  Search & Discovery
 
    New measurements hint at the presence of a volcano underneath the Greenland ice sheet.
 
    The atoms in a BEC assemble gregariously into a coherent whole, but in a periodic potential that's sufficiently strong, they can separate into an array of isolated atoms.
 
    Quantization imposes a lower limit on the energy of a neutron trapped in a gravitational potential well.
 
    Will some future light sources be based on linear accelerators rather than synchrotron storage rings?
  Issues & Events
 
    Famed for its fun, quirky, high-tech research and for zipping together industry and academia, the MIT Media Lab is expanding at home and abroad.
 
    The hundreds of millions of federal dollars that in past years supported training of elementary school math and science teachers have been redirected into new math and science partnerships, and the result may be less money for the teachers.
 
    In an old hematite mine far below the ragged landscape of Minnesota's Iron Range, workers have installed about one-quarter of the 486 octagonal steel "planes" that will make up the $40 million 5500-ton "far detector" for Fermilab's Main Injector Neutrino Oscillation Search experiment.
 
    US laboratories are installing the first batch of 900-megahertz (21-tesla) nuclear magnetic resonance (NMR) machines months ahead of their European and Japanese competitors.
 
    The Niels Bohr Archive in Copenhagen has posted on the Web 11 short documents, never before made public, relating to the controversial visit of Werner Heisenberg to Bohr in German occupied Denmark in 1941.
 
    The Kavli Institute for Theoretical Physics is how the Institute for Theoretical Physics at the University of California, Santa Barbara, will soon be known, thanks to a $7.5 million gift from local entrepreneur Fred Kavli.

Cover: Ultracold atoms can be trapped in this glass-cell vacuum chamber by magnetic fields from current-carrying coils positioned above and below. (The cell's front face is 26 mm square.) Researchers at the Max Planck Institute for Quantum Optics and the University of Munich induced atoms in this trap to undergo a quantum phase transition, with each phase marked by very different behavior. See the story on page 18. (Photo courtesy of the Philip Morris Foundation.)
