After mastodons and mammoths, a transformed landscape

Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals -- including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers -- began their precipitous slide to extinction. And when their populations crashed, emptying a land whose diversity of large animals equaled…

Scientists make fundamental discovery to creating better crops

A team of scientists led by the Department of Energy's Oak Ridge National Laboratory have discovered the specific gene that controls an important symbiotic relationship between plants and soil fungi, and successfully facilitated the symbiosis in a plant that typically resists it. The discovery could lead to the development of bioenergy and food crops that…
