An interview with the director
Dr. Leonard Peters joined Pacific Northwest National Laboratory as director on April 1, 2003. Outgoing and affable, Peters insists that new acquaintances refer to him simply as "Len." His leadership style is similarly direct and free of pretense. We recently visited with Len to see how he is settling into his new role and to gain a better understanding of his vision for PNNL.

Twenty years at the energy frontier
The Tevatron began operations in late 1983 when the E715 experiment initiated the use of the world's highest-energy beams. Since then more than forty fixed-target experiments have used Tevatron beams of protons, pions, muons, photons, hyperons and neutrinos to expand our knowledge of particles and forces.

Supernovae shape up for cosmology
A collaboration among the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the European Southern Observatory, and the University of Texas has yielded the discovery that Type 1a supernovae do not explode spherically. This discovery marks the first time that the intrinsic polarization of a normal Type 1a supernova has been detected.

Scientists develop recyclable catalyst for solvent-free reactions
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have developed a catalyst that can be recycled with no waste-eliminating the need for solvents used in synthesis of organic compounds such as agricultural products and pharmaceutical agents. The catalyst--beneficial for reducing waste and manufacturing costs--is described in the July 31, 2003, issue of Nature.

Startup of MINOS
Scientists of the MINOS collaboration announced the official start of data-taking with the 6,000-ton detector for the Main Injector Neutrino Oscillation Search on Thursday, August 14. Physicists will use the MINOS detector, located deep in an historic iron mine in northern Minnesota, to explore the phenomenon of neutrino mass.

Plant fertility research benefits from discovery of molecular signaling system
University of Chicago researchers have discovered that gamma-amino butyric acid plays a crucial role in plant reproduction. This research is important to the agriculture industry--which provides 80 percent of the world's food supply--and has broad implications for cell-to-cell interactions and signaling in plant and animal systems. The research, supported in part by the U.S. Department of Energy, is reported in the July 11, 2003, issue of Cell.

Microfluidic device rapidly captures and releases proteins
Researchers at the U.S. Department of Energy's Sandia National Laboratory have developed a microdevice that can easily collect and release proteins in aqueous solution in under a second. The small, portable prototype device shows promise in the biotechnology arena, with capabilities targeted at near-instantaneous analysis of suspect proteins and compatibility with hand-held sensors. This microfluidic device is discussed in the July 18, 2003, issue of Science.

Pentaquark: New evidence of an exotic five-quark particle
Results of an international research collaboration have yielded convincing evidence of a subatomic particle consisting of five quarks. The results of the research--conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility--were announced at the Conference on the Intersections of Particle and Nuclear Physics in May 2003.

Cadmium quickly causes calcium loss in bones
Researchers at the U.S. Department of Energy's Argonne National Laboratory have demonstrated that cadmium--found in some industrial workplaces and in cigarette smoke--releases calcium from bone within hours of exposure. Knowing how this toxic metal interacts with bone may lead to the screening necessary to detect the early or pre-stages of excess bone loss--before much damage occurs.

Sea salt study provides better understanding of climate modeling
A recent study by researchers from the U.S. Department of Energy's Pacific Northwest National Laboratory and the University of California, Irvine, has provided a new understanding of sea salt's role in atmospheric chemistry. This study--focusing on sulfur dioxide and its conversion to sulfuric acid in air--will allow scientists to more accurately predict and capture information in models related to regional or global warming. Results of the study are reported in the July 3, 2003, issue of Science Express.

From Georgia with innovation: A profile of Jefferson Lab staff scientist Youri Sharabian
By the time he was in 7th grade, Sharabian had built a small workshop in his family's basement. When his father came home from work with a design for small engine springs, but complained of the difficulties in making them quickly, Sharabian was intrigued and subsequently fashioned a specialized apparatus capable of winding wire accurately and rapidly. His father was so impressed that the innovation was adopted with minor modifications directly onto the factory floor.
