By producing 24 milliamps of negative hydrogen ions at an energy of 2.5
MeV from a
unique radio-frequency quadrupole accelerator, Berkeley Lab scientists
and engineers are on track and on target to completing the SNS Front-End
System, the first major component of DOE's Spallation Neutron Source,
which will provide the most intense neutron beams ever generated for research.

A collaboration among environmental scientists at Berkeley Lab and Ontario's
Trent University provides a
new way to track the spread of toxic waste through the air, water,
and land in 24 regions of North America-- one of the first comprehensive
cross-border computer models of contaminant "transport and fate."

Biologists and computer scientists have joined forces to create a powerful
tool for comparing DNA sequences from two or three or even more organisms.
VISTA is a
fast way to spot sequence similarities -- or differences -- in everything
from short requlatory sequences to single genes to entire genomes. And it's
available on the web.
