 LithosphereVisualizing the imprints of past and present Earth dynamics New Lithosphere articles posted online May 16, 2012, report on (1) seismic anisotropy measured beneath 14 broadband stations in southeastern India; why geoscientists should persist in their efforts to reach and study such spectacular sub-sea geologic features as the Mariana Trench (recently explored by film director James Cameron) and how "land geologists" can help this effort by studying on-land equivalents like ophiolites; and (3) pressures and melting temperatures of sediments deeply buried in Earth's mantle.

Environmental Science and TechnologyTrashing old, unused medications best for reducing environmental impact A new study suggests that dumping old or unneeded medications in the trash can may be the best way to reduce the environmental impact of the 200 million pounds of pharmaceuticals that go unused in the US each year. The report, which weighs the emissions from flushing, incinerating or trashing drugs, appears in ACS' journal Environmental Science and Technology. Contact: Michael Bernstein

The HoloceneAncient tree-ring records from Southwest US suggest today's megafires are truly unusual Today's mega forest fires of the southwestern U.S. are truly unusual and exceptional in the long-term record, suggests an unprecedented study that examined 1,500 years of ancient tree ring and fire data from two distinct climate periods. Researchers constructed and analyzed a statistical model and found that today's dry, hot climate combined with the past century of human fire suppression is causing megafires, said study co-author and fire anthropologist Christopher Roos, Southern Methodist University, Dallas.

NatureManmade pollutants may be driving Earth's tropical belt expansion Research led by the University of California, Riverside, shows that black carbon aerosols (tiny carbon particles produced from biomass burning and incomplete combustion of fossil fuels) and tropospheric ozone, both manmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere. The researchers caution that an unabated tropical belt expansion would impact large-scale atmospheric circulation, especially in the subtropics and mid-latitudes.

JAMABeijing Olympics study reveals biological link between air pollution, cardiovascular disease Using the 2008 Beijing Olympics as their laboratory, USC researchers found biological evidence that even a short-term reduction in air pollution exposure improves one's cardiovascular health. Short-term reduction in air pollution during the 2008 Beijing Olympics led to acute improvement in biomarkers of systemic inflammation.

Atmospheric Environment Scientists 'read' the ash from the Icelandic volcano 2 years after its eruption In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena. Contact: SINC
