PHYSICISTS SHOW COHERENCE OF BOSE-EINSTEIN CONDENSATES EXTENDS TO SPIN STATE OF ATOMS, November 10
New research shows that the unique properties of atomic Bose-Einstein
condensates extend to the internal spin states of the atoms from which
the condensates are formed. Bose-Einstein condensates are an unusual
form of matter in which all atoms exist in the same quantum state.

FLUIDS RACE THROUGH NEARLY FRICTIONLESS CARBON NANOTUBES, November 11
Within the cells of our bodies, fluids flow rapidly through
miniscule, nearly frictionless, protein channels. Until now, human-made
nanoscale structures have not been able to mimic those same speeds
because the fluids flow slowly along the walls of the tiny structures.

ARTICLE EXAMINES A DISPUTED EINSTEIN PAPER, November 11
Apparently, even Einstein wasn't always an "Einstein." A
University of Arkansas professor's article relates physicist Albert
Einstein's reaction to a negative critique on a paper he had written on
gravitational waves.

CENTRAL EUROPE GETTING WARMER, November 11
Surface temperature analysis of Central Europe shows that temperatures
there have risen three times faster than the Northern Hemisphere land
average.

MESSENGERS FROM THE EXTREME UNIVERSE, November 10
A unique observatory in a remote location in Argentina is
starting to unravel the mysteries of High Energy Cosmic Rays. There is
no scientific consensus on the source of these particles which the
shower the Earth at energies 10 million times higher than can be
produced in particle accelerators! But the Pierre Auger Observatory is
shedding new light on these energetic particles from space and using
them as messengers to tell us more about the wider Universe.
