Jefferson Lab hosts 100 of the brightest young minds in math and science
In a question-and-answer game format, the contestants were grilled on their knowledge in various fields of math and science. Morning sessions were in a round-robin format, followed by a double-elimination round in the afternoon. Winning first place earned Thomas Jefferson High School a trip to the Science Bowl Nationals to be held in Washington, D.C. in May. This was the team's third straight regional science bowl win; and it was last year's winner at Nationals.

Los Alamos' 60th anniversary
As it turns 60 years old, Los Alamos National Laboratory holds a special place in the modern-day genealogy of science and technology, says George "Pete" Nanos, the laboratory's interim director. "We are proud of our accomplishments. However, we will never rest on our laurels or be held motionless by the past."

Healing or self-damage: Immunoreceptors' 'split personality'
Sometimes described as a "liquid brain," the immune system is continually poised at the edge of disaster, required to aggressively attack invading pathogens without damaging its own body. The challenge of understanding the complexity of signaling entailed in such a delicately balanced system has been taken up by Los Alamos National Laboratory researchers, who are developing a mathematical model of immunoreceptors, a large and diverse group of proteins that decode regulatory signals.

Science at Los Alamos
Los Alamos is a laboratory with a mission. It began nearly sixty years ago with the Manhattan Project and the first successful nuclear test at Trinity Site. The Laboratory's mission has evolved through the years, and the Laboratory has evolved with it--but always in response to national needs and with a national security focus.

Simulation science: The key to understanding national infrastructures
The continuity of American life depends on reliable operation of a complex web of interdependent infrastructures. Disruptions in any one of these could jeopardize our society. A collaboration between Los Alamos and Sandia National Laboratories is helping policymakers understand how the nation's infrastructures work, are linked, and can be protected.

The next-generation supercomputer
In September 2003, the U.S. Department of Energy's Oak Ridge National Laboratory and Cray, Inc., of Seattle, Washington, will deploy Cray's X1 system at ORNL's Center for Computational Science. This next-generation supercomputer will be instrumental in addressing problems related to climate, biology, nanoscale materials, fusion, and astrophysics.

Shelf life guaranteed
The nation's nuclear weapons were originally designed to last for 20 to 25 years. Each year, the directors of the Department of Energy's three nuclear weapons labs must certify that the stockpile weapons will perform as designed. If the performance of an older weapon becomes questionable, lab scientists must decide how to replace its aging parts in order to restore its peak performance.
