Livermore supercomputers boost scientific progress
Scientists at Lawrence Livermore National Laboratory and elsewhere increasingly are turning to sophisticated, three-dimensional supercomputer simulations to suggest and verify their theories and to design, complement and sometimes replace experiments.

Do black holes exist? Or are they really 'dark energy stars'?
Lawrence Livermore National Laboratory physicist George Chapline says that black holes do not really exist. Instead, he proposes that the mass of compact astrophysical objects consists of the same dark energy that makes up 60 percent of the mass of the universe.

PPPL-led team completes work on JET alpha detector
Studying the behavior of alpha particles produced in fusion plasmas is of paramount importance for ITER and other advanced fusion devices in which these particles are expected to be the predominant source of plasma heating. An international team led by PPPL physicist Doug Darrow recently completed work at PPPL on the construction of diagnostic equipment that will be used to measure alpha particles and other energetic particles ejected from the plasma in the Joint European Torus (JET) in Culham, England.

Small is big for PPPL's Paul Trap
The Paul Trap Experiment at the Princeton Plasma Physics Laboratory is trying to determine the properties of intense charge particle beams as they travel through transport systems. But PTSX, measuring only three meters in length -- much shorter than a typical particle accelerator -- uses some interesting physics to simulate the conditions in an accelerator.

MRI experiment operational at PPPL
The formation process of stars and planets remains one of the big questions in astrophysical science. Currently, scientists do not understand the required conditions and the accretion, or matter collection process, involved in star and planet formation. But the Magnetorotaional Instability (MRI) experiment now operational at the Princeton Plasma Physics Laboratory may shed light on this mystery.

Moving electrons at molecular, nanometer scales
Learning how to control the movement of electrons on the molecular and nanometer scales could help scientists devise small-scale circuits for many applications, including more efficient ways of storing and using solar energy.

Ultra-fast science succeeds at SLAC
The Sub-Picosecond Pulse Source (SPPS) collaboration has published data from the first experiments ever using a linear accelerator-based femtosecond x-ray source, and has developed an important tool for ultra-fast science. SPPS makes the world's shortest bunches of electrons in the SLAC linear accelerator and turns them into very bright pulses of x-ray light one thousand times shorter than those made in synchrotron rings like SPEAR3.

Sandia Labs undergoes management changes
The Sandia Corporation Board of Directors has named Dr. Thomas O. Hunter President of Sandia Corporation and Director of Sandia National Laboratories, effective April 29. Hunter most recently has served as Sandia's senior vice president for Defense Programs, with oversight of the labs nuclear weapons programs.

Partnering paves way for science solutions
The word partnership conjures up the image of a couple--a couple of people, a couple of businesses, a couple of governments--coming together to work on a relationship, business venture or project. Many partnerships are still based on two. But that premise is rapidly changing--especially in science.

Corporate care for the community
Managing a national laboratory extends beyond serving the scientific and technical needs of clients. It also means serving the needs of the local community. Since 1965, Battelle, which operates Pacific Northwest National Laboratory for the U.S. Department of Energy, has contributed more than $13 million in charitable contributions to the communities in which PNNL staff live--Richland, Kennewick, Pasco, Seattle and Sequim, Wash.

Director of global design effort announced at international linear collider workshop
The 2005 International Linear Collider Workshop kicked off March 18 by announcing the director for the newly formed Global Design Effort (GDE) for the proposed electron-positron collider.

Greater security with EM coil
An electromagnetic coil system developed at Pacific Northwest National Laboratory adds truth serum to treaty verification by narrowing the uncertainty for what's inside a sealed container.

Seismic detectives go underground
Researchers at Pacific Northwest National Laboratory are using data gathered by seismology stations to develop a mathematical framework for identifying and locating seismological events around the world. Their work, part of the National Nuclear Security Administration's Ground Based Nuclear Explosion Monitoring Research and Engineering Program, will be used by the U.S. government to monitor explosions and weapons tests.

PNNL scientist just keeps on giving
Aaron Diaz, a staff scientist at Pacific Northwest National Laboratory, is the first PNNL staff member to win a Hispanic Engineer National Achievement Award. Diaz also is awarded the Christopher Columbus Fellowship Foundation's Homeland Security Award.

Recycling a legacy of the Cold War
The tons of surplus plutonium stockpiled in the United States and the former Soviet Union are no longer of interest to anyone...except perhaps terrorists. This realization led to an agreement between the United States and the Russian Federation to dispose of 35 metric tons of plutonium each by removing the plutonium "pits" from the nuclear weapons and turning them into nuclear power plant fuel.

Peace of Mind
Following the breakup of the Soviet Union, many Russian weapons scientists frequently found themselves with little work, no pay for the work they were doing and crumbling facilities. Russian and U.S. government officials were concerned that former weapons scientists may be tempted to go to work for countries with active nuclear programs, so they worked together to come up with a way to reduce that incentive.

Education - a key to advancing nonproliferation
Cultivating minds in science and technology has always been a focus at Pacific Northwest National Laboratory, but an international need for nonproliferation experts is now a driving force to create new nonproliferation education programs and expand the breadth and depth of existing ones.

X-ray blaze on an invisible world
The way that a horse trots intrigued Leland Stanford. After a term as California's governor and with a fortune assembled from building the US transcontinental railway, Stanford lived the life of a country gentleman near his Palo Alto Stock Farm.

Science from a hole in the ground
When Alice famously went down the rabbit hole, she ended up in Wonderland. Now, a group of US scientists from fields as diverse as microbiology and particle physics, rock mechanics and molecular evolution are proposing to go down their own version of the rabbit hole into the scientific wonderland of a Deep Underground Science and Engineering Laboratory.
