Reported is a study of cold fusion in which trace amounts of helium, possible evidence of an actual fusion reaction, were found. Research methodology is detailed. The controversy over the validity of experimental results with cold fusion are reviewed. (CW)

Describes a tandem mirror concept for nuclear fusion. Its basic features is a solenoidal plasma plugged at both ends by "baseball magnets." Could become the basis for a future reactor. (GA)

Describes some of the atomic age memorabilia which are gathered in an exhibit at the National Museum of History and Technology. (CP)

Five issues concerning nuclear power--economics, danger from accidents, environmental effects, terrorism, and alternatives are debated, with one paragraph statements from opponents and advocates on each of the topics. (CP)

Mistakes related to the operation of nuclear power plants and other technologically complex systems are discussed. Recommendations are given for decreasing the chance of human error in the operation of nuclear plants. The causes of the Three Mile Island incident are presented in terms of the human error element.

Supersymmetry is a newly developed principle with which theorists are attempting to continue the work of unification. This article examines the principle of supersymmetry at the subatomic level and relates it to the quest for a unity theory. (MA)

Details are provided of the actions of the Atomic Energy Commission in response to the problem of radioactive wastes stockpiled at AEC-licensed uranium mill sites across eight western states. (DT)

Discusses the Weinberg-Salam theory of the weak and electromagnetic interactions which is an attempt at a partially unified theory for physics. (HM)
