THE STRANGE CASE OF THE DISAPPEARING QUASIPARTICLES, March 08
In the
"standard model" of condensed matter physics, elementary energy carriers are
called quasiparticles. Understanding when and how these energy carriers fail to
perform their mission opens doors to new phenomena and may lead to new and
important discoveries in the atomic nano-world of condensed matter
materials.

RESEARCH REVEALS HIDDEN MAGNETISM IN SUPERCONDUCTIVITY, March 07
While
studying a compound made of the elements cerium- rhodium-indium, researchers at
Los Alamos National Laboratory and the University of Illinois at
Urbana-Champaign have discovered that a magnetic state can coexist with
superconductivity in a specific temperature and pressure range. The discovery is
a step toward a deeper understanding of how Nature is organized in regimes
ranging from the fabric of the cosmos to the most fundamental components of
elementary particles.

Z MACHINE EXCEEDS TWO BILLION DEGREES KELVIN: HOTTER THAN THE INTERIORS OF
STARS, March 08
Sandia's Z machine has produced plasmas that exceed
temperatures of 2 billion degrees Kelvin - hotter than the interiors of stars.
The unexpectedly hot output, if its cause were understood and harnessed, could
eventually mean that smaller, less costly nuclear fusion plants would produce
the same amount of energy as larger plants.

RESEARCHERS
WORKS ON SINGLE MOLECULAR DIODE, March 07
Researchers from the University of
South Florida, the University of Chicago and the Russian Academy of Sciences
(Moscow) have recently developed the principles of operation and completed an
experimental testing of a single molecule for use as a diode. A paper explaining
their research has just been accepted for publication in Physical Review Letters
by the American Physical Society.

NASA SURVEY CONFIRMS CLIMATE WARMING IMPACT ON POLAR ICE SHEETS, March 08
In
the most comprehensive survey ever undertaken of the massive ice sheets covering
both Greenland and Antarctica, NASA scientists confirm climate warming is
changing how much water remains locked in Earth's largest storehouses of ice and
snow.

LARGEST
AIR POLLUTION STUDY IS RELEASED, March 08
A study published Wednesday
suggests fine particulate air pollution spikes increase cardiovascular and
respiratory hospitalizations across the United States.

MOST
DISTANT COSMIC EXPLOSION WAS A STAR COLLAPSING INTO A BLACK HOLE, March 08
It came from the edge of the visible universe, the most distant explosion
ever detected. In this week's issue of Nature, scientists at Penn State
University and their U.S. and European colleagues discuss how this explosion,
detected on 4 September 2005, was the result of a massive star collapsing into a
black hole.

REINING IN CARBON DIOXIDE LEVELS IMPERATIVE BUT POSSIBLE, March 08
Implementing a plan to keep rising carbon dioxide levels from reaching
potentially dangerous levels could cost less than 1 percent of gross world
product as of 2050, a cost that is well within reach of developed and developing
nations alike. Moreover, without simultaneous progress in the way energy is
found, transformed, transported and used, the world is in danger of facing a
severe energy crisis sometime within the next century. Those are the conclusions
of a report by Klaus S. Lackner and Jeffrey D. Sachs of The Earth Institute that
appears in the most recent issue of Brookings Papers on Economic Activity
published by the Brookings Institute.
