• Mercury Atomic Clock Keeps Time with Record Accuracy
  An experimental atomic clock based on a single mercury atom is now at least five times more precise than the national standard clock based on a “fountain” of cesium atoms, according to a paper by physicists at National Institute of Standards and Technology (NIST) in Boulder, Colorado.  Their results were published in the July 14, 2006 issue of Physical Letters Review.
• Blueprint Brews 3D Band-gap Crystals
  A cookbook developed by University of Toronto researchers describes how to fabricate efficient, large-scale, three-dimensional photonic band-gap (PBG)crystals. PBG materials enable light from micro-lasers to carry information on-chip the way fiber optics uses light for communication between chips.

• New Atomic Clock Could Be 1,000 Times Better Than Today's Best
  Using sophisticated laser technology and a lone atom of mercury, Scientists at the National Institute of Standard and Technology (NIST) in Boulder, Colorado, developed a new type of atomic clock that produces about 1 quadrillion "ticks" per second and promises to be far more accurate than the current top standard in time measurement - cesium-based microwave atomic clocks.
