14-Jun-2007 Taming the hairy mushroom
Fungi (yeasts, molds and mushrooms) have gotten a bad rap over the years. They have been blamed for infecting food crops and represent some of the most universal and costly pathogens known to man -- both of
which overshadow the important contributions fungi make, such as providing critical agricultural nutrients and compounds for antibiotics.
11-May-2007 An ancient bathtub ring of mammoth fossils
Pacific Northwest National Laboratory geologists have put out a call for teeth tusks, femurs and any and all other parts of extinct mammoths left by massive Ice Age floods in southeastern Washington.
22-Mar-2007 Sailing for science
When most people think of an ocean
cruise, they think of buffets and relaxing
in deck chairs. For Pacific Northwest
National Laboratory researcher Philip
Long, an expedition cruise aboard the
Joint Oceanography Institutes Deep
Earth Sampling (JOIDES) Resolution
research vessel meant 12-hour workdays
examining ocean floor core samples for
22-Mar-2007 Data-intensive computing key to predictive science
The ability to protect the nation
from terrorist attacks, discover the
hidden secrets of genes and monitor
and control the electrical power grid
requires the ability to process and
analyze massive amounts of data and
information in real time.
22-Mar-2007 An ounce of prevention
When you think about it, Americans go to great
lengths to be healthy these days. This generation is far
more knowledgeable about the benefits of a healthy
lifestyle than generations past. In addition to paying
attention to diet and exercise, many regularly take
precautions to avoid illness and disease. Today, taking
vitamin supplements, eating foods rich in antioxidants and
applying sunscreen are almost as commonplace
as brushing teeth in the morning. After all, an
ounce of prevention is worth a pound of cure.
22-Mar-2007 Carbon capture made easy
Gasification plants may be one
of the keys to a hydrogen economy,
if capture and sequestration of carbon
dioxide (CO2) becomes technically
and economically feasible. These plants
would transform fossil fuel feedstock,
including coal, biomass and municipal
wastes, into clean-burning hydrogen
gas where the only byproduct is water.
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.
1-Dec-2006 Nuclear energy and the 21st century
The world is entering a period of renewed interest and
growth in nuclear energy, driven by rising oil prices, growing
demand for electricity, new passively safe plant designs, and
low emissions of greenhouse gases, which some governments
need to meet Kyoto Protocol standards. The Kyoto Protocol
assigns mandatory targets for reducing greenhouse gas
emissions to signatory nations.
1-Dec-2006 Operations center is the real deal
Grid operators who spend their days
managing a piece of the nation's electric
grid could walk into the Electricity
Infrastructure Operations Center (EIOC)
at Pacific Northwest National Laboratory
and feel right at home.
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.
29-Nov-2006 Coal: An energy bridge to the future
For years, coal drove the transportation business in this country, and it may be poised for a comeback. A hundred years ago, steam engines burned tons of coal as they
pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel to fill our gas tanks and move cars and trucks.
20-Nov-2006 Fuel cell prototypes exceed expectations
Fuel prices continue to rise. However, one solution -- fuel cells -- is gaining on that problem. The Solid State Energy Conversion Alliance (SECA) has achieved the first of a threepart goal: developing solid oxide fuel cell systems that reduce fuel cell production costs by a factor of ten.
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.
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.
