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
21-Mar-2007 From Russia with love
Ensuring that hydrogen-burning
engines are explosion-proof is one of
the barriers to establishing a hydrogen
economy. A tiny Russian-designed
hydrogen sensor that can quickly detect
and warn of a gas leak may be one of the
technologies to help catapult the world
into the hydrogen age.
9-Mar-2007 PNNL receives national safety award
Pacific Northwest National
Laboratory has been recognized as
one of America's Safest Companies
as featured in Occupational Hazards
magazine's November 2006 issue. Each
year, the honor is given to a group
of companies that demonstrate their
management-supported safety processes,
involvement from staff and innovative
solutions to safety challenges.
4-Dec-2006 PNNL introduces savvy new information tool
The Pacific Northwest National Laboratory has a
new Web site that offers a vast array of information,
both relevant and easy to access. Paired with Google
search technology, the site is highly visible and provides
unencumbered avenues to information on PNNL science
and technology and their applications.
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 ScalaBLAST solves problems in record time
Scientists are dedicated to making
discoveries that influence our world, but making these discoveries takes time. It took Albert Einstein 16 years to express his general theory of relativity. Benjamin Franklin was first introduced to electricity experiments on a trip to Boston in 1746, but his famous lightning rod experiment
didn't occur until six years later -- and he knocked himself unconscious more than once in the process.
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.
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.
8-Aug-2006 Jefferson Lab's newest cluster computer takes shape
Unlike a regular computer -- whose "brain" consists of one or perhaps two processors -- a cluster computer's brain can contain hundreds or even thousands of individual processors, called nodes -- all wired together. To solve a problem, the cluster splits the problem into parts, and each node computes its designated part and shares the result with other nodes to produce the final solution.
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.
