GMOs and the Risk to Our Genetic Heritage

By Alex Taylor In 2001, high in the Sierra Norte de Oaxaca mountains of southern Mexico, UC Berkeley graduate student David Quist hiked along some of the world’s oldest cornfields. Quist was sampling cobs for DNA testing, and what he found kicked off a scientific firestorm and brought attention to a subtle threat to the future of global agriculture. In those ancient Mexican corn varieties, Quist detected the DNA signature of genetically modified organisms (GMOs). A living genetic repository Hike down those Oaxacan mountains and into village marketplaces, and you…

Robust Rice Varieties Cut Costs and Pollution

By Neha Jain @lifesciexplore Climate change coupled with our growing population is putting tremendous pressure on world food production, especially in developing countries. We need crops that use resources more efficiently. Scientists from China and Canada have identified “superstar” rice varieties that can reduce pollution and also save money spent by farmers on nitrogen fertilizers. “Anything we can do to reduce demand for nitrogen, both environmentally and for farmers in the developing world struggling to pay for it, is a significant contribution,” says Herbert Kronzucker,  distinguished professor at the University…
