eco-science
Stepping onto the site of a physics laboratory, you might expect to see enormous accelerators, ultra-powerful supercomputers, or scientists in lab coats racing between experiments. At one lab, however, what you will actually see are goats. At Lawrence Berkeley National Laboratory in Berkeley, California, goats roam through the hills, push over fences, and climb trees.

The search for extra dimensions
Although we now think of the universe as three bulky, nearly-flat dimensions, we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed.

Spallation Neutron Source amazing science facts
The New Year is bringing the science community a grand present: The Spallation Neutron Source at Oak Ridge National Laboratory. On schedule for completion in 2006, the Department of Energy's new science facility will provide researchers with the world's most powerful and most advanced tool for analyzing a host of materials with neutrons.

The sky's the limit
Earth's climate is noticeably changing over time. Glaciers are smaller, droughts last longer, and extreme weather events like fires, floods and hurricanes occur more frequently. PNNL researchers involved in the Atmospheric Radiation Measurement (ARM) Program are working to understand these phenomena through improved cloud representations in the computer models that simulate changes in the earth's climate.

Knowledge centers: Sweet suites of informational tools
Pacific Northwest National Laboratory has created a new way to manage scientific research and deal with the resulting information overload. Three types of knowledge centers -- science-based, technology-based and mission-based -- are tackling the daunting tasks of collecting, managing, visualizing, analyzing, distributing and storing massive data accumulations using unique software products.

Data-intensive computing to large science discoveries
The advancement in computing technology has enabled scientists to collect massive amounts of data, taking us a step closer to solving complex problems such as global climate change and uncovering the secrets hidden in genes. The exponential growth in the amount of data collected in research, however, has created an urgent technical challenge.

Innovative tools for high-performance computing
Solving complex scientific problems requires not only advanced high-performance supercomputers but also innovative software programs that can discover patterns and integrate data across different space and time scales. Researchers at PNNL are creating innovative software and processes to do just that.

Computational biology enabling new discoveries to solve complex global problems
Ask any experienced do-it-yourselfer or professional and they'll tell you the importance of using the "right tool for the right job." At Pacific Northwest National Laboratory's Computational and Information Sciences Directorate (CISD), the right tools are powerful high-speed computer systems that are analyzing vast amounts of data and enabling scientists to discover solutions to many complex global problems.

Cyber security
Do you worry about the security of your credit card when you buy something over the Internet? Or when you pay your bills electronically? What about business trade secrets communicated by email from engineering to manufacturing staff or sensitive data stored on local hard drives? Computer scientists at Pacific Northwest National Laboratory are using a systems approach combined with a multidisciplinary team of experts to address cyber security issues such as these.

NVAC: Visualizing a safer homeland
September 11, 2001 forever changed how Americans view national security. The responsibility for protecting citizens from future attacks has fallen on government shoulders in an increasingly discontented world. One way the Department of Homeland Security has responded is with new visual analytic technologies that transform volumes of documents, emails, images, videos and voice recordings into interactive visuals.

Environmental biomarkers provide early warning of disease
Outbreaks of Avian flu or "bird flu" during the past several years have disrupted the poultry industry. More ominous is that the virus spreads to humans. The ability to identify this disease early on may help prevent epidemics that wreak havoc on a country's economy and take lives. Now, researchers at Pacific Northwest National Laboratory, through the multi-year Environmental Biomarkers Initiative (EBI), are developing new techniques and tools for identifying these early warning signals also known as environmental biomarkers.

A limitless potential
Researchers believe carbon nanotubes may prove to be the most promising nanoscale materials for multifunctional applications. These hollow tubes of carbon often have multiple, concentric layers of carbon sheets, like rings of a tree. A single-wall carbon nanotube (SWNT)--one sheet of carbon atoms rolled into a tube--has special properties resulting from a structure much more like that of a one-dimensional molecule than bulk graphite.

Meet the grid
Today's cutting-edge scientific projects are larger, more complex, and more expensive than ever. Grid computing provides the resources that allow researchers to share knowledge, data, and computer processing power across boundaries.

A new attraction
Jian Shen, a recipient of the Presidential Early Career Award in Science and Technology in 2004, is a research theme leader at the Department of Energy's Center for Nanophase Materials Sciences. Many predict that Shen's novel techniques for growing and studying magnetic nanostructures will attract a growing number of guest scientists to ORNL's new nanocenter.

Biological tubes to serve as miniature drug capsules
By mixing two common cell ingredients, scientists have assembled tiny hollow tubes whose ends can be open or closed, giving them great potential to serve as drug capsules thousands of times thinner than a human hair, but still 10 times wider than a gene.

Virginia Tech wins architecture, dwelling contests at Solar Decathlon
Virginia Tech has taken an early lead in the Solar Decathlon, now underway on the National Mall in Washington, D.C., by winning Architecture and Dwelling, the first two of 10 contests in the competition.

Asymmetric insight
Like climbers assessing a new route before making the ascent, physicists have been looking for footholds on a vertiginous new terrain. These footholds contain important information for trekking to TeV heights (the lofty trillion electron volts energy scales of future colliders).

Super-fast super-sensitive detectors
Only detectors with the greatest precision capabilities will measure up to the machine seeking to explore supersymmetry, dark matter, the Higgs mechanism, and new physics that hasn't yet been imagined. Their shapes and configurations might be familiar, but their inner workings�the materials and electronics charged with creating views of new physics�will carry a symbolic branding: "Product of the 21st century."

Practical climate financing � Using markets to drive cleaner energy production
Every day, people in China get sick just from breathing the air. Many die prematurely. In economic terms, pollution costs China eight to ten percent of gross domestic product in lost productivity, according to World Bank estimates. Air pollution accounts for three-quarters of that productivity loss.

Clouds help clear up global warming questions
Is Earth's climate really changing? Climate researchers have answered this question with a resounding "Yes!" It is widely accepted that Earth's temperature will rise two to three degrees Celsius over the next 50 years if current fossil fuel emissions continue to grow at their present rate. The next question is how this warming trend will affect the climate--particularly water resources.
