Understanding the mysteries of high-temperature superconductors
High-temperature superconductors (HTSCs) operate in mysterious ways, but scientists are starting to understand their peculiarities by using a state-of-the-art spectroscopy system at SSRL.

Gamma-ray bursts shower the universe with metals
According to the results from a Livermore computer model, some of the small change jingling in your pocket contains zinc and copper created in massive gamma-ray bursts (GRBs) that rank as the most impressive light shows in the universe.

Enhanced national security through international research collaborations
National security today requires broad and effective engagement in the international arena.

Shaping future
In its next-generation aircraft carrier, the Navy, with assistance from Sandia, is seeking to reduce manpower by 10 to 30 percent, but not by heaping more work on individual sailors. The goal is to use increased technology and improvements to carrier air wing flight operations, maintenance, and support functions to reduce the overall workload per sailor.

Improving automative coating
"Clearcoats" applied over layers of automotive paint not only enhance automobile appearance, but also serve as a first line of defense against attack from moisture, acid rain, and ultraviolet radiation.

SPEAR3 'breathes' in response to temperature changes
As the sun rises each day, warming the grounds and buildings of SLAC, the entire SPEAR3 facility expands in response. The change is minuscule, on the scale of a few microns--far too slight to observe with the naked eye.

More power to the GRID
On August 16, 2004, a year and two days after the largest power blackout in U.S. history, 3M announced the first commercial sale of an advanced conductor for overhead power lines.

Industrial efficiency
Improving the efficiency of manufacturing processes is an important component of ORNL's energy mission. Over the years Oak Ridge materials researchers have pursued this goal for a variety of industries through the Department of Energy's Industrial Technologies Program (ITP).

Letting the sunshine in
The outlook is sunny for the Laboratory's prospects of commercializing hybrid solar lighting (HSL). The ORNL technology uses sunlight to reduce the need for indoor electric lighting, the largest consumer of electricity in commercial buildings.

Pushing the envelope
If ORNL's Jeff Christian could have his way, next-generation houses in East Tennessee would generate as much electricity as they consume.

4-Mar-2005
Closer to the customer
Without warning, the August 14, 2003, power blackout removed electricity for millions of people in the United States and Canada. The next day manufacturers still had no power, contributing to an estimated cost to the U.S. economy of $6 billion.

Multiple roads to the hydrogen car
In his 2003 State of the Union address, President George Bush communicated an ambitious vision that the United States will lead the world in developing clean, hydrogen-powered automobiles.

Aid for the auto industry
Since the 1970s the U.S. government has supported research and development designed to help Americans use energy more efficiently. Because a large portion of American oil imports is used for transportation, the Department of Energy makes substantial investments at ORNL in several technologies designed both to improve fuel efficiency and reduce carbon emissions into the atmosphere.

Energy prophets: US oil dependence
U.S. oil imports are at an all-time high, accounting for approximately 57% of domestic consumption. Americans today import some 12 million barrels per day at a cost that in 2004 skyrocketed above $50 a barrel.

Providing international solutions
As U.S. researchers focus on domestic energy issues, they could easily miss the century's dominant energy challenge: to increase energy supplies for the world's growing population without contributing further to environmental degradation. Accomplishing this monumental task would represent the most fundamental change in the world's energy production since the Industrial Revolution.

Energy efficiency: Stretching America's resources
The United States and the world face enormous energy challenges. Petroleum prices are at record highs with no end in sight. The emergence of China and India as major contributors to global demand brings new urgency to political and economic concerns about oil dependence.

New, nondestructive soil-analysis device measures carbon, more, in situ
With funding assistance from DOE's Office of Science and the National Energy Technology Laboratory, Lucian Wielopolski of the Environmental Sciences Department (ES) has developed a device that can measure carbon and other elements in soils non-destructively and in situ.

Cosmic tune-up: Cosmic rays help prime BABAR systems
Cosmic rays harmlessly stream through everything on Earth--our bodies, the scintillator counters in the Visitor's Center and the BaBar detectors.

Catching the cracks
Catching cracks in nuclear nozzles is no easy task when they are caused by normal stresses and corrosion inside a nuclear reactor. Approximately 70 nozzles per reactor allow control rod drive shafts to pass through the top of a reactor pressure vessel head so that the power level of the reactor can be controlled.

NuSTAR satellite approved for further study by NASA
The Nuclear Spectroscopic Telescope Array (NuSTAR) satellite may soon give astrophysicists a new window on the universe. Designed to image high-energy X-ray radiation, it will capture sharp images of black holes, supernovae, and galactic nuclei. And if NASA gives the project final flight approval early next year, it could be in orbit by the end of the decade.

Pacific Northwest lab forms Institute for Interfacial Catalysis, names director
Pacific Northwest National Laboratory today launched an $8 million Institute for Interfacial Catalysis to explore the fundamental chemical changes on surfaces where catalytic reactions take place. The Department of Energy lab also announced the appointment of University of Texas at Austin chemist John M. "Mike" White as the institute's director.

Mining geothermal resources
It's beautiful on beaches and receives kudos for its use in paint, tires, paper, toothpaste, and even in kitty litter--but it's a real pain in geothermal power plants.

Experiment and theory have a partner: Simulation
Even before Lawrence Livermore opened in September 1952, cofounders E. O. Lawrence and Edward Teller recognized the need for a computer and placed an order for one of the first production Univacs.

'Quantum Diaries' reveal the secret lives of modern physicists
What is it like to be a physicist 100 years after Einstein pushed physics to a new frontier? A new website featuring researchers at Stanford and around the globe is helping answer that question by cataloging the daily lives of more than 25 physicists. Quantum Diaries celebrates the World Year of Physics by recording the experiences, thoughts, impressions, triumphs and disappointments of these men and women in their blogs, or web-based logs.
