Quantum Shot Noise
Fluctuations in the flow of electrons can signal the transition from particlelike to wavelike behavior and signify the nature of charge transport in mesoscopic systems. — Carlo Beenakker and Christian Schönenberger
Molecular Electronics
Improvements in our understanding of how molecules transport charge, and how they interface to the macroscopic world, are fueling new devices and applications. — James R. Heath and Mark A. Ratner
Middle-School Texts Don't Make the Grade 
Thousands of teachers are saddled with error-filled physical science textbooks that fail to present what science is all about. Physicists deserve some of the blame. — John Hubisz

Two-Ion Logic Gates Open the Way to Further Advances in Quantum Computing
Precisely controlled logic gates are key ingredients in quantum computers, which can easily outperform classical computers for some problems.
Cosmic-Ray Muons Might Help Thwart Transport of Concealed Fissile Material
Physicists at Los Alamos propose a new kind of surveillance imaging that avails itself of a ubiquitous natural flux of highly penetrating radiation.
Experiments Investigate the Behavior of Pores in Artificial Vesicles
Twenty-first century experimental techniques combine with 19th century theory to explore how cell membranes behave when breached.

Canada Catalyzes Research and Recruitment
Aggressive spending in Canada has spruced up research labs and promises an expansion of the Sudbury Neutrino Observatory, but it has also led to a time lag between setting up new equipment and finding money to maintain it.
Pentagon Revamps Nuclear Doctrine 
The US government's plan to overturn a ban on designing new nuclear weapons is generating controversy.
Three Millimeter Arrays Converge in Inyo Mountains
After announcing in 2000 that two California telescope arrays would be united at a fresh site in the state's Inyo mountains, the project's university partners finally have the formal agreement and most of the money to go ahead with the merger.
