Science News February 28, 2004 Ivars Peterson	Heads or Tails? A new mathematical analysis now suggests that, in a typical toss, a coin is more likely to land on the same face as it started out on.
Technology Research News February 11, 2004	Electricity teleportation devised Researchers from Leiden University in the Netherlands have devised a way to teleport electricity.
Industrial Physicist Feb/Mar 2004 Jennifer Ouellette	Time-resolved spectroscopy comes of age It is possible to learn a lot about a sample by exciting it with a pulsed laser and using a very fast detector to measure the resulting emissions and decay as a function of time. Ultrafast lasers and pulse-shaping techniques have helped open up new applications.
Technology Research News January 28, 2004	Technique detects quantum state Researchers from the University of Rome in Italy have pushed theorized "perfect" quantum cryptography schemes forward by demonstrating a method for detecting quantum entanglement among subatomic particles.
Technology Research News January 14, 2004	Atoms make quantum coprocessor Researchers from Brussels Free University in Belgium (ULB) and the Niels Bohr Institute in Denmark have shown that the collective spin of clouds of atoms can be used to compute.
Science News January 10, 2004	Sounds of Music Interested in the relationship between musical instruments and the physics of sound? This Rice University Web site offers illustrated explanations of physics terms such as pitch, frequency, and standing waves. It also demonstrates tuning systems, intervals, octaves, and more.
Technology Research News December 31, 2003 Eric Smalley	Light frozen in place Researchers at Harvard University have trapped and held a light pulse still for a few hundredths of a millisecond.
Technology Research News December 3, 2003 Eric Smalley	Chaotic lasers lock messages Researchers from Advanced Telecommunications Research Institute International in Japan have found a way for two people in different locations to work out a cryptographic key using the signal from the rapidly and randomly fluctuating light signal of a chaotic laser.
Industrial Physicist Dec 2003/Jan 2004 Coleen Morrison	The Optical Society of America The Optical Society of America (OSA) began in 1916 in Rochester, New York, as a gathering of the field's leading scientists, who agreed to create an organization through which scientific ideas, interests, and discoveries could be shared. The society still adheres to its founders' original goals.
Technology Research News November 19, 2003 Kimberly Patch	Physics tackles processor problem The difference between problems that parallel processing computers are good at solving and those they are not is a bit like the difference between water and ice. Pinpointing the boundary between easy and hard parallel processing problems is a physics puzzle that could lead to better parallel processing software.
