22-Mar-2007 Balancing oil and environment... responsibly
As the price of oil continues to fluctuate
unpredictably and nears the brink of depletion,
pursuing unconventional oil supplies, such as oil
shale, oil sands, heavy oils, and oils from biomass and
coal, has become increasingly attractive. Of particular
significance to the American way is that our continent
has significant quantities of these resources.
22-Mar-2007 Biomarkers -- Transforming human health and the environment
it in the news
Anthrax discovered in the mail… SARs outbreak…
Norovirus outbreak… Potential for an avian flu
pandemic looms… Obesity and diabetes threaten
Americans' health… Demand for water on the
rise, while water quality falls. What do they have
22-Mar-2007 Digging into dirt -- Subsurface science at PNNL
Imagine drinking water that has
dripped through the sponge you've just
used to clean the breakfast dishes. This
is happening around the world. Rain
and snow pass through soil polluted
with pesticides, poisonous metals and
radionuclides into the underground
streams that supply rivers, lakes and
1-Dec-2006 A closer look at the Northwest hydro system
Pacific Northwest National
Laboratory brought together public and private utilities, technology vendors and research institutions from across the Northwest to gather insight into challenges and opportunities for the
region's power grid.
29-Nov-2006 Moving grid operations from minutes to seconds
In the last century, the electric power grid has grown from a
system that served one square mile in New York into a highlycomplex
interconnected system that serves all of North America.
Initially, individual local systems would connect to each
other to share resources and increase reliability.
17-Nov-2006 Technology improves food processing quality
Researchers at Pacific Northwest
National Laboratory have developed an
ultrasonic technology that could tell
food manufacturers if foreign objects
have fallen into their product long
before it reaches the consumer.
17-Nov-2006 Structural safety gets boost from new technology
An acoustic inspection technology
developed at Pacific Northwest National Laboratory may help users in the oil, gas and other industries decide if a metal structure can withstand normal operation. Using a newly developed ultrasonic measurement technology, PNNL
researcher Paul Panetta and his team can rapidly locate and characterize suspected damage associated with strained metal, which current technologies cannot do.
16-Nov-2006 Sometimes smaller is better
A research team from the Pacific Northwest National Laboratory, Oregon Health and Science University, University of Minnesota and the University of Idaho is studying the ability of nanoscale iron particles to reduce carbon tetrachloride, a common groundwater contaminant.
9-Nov-2006 US wind power industry tempers its 2006 forecast slightly
The American Wind Energy Association (AWEA) announced on October 24th that the U.S. wind energy industry remains on track to set a record for wind power installations this year, with U.S. wind generating capacity increasing by 2,750 megawatts (MW).
5-Oct-2006 ORNL's High Flux Isotope Reactor prepares to make 'cold' neutrons
The High Flux Isotope Reactor at the Department of Energy's Oak Ridge National Laboratory has passed a major milestone in its quest to become one of the world's leading sources of 'cold' neutrons for advanced scientific research. Once fully operational, the reactor will combine with the laboratory's Spallation Neutron Source to make Oak Ridge the world's center for neutron sciences.
20-Jul-2006 Detector Group builds imaging device for German Research Center
Jefferson Lab Detector Group members traveled to Heidelberg, Germany, to assemble and bring on-line a small-animal imaging device the group developed and built for the German Cancer Research Center. Work on the project began in June 2004. The device is similar other small animal imaging gamma cameras developed by the Detector Group; however, this imager design is based on a new concept developed by Vladimir Popov which resulted in highly improved detector performance.
29-Jun-2006 Fish-friendly solutions
Although turbines have generated power at hydroelectric dams for many years, not much is known about how water flowing through the turbines may harm fish. In efforts to design more "fish-friendly" turbines, Pacific Northwest National Laboratory researchers conducted laboratory experiments to examine the relationship between water velocities within the turbine chambers and injuries to fish.
27-Jun-2006 WSU and PNNL break ground on new facility
Washington State University and Pacific Northwest National Laboratory broke ground April 13, 2006, on the Bioproducts, Sciences, and Engineering Laboratory. The BSEL is a $24-million joint effort between WSU and PNNL. Located on the WSU Tri-Cities campus, researchers will use the laboratory to develop processes for converting low-value agricultural byproducts and residues into value-added chemicals for products like plastics, solvents, fibers, pharmaceuticals and fuel additives.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
