    Physicists have coaxed ultracold atoms to migrate along the outside of a wire by sending a current through it, opening a new way to move such atoms around.

  • A tragic accident has claimed the life of Bjorn Wiik, director of Germany's DESY particle physics laboratory in Hamburg. "We have lost an important leader in the field of high-energy physics," says Burton Richter, who directs the Stanford Linear Accelerator Center.
