Decapitation and rebirth
05-29-2007 · EurekAlert!
Images of disembodied heads are widespread in the art of Nasca, a culture based in Peru from AD 1 to AD 750. But despite this evidence and large numbers of trophy heads in the region’s archaeological record, only eight headless bodies have been recovered with evidence of decapitation. An analysis of a headless body from the site of La Tiza provides important new data on decapitation and its relationship to ancient ideas of death and regeneration.

NRL sensor to measure natural airglow in the upper atmosphere
11-06-2006 · EurekAlert!
The second of five Special Sensor Ultraviolet Limb Imager remote sensing instruments, developed by the Naval Research Laboratory, was launched on Nov. 4, 2006 on board the DMSP F-17 satellite. SSULI is the first operational instrument of its kind and provides a new technique for remote sensing of the ionosphere and thermosphere from space. SSULI's measurements will provide scientific data supporting military and civil systems and will assist in predicting atmospheric drag effects on satellites and re-entry vehicles.

Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.
