Simulating turbulence in magnetic fusion plasmas

DOE/Lawrence Livermore National Laboratory

Powerful three-dimensional simulations are helping researchers to speed the development of magnetic fusion energy.

LLNL scientists to present global warming mitigation tool for ridding the atmosphere of excess carbon

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Researchers from the Lawrence Livermore National Laboratory today will present evidence that a new method for capturing carbon dioxide from power plants and placing it in the ocean has less impact on marine life than atmospheric carbon dioxide release or other global warming mitigation methods, such as direct injection and ocean fertilization.

Astronomers unveil first detection of dark matter object in the Milky Way

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Astronomers from the Lawrence Livermore National Laboratory, in collaboration with an international team of researchers, have directly detected and measured the properties of a gravitational microlensing event in the Milky Way.

Homeland security

DOE/Lawrence Berkeley National Laboratory

Lawrence Berkeley National Laboratory recently took information on three projects to DOE headquarters in Washington to brief Secretary of Energy Spencer Abraham and Director of Homeland Security Tom Ridge. They were part of an exhibition of more than two dozen counter-terrorism technologies sponsored by the DOE.

Researchers discover that volcanic eruptions masked global warming during the past 20 years

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Researchers at Lawrence Livermore National Laboratory, who examined temperature data from 1979 to 1999, have discovered that large volcanic eruptions cooled the lower troposphere (the layer of atmosphere from the Earth’s surface to roughly 8 km above it) more than the surface, and likely masked the actual warming of the troposphere.

New way to make 'neuts'

DOE/Lawrence Berkeley National Laboratory

Neutrons can penetrate deeply to find defects in large machine parts or tiny microdevices, elucidate the structure of biological systems and polymers, sense fluids in geological formations, and probe solids and liquids on the atomic scale.

A new way to visualize cells and nuclei

DOE/Lawrence Berkeley National Laboratory

To learn how tissues develop and maintain their organization—and especially to learn what goes wrong when cancer strikes—it's essential to study individual cells and their nuclei within tissues. The problem is that in real tissues, and in many cell cultures grown in the laboratory, cells are often tightly clustered; their boundaries and the borders of their nuclei are hard to distinguish.

National Lab astrophysicists explore supernovae with an eye on national security

DOE/Lawrence Livermore National Laboratory

The SciDAC program within DOE's Office of Advanced Scientific Computing Research supports High Energy and Nuclear Physics research in the use of terascale computers to dramatically extend exploration of the fundamental processes of nature, as well as advance the ability to predict the behavior of a broad range of complex natural and engineered systems.

Lab scientists develop DNA signatures for salmonella strain that are expected to drastically speed detection

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Salmonella may soon be identified within hours, rather than as long as a couple weeks, thanks to a rapid-detection technique developed by Lawrence Livermore National Laboratory researchers. A paper by biomedical scientists Peter Agron and Gary Andersen about their development of a DNA-based detection system will appear in Thursday’s edition of the journal "Applied & Environmental Microbiology."

Gene-rich pufferfish DNA decoded

DOE/Lawrence Berkeley National Laboratory

Although the Fugu genome contains essentially the same genes and regulatory sequences as the human genome, it carries those genes and regulatory sequences in approximately 365 million bases as compared to the 3 billion bases that make up human DNA. With far less so-called "junk DNA" to sort through, finding genes and controlling sequences in the Fugu genome should be a much easier task.
