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.

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.

11-Feb-2005
LCLS collaboration revs up
The Linac Coherent Light Source (LCLS) collaboration met in January to focus on beginning to build the world's first X-ray free electron laser.

'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.

Beyond the standard model
At almost any particle physics conference, meeting, or lunch table, the phrase "physics beyond the Standard Model" is heard over and over again. What's wrong with the Standard Model, anyway? Why are physicists so sure that there is something beyond it? And why do they think they can find it anytime soon?

Let it rain
Toward the end of a ten-year experiment in 1991, postdoc Hungye Dai of the University of Utah was puzzling over some really unusual data. The experiment was Fly's Eye, which pioneered a new method of studying ultra-high-energy cosmic rays by monitoring the faint flashes of ultraviolet light produced in the sky when the particles hit the upper atmosphere.

Sold on cold
One hot day in August, particle physicists turned cold. That's the day the International Technology Recommendation Panel (ITRP) announced the decision to pursue "cold" superconducting technology for what physicists hope will be the world's next big particle accelerator, the International Linear Collider. Going cold, instead of recommending a "warm" option that had also been under development, has far-reaching consequences for laboratories, scientists, industries and governments across the globe. What does "cold" mean, and why did particle physics choose superconducting technology?

Extreme neutrinos
Kurt Woschnagg has been waiting nine days to catch a plane to the South Pole. He flew for 15 hours from San Francisco to New Zealand, waited several days to spend another eight hours in a cargo plane to McMurdo Station in Antarctica, only to wait again for the weather to clear.

The growth of inflation
It was a true Eureka moment if there ever was one. On the night of December 6, 1979, an obscure Stanford Linear Accelerator Center postdoc was up late, sweating over an even more obscure problem about particles called magnetic monopoles. Looking at his calculations the next day, the usually low-key Alan Guth annotated the words "Spectacular Realization" at the top of the page. Guth had discovered cosmic inflation, an idea which some have later called the most important in cosmology since the big bang.

Nothing is simple for the Center for Global Security
As the saying goes, nothing is ever simple--especially when it involves Pacific Northwest National Laboratory's Center for Global Security. Even achieving some progress in solving global security problems often requires a complex and many-pronged effort.

Innovative glass fibers shine in radiation detection
Being flexible in the rigid world of glass radiation detectors has made Pacific Northwest National Laboratory's glass fiber optic detectors very popular.

First GLAST tracker arrives at SLAC
The Gamma Ray Large Area Telescope (GLAST) satellite project celebrated a milestone last month with the arrival of the first tracker module at SLAC.
