MSL's fungal work leads to new research directions
Some people view fungi as mere mold-- a nuisance. Many, however, see great potential in these unique organisms. PNNL's Marine Sciences Laboratory in Sequim, Wash., possesses a rich history of fungi-related research and a collection of more than 200 strains of fungal species, some of which have been developed to perform environmental remediation and other tasks.

It's not raining cats anymore
The mystery of why panthers were dropping dead from the trees in the Florida Everglades was solved fairly quickly. The mystery of how they were being poisoned with mercury took a little longer. Scientists from PNNL's Marine Sciences Laboratory were part of a team of researchers involved with the initial assessment of mercury contamination in the Florida Everglades project between 1993 and 2000.

Culvert technology may help young salmon muscle their way upstream
Tens of thousands of culverts lie beneath roads in the Pacific Northwest, successfully moving water under the roadbed to preserve pavement and prevent flooding. At the same time, many are blocking juvenile salmon from migrating upstream to the habitat they need to survive and grow.

Jaws IV: Algae takes on CO2
Billions of tons of carbon dioxide from fossil-fuel-fired power plants are pumped into the air each day, contributing to global warming. Scientists at PNNL's Marine Sciences Laboratory in Sequim, Wash., are looking at marine algae as a solution to global warming caused by carbon dioxide emissions from fossil-fuel-fired power plants.

Photosynthesis shines as remediation tool
Marine construction, wood treatment, agricultural chemical production, chlorine production-- for decades we have been dumping waste into our harbors, many of which are now considered some of the most contaminated hazardous waste sites in the United States. Battelle researchers at PNNL's Marine Sciences Laboratory have developed a promising technique for remediating contaminated sediments in seawater and freshwater ecosystems.

Short-term estrogen exposure cuts fish fertility
A new study by Pacific Northwest National Laboratory and the University of Idaho shows that exposure to estrogen affects adult fish as they swim through rivers, lakes and streams to spawn. The study suggests that when adult male fish are exposed to short-term and low concentrations of synthetic estrogen, their fertility can drop by as much as 50 percent.

Marine Sciences Laboratory -a prized resource- expands capabilities
Renewed interest in homeland security, continued need for environmental solutions and a growing market for industrial products have made Pacific Northwest National Laboratory's Marine Sciences Laboratory (MSL) in Sequim, Wash., a focal point for developing new capabilities. Nestled in the quiet harbor of Sequim Bay on the Olympic Peninsula, MSL was established in 1967 and features state-of-the-art facilities. Over the years, MSL staff have conducted advanced research aimed at preserving and protecting the coastal and marine environment.

Proteomics research at home at PNNL
Proteomics, the study of proteins in living organisms, is one of the next major frontiers for the scientific community--and Pacific Northwest National Laboratory will play a significant role in unlocking the mysteries of proteins. Through its newly established Prototype Sample Processing and Proteomics Facility, PNNL will help pave the way to eliminating diseases such as muscular dystrophy and for creating targeted drugs.

New product offers alternative to toxic deicers
With the U.S. military using nearly 3 million gallons of toxic glycol-based deicer a year in addition to the nearly 30 million gallons of aircraft deicing fluid commercial airlines use, the U.S. Department of Defense looked to Battelle for a more environmentally friendly solution to deice aircraft. Working together, Battelle researchers at PNNL and Columbus, Ohio, developed a safe, biodegradable, nonglycol based product--Degradable by Design Deicer^TM or D³.

Regional program touts cooperation for economic growth
Pacific Northwest National Laboratory's Office of Northwest Regional Programs (ONRP) is emphasizing cooperation as a way to energize economic development efforts in Washington, Oregon and Idaho.

Tiny technology offers potent solution for military, industry
Researchers, with funding from the Defense Advanced Research Projects Agency, have developed a potentially high-energy microscale power system that can be used as an alternative to conventional batteries for microelectronic devices crucial to America's military troops.

No more free ride for phytoplankton
They may not be terrorists, but they can be sneaky--phytoplankton. These single-celled algae can sneak into nonindigenous harbors and coastal waters via ships' ballast water. Toxins from the phytoplankton can be taken up by shellfish and become harmful to humans who consume the shellfish.

MINOS: Last plane at Soudan
After four years of work in a former iron mine a half-mile underground, the Main Injector Neutrino Oscillation Search collaboration celebrated a milestone for the ambitious MINOS particle physics experiment. On June 5, technicians erected the last of 485 house-high detector planes of steel and plastic in the Soudan Underground Laboratory in Soudan, Minnesota.

Why accelerators matter
Accelerators are also crucial to realizing the opportunities to dramatically advance our understanding of the universe and the laws that govern it. Not only can accelerators reveal much about the fundamental particles and forces, but also they can make discoveries that are critical to understanding the cosmos.

RunII status and prospects
In mid-August, just a few weeks from now, CDF and DZero experimenters will present the first full round of Run II physics results at the Lepton-Photon Symposium at Fermilab.

Research offers clues to plaques in Alzheimer's disease
Researchers at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have made a breakthrough in the study of Alzheimer's disease: discovery of the strategic sites where amino acids can be removed from self-assembling, insoluble peptides that form fibrils in the brains of patients with the disease. With this discovery, researchers can now study the self-assembly process of the entire peptide.

At Los Alamos: Guarding the air we breathe
It's a sunny morning in late June. Tourists and locals throng midtown Manhattan, near Central Park South. The air carries a mix of aromas--sweet scents from blossoming trees in Central Park, a potpourri of ethnic foods from nearby restaurants, the pungent blend of sauerkraut and roasting hot dogs from a street vendor. But unscented and unnoted by the crowds, the air is also laced with anthrax spores from a bioterrorist attack.
