Bacteria tracked feeding nitrogen to nutrient-starved plants
An international team of researchers, including three from Brookhaven National Laboratory, tracked nitrogen as soil bacteria pulled it from the air and released it as plant-friendly ammonium. This eco-friendly process -- called biological nitrogen fixation -- substantially promoted growth in certain grass crops.

'Explosive' atom movement is new window into growing metal nanostructures
Scientists at the US Department of Energy's Ames Laboratory expected to see slow, random movement when they dropped lead atoms on a lead-on-silicon surface. 'But what we saw? BOOM! Fast, explosive and organized!' said Michael Tringides, Ames Laboratory physicist. The unusual atom movement may represent a new way to grow perfect, tiny metal nanostructures for nanostransistors, nanoswitches, and nanomagnets.

Part II, Tackling grand challenges in geochemistry: Q&A with Andrew Stack
In this Q&A Andrew Stack, a geochemist at the Department of Energy's Oak Ridge National Laboratory, advances understanding of the dynamics of minerals underground. Stack and his team make discoveries that will help to improve our understanding of a wide range of energy-related issues, such as geologic storage of carbon dioxide, oil and gas discovery and development, and remediation of toxic contaminants. His current research spans three disciplines -- geology, chemistry and computing.
