Geotimes November 2007 Carolyn Gramling	Acid Rain Alters Coastal Waters Excess carbon dioxide, sulfur and nitrogen from fossil fuel burning, agricultural runoff and other human sources are changing ocean chemistry -- and that impact is especially pronounced along the coasts, new research suggests.
Geotimes November 2007 Carolyn Gramling	How Does Your Continent Grow? Data from ancient mantle rocks are helping to shore up the hypothesis that the continental crust was extracted in pulses, during periodic large melting events in the mantle.
Geotimes November 2007 Erin Wayman	Sudden Climate Change Not Neanderthals' Downfall New research suggests abrupt climate change is not to blame for the extinction of Neanderthals. Instead, competition from modern humans probably played a large role.
Geotimes November 2007 Nicole Branan	Water Pours Through Pores in Sea Ice Scientists have come up with a new model that describes how water moves through the Arctic sea ice beneath melt ponds, helping them to make better climate predictions.
Geotimes November 2007 Carolyn Gramling	Tsunami Risk High in Myanmar Once thought to be relatively seismically quiet, the northern part of the Bay of Bengal may instead be prone to giant earthquakes that could spawn tsunamis, with potentially devastating consequences for the bay's densely populated coasts, according to a new study.
Geotimes November 2007 Erin Wayman	Using Wine "Goggles" to Find Minerals Researchers recently learned that soft drinks, wine and even beer can be used to detect metals in soil samples, demonstrating that these common beverages are just as good as, if not better than, the more traditional geochemical analyses used to find mineral deposits.
Geotimes November 2007 Jim Gibeaut	Coastal Development: The Galveston Case, Part II Whatever the choice, it is clear that we need to build into our policies a dynamic that matches the changing conditions along our coast, and we need to make sure the public is aware of the situation.
Geotimes October 2007 Fred Schwab	Flicking Out on Mother Earth Movies may be the most cost-effective way to raise awareness of an issue and stimulate action. The geological community seems to have gotten the message.
IEEE Spectrum October 2007 Saswato R. Das	Military Experiments Target the Van Allen Belts The US armed forces will test whether RF injections into the ionosphere could halt geomagnetic storms.
Chemistry World October 15, 2007 Jonathan Edwards	GM Trees Clean Pollutants From Air and Soil Scientists have genetically modified plants to remove and destroy a range of toxic and carcinogenic chemicals from water and air. Cleanup costs billions of pounds globally each year -- now some contaminated areas could be cleaned up quickly and safely by planting trees.
