Neutrinos are perhaps the least understood of the known denizens of the subatomic world. They have nearly no mass, interact only via the weak nuclear force and gravity, and, perhaps most surprising, the three known species of neutrinos can transform from one variant into another. This transformation, called neutrino oscillation, has been…

When the sun rose over America on July 4, 2012, the world of science had radically changed. The Higgs boson had been discovered. Mind you, the press releases were more cautious than that, with "a new particle consistent with being the Higgs boson" being the carefully constructed phrase of the day. But, make no mistake, champagne corks…

Gives an analogy useful for explaining the experimental teleportation of a quantum-mechanical state to beginning physics students. (WRM)

Discusses the existence of matter in smaller groups known as clusters. Applications of the findings in scientific studies are presented as they relate to technology. (SA)

Discusses the contributions made by the field of quantum electrodynamics to the understanding of positroniums. (MLH)

Detection of neutrino decay may have profound consequences for both particle physics and cosmology, providing a deep connection between physics of the very large and physics of the very small. Describes this link and discusses the nature and status of the search for decaying neutrinos. (Author/JN)
