Technology Research News November 14, 2005	Quantum cryptography Quantum cryptography, which taps properties of photons to represent information, can, in theory, provide perfectly secure communications.
Scientific American November 14, 2005 Wendy M. Grossman	Wait a Second Official timekeeping may depend on atoms, not day-night cycles.
Science News November 5, 2005 Ivars Peterson	Climbing a Watery Slope Research by mathematicians involving the meniscus-climbing actions of water-walking insects sheds new light on fluid dynamics.
Registered Rep. November 1, 2005 John Churchill	Ion the Market United Dynamics' president forecasts stock market developments by measuring the level of positive and negative ions in the atmosphere, which allegedly effect the psychology of individuals.
Scientific American October 17, 2005 Graham P. Collins	Quantum Bug Physicists must overcome a fundamental obstacle before quantum computers can become a practical reality: decoherence, which is the loss of the very quantum properties that such computers would rely on.
Scientific American October 10, 2005 Alexander Hellemans	A Force to Reckon With What applied the brakes on Pioneer 10 and 11? A proposal to analyze telemetry from the early years could literally point toward the correct explanation.
IEEE Spectrum October 2005	The Weight of the World The 7000-ton Atlas detector at CERN, the European Organization for Nuclear Research, is the centerpiece of the biggest particle physics experiment ever undertaken.
Scientific American October 2005 Marguerite Holloway	The Beauty of Branes Lisa Randall's thinking on higher dimensions, warped space and membranes catalyzed ideas in cosmology and physics. It might even unify all four forces of nature.
Science News September 10, 2005 Ivars Peterson	Celestial Atomic Physics Objects in the solar system often have chaotic and unpredictable trajectories. This same uncertainty also appears in atomic and molecular systems.
Geotimes September 2005 Naomi Lubick	Supercomputer Models Earth's Magnetic Field A team of researchers has made a step toward modeling the Earth's chaotic magnetic field behavior using one of the largest supercomputers on the planet to run the most realistic model yet.
