DOE Joint Human Genome Effort Exceeds Sequencing Goal

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

The U.S. Department of Energy today announced that its Joint Genome Institute surpassed its ambitious goal of sequencing 20 million base pairs for fiscal year 1998. The Institute ranks third worldwide in terms of its total contribution of human DNA sequence to public databases.

Semiconductor Nanocrystals: The Next Thing In Fluorescent Probes

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Some of the more shadowy secrets of biology may soon be illuminated through the use of a new type of fluorescent probe developed by Lawrence Berkeley National Laboratory and the University of California at Berkeley scientists. The new probes offer a distinct advantage over conventional dye molecules in that they emit multiple colors of light, which means they can be used to label and measure several biological markers simultaneously.

Powerful Computers Advance Fusion Research

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory report a major advance in the computer modeling of fusion plasmas in the September 18 edition of Science magazine. The new results were obtained utilizing the Massively Parallel Processing capabilities of the DOE's National Energy Research Scientific Computing Center (NERSC) at the Lawrence Berkeley National Laboratory in Berkeley, California.

New Technique Reveals Identity Of Near-Neighbor Atoms

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

In a development that holds much promise for future studies of surfaces and interfaces in solid materials, including magnetic, environmental, and biological systems, researchers at Lawrence Berkeley National Laboratory have successfully tested a method that not only directly determines the identity of a specific atom in a sample, but also directly determines the identities of its neighbors.

Inexpensive Photochromic Material May Help Next Generation Of Energy-Efficient Windows

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Scientists at Lawrence Berkeley National Laboratory and the University of California, Berkeley have discovered an inexpensive material that changes color on exposure to light. The material may help the effort to develop a next generation of energy-efficient windows that switch from transparent to opaque spontaneously.

Sealing Heating And Ventilation Ducts: Use Anything But Duct Tape

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

You can use duct tape for many tasks but it shouldn't be used to seal heating and air conditioning ventilation ducts. Though commonly used for that purpose, tests show that it reliably fails to do the job. That's the findings of energy efficiency researchers at Lawrence Berkeley National Laboratory.

Milestone In Mitochondrial Structure Revealed

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

An international team of researchers which includes scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory has determined the complete crystal structure of one of the four protein complexes in the mitochondrial respiratory chain. Called cytochrome bc1 or complex III, this enzyme plays a critical role in the relay of electrons for producing energy that sustains the health of tissues, organs, and the body as a whole.

Carbon-36 Fullerenes Could Be Higher-Temperature Superconductor

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Theorists at Lawrence Berkeley National Laboratory, whose calculations motivated the successful synthesis of materials based on carbon-36 fullerenes, have calculated that these systems may lose all electrical resistance at temperatures far higher than any other carbon structure -- perhaps even at temperatures in the range that superconducting copper-oxide ceramics have achieved.

Did The Big Bang Come With Strings Attached?

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

The power of supercomputers at the National Energy Research Scientific Computing Center (NERSC) has enabled Julian Borrill of the Department of Energy's Lawrence Berkeley National Laboratory to model, in striking detail, a possible state of the universe only a hundred billionth of a trillionth of a trillionth of a second (10-35 second) after the Big Bang.
