With a scanning tunneling miscroscope (STM), researchers based at Lawrence Berkeley National Laboratory and the University of California at Berkeley have imaged a unique eight-fold configuration of quasiparticle interference in the high-transition-temperature superconductor Bi-2212 (BSCCO). Because the electronic patterns change as the STM's bias voltage changes, the discovery calls into question the hypothesis that high-Tc superconductivity necessarily coexists with the peculiar electronic state known as the "stripe phase."

A Lawrence Livermore National Laboratory astrophysicist, working with an international group of researchers, has discovered that high-energy neutrinos -- particles that rarely interact with other matter -- are produced in the accretion discs of neutron stars in amounts significant enough to be detected by the next-generation of neutrino telescopes.

Scientists at Lawrence Berkeley National Laboratory and DOE's Joint Genome Institute have devised a new way to compare the genomes of humans and other closely related primates. Called "phylogenetic shadowing," the technqie holds promise for studying genes implicated in diseases specific to these species.

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have created the first three-dimensional global map of the protein structure universe. This map provides important insight into the evolution and demographics of protein structures and may help scientists identify the functions of newly discovered proteins.

The Federal Laboratory Consortium for Technology Transfer has granted the Extreme Ultraviolet Lithography (EUVL) project an Excellency in Technology Transfer award for technology that will lead to microprocessors that are tens of times faster than today's most powerful chips. The technology also will create memory chips with similar increases in storage capacity.

SLAC is part of an international team recently awarded a certified data transfer speed record by the Internet2 consortium. The team transferred un-compressed data at 923 megabits per second for 58 seconds from Sunnyvale to Amsterdam. More than 3500 times as fast as a typical home Internet broadband connection, these new technologies augment new applications such as digital libraries, virtual laboratories and distance learning.

Researchers at the Nearby Supernova Factory, based at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, have discovered 34 supernovae during the system's first year of operation. This discovery was announced at the 201st meeting of the American Astronomical Society in January 2003.

Physicist Fred Kavli and the Kavli Foundation pledged $7.5 million to establish the Kavli Institute for Particle Astrophysics and Cosmology. The Institute will foster collaboration between faculty from Stanford's Physics and Applied Physics departments and SLAC, operated by Stanford for the DOE. The 25,000 square-foot building on the SLAC site will be completed in 2005.

Lawrence Livermore National Laboratory astronomers are major partners in a scientific collaboration that will conduct an extremely novel search for small, comet-like bodies in the outer solar system using four half-meter telescopes. The work was described today at the winter meeting of the American Astronomical Society.

Researchers at the Lawrence Livermore National Laboratory have discovered another fingerprint of human effects on global climate. Recent research has shown that increases in the height of the tropopause over the past two decades are directly linked to ozone depletion and increased greenhouse gases.
