected to sign, would pre-empt other state laws, including one out of Vermont that Davis calls 'unscientifically based', and meant solely to boost the state's economy.

Illinois Congressman Rodney Davis toured biotech research facilities in his district Wednesday, confirming his support for continued research and development of geneticially modified foods.

Guest: Bruce Chassy.

Some people continue to worry about both the environmental impact and potential health effects of biotech foods. But are these crops really so different from those we've grown in the past? Will they help us meet the growing demand for food? Today on Focus, we're joined by Professor of Food Science Bruce Chassy to discuss the dafety of bioengineered crops.

Guest: Michael Hansen.

Today on Focus we'll look at the ways in which relations between corporations and universities have affected biotechnology research. The increasing attention paid to profitability in academic work, says Michael Hanson, has driven research in directions with high expected returns—and led it away from areas that might contribute to the greater good. He joins us today to explain how biotechnology has developed an emphasis on genetic engineering—profit—over agricultural ecology.
