June 2009, Vol. 5, No. 3
Most gems are natural minerals, which, although scarce and small, have a major impact on society. Their value is directly related to proper identification. The determination of the species is key, of course, and must be done non-destructively. This is where classical tools of mineralogy come into play. However, other issues are paramount: Has this gem been treated? Is it natural or was it grown in a laboratory? For certain varieties, being able to tell the geographical provenance may enhance value considerably. These issues necessitate cross-linking the formation of gems with their trace-element chemistry. These unusual mineralogical and geochemical challenges make the specificity of gemology, a new and growing science, one of the possible futures of mineralogy.

The Nuclear Fuel Cycle – Environmental Aspects, December 2006, Vol. 2, No. 6
$20.00Increasing concerns for the effects of global warming that result from rising greenhouse gas concentrations in the atmosphere have led to a reexamination, even enthusiasm, for nuclear power. Of all the current alternatives to fossil fuels, nuclear fission is the most important source of energy, accounting for 17 percent of the world’s electricity.

Supervolcanoes, February 2008, Vol. 4, No. 1
$20.00Explosive super-eruptions from large volume, shallow magma systems lead to enormous and devastating pyroclastic flows, the formation of gigantic collapse calderas, and deposition of volcanic ash over continent-sized areas. Recognition that future eruptions from these “supervolcanoes” will undoubtedly have severe impacts on society—and perhaps on life itself—has led to recent public and media interest.
