Geotimes May 2007 Kathryn Hansen	Deep Earth May Hold an Ocean Earth's deep interior, more than 1,000 kilometers below the surface in the mantle, could prove to be a watery place. That's the conclusion researchers drew from an anomaly uncovered by the first global map of Earth's lower mantle, using a new type of seismic analysis.
Geotimes May 2007 Carolyn Gramling	Lava Cooks up Carbon Nanotubes Mount Etna may be a fiery factory for one of the most sought-after tools of nanotechnology: tiny carbon nanotubes.
Geotimes May 2007 Carolyn Gramling	Slow Earthquakes, Tiny Tremors Small earthquakes and tiny tremors originating deep in fault zones are the result of slow earthquakes at Earth's surface, according to a new study.
Geotimes May 2007 Jessica F. Larsen	A Comment on... Volcanoes in a Changing Global Climate It is highly speculative at present to predict how global climate change will transform the science of volcanology. Yet it is important that we begin to anticipate how the impacts of volcanoes will change, as population and precipitation patterns adjust to climate change during the 21st century.
Geotimes May 2007 Josh Trapani	A Political Comment on ... Proposals to Regulate Greenhouse Gas Emissions in the 110th Congress Establishing a nationwide market-based system for greenhouse gases may be one of the most difficult legislative steps for Congress to take, due largely to the potential environmental, economic and social consequences.
IEEE Spectrum May 2007 William B. Gail	Climate Control We will be able to engineer the Earth to our liking -- but we'd better start now. Before we picked a climate, we would need to evolve the political, commercial, and academic institutions to get us there.
Chemistry World April 27, 2007 Richard Van Noorden	Scientists Clash Over Methane Mystery The startling claim that trees could be responsible for putting millions of tons of methane into the atmosphere every year was published last year in the prestigious journal Nature. But that has now been rubbished by rival researchers who report that plants emit virtually no methane whatsoever.
Chemistry World April 26, 2007 Philip Ball	Water's Surface is Acidic Pure, neutral water has an acid skin. This striking notion has now been confirmed by calculations and tests by an international team of scientists. The finding could be significant for a number of disciplines.
Geotimes April 2007 Jordan Clary	Exploring Karst in Guilin, China On first arriving in Guilin, China, you may feel like you have stumbled into J. R. R. Tolkien's Middle-earth. Guilin, however, is no trick of a novelist's imagination. Its more than 5,180 square kilometers of karst landscape is the result of a perfect alchemy of geological conditions.
Chemistry World April 18, 2007 Simon Hadlington	Bioethanol Fuel 'as Big a Health Risk as Gasoline' The use of ethanol as a gasoline substitute for motor vehicles may not be the environmental panacea that its proponents would have us believe, according to a U.S. atmospheric scientist.
