Global climate change research at Brookhaven
BNL scientists are simulating the atmosphere of the mid-21st century to see how increased levels of carbon dioxide and other trace gases may affect various ecosystems.

World-class climate modeling
Some of the world�s largest global climate models are being run on ORNL�s supercomputers, providing insights for national and international assessments of the effects of global warming caused by human activities.

New projects to explore 'breakthrough' ideas for capturing, storing carbon gases
As part of its efforts to develop "breakthrough" approaches for reducing the threat of global climate change, the Department has added three new projects to develop ways to capture carbon dioxide released from power plants and safely prevent it from entering the atmosphere.

Atmospheric aerosols found to brighten clouds
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Purdue University combine satellite data with model calculations to study whether atmospheric aerosols increase the brightness of clouds enough to have a potential impact on climate. Higher reflectivity of brighter clouds may result in global cooling, partially offsetting the greenhouse effect. The Brookhaven-Purdue study was reported in the February 19, 2002 issue of the Proceedings of the National Academy of Sciences.

Giving an EDGE to sustainable design
Researchers at Pacific Northwest National Laboratory have developed tools for sustainable design, a term that describes a systematic approach to ensuring that facilities, products and processes are addressing the "triple bottom line" - the environment, economics and social equity.

Assessing every breath you take
Researchers at Pacific Northwest National Laboratory have developed a sophisticated modeling system that assesses health and safety impacts of contaminated indoor air.

1-Mar-2002
Chemicals sign in
To improve analyses, Pacific Northwest scientists are developing a chemical kinetics chamber that tracks various chemical reactions in a controlled environment and provides information on the chemical signatures present.

New project to develop Web tool for analyzing air quality in Ohio River Valley
A new project in DOE's Fossil Energy program will compile massive amounts of air quality data collected over three years from half a dozen sampling stations and make the information available to researchers and regulators over the Internet. The web tool will be especially useful in future State actions to regulate microscopic PM2.5 particles.

Researchers reach to the skies to reveal the secrets of the stars
In 2003, Argonne scientists will analyze solar wind--single atoms and electrically charged particles from the sun--samples from NASA's Genesis mission in an effort to better understand how the planets formed and how the sun works. If successful, Genesis will become the first mission to return a sample of extraterrestrial material from beyond the moon. These samples will allow a precise measure of the elemental and isotopic composition of our most important star - the sun.

Biothreat detection takes concentration
Detecting potential biological threats is part of the Department of Energy's plan for homeland defense, and a new automated device developed by Pacific Northwest National Laboratory provides a key piece in biothreat detection technology.

Retaining and retrieving data more effectively
ORNL is a co-developer of and customer for the computer industry�s leading data-storage system in terms of capacity and transfer speed. The ORNL data-storage program also includes the Probe Storage Research Facility.

Backyard bacteria rout a stubborn toxin
In a portion of fractured basalt more than 200 feet below the surface of the Idaho National Engineering and Environmental Laboratory lies a highly concentrated sludge of the heavy liquid toxin trichloroethene (TCE). INEEL engineers are determined to rid the rock of the toxic solvent which, over more than 30 years, has gradually leached into the groundwater of the Snake River aquifer.

Gene-rich pufferfish DNA decoded
Although the Fugu genome contains essentially the same genes and regulatory sequences as the human genome, it carries those genes and regulatory sequences in approximately 365 million bases as compared to the 3 billion bases that make up human DNA. With far less so-called "junk DNA" to sort through, finding genes and controlling sequences in the Fugu genome should be a much easier task.

Structural biologists provides a close look at ribosomes
Biologists working at Argonne�s Structural Biology Center (SBC) recently examined components of these protein factories with X-ray crystallography at resolutions high enough to determine the position and interaction of individual atoms. These images are the culmination of four decades of work in elucidating how the ribosome creates proteins.

Award-winning gasoline reformer is a catalyst for change
Instead of spark plugs and cylinders, environmentally friendly fuel cell engines may be under the hoods of the cars of the future. But first, scientists must find a practical and economical way to supply the hydrogen gas needed to power them. Chemical engineers at Argonne have developed and patented a compact fuel processor that �reforms� ordinary gasoline into a hydrogen-rich gas to power fuel cells.

1-Sep-2001
Pumping up safety in refining gasoline
Researchers at Pacific Northwest National Laboratory have developed a new solid acid catalyst that may provide oil producers worldwide with a safer approach for refining unleaded gasoline with reasonably high octane.

An in-stream waste treatment technology
A waste storage lagoon at a Washington dairy is being converted into a waste treatment facility with the help of a new technology that enhances naturally occurring biological activity.

Laboratory wins four R&D 100 Awards
Four technologies developed by researchers at Pacific Northwest National Laboratory and their collaborators are on R&D Magazine's list of the 100 most significant technology developments for 2000.

Spectra library ready for check out
A new e-commerce site introduced by the William R. Wiley Environmental Molecular Sciences Laboratory at Pacific Northwest National Laboratory may provide information that can be used, for example, in monitoring trace gases in the atmosphere or in improving chemical processes to demonstrate compliance with government guidelines.

1-Jul-2001
Research partnership formed
Pacific Northwest National Laboratory and the University of Maryland have joined forces to advance the understanding of global climate change. The Joint Global Change Research Institute, announced in March 2001, will investigate the scientific, social and economic implications of climate change, both nationally and globally.

Grounding greenhouse gases
Moving carbon out of the atmosphere and storing it in the ground offers a promising approach to reducing greenhouse gases, principally carbon dioxide, in the atmosphere. Researchers at Pacific Northwest National Laboratory are exploring how different soil management practices affect the fungal activity in soils and how that relates to the soils' ability to store carbon.
