By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.

ORNL part of new project to study how tropical forests worldwide respond to climate change

DOE/Oak Ridge National Laboratory
Business Announcement

Researchers from the Department of Energy's Oak Ridge National Laboratory will play key roles in an expansive new project that aims to bring the future of tropical forests and the climate system into much clearer focus by coupling field research with the development of a new ecosystem model.

Collaborative vision, saving sight

DOE/Oak Ridge National Laboratory

A meeting to explore research collaborations between the Oak Ridge National Laboratory and the University of Tennessee set the foundation for a company that provides accessible and remote health screenings for patients concerned about diabetic related eye diseases.

Protein shake-up

DOE/Oak Ridge National Laboratory

For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers' conventional notion that proteins have a static and well-defined structure.

ORNL-led team demonstrates desalination with nanoporous graphene membrane

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

ORNL and SINAP cooperate on development of salt-cooled reactors

DOE/Oak Ridge National Laboratory
Business Announcement

Representatives from the Oak Ridge National Laboratory and the Shanghai Institute of Applied Physics are meeting at ORNL this week as part of an agreement between the two institutions to work together on the advancement of salt-cooled nuclear reactor technologies.

Part II, Tackling grand challenges in geochemistry: Q&A with Andrew Stack

DOE/Oak Ridge National Laboratory

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.

Graphene 'gateway' discovery opens possibilities for improved energy technologies

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Graphene, a strong, lightweight carbon honeycombed structure, only one atom thick, holds great promise for energy research and development. Recently scientists with the Fluid Interface Reactions, Structures, and Transport Energy Frontier Research Center, led by the US Department of Energy's Oak Ridge National Laboratory, revealed graphene can serve as a proton-selective permeable membrane, providing a new basis for streamlined and more efficient energy technologies such as improved fuel cells.
