RIKEN-BNL Research Center dedicates new supercomputer for physics research
DOE/Brookhaven National LaboratoryBusiness Announcement
A new computer – the RIKEN BNL Research Center supercomputer – was unveiled today at a dedication ceremony at the U.S. Department of Energy's Brookhaven National Laboratory attended by physicists from around the world. It is called QCDOC for quantum chromodynamics on a chip, and it was designed and built by Brookhaven Lab, Columbia University, IBM, RIKEN -- The Institute of Physical and Chemical Research in Japan, and the University of Edinburgh.

Two studies offer clues about how alcoholic behavior is 'switched' on
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
As part of an ongoing effort to understand the biochemical basis of alcohol abuse, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have published two studies on how modulating receptors for dopamine -- a chemical "signaler" in the brain's reward circuits -- affects drinking behavior in mice and rats.

Moving electrons at molecular, nanometer scales
DOE/Brookhaven National Laboratory
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.

RHIC scientists serve up 'perfect' liquid
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
Simultaneous peer-reviewed publications by the four detector groups conducting research at the Relativistic Heavy Ion Collider (RHIC) say the giant atom "smasher" has created a new state of hot, dense matter out of quarks and gluons. But unlike the gas of free quarks and gluons that was expected, the matter created in RHIC's heavy ion collisions appears to be more like a liquid.

In 'ocean floor' lab at Brookhaven scientists create, study methane hydrates
DOE/Brookhaven National Laboratory
Scientists at BNL have recreated
the high-pressure, lowtemperature
conditions of the
sea floor in a tabletop apparatus
for the study of methanehydrates,
an abundant but currently
out-of-reach source of
natural gas trapped within sediments
below the ocean floor.

Poplar trees redirect resources in response to simulated attack
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
Scientists at the US Department of Energy's Brookhaven National Laboratory have applied some of the same techniques used in medical imaging to track the distribution of nutrients in poplar trees in response to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big help in unraveling plant biochemistry.

Quasiparticle behavior in bose quantum liquids
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
Quasiparticles carry energy in condensed matter. In the world of quasiparticle physics, understanding when and how these energy carriers fail opens doors to another level of understanding, and can lead to many new and important theories. Scientists at Brookhaven National Laboratory have discovered the failure point for the quasiparticle construct, the standard model of condensed matter physics, which could have far-reaching implications in the study of high-temperature superconductors.

Spintronic materials show their first move
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
How much energy does it take for an electron to hop from atom to atom, and how do the magnetic properties of the material influence the rate or ease of hopping? Answers to those questions could help explain why some materials become conductors only in a magnetic field and help scientists learn how to use the electron's "spin" to carry information in a new field known as spintronics.

Increasing charge mobility in single molecular organic crystals
DOE/Brookhaven National LaboratoryPeer-Reviewed Publication
Flexible displays that can be folded up in your pocket? More accurate biological and chemical sensors? Biocompatible electronics? In research that may help determine the best materials for a wide range of future electronics applications, a scientist from the U.S. Department of Energy's Brookhaven National Laboratory will report on the intrinsic electronic properties of molecular organic crystals at the March 2005 meeting of the American Physical Society.
